调试：
logrotate -d /usr/local/nginx/conf/logrotate.conf

执行：
logrotate -f /usr/local/nginx/conf/logrotate.conf

定期执行：
vi /etc/crontab
59 23 * * * root logrotate -f /usr/local/nginx/conf/logrotate.conf

创建 nagios 用户和组：
groupadd nagios
useradd -g nagios -d /usr/local/nagios -s /bin/bash nagios

创建一个 nagcmd 组用于从 Web 接口执行外部命令，并将 nagios 用户和 Web 用户都加到这个组中：
groupadd nagcmd
usermod -G nagcmd nagios
usermod -G nagcmd www-data

安装 Nagios:
apt-get install libgd2-xpm-dev
The following NEW packages will be installed:
defoma fontconfig-config libfontconfig1 libfreetype6 libgd2-xpm libjpeg62 libxpm4 ttf-dejavu ttf-dejavu-core ttf-dejavu-extra

tar zxvf nagios-3.2.0.tar.gz
cd nagios-3.2.0
./configure \
--prefix=/usr/local/nagios \
--with-command-group=nagcmd

make all

make install
make install-init
make install-config
make install-commandmode

配置 Nginx 支持 CGI ，然后在 Nginx 添加 Nagios 的配置如下：

server {
listen 80;
server_name nagios.domain.com;
root /usr/local/nagios/share;
index index.php index.html;
location ~ .*\.php?$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ .*\.cgi$ {
rewrite ^/nagios/cgi-bin/(.*)\.cgi /$1.cgi break;
fastcgi_pass 127.0.0.1:8999;
fastcgi_param SCRIPT_FILENAME /usr/local/nagios/sbin$fastcgi_script_name;
include fastcgi_params;
auth_basic "Nagios Access";
auth_basic_user_file /usr/local/nagios/etc/htpasswd.users;
}
location /nagios {
alias /usr/local/nagios/share;
}
location / {
auth_basic "Nagios Access";
auth_basic_user_file /usr/local/nagios/etc/htpasswd.users;
}
}

创建 Nagios Web 接口登录的用户：
apt-get install apache2-utils
The following NEW packages will be installed:
apache2-utils libapr1 libaprutil1 libldap-2.4-2 libpq5 libsqlite3-0

htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

重启 Nginx:
/etc/init.d/nginx restart

安装 Nagios 插件：
wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.13.tar.gz
tar zxvf nagios-plugins-1.4.13.tar.gz
cd nagios-plugins-1.4.13
./configure \
--prefix=/usr/local/nagios \
--with-nagios-group=nagcmd

make
make install

添加 nagios 服务：
sysv-rc-conf

检查配置文件是否有错误：
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

cgi 的权限验证问题：
vi /usr/local/nagios/etc/cgi.cfg
use_authentication=0

启动：
/etc/init.d/nagios start

打开 http://nagios.domain.com 输入之前设置的用户名和密码就可以查看 nagios 的页面了。不过此时还只能看到 localhost 的状态。

用 perl 写一个 daemon 程序来处理 cgi 文件：

vi /usr/local/bin/cgiwrap-fcgi.pl
#!/usr/bin/perl -w
use FCGI;
use Socket;

注意文件中的这两行：
#$socket = FCGI::OpenSocket( "127.0.0.1:8999", 10 );
#$socket = FCGI::OpenSocket( "/var/run/nginx/perl_cgi-dispatch.sock", 10 );
这两行都表示监听来自 perl CGI 的请求。
其中 perl_cgi-dispatch.sock 表示使用 unix socket 响应 CGI 请求。
127.0.0.1:8999 表示使用 TCP/IP 协议响应请求。
需要使用哪种方式就在下面的 FCGI::OpenSocket 中填入相对应的内容。

启动：
chmod +x /usr/local/bin/cgiwrap-fcgi.pl
/usr/local/bin/cgiwrap-fcgi.pl > /dev/null 2>&1 &

配置 Nginx 的 location 处理 cgi 文件：
location ~ .*\.cgi$ {
fastcgi_pass 127.0.0.1:8999;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

测试：
在 web 的根目录下创建一个 cgi 文件：
vi test.cgi
#!/usr/bin/perl
print "Content-type: text/html\n\n";
print "Hello, world.";

文件需要有可执行权限：
chmod +x test.cgi

访问 http://www.domain.com/test.cgi 看看有没有输出。

cgiwrap-fcgi.pl 随 nginx 一起启动/关闭：
修改 nginx 启动脚本：
在 start 段加入：
/usr/local/bin/cgiwrap-fcgi.pl > /dev/null 2>&1 &

在 stop 段加入：
PID=`/bin/netstat -npl | grep "127.0.0.1:8999" | awk '{print $7}' | cut -d "/" -f 1`
while [ -n "$PID" ]
do
kill -9 "$PID"
PID=`/bin/netstat -npl | grep "127.0.0.1:8999" | awk '{print $7}' | cut -d "/" -f 1`
done

tmpfs /tmpfs tmpfs size=256m,mode=1777 0 0

mount -a

创建相关目录
vi /usr/local/sbin/mkdir.sh

#/bin/sh

mkdir /tmpfs/nginx
chown -R nobody:nobody /tmpfs/nginx
chmod -R 1777 /tmpfs/nginx

mkdir /tmpfs/eaccelerator
chown -R nobody:nobody /tmpfs/eaccelerator
chmod -R 1777 /tmpfs/eaccelerator

I="0 1 2 3 4 5 6 7 8 9 a b c d e f"
for acm in $I;
do
for x in $I;
do
mkdir -p /tmpfs/phpsession/$acm/$x;
done;
done
chown -R nobody:nobody /tmpfs/phpsession
chmod -R 1777 /tmpfs/phpsession

chmod +x /usr/local/sbin/mkdir.sh
mkdir.sh

启动 PHP 和 Nginx
/usr/local/php-fcgi/bin/spawn-fcgi -a 127.0.0.1 -p 10080 -C 32 -u nobody -g nobody -f /usr/local/php-fcgi/bin/php
监听在 127.0.0.1 的 10080 端口并开启 32 个进程，使用和 Nginx 一样的 nobody 用户。（PHP5 的执行程序是 php-cgi）
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
重启 PHP 进程可以先 killall php 再启动。
重启 Nginx
kill -HUP `cat /var/run/nginx.pid`

清除超过一小时没有被访问到的 eAccelerator 缓存文件和创建时间超过一小时的 php session 文件，防止占满空间。
vi /etc/crontab
0 * * * * root find /tmpfs/eaccelerator -type f -amin +60 -exec rm {} \;
0 * * * * root find /tmpfs/phpsession -type f -cmin +60 -exec rm {} \;

配置开机自启动
vi /etc/rc.local
/usr/local/sbin/mkdir.sh
/usr/local/php-fcgi/bin/spawn-fcgi -a 127.0.0.1 -p 10080 -C 32 -u nobody -g nobody -f /usr/local/php-fcgi/bin/php
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

方便重启 Nginx
vi ~/.bashrc
alias nginx='kill -HUP `cat /var/run/nginx.pid`'

source ~/.bashrc
