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

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
