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

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

An ISO image (International Organization for Standardization) is an archive file (also known as a disc image) of an optical disc, composed of the data contents of every written sector of an optical disc, including the optical disc file system. ISO images can be created from optical discs, or can be used to recreate optical discs using software from many software vendors. ISO image files typically have a file extension of .iso. The name ISO is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image might also contain a UDF (ISO/IEC 13346) file system.

To mount an ISO image under Linux, you need simply to do the following steps.

Step 1. You must be logged in as root. If not root user then switch to root user using following command:

$ sudo -i

If you are using RedHat / CentOS / Fedora

$ su

Step 2. Create a mounpoint, example /mnt/iso

# mkdir -p /mnt/iso

Step 3. Use mount command as follows to mount iso file called image.iso

# mount -o loop image.iso /mnt/iso

Where,
-o: Options are specified with a -o flag followed by a comma separated string of options. Some of these options are only useful when they appear in the /etc/fstab file. (More)

loop: A loop device is a pseudo-device that makes a file accessible as a block device. Loop devices are often used for CD ISO images and floppy disc images. Mounting a file containing a filesystem via such a loop mount makes the files within that filesystem accessible. They appear in the mount point directory using above commands.
