In order to use MongoDB for our projects, we will first need to install it on our system along with its dependencies and some other tools. In this post, we will learn to install and set up Apache, PHP, and MongoDB on Ubuntu and Debian operating systems.

Installing Apache

First of all, we will install Apache on our system. Apache is a web server software and a popular HTTP client; it helps in creating virtual hosts. To install Apache on our system we will use the below-given command:

sudo apt update 
sudo apt install apache2 -y 

Note: The commands given in this article will work on both Ubuntu and Debian as both of them use the same package manager.

Installing PHP

To install PHP along with its common modules on our system we just need to run a simple command:

sudo apt install -y php7.4 libapache2-mod-php7.4 

We have installed PHP 7.4 on our system. You can install the version and the modules that you require for your project.

Installing MongoDB

Unfortunately, MongoDB is not available in the default repositories of Ubuntu and Debian. So we will have to first import the public key which will be used by the package management system:

wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add - 

If the terminal gives an error while executing the above-given command then you will have to install GnuPG on your system before executing this command again.

The next step is to create a list file for your version of the operating system. As I am running Ubuntu 20.04, I will run the following command:

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list 

For Debian 10:

echo "deb http://repo.mongodb.org/apt/debian buster/mongodb-org/5.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list 

Next, we need to reload the local package database and then install the latest stable release of Mongodb:

sudo apt update 
sudo apt install -y mongodb-org 

This will install the MongoDB server on your system.

Installing MongoDB PHP Module

For the last step, we need to install the MongoDB PHP module which is required for connecting PHP with MongoDB.

sudo apt install php7.4-mongodb 

Make sure to install the MongoDB module for the same version of PHP.

Run the following command to check the MongoDB module is enabled for the PHP CLI environment.

php -m | grep mongo 

Output
mongodb

Next, restart the Apache server to apply changes.

sudo systemctl restart apache2 

You can also create a phpinfo() file at the Apache document root. When you access this file in web broser,

Conclusion

MongoDB is a well-known, high-performance, NoSQL database. It is highly scalable and is different from Relational Database Systems such as MySQL and PostgreSQL. In this post, we learned how to install it along with its dependencies and other related tools.

Prerequsities

• The newly installed system’s recommended to follow initial server setup.
• Shell access to the CentOS 8 system with sudo privileges account.

Step 1 – Install Nginx

The Nginx packages are available under the default AppStream repository. You can simply update the DNF cache and install Nginx web server packages using the following commands.

sudo dnf update 
sudo dnf install nginx

After installation of packages starts Nginx service, Also enable Nginx service to auto-start on system boot.

sudo systemctl enable nginx
sudo systemctl start nginx

Step 2 – Install PHP with PHP-FPM

The Remi repository contains the latest PHP packages for the CentOS 8 Linux system. So first of all, you need to add the REMI repository to your system. Just execute the following command to add the repository.

sudo dnf install dnf-utils http://rpms.remirepo.net/enterprise/remi-release-8.rpm

Then enable the required DNF module for PHP installation. Here we are enabling the module for installing PHP 7.4. You can change this to PHP 7.3 or PHP 7.2 as per your requirements.

sudo dnf module reset php
sudo dnf module enable php:remi-7.4

Now, install the PHP on your system. As we are going to use FastCGI Process Manager (FPM) for this setup. So install the php-fpm package as well.

sudo dnf update
sudo dnf install php php-fpm  php-gd php-mysqlnd

You may also require some more PHP modules, So install them before going next. After completing PHP installation enable PHP-FPM service and start it.

sudo systemctl enable php-fpm
sudo systemctl start php-fpm

Make sure the php-fpm service is running.

sudo systemctl status php-fpm

Dec 09 21:44:57 tecadmin.example.com systemd[1]: Started The PHP FastCGI Process Manager.

Step 3 – Configure PHP-FPM

At this step, you have installed all the required packages. Let’s start the configuration process. First, edit PHP-FPM configuration file:

sudo vim /etc/php-fpm.d/www.conf

Make the changes like below. The latest versions of Nginx can connect to the socket using a proxy. So make sure listen is set to a socket file.

Then set user and group the same as Nginx server using. If you need to connect FPM from a remote system change listen.allowed_clients to LAN IP instead of 127.0.0.1.

; listen = 127.0.0.1:9000
listen = /run/php-fpm/www.sock

user = www-data
group = www-data

listen.allowed_clients = 127.0.0.1
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
pm = dynamic

After making changes restart the php-fpm service to apply changes.

sudo systemctl restart php-fpm

Step 4 – Create Nginx Server Block

Now, create a server block in Nginx for your domain and configure it to use php-fpm for processing PHP files. Create a server block file and edit in a text editor:

sudo vim /etc/nginx/conf.d/example.com.conf

Now added proxy configuration using a socket file. Also configured all PHP script to use fpm handler for execution.

server {
	listen       80 default_server;
	server_name  example.com www.example.com;
	root         /var/www/html;

	# Load configuration files for the default server block.
	include /etc/nginx/default.d/*.conf;

	location / {
	}

	location ~* \.php$ {
		# With php-fpm unix sockets
		fastcgi_pass unix:/run/php-fpm/www.sock;
		include         fastcgi_params;
		fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
		fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
	}
}

Save the server block configuration file and restart the Nginx service to apply changes.

sudo systemctl restart nginx

Step 5 – Enable Firewall Rules

Your server is ready to serve the application. If there is a firewall enabled on your system, make sure HTTP ports are open to access from remote systems.

The following commands will open the required ports for you.

sudo firewall-cmd --zone=public --permanent --add-service=http
sudo firewall-cmd --zone=public --permanent --add-service=https
sudo firewall-cmd --reload

Step 6 – Test Setup

All done. To test the environment, create a PHP script with phpinfo() function. Place this file to your server document root. Use the below command to do this.

echo "<?php phpinfo(); ?>" > /var/www/html/info.php

Then access info.php using server IP address (for default VirtualHost) for your configured domain in the Nginx server block.

http://localhost/info.php

Slide down the page and check value of $_SERVER[‘SERVER_SOFTWARE’] under PHP Variables section. This will show you the Web server name running on.

Conclusion

You have successfully configured an Nginx with PHP-FPM on your CentOS 8 or RHEL 8 Linux system. You can now host a website from your server.

Prerequsities

• Shell access to the CentOS 8 system with sudo privileges account.
• Complete initial server setup for newly installed systems.

Step 1 – Install Apache

The Apache packages are available under the default AppStream repository. You can simply update the DNF cache and install Apache web server packages using the following commands.

sudo dnf update 
sudo dnf install httpd httpd-tools mod_ssl

The mod_ssl package provides the functionality to use an SSL certificate for secure HTTP. After installation, enable the httpd service and start.

sudo systemctl enable httpd
sudo systemctl start httpd

Step 2 – Install PHP with PHP-FPM

The Remi repository contains the latest PHP packages for the CentOS 8 Linux system. So first of all, you need to add the REMI repository to your system. Just execute the following command to add the repository.

sudo dnf install dnf-utils http://rpms.remirepo.net/enterprise/remi-release-8.rpm

Then enable the required DNF module for PHP installation. Here we are enabling the module for installing PHP 7.4. You can change this to PHP 7.3 or PHP 7.2 as per your requirements.

Step 3 – Configure PHP-FPM

At this step, you have installed all the required packages. Let’s start the configuration process. First, edit PHP-FPM configuration file for Apache:

sudo vim /etc/php-fpm.d/www.conf

Make the changes like below. The latest versions of Apache can connect to the socket using a proxy. So make sure listen is set to a socket file.

Then set user and group the same as Apache server using. If you need to connect FPM from a remote system change listen.allowed_clients to LAN IP instead of 127.0.0.1.

; listen = 127.0.0.1:9000
listen = /run/php-fpm/www.sock

user = apache
group = apache

listen.allowed_clients = 127.0.0.1
listen.owner = apache
listen.group = apache
listen.mode = 0660
pm = dynamic

After making changes restart the php-fpm service to apply changes.

sudo systemctl restart php-fpm

Step 4 – Create Apache VirtualHost

Now, the time is to configure Apache to use php-fpm for processing PHP files. Here is two options, Either you use FPM as default for all virtual hosts or you can specifically configure Virtual host to use FPM. In this way, other virtual hosts will not be affected.

For this example, I am configuring FPM for a specific virtual host only. So edited configuration file in text editor:

sudo vim /etc/httpd/conf.d/example.com.conf

Now added proxy configuration using a socket file. Also configured all PHP script to use fpm handler for execution.

<VirtualHost *:80>
    ServerAdmin admin@example.com
    DocumentRoot /var/www/html

    ServerName example.com
    ServerAlias www.example.com

    # Proxy declaration
    <Proxy "unix:/run/php-fpm/www.sock|fcgi://php-fpm">
       # we must declare a parameter in here (doesn't matter which) or 
       # it'll not register the proxy ahead of time

       ProxySet disablereuse=off

       # Note: If you configure php-fpm to use the "pm = ondemand" 
       #then use "ProxySet disablereuse=on"
     </Proxy>

     <FilesMatch \.php$>
           SetHandler proxy:fcgi://php-fpm
     </FilesMatch>

    ErrorLog logs/example.com-error.log
    CustomLog logs/example.com-access.log combined
</VirtualHost>

Save the virtual host configuration file and reload Apache to apply changes.

sudo systemctl restart httpd

Step 5 – Enable Firewall Rules

Your server is ready to serve the application. If there is a firewall enabled on your system, make sure Apache ports are open to access from remote systems.

The following commands will open the required ports for you.

sudo firewall-cmd --zone=public --permanent --add-service=http
sudo firewall-cmd --zone=public --permanent --add-service=https
sudo firewall-cmd --reload

Step 6 – Test Setup

All done. To test the environment, create a PHP script with phpinfo() function. Place this file to your server document root. Use the below command to do this.

echo "<?php phpinfo(); ?>" > /var/www/html/info.php

Then access info.php using server IP address (for default VirtualHost) for your configured domain in Apache VirtualHost.

http://localhost/info.php

Conclusion

You have successfully configured an Apache with PHP-FPM on your CentOS 8 or RHEL 8 Linux system. You can now host a website from your server.

This tutorial will help you to change the default page in the .htaccess file. To do this first make sure you are using Apache web server and you have enabled .htaccess for the virtual host. Let’s edit the .htaccess file on your website document root and add a DirectoryIndex entry followed by file name. Now Apache will use this file as your default file.

#Default index page

DirectoryIndex home.html

You can also define more than one file like below. In this Apache will serve one of below file default file.

#Multiple default index page 

DirectoryIndex home.html index.html index.php index.htm
