一、服務端配置：

1. 安裝軟體：

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

2. 修改nagios主設定檔：vim /etc/nagios/nagios.cfg

   cfg_dir=/etc/nagios/conf.d  #確保其中有這行代碼

3. 修改cgi設定檔，添加使用者：vim /etc/nagios/cgi.cfg

   authorized_for_system_information=nagiosadmin,leeauthorized_for_configuration_information=nagiosadmin,leeauthorized_for_system_commands=nagiosadmin,leeauthorized_for_all_services=nagiosadmin,leeauthorized_for_all_hosts=nagiosadmin,leeauthorized_for_all_service_commands=nagiosadmin,leeauthorized_for_all_host_commands=nagiosadmin,lee

4. 修改命令設定檔command.cfg：vim /etc/nagios/objects/commands.cfg

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

5. 修改連絡人設定檔：vim /etc/nagios/objects/contacts.cfg

   define contact{    contact_name                    nagiosadmin     use             generic-contact         alias                           Nagios Admin            email                           [email protected]    }define contactgroup{    contactgroup_name       admins    alias                   Nagios Administrators    members                 nagiosadmin    }

6. 添加遠程主機的監控指令（可以用本地設定檔/etc/nagios/objects/localhost.cfg作為模板）：
   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    }#去掉這組定義#define hostgroup{#        hostgroup_name  linux-servers #        alias           Linux Servers #        members         lee     #        }define service{    use                             local-service             host_name                       lee    service_description             PINGcheck_command           check_ping!100.0,20%!500.0,60%    }define service{    use                             local-service             host_name                       lee    service_description             Root Partitioncheck_command           check_local_disk!20%!10%!/    }define service{    use                             local-service             host_name                       lee    service_description             Current Userscheck_command           check_local_users!20!50    }define service{    use                             local-service             host_name                       lee    service_description             Total Processescheck_command           check_local_procs!250!400!RSZDT    }define service{    use                             local-service             host_name                       lee    service_description             Current Loadcheck_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 Usagecheck_command           check_local_swap!20!10    }define service{    use                             local-service             host_name                       lee    service_description             SSHcheck_command           check_sshnotifications_enabled       0    }define service{    use                             local-service             host_name                       lee    service_description             HTTPcheck_command           check_httpnotifications_enabled       0    }

7. 檢查設定檔文法：

   nagios -v /etc/nagios/nagios.cfg

8. 修改nagios相關目錄許可權：

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

9. 設定apache賬戶密碼：

   htpasswd  -c  /etc/nagios/passwd  lee

10. 啟動服務：

    systemctl  start  httpdsystemctl  start  nagios

    二、用戶端配置：

11. 安裝軟體：

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

12. 修改 nrpe 主設定檔：vim /etc/nagios/nrpe.cfg

    #添加服務端ipallowed_hosts=127.0.0.1,192.168.8.81

13. 啟動nrpe服務：

    systemctl  start  nrpe

    三、測試：
