shell 實戰 -- 基於一個服務啓動，關閉，狀態檢查的腳本

功能說明：

• check：檢查服務狀態，在開啓，關閉，狀態檢查時都會用到這個函數，因此封裝起來放到最前面
• start：開啓服務
• stop：關閉服務
• fstop：強制關閉
• status：檢查服務狀態
• running：查看全部正在運行的狀態

 

使用說明：

開啓服務：

啓動一個進程監聽 9000（默認）端口：

• sh standard_server.sh start

 

啓動一個進程監聽 8000（自定義）端口：

• 格式: sh standard_server.sh start ipaddress port
• sh standard_server.sh start 10.10.4.200 8000

關閉服務：

關閉監聽 9000（默認）端口：

• sh standard_server.sh stop

 

關閉監聽 8000（自定義）端口：

• 格式: sh standard_server.sh stop ipaddress port
• sh standard_server.sh stop 10.10.4.200 8000

查看監聽狀態：

查看 9000 端口（默認）監聽狀態：

• sh standard_server.sh status

 

查看 8000端口（自定義）監聽狀態：

• 格式: sh standard_server.sh status ipaddress port
• sh standard_server.sh status 10.10.4.200 8000

 

查看全部正在監聽端口：

• sh standard_server.sh running

 

代碼部分：
