> nagios

What is the Monitoring engine log directory ?

> /usr/local/nagios/var

Where is your monitoring plugins (libexec) directory ?

default to [/usr/lib/nagios/plugins]

> /usr/local/nagios/libexec

What is the Monitoring engine init.d script ?

登入Centreon

http://192.168.249.130/centreon

頁面三-Monitoring engine information

Monitoring engine選擇nagios

Nagios directory設定/usr/local/nagios

Nagiostats binary設定/usr/local/nagios/bin/nagiostats

Nagios image directory設定/usr/local/nagios/share/images

頁面四-Broker module information

Broker Module選擇ndoutils

Ndomod binary (ndomod.o)設定/usr/local/nagios/bin/ndomod.o

頁面五-Admin information

設定管理員資料

頁面六-Database information

Database Host Address (default: localhost)設定192.168.249.130 或 localhost

輸入原先設定的MySQL密碼mysql

進行以下操作

[root@VM centreon-2.5.1]# /etc/init.d/centcore restart

[root@VM centreon-2.5.1]# /etc/init.d/centstorage restart

[root@VM centreon-2.5.1]# /etc/init.d/ndo2db restart

以上這個指令若不行，請輸入以下指令後，再輸入一次以上的指令

[root@VM centreon-2.5.1]# killall ndo2db

此時，點選Configuration --> Centreon --> Pollers就可以看到Process有啟動了。
