1. 檢查是否有 check_ldap 檢查指令
一個是使用採用簡單認證，另外一個是支援加密傳輸
# locate check_ldap
/usr/lib64/nagios/plugins/check_ldap
/usr/lib64/nagios/plugins/check_ldaps
2. 檢查一下，check_ldap 須要加入的參數
# /usr/lib64/nagios/plugins/check_ldap -h
Options:
-h, –help
Print detailed help screen
-V, –version
Print version information
–extra-opts=[section][@file]
Read options from an ini file. See http://nagiosplugins.org/extra-opts

[@more@]3. 測試一下
# /usr/lib64/nagios/plugins/check_ldap -H ldap.test.ilc.edu.tw -b dc=ldap,dc=test.ilc.edu.tw -p 389
LDAP OK – 0.026 seconds response time|time=0.026050s;;;0.000000
4. 在 /etc/nagios/objects/commands.cfg 檔案加入
# ‘check_ldap’ command definition
define command{
command_name check_ldap
command_line $USER1$/check_ldap -H $HOSTADDRESS$ -b $ARG1$ -p $ARG2$
}
5. 在要偵測的 DNS 主機加入
# vim /etc/nagios/servers/ldap.cfg
define service{
use generic-service ; Name of service template to use
host_name ldap.test.ilc.edu.tw
service_description LDAP
check_command check_ldap!dc=ldap,dc=test.ilc.edu.tw!389
notifications_enabled 1
}
重新啟動 Nagios
# service nagios restart
Running configuration check…done.
Stopping nagios: .done.
Starting nagios: done.
如果沒有出現錯誤訊息，代表設定成功
