nginx的性能远远优于apache，但由于nagios的web界面中包含php和c-cgi程序，因此需要两套fcgi管理工具（并非必须）和两套解释器（必须）。php用php-cgi跑就可以，c-cgi我选用fcgiwrap。下面介绍安装/配置步骤。
环境介绍：
先前环境：apache+php+nagios 除了nagios 其余的都使用yum自动安装
目标环境：nginx+php5.2.10(php-fpm patch)+nagios 均为源码编译安装
php-fpm：是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi
Spawn-fcgi：是lighttpd的一个分支项目，是一个cgi进程的管理器
● php 打php-fpm补丁，编译时启用--enable-fastcgi --enable-fpm 参数，使用php-fpm管理php-cgi。php安装详细步骤参见 张宴文章：http://blog.s135.com/nginx_php_v5/
● c-cgi 使用 Spawn-fcgi 管理 ，利用fcgiwrap驱动。fcgiwrap 介绍参见 http://nginx.localdomain.pl/wiki/FcgiWrap
php-cgi 监听 127.0.0.1:9000
fcgiwrap 监听 127.0.0.1:10000
nagios 安装配置不是本文重点，略过。web 目录如下：
/usr/local/nagios/share
安装配置
yum install fcgi fcgi-devel -y
php-fpm 的配置与运行这里略过，下面主要讲解Spawn-fcgi+fcgiwrap 的安装与配置
spawn-fcgi
# wget http://www.lighttpd.net/download/spawn-fcgi-1.6.2.tar.gz
# tar -xvzf spawn-fcgi-1.6.2.tar.gz
# cd spawn-fcgi-1.6.2/
# ./configure
# make
# cp src/spawn-fcgi /usr/local/bin/
fcgiwrap
# wget http://github.com/gnosek/fcgiwrap/tarball/master
# tar -xvzf gnosek-fcgiwrap-28ac6f9aa5e7dadf9aaf2062ab003a0fb4c82ad8.tar.gz
# cd gnosek-fcgiwrap-28ac6f9aa5e7dadf9aaf2062ab003a0fb4c82ad8/
# make
# mv fcgiwrap /usr/local/bin/
创建一个shell脚本来用spawn-fcgi 启动fcgiwrap实例
# vi /usr/local/bin/c-fcgi.sh
#!/bin/sh
/usr/local/bin/spawn-fcgi -f /usr/local/bin/fcgiwrap -a 127.0.0.1 -p 10000 -F 3 -P /var/run/fastcgi-c.pid -u www -g www
# chmod +x /usr/local/bin/c-fcgi.sh
创建一个系统启动进程，方便使用service 和chkconfig 命令管理
# vi /etc/init.d/c-fcgi
#!/bin/bash
# c-fcgi - this script starts and stops the fcgiwrap instance
#
# chkconfig: - 96 28
# description: c-fcgi
# processname: c-fcgi
C_SCRIPT=/usr/local/bin/c-fcgi.sh
RETVAL=0
case "$1" in
start)
echo "Starting fastcgi"
$C_SCRIPT
RETVAL=$?
;;
stop)
echo "Stopping fastcgi"
killall -9 fcgiwrap
RETVAL=$?
;;
restart)
echo "Restarting fastcgi"
killall -9 fcgiwrap
$C_SCRIPT
RETVAL=$?
;;
*)
echo "Usage: c-fastcgi {start|stop|restart}"
exit 1
;;
esac
exit $RETVAL
# <span style="color: #0000ff;">chkconfig --add c-fcgi</span>
# <span style="color: #0000ff;">chkconfig c-fcgi on</span>
# <span style="color: #0000ff;">service c-fcgi start</span>
验证启动,是否提供了相应的端口
# netstat -tulnp

通过将近2周的了解，个人认为munin属于轻量级的性能展示工具，相对于cacti其部署、展示、添加编辑插件都很简洁，如果拿来主义使用 Munin Exchange 提供的插件建立自己的监控项目那就更简单了。按照Munin官方的介绍，其最初是用来对网络进行监控，目前Munin Exchange 的插件库已经扩展到各个服务领域，通过官方的文档也很方便的写自己的插件。先来看一下安装后默认几个监控图：
