-=== Configuring php-fpm ===
+~~NOCACHE~~
-When configuration php-fpm you are able to configure it using ports or sockets.
+====== php-fpm ======
-\\
+{{tabembed>[[php-fpm_centos6|CentOS 6 , [[php-fpm_centos7|CentOS 7}}
-The best thing to do is configure with socks as this avoids the networking stack associated with ports.
-\\
-This means that php-fpm will be using files (sockets) to run which could be considered slower because of potential slow HDDs however the files are mostly stored in RAM so it makes accessing them significantly quicker.
-^ Sockets ^  fastcgi_pass unix:/run/php-fpm/example.com.sock ^
-^ Ports   ^  fastcgi_pass 127.0.0.1:9000; ^
-\\
-\\
-=== Configuring php-fpm Pool ===
-To specify different server pools for each website you can create a website pool in the /etc/php-fpm.d/ directory.
-\\
-E.g /etc/php-fpm.d/lukeslinux.co.uk
-\\
-You would then want something similar to the following:
-<sxh bash>
-[lukeslinux.co.uk]
-listen = /run/php-fpm/lukeslinux.co.uk.sock
-listen.allowed_clients = 127.0.0.1
-user = nginx
-group = nginx
-pm = dynamic
-pm.max_children = 50
-pm.start_servers = 5
-pm.min_spare_servers = 5
-pm.max_spare_servers = 35
-slowlog = /var/log/php-fpm/lukeslinux.co.uk-slow.log
-php_admin_value[error_log] = /var/log/php-fpm/lukeslinux.co.uk-error.log
-php_admin_flag[log_errors] = on
-php_value[session.save_handler] = files
-php_value[session.save_path] = /var/lib/php/session
-</sxh>
-\\
-\\
-=== Troubleshooting ====
-If you are looking to view the processes, you will need to use different commands depending on how its been configured:
-^ Config ^ Command ^
-| socket | netstat -plnx | grep 'php-fpm' |
-| port   | netstat -plnt | grep 'php-fpm  |
-\\
-Example output of netstat -plnx:
-<sxh bash>
-unix 2 [ ACC ] STREAM LISTENING 146689 21372/php-fpm: mast /run/php-fpm/lukeslinux.co.uk.sock
-</sxh>
-\\
-\\
-=== Website Issues ===
-Make sure that php-fpm hasnt hit max processes;
-<sxh bash>
-grep "pm.max_spare_servers" /etc/php-fpm.d/www.conf
-</sxh>
-<sxh bash>
-ps -eo cmd,pid,pcpu --sort:-pcpu | grep -v grep | grep -c php-fpm
-</sxh>
