Nagios下ndo2db服務啓動腳本

在做Nagios實驗中，需要反覆通過命令重啓Nagios服務和Ndo2db服務，非常麻煩。所以寫了個Ndo2db啓動腳本，供參考！

# start開啓服務，stop停止服務，status查看服務狀態，restart重啓服務

# 實際操作
# 1、拷貝腳本到/etc/init.d下,vi ndo2db
# 2、添加腳本執行權限chmod +x ndo2db
# 3、啓動服務/etc/init.d/ndo2db start，停止服務/etc/init.d/ndo2db stop,查看服務/etc/init.d/ndo2db status,重啓服務/etc/init.d/ndo2db restart.
# 初次寫模塊化腳本，如果有問題，請指正，謝謝！
