一.建组建帐号 groupadd nagcmd useradd apache useradd nagios usermod -G nagcmd nagios usermod -G nagcmd apache 二、安装 nagios ./configure --with-command-group=nagcmd make all make install make install-init make install-commandmode make install-config 三.配置WEB接口 htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin 创建一个登录WEB的帐号 四.装nagios-plugin-1.4.13 cd nagios-plugins-1.4.15 ./configure --with-nagios-user=nagios --with-nagios-group=nagios make make install 五.将nagios加入服务并启动，同时启动apache chkconfig --add nagios chkconfig nagios on 验证nagios的安装 /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 如果出现下面的提示就OK了 ...... Total Warnings: 0 Total Errors: 0 Things look okay - No serious problems were detected during the pre-flight check 启动nagios和apache服务 service nagios start service httpd start 六.禁用selinux 我登录WEB页面好几次都无法通过验证，仔细看了一下说明发现是selinux的问题 setenforce 0 这么改完不需要重启系统就可生效，Getenforce可看到permissive。但一重启就又得来一次，我的CentOs上也没别的，直接disable吧 vi /etc/selinux/config SELINUX=disabled 现在可以用http://IP/nagios来登录了，用户名nagiosadmin 七.定义联系人和联系人组 vi /usr/local/nagios/etc/objects/contacts.cfg 配置 commands.cfg vi /usr/local/nagios/etc/objects/commands.cfg 在最后一行添加 #check nrpe define command { command_name check_nrpe command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ } 添加监控主机 vi /usr/local/nagios/etc/nagios.cfg 在 cfg_file=/usr/local/nagios/etc/objects/localhost.cfg 行后 增加 # Definitions for monitoring a linux machine cfg_file=/usr/local/nagios/etc/objects/linux.cfg 新建 linux.cfg 文件，并增加内容 vi /usr/local/nagios/etc/objects/linux.cfg 加入下面内容 define host{ use linux-server host_name nagiosTest alias nagiosTest address 192.168.8.209 } define service{ use generic-service host_name nagiosTest service_description check-swap check_command check_nrpe!check_swap } define service{ use generic-service host_name nagiosTest service_description check-load check_command check_nrpe!check_load } define service{ use generic-service host_name nagiosTest service_description check-disk check_command check_nrpe!check_disk } define service{ use generic-service host_name nagiosTest service_description zombie_procs check_command check_nrpe!check_zombie_procs } define service{ use generic-service host_name nagiosTest service_description check-users check_command check_nrpe!check_users } define service{ use generic-service host_name nagiosTest service_description total_procs check_command check_nrpe!check_total_procs } 重启nagios service nagios restart (责任编辑：IT) |
