FPM, FastCGI Process Manager is a PHP FastCGI implementation. Using php-fpm you can have a website running as its own user instead of a common user like Apache or www-data. In this post, we will go through the process of installing and configuring php-fpm with Nginx on CentOS 6.

php-fpm package is available in the official CentOS repository. There is no need to enable third party repositories in order to use php-fpm.

nginx package is available in Fedora EPEL repository.

Enable Fedora EPEL.

rpm -Uvh

Install nginx and php-fpm packages.

yum install nginx php-fpm

Create a user for our website.

useradd webuser1

As user webuser1, create the directory where we will have our PHP scripts.

mkdir  /home/webuser1/www/public -p

Also create the log directory.

mkdir /home/webuser1/logs

Let web server execute files in our home directory.

chmod o+x /home/webuser1/

Create the file /home/webuser1/www/public/index.php and write some sample PHP code in it.


Configure php-fpm. Craete the file /etc/php-fpm.d/webuser1.conf and add the below contents.

listen =
listen.allowed_clients =
user = webuser1
group = webuser1

pm = dynamic
pm.max_children = 15
pm.start_servers = 3
pm.min_spare_servers = 1
pm.max_spare_servers = 5
pm.max_requests = 2000

request_slowlog_timeout = 5
slowlog = /home/webuser1/logs/webuser1.slow.log

php_admin_value[error_log] = /home/webuser1/logs/webuser1.error.log
php_admin_flag[log_errors] = on

The FastCGI server runs on port 9001 and the IP address The process user and group should be webuser1. We also specify where to send the logs. Start php-fpm daemon.

/etc/init.d/php-fpm start

Configure Nginx. Within /etc/nginx/nginx.conf in the http block, add:

server_names_hash_bucket_size 64; Create the file, /etc/nginx/conf.d/webuser1.conf and append the following contents.

server {
    listen       80;

    root   /home/webuser1/www/public;
    index  index.html index.htm index.php;

    location ~ \.php$ {
      fastcgi_index  index.php;
      fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
      include        fastcgi_params;

Start Nginx.

/etc/init.d/nginx start

That is all you have to do to setup php-fpm and Nginx on CentOS 6.
