nagios功能不少，最主要是有报警功能，可是nagios也有一个缺点，就是自身没有图形化工具，要另外去装pnp4nagios,网上大部分都是结合apache的，下面说一下pnp4nagios配合nginx的配置php
一，安装pnp4nagioscss
[root@localhost objects]# yum install pnp4nagios rrdtool html
若是找不到包换epel源，博客里面有搜一下。关于nagios的安装，请参考：nagios 安装配置 详解linux
二，配置nagiosios
1，修改nagios.cfgnginx
[root@localhost objects]# vim /etc/nagios/nagios.cfg //修改如下内容 apache
process_performance_data=1 //由0改成1 vim
host_perfdata_command=process-host-perfdata //前面的注释拿掉 服务器
service_perfdata_command=process-service-perfdata //注释拿掉
enable_environment_macros=1 //若是有注释拿掉
2，修改commands.cfg
注释掉原有对process-host-perfdata和process-service-perfdata，从新定义
[root@localhost objects]# vim /etc/nagios/objects/commands.cfg
define command {
command_name process-service-perfdata
command_line /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl #根据实际路径
}
define command {
command_name process-host-perfdata
command_line /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl #根据实际路径
}
四、修改配置文件templates.cfg
添加如下内容
[root@localhost objects]# vim /etc/nagios/objects/templates.cfg
define host {
name hosts-pnp
register 0
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_
process_perf_data 1
}
define service {
name srv-pnp
register 0
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
process_perf_data 1
}
5，修改服务器配置文件localhost.cfg
[root@localhost objects]# vim /etc/nagios/objects/localhost.cfg
define host{
use linux-server,hosts-pnp
host_name localhost
alias localhost
address 127.0.0.1
}
define service{
use local-service,srv-pnp
host_name localhost
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}
上面只是例举了一个，你能够都加一下。
三，pnp4nagios配置
在网上好多关于pnp4nagios的文章，都是要把mv misccommands.cfg-sample misccommands.cfg 生成配置文件，我是yum安装的，安装目录下根本没有sample这样的东西
[root@localhost objects]# tree /etc/pnp4nagios/
/etc/pnp4nagios/
├── background.pdf
├── check_commands
│ ├── check_all_local_disks.cfg
│ ├── check_nrpe.cfg
│ └── check_nwstat.cfg
├── config.php
├── misccommands.cfg
├── nagios.cfg
├── npcd.cfg
├── pages
│ └── web_traffic.cfg
├── pnp4nagios_release
├── process_perfdata.cfg
└── rra.cfg
所在我根本没有配置任何东西。
四，重启nagios，启动npcd
[root@localhost pnp4nagios]# /etc/init.d/npcd start
[root@localhost pnp4nagios]# /etc/init.d/nagios restart
五，nginx配置
配置nginx的时候，配置挺头痛的，nagios的根目录是有php的，pnp4nagios是放在nagios的根目录下面，pnp4nagios也是php的，配置很差容易错乱的。
server
{
listen 80;
server_name nagios.xxxx.com;
index index.php;
root /usr/share/nagios/html;
location ~ .*\.(php|php5)?$ { //nagios根目录的php
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { //nagios的图片重写
rewrite ^/nagios/images/(.*) /images/$1 break;
rewrite ^/pnp4nagios/index.php/(.*) /pnp4nagios/$1 break;
expires 30d;
}
location ~ .*\.(js|css)?$ { //nagios的js,css重写
rewrite ^/nagios/stylesheets/(.*) /stylesheets/$1 break;
rewrite ^/nagios/js/(.*) /js/$1 break;
rewrite ^/pnp4nagios/index.php/(.*) /pnp4nagios/$1 break;
expires 1h;
}
location ~ .*\.cgi$ { //nagios的主程序是perl的，perl的cgi重写
root /usr/lib64/nagios/cgi-bin;
rewrite ^/nagios/cgi-bin/(.*)\.cgi /$1.cgi break;
fastcgi_pass 127.0.0.1:9001;
fastcgi_index index.cgi;
include fastcgi.conf;
}
location ~ ^(/pnp4nagios.*\.php)(.*)$ { //pnp4nagios的php重写
rewrite ^/pnp4nagios/index.php/index.php/(.*)$ /pnp4nagios/index.php/$1; break;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
在这里有一个问题就是http://nagios.xxxx.com/pnp4nagios/index.php/index.php/graph?host=localhost&srv=PING在这里有二个index.php，这个是php的程序加上去的，我并无改。同一个页面有二种连接。
由nagios的监控页面，跳转到pnp4nagios监控页面的链接是
http://nagios.xxxx.com/pnp4nagios/index.php/graph?host=localhost&srv=PING
点php4nagios监控页面中的链接而后就会多加一个index.php，
http://nagios.xxxx.com/pnp4nagios/index.php/index.php/graph?host=localhost&srv=PING
这也是上面我为何要加这一句rewrite ^/pnp4nagios/index.php/index.php/(.*)$ /pnp4nagios/index.php/$1; break;的缘由
看一下效果图
nagios 监控页面看到pnp4nagios图标，折线小图
