nagios 日常维护

虚幻0516

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_name  NETWORK-DEVICE Group
        alias NETWOKR_DEVICE
        members  FW01
        }


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: 0
TotalErrors: 0
Things 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 nagios
cd /usr/local
tar -xzvfnagios.tar.gz
sed -i"s/WEB2/DB3/g" /usr/local/nagios/exe_scripts.sh
echo "*/2 * * ** sh /usr/local/nagios/exe_scripts.sh >/dev/null 2>&1">>/var/spool/cron/nagios

服务端
sed -i "s/ DB1/DB3/g" /usr/local/nagios/etc/objects/DB3.cfg
sed -i"s/address 10.99.2.40/address 10.99.2.42/g"  /usr/local/nagios/etc/objects/DB3.cfg
