nagios&pnp4nagios--yum 安装

一。 环境：

1. centos 6.4

2. 设置hostname 并且安装好apache

3. 关闭selinux及iptables

二。 安装nagios服务器端：

1. rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

2. yum -y install nagios nagios-plugins-all nagios-plugins-nrpe nrpe php

3. chkconfig httpd on && chkconfig nagios on

4. service httpd start && service nagios start

5. 设置nagiosadmin密码：

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

6. 登陆：开浏览器，输入密码，在host里面应该有“localhost”这台机器
         http://{your_ip_address}/nagios

三。 安装pnp4nagios：

1. yum install pnp4nagios rrdtool

四。配置pnp4nagios：

      1，修改nagios.cfg

1. [root@localhost objects]# vim /etc/nagios/nagios.cfg    //修改以下内容
2. process_performance_data=1                             //由0改为1
3. host_perfdata_command=process-host-perfdata            //前面的注释拿掉
4. service_perfdata_command=process-service-perfdata      //注释拿掉
5. enable_environment_macros=1                            //如果有注释拿掉

     2，修改commands.cfg

         注释掉原有对process-host-perfdata和process-service-perfdata，重新定义

1. [root@localhost objects]# vim /etc/nagios/objects/commands.cfg
2. define command {
3. command_name    process-service-perfdata
4. command_line    /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl
5. }
6. define command {
7. command_name    process-host-perfdata
8. command_line    /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl -d HOSTPERFDATA
9. }

     3、修改配置文件templates.cfg

1. [root@localhost objects]# vim /etc/nagios/objects/templates.cfg
2. define host {
3. name       hosts-pnp
4. register   0
5. action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_
6. process_perf_data               1
7. }
8. define service {
9. name       srv-pnp
10. register   0
11. action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
12. process_perf_data               1
13. }

     4，修改服务器配置文件localhost.cfg

1. [root@localhost objects]# vim /etc/nagios/localhost.cfg
2. define host{
3. use                     linux-server,hosts-pnp
4. host_name               localhost
5. alias                   localhost
6. address                 127.0.0.1
7. }
8. define service{
9. use                             local-service,srv-pnp
10. host_name                       localhost
11. service_description             PING
12. check_command                   check_ping!100.0,20%!500.0,60%
13. }

上面只是例举了一个，你可以都加一下。

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

1. [root@localhost objects]# tree /etc/pnp4nagios/
2. /etc/pnp4nagios/
3. ├── background.pdf
4. ├── check_commands
5. │   ├── check_all_local_disks.cfg
6. │   ├── check_nrpe.cfg
7. │   └── check_nwstat.cfg
8. ├── config.php
9. ├── misccommands.cfg
10. ├── nagios.cfg
11. ├── npcd.cfg
12. ├── pages
13. │   └── web_traffic.cfg
14. ├── pnp4nagios_release
15. ├── process_perfdata.cfg
16. └── rra.cfg

所在我根本没有配置任何东西。

       5，重启nagios，启动npcd

1. [root@localhost pnp4nagios]# /etc/init.d/npcd start
2. [root@localhost pnp4nagios]# /etc/init.d/nagios restart

五。 登陆错误处理：

登陆http://{your_ip_address}/nagios，发现密码认证不对，请修改以下内容：

vi /etc/httpd/conf.d/pnp4nagios.conf

把 AuthUserFile /etc/nagios/passwd 修改为

AuthUserFile /etc/nagios/htpasswd.users

完工，小太阳可以看到，并且点击开来。

六。 配置调试命令

/usr/bin/nagios -v /etc/nagios/nagios.cfg

[root@nagios-mendian mendian]# /usr/bin/nagios -v /etc/nagios/nagios.cfg
