1. 安装配置Apache、PHP(忽略此次安装步骤)
2. 安装nagios
   rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

   (此步完成即可通过Web访问Nagios)
4. 安装PNPNagios

5. 修改 /etc/nagios/nagios.cfg
   process_performance_data=1                                          // 将0 修改为 1 
   host_perfdata_command=process-host-perfdata               // 取消注释
   service_perfdata_command=process-service-perfdata       // 取消注释

6. 修改 /etc/nagios/objects/commands.cfg

   

   # ‘process-host-perfdata‘ command definition  
   define command{  
       command_name    process-host-perfdata  
       command_line    /usr/libexec/pnp4nagios/process_perfdata.pl  -d HOSTPERFDATA  
       }  
      
      
   # ‘process-service-perfdata‘ command definition  
   define command{  
       command_name    process-service-perfdata  
       command_line    /usr/libexec/pnp4nagios/process_perfdata.pl 
       }  

   commands.cfg Code
7. 修改配置文件/etc/nagios/objects/templates.cfg, 添加以下内容
   
   

   define host {   
          name       hosts-pnp   
          register   0   
          action_url /pnp4nagios/graph?host=$HOSTNAME$  
          process_perf_data              1   
   }   
   define service {   
          name       srv-pnp   
          register   0   
          action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$   
          process_perf_data              1   
   }

   templates.cfg Code

8. 修改服务器配置文件/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%   
          } 

   localhost.cfg Code

9. 修改 /etc/nagios/cgi.cfg 里的用户名是无效的

   default_user_name=nagiosadmin

10. 重启nagios 和 apache
    chkcofing httpd on
    chkconfig nrpe on
    chkconfig npcd on
    chkconfig nagios on

11. 遇到的问题
    

    ping图片报错：
    cd /var/lib
    chown -R nagios.nagios php/
    原理:php是apache的组，而我的httpd.conf中将httpd的服务改成了nagios用户和组php权限改为nagios即可
