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
- [root@localhost objects]# vim /etc/nagios/nagios.cfg //修改以下内容
- process_performance_data=1 //由0改为1
- host_perfdata_command=process-host-perfdata //前面的注释拿掉
- service_perfdata_command=process-service-perfdata //注释拿掉
- 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
- [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
- }
- define command {
- command_name process-host-perfdata
- command_line /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl -d HOSTPERFDATA
- }
3、修改配置文件templates.cfg
- [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
- }
4，修改服务器配置文件localhost.cfg
- [root@localhost objects]# vim /etc/nagios/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
- [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。
5，重启nagios，启动npcd
- [root@localhost pnp4nagios]# /etc/init.d/npcd start
- [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
