nagios 日常维护
1.nagios 启动（root身份）/etc/init.d/nagiosrestart（/etc/init.d/xinetdrestart 重启nsca,用于接收客户端的数据，端口为5667，接收数据出现问题时，需要重启）2.nagios 配置文件编辑（su -nagios编辑）1）/usr/local/nagios/etc/objects/hostgroups.cfg中定义hostgroup,有时禁用host,需要在这里把相应主机注释掉define hostgroup{ hostgroup_nameNETWORK-DEVICE Group alias NETWOKR_DEVICE membersFW01 }
2）/usr/local/nagios/etc/nagios.cfg（禁用主机注释掉相应主机配置文件）cfg_file=/usr/local/nagios/etc/objects/DB1.cfg
3.检查配置， /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 用来检查配置是否有问题，出现这样的说明没问题.........TotalWarnings: 0TotalErrors: 0Things lookokay - No serious problems were detected during the pre-flight check再用root重启/etc/init.d/nagiosrestart
常用脚本
客户端useradd -u 2001 -s/sbin/nologin nagioscd /usr/localtar -xzvfnagios.tar.gzsed -i"s/WEB2/DB3/g" /usr/local/nagios/exe_scripts.shecho "*/2 * * ** sh /usr/local/nagios/exe_scripts.sh >/dev/null 2>&1">>/var/spool/cron/nagios
