linux下根據埠號查詢對應程式

我們經常使用netstat -lnp可以查詢對應埠跟程式，但是有些埠是在netstat -lnp裡卻沒顯示對應的程式pid，如果我們使用某個埠已經被佔用，需要找到對應占用埠的進

程關閉之類的，此時可以透過lsof來查詢對應埠的對應程式pid號，

[wei@vm-cbu-qa-168-13 web-deploy]$ netstat -lnp

will not be shown, you would have to be root to see it all.)

比如我們要查詢20880埠被那個程式佔用，netstat查詢不出來

[wei@vm-cbu-qa-168-13 web-deploy]$ netstat -lnp | grep 20880 (Not all processes could be identified, non-owned process info

lsof命令引數解釋

　　1) -P :這個選項約束著網路檔案的埠號到埠名稱的轉換。約束轉換可以使lsof執行得更快一些。在埠名稱的查詢不能奏效時，這是很有用的。

　　2) -n : 這個選項約束著網路檔案的埠號到主機名稱的轉換。約束轉換可以使lsof的執行更快一些。在主機名稱的查詢不能奏效時，它非常有用。

　　3) -l :這個選項約束著使用者ID號到登入名的轉換。在登入名的查詢不正確或很慢時，這個選項就很有用。

　　4) +M :此選項支援本地TCP和UDP埠對映程式的註冊報告。

　　5) -i4 :僅列示IPv4協議下的埠。

　　6) -i6 : 僅列示IPv6協議下的埠。
