munin 监控 php-fpm

php5.3以前php-fpm和php-cgi是分开的，php-fpm做为php-cgi,第三方的管理工具包存在的，php5.3以后，php吸收了php-fpm，当你查看进程时，在也看不到php-cgi了，取尔代之的是php-fpm进程。了解php-fpm进程的相关情况就很有必要了。

1,修改php-fpm配置

# vim /etc/php-fpm.d/www.conf

pm.status_path = /status     //把前面注释去掉

# /etc/init.d/php-fpm restart   //重启

2,修改nginx配置

# vim /etc/nginx/conf.d/munin.conf   //添加以下内容

location ~ ^/(status|ping)$ {
 include fastcgi_params;
 fastcgi_pass 127.0.0.1:9000;
 fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
 allow 127.0.0.1;
 #allow 192.168.1.101;
 #allow munin.51yip.com;
 deny all;
}

# /etc/init.d/nginx restart  //重启

访问http://xxxxx.com/status，如果出现以下内容，说明nginx和php-fpm配置对了

pool:                 www
process manager:      dynamic
start time:           14/Jan/2015:09:26:23 +0800
start since:          28796
accepted conn:        261
listen queue:         0
max listen queue:     0
listen queue len:     128
idle processes:       6
active processes:     1
total processes:      7
max active processes: 4
max children reached: 0

3,下载munin的php-fpm插件

https://github.com/tjstein/php5-fpm-munin-plugins

4,配置munin php-fpm插件

# unzip php5-fpm-munin-plugins-master.zip
# cd php5-fpm-munin-plugins-master
# chmod +x phpfpm_*
# ln -s /路径/phpfpm_* /etc/munin/plugins/

# vim /etc/munin/plugin-conf.d/php-fpm //创建新文件
[phpfpm*]
user tank
env.url http://munin.com/status
env.ports 80
env.phpbin php-fpm
env.phppool www

# /etc/init.d/munin-node restart  //重启

这里要注意[phpfpm*]可不是随便写的，根这个正则去找插件的，如果不匹配的话，在运行munin-run phpfpm_status 的时候，会报以下错误

Can't exec "/etc/munin/plugins/phpfpm_status": Permission denied

5,查看php-fpm插件是不是安装好了

[root@node1 plugins]# munin-run phpfpm_memory
ram.value 277811200

[root@node1 plugins]# munin-run phpfpm_status
idle.value 6
active.value 1
total.value 7

[root@node1 plugins]# munin-run phpfpm_processes
php_processes.value 7

[root@node1 plugins]# munin-run phpfpm_connections
accepted.value 406
