Install LEMP Server (Nginx, PHP 7.0, MariaDB & phpMyAdmin) on LinuxMint 17.1, 17.2, 17.3 & 18

4) PHP-FPM & PHP modules installation

Use the below command to install PHP-FPM & PHP modules. PHP initially called Personal Home Page, now it is called asHypertext Preprocessor. PHP is a open source software which was designed/developed for web development purpose. It is used for server-side scripting language as well as general-purpose programming language.

[Install php5 old systems]
$ sudo apt-get install php5 php5-fpm php5-mysql php5-cli php5-curl php5-gd php5-mcrypt php5-gettext php5-mbstring php5-common php5-xml

[Install php7]
$ sudo apt-get install php7.0 php7.0-fpm php7.0-mysql php7.0-mbstring php7.0-common php7.0-gd php7.0-mcrypt php-gettext php7.0-curl php7.0-cli php7.0-xml 

Configure PHP
We need to make few changes in php.ini file to work php-fpm properly. open php.ini file in your favorite text editor, and find cgi.fix_pathinfo= then uncomment, finally change the value from 1 to 0.

[For php5]
$ sudo nano /etc/php5/fpm/php.ini

[For php7]
$ sudo nano /etc/php/7.0/fpm/php.ini

cgi.fix_pathinfo=0                                                                        

By default PHP-FPM listens the socket on fpm.sock and its not effective one. So we need to change the settings in /etc/php5/fpm/pool.d/www.conf & /etc/php/7.0/fpm/pool.d/www.conf, from listen = /var/run/php5-fpm.sock & listen = /run/php/php7.0-fpm.sock to listen = 127.0.0.1:9000 to listen TCP. Just open the file www.conf and do it.

[For php5]
$ sudo nano /etc/php5/fpm/pool.d/www.conf
;listen = /var/run/php5-fpm.sock

[For php7]
$ sudo nano /etc/php/7.0/fpm/pool.d/www.conf
;listen = /run/php/php7.0-fpm.sock

listen = 127.0.0.1:9000

5) Nginx Configuration

Need to make lots of changes in Nginx default config file to make Nginx work properly.

Open /etc/nginx/nginx.conf file in your favorite text editor and change worker_processes values according to your CPU count. To identify CPU count use lscpu command. I have added 4 CPU’s because my system has 4 CPU. Make sure Nginx User should be www-data

$ nano /etc/nginx/nginx.conf

user www-data;
worker_processes 4;                                                                        

[ac-box color=”lred” icon=”fa-exclamation-triangle”]
1) When you are installing Nginx from Ubuntu Repository, it will create default conf file under /etc/nginx/sites-available/default
2) When you are installing Nginx from Nginx Repository, it will create default conf file under /etc/nginx/conf.d/default. So, don’t get confuse
3) Nginx Default Document Root : /usr/share/nginx/html but when you installing Nginx from distribution repository, web root location will be /var/www/html. It’s your wish to keep or change the location.
[/ac-box]

Open default Virtual host configuration file /etc/nginx/sites-available/default (I have installed Nginx from Ubuntu repository, that’s why my nginx file located in below location) in your favorite text editor and uncomment below lines. Also add/modify below colored lines.

I have removed all the unwanted lines from this file for clear explanation. Add your FQDN server.2daygeek.com instead of us.

$ sudo nano /etc/nginx/sites-available/default

[Web root location & port listening]
	server 
	{
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;
        root /usr/share/nginx/html;
        index index.php index.html index.htm;
        server_name server.2daygeek.com;

[Redirect server error pages to the static page]
        location / 
	{
	try_files $uri $uri/ /index.php;
        }
        error_page 404 /404.html;
        error_page 500 502 503 504 /50x.html;
        location = /50x.html 
	{
        root /usr/share/nginx/html;
        }
	
[Pass the PHP scripts to FastCGI server]
	location ~ \.php$ 
	{
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        try_files $uri =404;
        fastcgi_pass 127.0.0.1:9000;
	fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_index index.php;
        include fastcgi_params;
        }
	}                                                                    

6) Test PHP Configuration

Finally create a phpinfo.php file in web server root directory to test whether the php configuration is working or not.

$ sudo nano /usr/share/nginx/html/phpinfo.php

<?php
 phpinfo();
?>

Run nginx configuration test

$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Restart & Reload Necessary Services to take effect.

[Restart Nginx & php-fpm service on systemd Systems]
$ sudo systemctl reload nginx.service
$ sudo systemctl restart nginx.service

[php5 System]
$ sudo systemctl restart php5-fpm.service

[php7 system]
$ sudo systemctl restart php7.0-fpm.service

[Restart Nginx & php-fpm service on SysVinit Systems]
$ sudo service nginx reload
$ sudo service nginx restart
$ sudo service php5-fpm restart

Open your web browser and navigate to http://localhost/phpinfo.php or http://your-server-ip-address/phpinfo.php or http://127.0.0.1/phpinfo.php

7) Install phpMyAdmin

phpMyAdmin is a free, open-source web-based administration tool for managing the MySQL, MariaDB servers which will help us to manage the database easily.

$ sudo apt-get -y install phpmyadmin

Select the webserver to configure phpMyAdmin automatically. Nginx is not listed here, so don’t choose anything and simple press tab then hit ok.

Make sure your system should have database installed (MySQL, MariaDB, etc) before proceeding phpMyAdmin installation. Here choose Yes to configure database for phpmyadmin with dbconfig-common.

Enter the password for phpmyadmin database.

Re-enter the password for phpmyadmin database.

Just create symlink from /usr/share/phpmyadmin to /usr/share/nginx/html this will do the trick

[Create Symlink]
ln -s /usr/share/phpmyadmin /usr/share/nginx/html

[Restart Nginx service]
$ sudo systemctl restart nginx.service    [For Systemd Systems]
$ sudo service nginx restart    	  [For Systemd Systems]

Open your web browser and navigate to http://localhost/phpmyadmin or http://your-server-ip-address/phpmyadmin or http://127.0.0.1/phpmyadmin

Enter the UserName phpmyadmin and password which you set.
