Installing Laravel and Composer on the cPanel server

Laravel is a free and open source PHP framework for developing web applications. Some of the features of Laravel are a modular packaging system with a dedicated dependency manager, different methods for accessing relational databases. Laravel, along with Symfony2, Nette, CodeIgniter, Yii2, etc., is known as one of the most popular PHP frameworks. Laravel tries to make things easier by reducing common tasks used in most web projects, such as authentication, routing, sessions, queuing and caching. Laravel provides the powerful tools needed for large and robust applications. It supports multiple platforms and allows users to develop MVC web applications.

Server requirements

The Laravel framework has several system items. You need to make sure that your server meets the following conditions:

PHP >= 5.6.4
OpenSSL PHP Extension
PDO PHP Extension
Mbstring PHP Extension
Tokenizer PHP Extension
XML PHP Extension
Automatic installation of Laravel via Softaculous installation script

Laravel can be installed automatically on cPanel server using Softaculous script installer software. Log in to cPanel and find the Softaculous menu under Software and Services. Once done, you will be redirected to the Softaculous home page. Type Laravel in the search bar and click on the result. Go to the Install tab, where you will be asked to select the folder where Laravel will be installed. Feel free to choose the directory you need (note that this directory will be created by Softaculous). This is the easiest way to install Laravel.

Manual installation of Laravel

Laravel uses Composer to manage its dependencies. Before using Laravel, make sure you have Composer installed on your machine. It is a tool for dependency management in PHP. It allows you to install the libraries your project depends on and manages them for you. Run the following commands to install Composer and SSH on the server.

cd / bin

Before installing, let’s check your compatibility using the command below.

php installer –check
All settings correct for using Composer

If everything looks good, let’s install Composer.

php installer
Composer successfully installed to: /bin/composer.phar
Use it: php composer.phar

Now that Composer is installed, we can uninstall the installer.

rm -f installer

Now we can use this Composer to install Laravel. Run the following command to install Laravel.

php /bin/composer.phar create-project laravel/laravel –prefer-dist

After installing Laravel,

Connect Laravel’s public directory to the public_html folder as a symbolic link like the code below:

rm -rf public_html
ln -s laravel/public/ public_html

After all the installation steps, open the browser and go to the relevant domain. Installation is complete and some configuration settings are required.

Laravel configuration settings

Public Directory

After installing Laravel, you need to configure the document/web root of your web server as a public directory. index.php in this directory is the front controller for all incoming HTTP requests to your application.

Configuration files

All Laravel framework configuration files are stored in the config directory. Each option is documented, so feel free to browse through the files and familiarize yourself with the options available to you.
Directory permissions

After installing Laravel, you may need to configure some permissions. The directories in the cache directory and bootstrap/cache folders must be writable by your web server, otherwise Laravel will not run. If you are using a Homestead virtual machine, these permissions must already be set.

How to install NMAP on Linux?

Network Mapper, abbreviated as NMAP, is an open-source security diagnostic and network inspection tool. This software is designed for fast scanning of large networks, but it also works well on single hosts. NMAP uses raw IP packets in a new way to determine what hosts are available on the network, what services these hosts provide (application name and version), what operating systems they run (what version), what They have filter/firewall package type and many other features. Although NAMP is used for security inspections, many users also use it for routine tasks; Such as network management, service upgrade scheduling management, and hosting or service access time monitoring.


Installing NMAP on Linux

Follow the command below to install NMAP:

Increasing Linux server security

What are the solutions to increase the security of the Linux server? A Linux server is a server on which one of the distributions of the Linux operating system is installed. This server can be considered a type of computer always connected to the Internet, which has a special type of software and hardware. If you also use a Linux server, increasing its security is definitely one of your concerns. Although one of the main reasons for people’s acceptance of Linux servers is their high security, there are solutions with the help of which you can improve this security to the maximum extent.

But why is security so important in Linux servers? Linux server can be used for web hosting, mail server, file storage, etc. That is why it is very important to talk about high security in these servers. One of the advantages of Linux is its open source. Therefore, its security bugs are easily identified and fixed. Considering that hackers may always be able to find a way to infiltrate your server and system, it is essential to strengthen the security layers of your Linux server in several ways. In this article, we have mentioned 13 of the most practical possible solutions to increase the security of the Linux server.

Solutions to increase Linux server security

In what ways can we improve the security of the Linux server? Although one of the main features of Linux is its high security, but for your peace of mind, you have the possibility to adjust the security of this server according to your needs through solutions. Since hackers can always find a way, it is not bad to know these solutions and by doing them, try to improve the security of your Linux server to the maximum extent. In the following, we will introduce 13 practical solutions.

1. Enable open_basedir

One of the ways to increase the security of this server is to activate one of the php services called open_basedir. This system is a kind of security feature in PHP that prevents hackers. With the help of open_basedir, it is possible to make the access of a user through php only limited to the same user. In other words, when a hacker succeeds in penetrating a part of the server, if this feature is enabled, the hacker’s access is limited to that part and he cannot access other parts of the server.

2. Taking help from safe_mode

You are probably familiar with the Safe Mode status on your mobile phone. But this feature is not specific to mobile phones and is also available for operating systems. This mode is designed to remove malicious programs, viruses, find software errors, restore operating system settings, etc. In simpler words, it can be said that Safe Mode is a state of the operating system in which, if it is active, only essential files can be executed.

Enabling safe mode prevents malicious programs from running. If a malicious program is installed on your Linux server, it will run every time Windows boots. Most viruses and malicious programs that infiltrate systems with the intention of hacking servers are designed in such a way that they can disable or remove antiviruses. Therefore, if a malicious program has entered the server, the best solution to prevent it from running is to set Windows to safe mode.


3. Disabling remote code execution

One of the methods that hackers use to break into systems is to execute code remotely in the desktop service, which is called Remote Desktop Services. A hacker can run any code they want on your system. For example, it can install its own malicious programs on the server, and in this way, it can learn about the server’s data and even change them. To increase the security of the Linux server, it is better to disable Remote Desktop Services. In general, deactivating services that do not work for the system increases its security.

4. Disable display_error

Display error is a type of error report in php that some programmers activate with the intention of viewing and being informed of php errors. Due to security issues, it is better to disable this service because its activation makes it easier for unauthorized attackers to penetrate the server. Therefore, if you are looking for a way to improve the security of your Linux server, we recommend that you disable this error report and use another solution to view php errors.

5. Input size limitation

One of the ways to increase Linux security and prevent web attacks is to limit the input size. But what does limiting the input size mean? As you probably know, in the php language and in the post method, the data in the HTTP request is hidden in the header.

Sending malicious codes in parts of the site that takes input from the user on the post method is one of the hackers’ methods to penetrate the system. In such a situation, if you limit the input size in the config file, you can prevent attackers from sending these malicious codes.

6. Resource limitation

DOS attacks, which are shortened to Denial of Service attack, are known as Denial of Service attacks. These attacks are carried out by attackers or hackers. The purpose of these attacks is to temporarily or permanently suspend or interrupt the services of the servers hosting a site. One of the solutions that can be used to protect against these attacks to some extent and ensure the security of the Linux server is limiting resources.

7. Disabling some functions

Another way to prevent web attacks is to disable some functions. If you are using shared servers, it is better to close the functions that are threatening to the Linux server. Some of these functions are:

  • curl_multi_info_read
  • curl_multi_init
  • curl_multi_remove_handle
  • curl_multi_select

These functions are located in a file called php.ini.

8. Using the magic_quotes_gps function

Inputs that are sent from the user side to the server may be a security bug for the server for various reasons. Therefore, one of the things that can be done to increase the security of the Linux server is to use the magicquotesgpc function. This function provides the programmer or site developers with the ability to secure user-side inputs to the server to a great extent. To activate and use this function, you must access the php.ini file.


9. Disable expose_php

One of the ways to prevent attackers and hackers from infiltrating the server is to prevent them from accessing our server facilities. But how can this be done? Note that whenever php starts, it adds a message containing its version number to the server header. In order to hide this data from hackers, you can set the expose_PHP variable to off. By disabling this feature, the data and web server facilities are not easily available to hackers.

10. Installation of CSF firewall

As another way to increase Linux server security, you can install CSF firewalls, which are also known as firewalls. This system can be considered as one of the best server security services that have been very successful in its kind so far. If you are looking for one of the strictest security elements to improve server security, be sure to install CSF Firewall. As the name suggests, this system works exactly like a firewall.

In other words, after installation, at the entrance of a server, it carefully checks all incoming requests to it. You can enable any security settings you want on the firewall. After that, if any of the incoming requests to the server contradicts the information and settings registered in the firewall, the requests are deleted and prevented from being sent to the server. A firewall is powerful enough to filter and process thousands of gigabytes of data in just a fraction of a second.

11. Installation and configuration of CLAMAV antivirus

If you are looking for one of the best antivirus for Linux operating system, install CLAMAV Antivirus, which has the ability to detect a large number of viruses at the same time. Another advantage of this antivirus is that it is free. In addition to this, the database of this antivirus can be updated automatically. Despite the powerful tools such as the scanner provided by this antivirus, you no longer need to use graphical environments to scan your server; Rather, you can scan the server with the help of this antivirus’s own scanner. Installing CLAMAV antivirus is recommended as one of the ways to increase Linux server security.


12. Installing the ModSecurity module

ModSecurity module is a firewall that is installed on the hosting servers. Along with other software and hardware firewalls that you install to keep your server secure, adding this module can also act as a double layer of security. This module is able to control various attacks on the server to a great extent. Note that installing the security mode module alone is not enough to maintain the security of the server, but this module should be used along with other security firewalls to increase the site’s security level.

One of the positive features of this module is its programming power. The security mode can identify and block things that have already damaged the security of the site. Among the applications of this security module, the following can be mentioned:

  • Ability to detect malicious bots and block them
  • Checking any requests sent to the site, such as membership requests from the user
  • Managing site traffic and checking them to ensure the absence of any security bugs
  • Preventing the uploading of some files and managing any uploaded files on the site
  • Managing the execution of commands and preventing the execution of malicious commands

13. Install CXS

As the last way to increase the security of the Linux server in this article, we should mention the installation of CSX. ConfigServer eXploit Scanner is a tool that can scan all files uploaded to the server. You can use this tool to prevent unauthorized attackers from exploiting the site and Linux server. The following are the positive features of this tool that help to maintain the security of the Linux server:

  • CSX tool is able to block loading of suspicious PHP and Perl scripts. These downloads are usually done with the purpose of sending spam or malicious attacks.
  • It has the ability to identify uploaded roots in user accounts.
  • It is able to increase the efficiency and scalability of the server.

How to configure Static IP address in Ubuntu 20.04

Typically, in most network configurations, IP addresses are dynamically assigned by a DHCP server. Static IP address setting may be required in various situations such as port forwarding configuration or media server implementation. Join us in this tutorial to introduce you to how to configure Static IP address in Ubuntu 20.04.

Static IP address configuration using DHCP:

The easiest and most recommended way to assign a static IP address to a device on your LAN is to configure static DHCP on your router. Static DHCP or DHCP reservation is a feature found on most routers that causes the DHCP server to automatically assign an IP address to a dedicated network device each time the device requests an address from the DHCP server. It works by assigning a static IP to a device’s unique MAC address. DHCP reservation configuration steps vary from router to router.


Ubuntu 17.10 and later versions use Netplan as the default network management tool. Previous versions of Ubuntu used ifconfig and its configuration file /etc/network/interfaces for network configuration. Netplan configuration files are written with YAML command with .yaml file extension. To configure a network card with Netplan, you need to create a YAML description for the network card, and Netplan will create the required configuration files for the selected provider tool. Netplan supports two providers, NetworkManager and Systemd-networkd. NetworkManager is mostly used on desktop machines, while Systemd-networkd is used on non-GUI servers.

Static IP address configuration on Ubuntu server:

In Ubuntu 20.04, the system identifies NICs using “predictable NIC names”. The first step to setting up a static IP address is to identify the name of the Ethernet card you want to configure. To do this, use the ip link command:

ip link

The command displays a list of all available network cards. In this example, the user card name is ens3:

۱: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000      link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00  ۲: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000      link/ether 08:00:27:6c:13:63 brd ff:ff:ff:ff:ff:ff

Netplan configuration files are stored in /etc/netplan directory. You will probably find one or more YAML files in this directory. The file name may be different in different systems. Usually the file name is 01-netcfg.yaml, 50-cloud-init.yaml or NN_interfaceName.yaml, but it may be different on your system. If your Ubuntu cloud instance has cloud-init, you need to disable it. To do this, create the following file:

sudo nano /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg
network: {config: disabled}

To assign a static IP address on the network card, open the YAML configuration file with your text editor:

sudo nano /etc/netplan/01-netcfg.yaml
network:    version: 2    renderer: networkd    ethernets:      ens3:        dhcp4: yes

Before changing the config, let’s briefly explain the code.

Each Netplan Yaml file starts with a network key that contains at least two required elements. The first required element is the version of the network config template and the second is the device type. The device type can be ethernets, bonds, bridges, or vlans. Under Device type (ethernets), you can specify one or more network interfaces. In this example, we have only one ens3 interface configured to obtain an IP address from a DHCP4 server: dhcp4:yes.

To assign a static IP address to the ens3 interface, edit the file as follows:

  • Set DHCP to dhcp4:no.
  • Specify a static IP address. Under Addresses: you can add one or more IPv4 or IPv6 IP addresses that will be assigned to the network interface.
  • Specify the gateway.
  • Under nameservers, set the nameservers IP addresses.
network:  version: 2  renderer: networkd  ethernets:  ens3:  dhcp4: no  addresses:  - ۱۹۲٫۱۶۸٫۱۲۱٫۲۲۱/۲۴  gateway4:  nameservers:  addresses: [,]

When editing Yaml files, make sure you follow YAML code indentation standards. If it is not true, the changes will not be applied. After finishing the work, save the file and apply the changes by running the following command:

sudo netplan apply
Confirm the changes by typing the following commands:
ip addr show dev ens3
۲: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000      link/ether 08:00:27:6c:13:63 brd ff:ff:ff:ff:ff:ff      inet brd scope global dynamic ens3         valid_lft 3575sec preferred_lft 3575sec      inet6 fe80::5054:ff:feb0:f500/64 scope link          valid_lft forever preferred_lft forever

You have assigned a static IP to your Ubuntu server.

Fixed IP address configuration in Ubuntu desktop:

Setting up a static IP address on Ubuntu desktops requires no technical knowledge.

On the Activities page, search for “settings” and click on the icon. This will open the GNOME Settings window. Click on Network or Wi-Fi depending on the interface you want to change. Click the cog icon next to the interface name to open interface settings. In the “IPV4” tab, select the “Manual” method and enter your static IP address, Netmask and Gateway. When you are done, click the “Apply” button.

ip addr

The output shows the IP address of the network card:

...  ۲: wlp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000      link/ether 50:5b:c2:d8:59:7d brd ff:ff:ff:ff:ff:ff      inet brd scope global dynamic noprefixroute wlp1s0         valid_lft 38963sec preferred_lft 38963sec      inet6 fe80::45e3:7bc:a029:664/64 scope link noprefixroute 

Conclusion :

We have shown you how to configure a static IP address in Ubuntu 20.04.

Setting up a permanent DNS address server on Ubuntu and Debian Linux

In this tutorial, we will look at how to install and use the resolvconf program to set a permanent DNS address server in the /etc/resolv.conf file on Debian and Ubuntu Linux distributions. Stay with us.

/etc/resolv.conf is the main configuration file for the DNS name resolver library. A resolver is actually a set of functions in the C library that provides access to the Internet’s Domain Naming System , or DNS. These functions are set to check the entries in the /etc/hosts file or some DNS name servers or to use the network information database service or NIC.

On modern Linux-based systems that use the system management tool and systemd service, DNS or name resolution services are provided to help local applications using the systemd-resolved service. By default, this service has four different modes to manage domain name analysis. Also, by default, the systemd DNS stub file at /run/systemd/resolve/stub-resolv.conf is used.

The file contains the local address as the only DNS server. This address refers to the /etc/resolv.conf file, which is used by the system to add server titles.

If you run the following ls command for /etc/resolv.conf, you will see that this file is a symlink to the /run/systemd/resolve/stub-resolv.conf file.

$ ls -l /etc/resolv.conf
lrwxrwxrwx 1 root root 39 Feb 15  2019 /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf

Of course, considering that /etc/resolv.conf is indirectly managed by the systemd-resolved service and in some cases is under the control of the network service (by initscripts or NetworkManager), any manual changes by the user cannot be permanent. or stored for a certain period of time.

Why should we edit the /etc/resolv.conf file?

The main reason for this is that the system’s DNS settings are usually not set correctly. You may also prefer to use your own server titles. The following cat command will show the default server address in the /etc/resolv.conf file on the sample Ubuntu system.

$ cat /etc/resolv.conf

Check DNS name servers

Here, when local applications such as the APT package management tool try to access FQDNs on the local network, the result will contain the error message “Temporary failure in name resolution” as shown in the image below.

Temporary problem in DNS server title parsing

The same thing happens when using the ping command.

$ ping

Temporary problem in name parsing

Therefore, when a user tries to manually configure DNS address servers, these changes will not be permanent. In fact, these settings will be lost after a single system restart. To overcome this problem, you can install the reolvconf tool so that you can apply the changes permanently.

In order to install the resolvconf package, you must first manually configure all DNS address servers in the /etc/resolv.conf file. This way you can access FQDMs of Ubuntu source servers on the Internet.


Installing resolvconf on Ubuntu and Debian

First, we update the system software packages. Then we will install resolvconf from official sources using the following commands.

$ sudo apt update
$ sudo apt install resolvconf

When the resolvconf tool installation is finished, systemd will automatically run and enable resolvconf.service. You can use the following command to check the status of this service.

$ sudo systemctl status resolvconf.service

If this service does not start and is not activated automatically for any reason, you can run and activate it using the following commands.

$ sudo systemctl start resolvconf.service
$ sudo systemctl enable resolvconf.service
$ sudo systemctl status resolvconf.service

Checking the service status of the resolvconf tool

Setting permanent DNS server address in Ubuntu and Debian

Then it’s time to set the configuration file /etc/resolvconf/resolv.conf.d/head.

$ sudo nano /etc/resolvconf/resolv.conf.d/head

Add the following in it.


Setting permanent DNS address server in Resolvconf

Now save the changes and restart the resolvconf.service. You can also reboot the system.

$ sudo systemctl start resolvconf.service

Now by checking the /etc/resolv.conf file you will notice that the imported title servers are permanently stored in it. From now on, there will be no problem in resolving the DNS server name in your system.
