同一伺服器啟動多個tomcat服務，tomcat啟動後即停止

結論，由于同一個伺服器上啟動了多個tomcat服務，造成端口占用，故tomcat啟動失敗。隻需要把兩個tomcat沖突的端口修改成不一樣的端口即可。

修改conf/server.xml檔案裡面的設定的端口号

修改前

<!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8009" protocol="AJP/1.3" redirectPort="18443" />
           

修改後

<!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="18009" protocol="AJP/1.3" redirectPort="18443" />
           

檢視端口占用指令

netstat -alnp | grep 8125
           

示例

[[email protected] ~]# netstat -alnp | grep 8009
tcp        0      0 0.0.0.0:8009                0.0.0.0:*                   LISTEN      21153/java          
tcp        0      0 0.0.0.0:18009               0.0.0.0:*                   LISTEN      20849/java  
           

上面可以看出 兩個java程序 (pid 21153 和 pid 20849)目前分别占用了 8009 端口 和 18009 端口

強制殺死某個java程序

kill -9 21153
