Add Redis Extension:

1. sudo rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
2. sudo yum --enablerepo=remi,remi-php56 install redis php-pecl-redis
   

Confirm addition of module:

1. php -m | grep redis
   

Configure php-fpm:

Edit php.ini and set the cgi.fix_pathinfo attribute to 0.

1. cgi.fix_pathinfo=0

Update the php-fpm config file (/etc/php-fpm.d/www.conf) to reflect the following values:

1. listen = /var/run/php-fpm/php-fpm.sock
2. listen.owner = nginx
3. listen.group = nginx
4. user = nginx
5. group = nginx

Change the permissions on the following files to Nginx:

1. sudo chown nginx:nginx /var/lib/php-fpm/session
2. sudo chown nginx:nginx /var/lib/php-fpm/wsdlcache
   

Restart php-fpm for changes to take effect:

1. sudo systemctl start php-fpm

Enable php-fpm to run on start:

1. sudo systmctl enable php-fpm

Configure Nginx to Process PHP:

Modify the Nginx config file (/etc/nginx/conf.d/default.conf) to:

• Add index.php options as first value of the index directive to allow PHP index files to be served when a directory is requested;
• Modify server_name directive to point to server's domain name or public ip address;
• Add error processing;
• Specify PHP processor and define a try_files directive to prevent bad requests from being passed on to the PHP processor.

1. server {
           listen  80;
           server_name     www.centos.dev centos.dev;
   
           root    /usr/share/nginx/html;
           index index.php index.html index.htm;
   
           location / {
                   try_files $uri $uri/ =404;
           }
   
           error_page 404 /404.html;
           error_page 500 502 503 504 /50x.html;
           location = /50x.html {
                   root /usr/share/nginx/html;
           }
   
           location ~ \.php$ {
                   try_files $uri =404;
                   fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
                   fastcgi_index index.php;
                   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                   include fastcgi_params;
           }
   }

Enable CURL calls by updating SELinux:

1. sudo setsebool -P httpd_can_network_connect 1
   

Add Redis port to SELinux:

1. sudo semanage port -a -t http_port_t -p tcp 6379

Check to confirm port exception:

1. sudo semanage port -l | egrep '(^http_port_t|6379)'
   

Disable Xdebug:

Find the extension ini file (/etc/php.d/15-xdebug.ini) and comment out the top line. Restart php-fpm (if using php-fpm.)
