nagios新增监控集群、卸载监控集群批量操作

标签：

1.一定要找应用侧确认每台节点上需要监控的进程，不要盲目以为所有hadoop集群的zk、journal啥的都一样，切记！

2.被监控节点只需要安装nagios-plugin和nrpe，依赖需要安装xinetd

3.确认被监控节点上没有安装过nagios

4.确认被监控节点间、被监控节点和nagios server间的互信

5.开始

5-1 选择一个同操作系统的集群a的一个节点an，目标集群b

ssh an

for dn in cluster{an..b1}

do

echo "$dn is configuring the nagios............................."

ssh $dn useradd nagios -d /usr/local/nagios

scp -r /usr/local/nagios/ root@$dn:/usr/local/

scp /etc/xinetd.d/nrpe  root@$dn:/etc/xinetd.d/nrpe

ssh $dn ‘echo "nrpe            5666/tcp                #nrpe" >>/etc/services‘

ssh $dn ‘chown -R nagios:nagios /usr/local/nagios/‘

ssh $dn ‘service xinetd restart‘

echo "$dn is end configuring  the nagios........................"

done

5-2 在集群b上批量安装

ssh b1

for dn in cluster{b2..bn}

do

echo "$dn is configuring the nagios............................."

ssh $dn useradd nagios -d /usr/local/nagios

scp -r /usr/local/nagios/ root@$dn:/usr/local/

scp /etc/xinetd.d/nrpe  root@$dn:/etc/xinetd.d/nrpe

ssh $dn ‘echo "nrpe            5666/tcp                #nrpe" >>/etc/services‘

ssh $dn ‘chown -R nagios:nagios /usr/local/nagios/‘

ssh $dn ‘service xinetd restart‘

echo "$dn is end configuring  the nagios........................"

done

5-3 如果配置了logcheck /var/log/messages,一定要确认下/var/log/messages的权限是不是705

5-4 在server端增加新集群的配置文件

mkdir -p /usr/local/nagios/etc/servers/b

cd /usr/local/nagios/etc/servers/a

cat an.cfg|sed ‘s/an/bn/g‘|sed ‘s/an_ip/bn_ip/g‘>/usr/local/nagios/etc/servers/b/bn.cfg

5-5 在server端增加新集群的组配置文件

vi /usr/local/nagios/etc/servers/group.cfg

define hostgroup{

          hostgroup_name b

          alias b

          members b1,....bn

}

6.集群下线

   这次只是在nagios前台下线，下线集群保留nagios软件，升级后再重新监控

   只需要在server端把该集群的所有配置删掉（移走）即可

   注：不要想着修改权限。。。。。修改权限的结果就是nagios起不起来。。。
