Tomcat修改80埠，埠被佔用，System佔用80埠問題解決

今天有些小小需求要使用Tomcat，將Tomcat修改為80埠，修改之後啟動Tomcat，報錯，提示埠被佔用。下面來看看問題怎麼解決

1、修改Tomcat埠號

開啟Tomcat安裝目錄，看到如下目錄

修改之後，儲存，開啟Tomcat。報錯，錯誤如下

這就是說我們修改的80埠被佔用了。

因為我電腦上裝有IIS伺服器 ，他的預設埠是80，就想著把IIS伺服器停掉，開啟IIS伺服器找到最上面節點，右鍵停止

再次啟動Tomcat，發現還是不行，好吧，開啟伺服器管理，找到IIS Admin Service服務，停止掉

再次重啟Tomcat，還不行，今天上帝和耶穌打牌去了吧。。。。

好吧，開啟命令列輸入命令netstat -oan|find "80"

發現80埠被PID為4的哥們佔用，好吧接著找，在命令列輸入tasklist|find "4"

哎喲，我去被System佔用了，不會吧

接著找吧，在命令列輸入netsh http show servicestate

恍然大悟，原來是SQL服務，立馬的，幹掉他。

重啟Tomcat，在瀏覽器位址列輸入127.0.0.1 測試出現Tom貓OK，解決
