标签：ali   检查   oca   roc   用户   efi   chmod   check   objects   

1. 安装软件：

   yum  -y  install  nagios  nagios-plugins  nagios-plugins-all  nagios-plugins-nrpe  nrpe

2. 修改nagios主配置文件：vim /etc/nagios/nagios.cfg

   cfg_dir=/etc/nagios/conf.d  #确保其中有这行代码

   

3. 修改cgi配置文件，添加用户：vim /etc/nagios/cgi.cfg

   authorized_for_system_information=nagiosadmin,lee
   authorized_for_configuration_information=nagiosadmin,lee
   authorized_for_system_commands=nagiosadmin,lee
   authorized_for_all_services=nagiosadmin,lee
   authorized_for_all_hosts=nagiosadmin,lee
   authorized_for_all_service_commands=nagiosadmin,lee
   authorized_for_all_host_commands=nagiosadmin,lee

   

4. 修改命令配置文件command.cfg：vim /etc/nagios/objects/commands.cfg

   #添加
   define command{
   command_name  check_nrpe
   command_line  $USER1/check_nrpe  -H  $HOSTADDRESS  -c  $ARG1
   }

   

5. 修改联系人配置文件：vim /etc/nagios/objects/contacts.cfg

   define contact{
       contact_name                    nagiosadmin     
   use             generic-contact     
       alias                           Nagios Admin        
       email                           complet@163.com
       }
   define contactgroup{
       contactgroup_name       admins
       alias                   Nagios Administrators
       members                 nagiosadmin
       }

6. 添加远程主机的监控指令（可以用本地配置文件/etc/nagios/objects/localhost.cfg作为模板）：
   cp -arf /etc/nagios/objects/localhost.cfg /etc/nagios/conf.d/lee.cfg
   vim /etc/nagios/conf.d/lee.cfg

   define host{
       use                     linux-server            
       host_name               lee
       alias                   lee
       address                 192.168.8.82
       }
   #去掉这组定义
   #define hostgroup{
   #        hostgroup_name  linux-servers 
   #        alias           Linux Servers 
   #        members         lee     
   #        }
   define service{
       use                             local-service         
       host_name                       lee
       service_description             PING
   check_command           check_ping!100.0,20%!500.0,60%
       }
   define service{
       use                             local-service         
       host_name                       lee
       service_description             Root Partition
   check_command           check_local_disk!20%!10%!/
       }
   define service{
       use                             local-service         
       host_name                       lee
       service_description             Current Users
   check_command           check_local_users!20!50
       }
   define service{
       use                             local-service         
       host_name                       lee
       service_description             Total Processes
   check_command           check_local_procs!250!400!RSZDT
       }
   define service{
       use                             local-service         
       host_name                       lee
       service_description             Current Load
   check_command           check_local_load!5.0,4.0,3.0!10.0,6.0,4.0
       }
   define service{
       use                             local-service         
       host_name                       lee
       service_description             Swap Usage
   check_command           check_local_swap!20!10
       }
   define service{
       use                             local-service         
       host_name                       lee
       service_description             SSH
   check_command           check_ssh
   notifications_enabled       0
       }
   define service{
       use                             local-service         
       host_name                       lee
       service_description             HTTP
   check_command           check_http
   notifications_enabled       0
       }

7. 检查配置文件语法：

   nagios -v /etc/nagios/nagios.cfg

8. 修改nagios相关目录权限：

   chown  nagios.nagios  /etc/logrotate.d/nagios
   chmod  g+w  /etc/logrotate.d/nagios
   chown  -R  nagios.nagios  /etc/nagios

9. 设置apache账户密码：

   htpasswd  -c  /etc/nagios/passwd  lee

10. 启动服务：

    systemctl  start  httpd
    systemctl  start  nagios

    二、客户端配置：

11. 安装软件：

    yum  -y  install  nagios-plugins  nagios-plugins-nrpe  nrpe

12. 修改 nrpe 主配置文件：vim /etc/nagios/nrpe.cfg

    #添加服务端ip
    allowed_hosts=127.0.0.1,192.168.8.81

    

13. 启动nrpe服务：

    systemctl  start  nrpe

    三、测试：
