Linux启动Tomcat失败解决方法Failed to initialize component [Connector[AJP/1.3-8019]]

1、先贴上错误日志

2、去Linux中找一下这个冲突的端口号

查看端口号对应的进程：lsof -i:8019 

注意：这里的8019是你自己报错信息的端口号(Connector[AJP/1.3-8019)

果然8019被另一个项目给占用了

这里我们可以去这个项目下面看看他的tomcat里面的server.xml所对应的端口号是多少

我们根据进程号查看这个项目所在的目录：ps -ef | grep 27772 (PID)

我们查询到27772(进程号)对应的目录是/data/rebatencenterManage/longandshortlink/tomcat/conf/

我们去这个目录端中查看server.xml的端口号 果然也是8019 所以冲突的问题找到了

那么我们可以选择修改两个tomcat中其中一个端口号只要不冲突就行 具体看第3步

3、打开tomcat下面的conf文件夹->server.xml

修改：port="8025"（这里我修改成了8025 只要不冲突就可以）

 <Connector port="8025" protocol="AJP/1.3" redirectPort="8443" />

注意：修改的是protocol="AJP/1.3"的这个不是server.xml上面的protocol="HTTP/1.1"

修改完成覆盖一下文件 或者直接在Linux中修改

启动一下tomcat  cd /tomcat/bin   ./startup.sh

问题解决！
