FastCGI 进程管理器 (FPM)

Table of Contents

FPM (FastCGI 进程管理器) 用于替换PHP FastCGI的大部分附加功能,对于高负载网站是非常有用的。


  • 支持平滑停止/启动的高级进程管理功能;

  • 可以工作于不同的uid/gid/chroot环境下,并监听不同的端口和使用不同的php.ini配置文件(可取代safe_mode的设置);

  • stdout 和 stderr 日志记录;

  • 在发生意外情况的时候能够重新启动并缓存被破坏的opcode;

  • 文件上传优化支持;

  • "慢日志" - 记录脚本 (不仅记录文件名,还记录PHP backtrace信息,可以使用ptrace或者类似工具读取和分析远程进程的运行数据) 运行所导致的异常缓慢;

  • fastcgi_finish_request() - 特殊功能:用于在请求完成和刷新数据后,继续在后台执行耗时的工作 (录入视频转换、统计处理等);

  • 动态/静态子进程产生;

  • 基本SAPI运行状态信息 (类似Apache的 mod_status);

  • 基于php.ini的配置文件.

the fpm process supports the USER2 signal, which is used to reload the config file.

kill -USR2 [pid]

should do the trick.

Init script setup

You will probably want to create an init script for your new php-fpm. Fortunately, PHP 5.3.3 provides one for you, which you should copy to your init directory and change permissions:

$ cp <php-5.3.3-source-dir>/sapi/fpm/ /etc/init.d/php-fpm
$ chmod 755 /etc/init.d/php-fpm

It requires a certain amount of setup. First of all, make sure your php-fpm.conf file is set up to  create a PID file when php-fpm starts. E.g.:
pid = /var/run/
(also make sure your php-fpm user has permission to create this file).

Now open up your new init script (/etc/init.d/php-fpm) and set the variables at the top to their relevant values. E.g.:

Your init script is now ready. You should now be able to start, stop and reload php-fpm:

$ /etc/init.d/php-fpm start
$ /etc/init.d/php-fpm stop
$ /etc/init.d/php-fpm reload

The one remaining thing you may wish to do is to add your new php-fpm init script to system start-up. E.g. in CentOS:

$ /sbin/chkconfig php-fpm on


Disclaimer: Although I did just do this on my own server about 20 mins ago, everything I've written here is off the top of my head, so it may not be 100% correct. Also, allow for differences in system setup. Some understanding of what you are doing is assumed.
