該文主要講述：如何配置php-fpm、常見報錯解決方法和php-fpm的啟動、關閉和重啟。

LNMP環境中的nginx是不支援php的，需要通過fastcgi外掛來處理有關php的請求。而php需要php-fpm這個元件提供該功能。在php5.3.3以前的版本php-fpm是以一個補丁包的形式存在的，而php5.3.3以後只需在編譯安裝時使用–enable-fpm載入該模組即可，無需另行安裝。

啟動php-fpm發現缺乏配置檔案/usr/local/php/etc/php-fpm.conf

此時只需複製php-fpm的配置檔案在安裝php時提供的配置檔案的模版/usr/local/php/etc/php-fpm.conf.default到相應目錄下即可，此處有兩種方法，均可提供配置檔案，即分別將末班複製到/usr/local/php/etc/或者 /usr/local/etc/並重命名為php-fpm.conf

①  

[[email protected] etc]# cd /usr/local/php/etc/

[[email protected] etc]# ls

pear.conf php-fpm.conf.default

[[email protected] etc]# cp/usr/local/php/etc/php-fpm.conf/usr/local/etc/php-fpm.conf

利用/usr/local/php/sbin/php-fpm啟動FPM

[[email protected] etc]# /usr/local/php/sbin/php-fpm

②  

[[email protected]

[[email protected] etc]# /usr/local/php/sbin/php-fpm

至此php-fpm配置完成，鑑於fpm是置於PHP和Nginx之間的一層應用，所以配置成服務開機自啟。

下面配置php-fpm以服務形式啟動

[[email protected] etc]# cd /usr/local/php-5.6.25/

[[email protected] php-5.6.25]# cp./sapi/fpm/init.d.php-fpm  /etc/init.d/php-fpm

[[email protected] php-5.6.25]# ll /etc/init.d/php-fpm

-rw-r--r-- 1 root root 2354 8月  3115:54 /etc/init.d/php-fpm

[[email protected] php-5.6.25]# chmod a+x/etc/init.d/php-fpm

[[email protected] php-5.6.25]# ll /etc/init.d/php-fpm

-rwxr-xr-x 1 root root 2354 8月  3115:54 /etc/init.d/php-fpm

[[email protected] php-5.6.25]# /etc/init.d/php-fpmstart

關閉php-fpm服務時發現報錯，缺乏pid檔案，解決方法為編輯配置檔案，啟用pid檔案

[[email protected] etc]# vim php-fpm.conf

pid = run/php-fpm.pid

[[email protected] etc]# kill -INT `cat/usr/local/php/var/run/php-fpm.pid`

cat: /usr/local/php/var/run/php-fpm.pid: 沒有那個檔案或目錄

[[email protected] etc]# /etc/init.d/php-fpm stop

Gracefully shutting down php-fpm warning,no pid file found - php-fpm is not running ?

嘗試關閉服務時再次報錯，手動建立php-fpm.pid檔案即可

[[email protected] etc]# cd /usr/local/php/var/run/

[[email protected] run]# vim php-fpm.pid

[[email protected] run]# ls

php-fpm.pid

[[email protected] run]# service php-fpm stop

Gracefully shutting down php-fpm . done

[[email protected] run]# service php-fpm start

Starting php-fpm done

[[email protected] run]# netstat -tunlp |grep 9000

tcp       0      0 127.0.0.1:9000              0.0.0.0:*                   LISTEN      3008/php-fpm       

[[email protected] run]# kill -INT `cat /usr/local/php/var/run/php-fpm.pid`

[[email protected] run]# netstat -tunlp |grep 9000

[[email protected] run]#  /etc/init.d/php-fpm start

Startingphp-fpm  done          

將服務新增到chkconfig列表，設定開機啟動

[[email protected] run]# chkconfig --add php-fpm

[[email protected] run]# chkconfig php-fpm on

至此，php-fpm配置完成，下面提供兩種控制方式

① PHP-FPM使用訊號控制：

INT, TERM 立刻終止

QUIT 平滑終止

USR1 重新開啟日誌檔案

USR2 平滑過載所有worker程序並重新載入配置和二進位制模組

啟動

[[email protected] run]# /usr/local/php/sbin/php-fpm

關閉：

[[email protected] run]# kill -INT `cat/usr/local/php/var/run/php-fpm.pid`

重啟：

[[email protected] run]# kill -USR2 `cat/usr/local/php/var/run/php-fpm.pid`

② 

服務方式控制

Usage: /etc/init.d/php-fpm{start|stop|force-quit|restart|reload|status}

[[email protected] run]# service php-fpm start

Starting php-fpm done

[[email protected] run]# service php-fpm stop

Gracefully shutting down php-fpm . done

[[email protected] run]#  /etc/init.d/php-fpm restart
