How To Install Nginx And PHP-FPM On CentOS 6 Via Yum

In the last article, I showed you how to install Nginx and PHP (PHP-FPM) on CentOS 6 from source. Today, I’m going to show you how to install Nginx with PHP-FPM via yum.

Before starting to install Nginx and PHP-FPM, you must uninstall all previous Apache and PHP related RPMs installed on your system. Login as root and type the following command

# yum remove httpd* php*

Enabling Additional Repositories

By default, php-fpm is not available from the official CentOS repositories, but from the Remi RPM repository which itself depends on the EPEL repository; we can enable both repositories as follows:

# yum install yum-priorities -y
# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

Sample outputs

If you want to run php-fpm by default when the system boots, type the following command

# chkconfig --level 345 php-fpm on

PHP was installed with only core modules. It’s very likely that additional modules will be desired, such as MySQL, XML, GD, etc. Type the following command

# yum --enablerepo=remi install php-gd php-mysql php-mbstring php-xml php-mcrypt

To start PHP-FPM for the first time, type the following command

# /etc/init.d/php-fpm restart

Sample output

Starting php-fpm:                                          [ OK ]

Configure PHP-FPM and Nginx working together

The configuration file for Nginx is located at /etc/nginx/nginx.conf. To edit nginx.conf type the following command

# vi /etc/nginx/nginx.conf

Uncomment and edit as follows

        ...
	location / {
            root   /usr/share/nginx/html;
            index  index.html index.htm index.php;
        }
        ...
	location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }
        ...

Restart Nginx to reload new configuration, enter

# /etc/init.d/nginx reload

Now create the following PHP file in the document root

# vi /usr/share/nginx/html/info.php

Append content as follows:

<?php
phpinfo();
?>

Access it http://YOUR-SERVER-IP

Nginx Virtual Hosting Configuration

Your sample setup
IP: 192.168.1.113
Domain: domain.local
Hosted at: /home/www/domain.local

Type the following command to create user called www

# useradd www

Create necessary directories

# mkdir -p /home/www/domain.local/public_html
# mkdir -p /home/www/domain.local/log
# chown -R www.www /home/www/
# chmod 755 /home/www/

Creating virtual host config file

# cd /etc/nginx/conf.d/
# cp virtual.conf www.conf

Open www.conf, enter

# vi /etc/nginx/conf.d/www.conf

Append configuration as follows:

server {
        server_name  domain.local;
        root /home/www/domain.local/public_html;
        access_log /home/www/domain.local/log/domain.local-access.log;
        error_log /home/www/domain.local/log/domain.local-error.log;

        location / {
                index  index.html index.htm index.php;
        }
        location ~ \.php$ {
                include /etc/nginx/fastcgi_params;
                fastcgi_pass  127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }
}

You can also check the current status as well as the configuration syntax:

# /etc/init.d/nginx configtest

Sample outputs

the configuration file /etc/nginx/nginx.conf syntax is ok
configuration file /etc/nginx/nginx.conf test is successful

Now edit /etc/php-fpm.d/www.conf to change the users who own the php-fpm processes to www, enter

# vi /etc/php-fpm.d/www.conf

Find “group of processes” and edit as follows:

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = www
; RPM: Keep a group allowed to write in log dir.
group = www

Finally restart nginx

# /etc/init.d/nginx restart
# /etc/init.d/php-fpm restart
