解决：Unable to open debugger port (127.0.0.1:55017): java.net.SocketException "Socket closed"

遇到问题

项目以前启动正常，突然报错，启动不起来了，报了个 Unable to open debugger port (127.0.0.1:55017): java.net.SocketException "Socket closed" 这个错。

报错, 查了其他的有说是端口被占用。然后按照步骤，改了 debug 的端口，没有生效。

解决步骤：

1.打开Event Log(View->Tool Window->Event Log)

11:23   Error running 'distrib-web': Cannot run program "/Users/mac/apache/apache-tomcat-7.0.86/bin/catalina.sh" (in directory "/Users/mac/apache/apache-tomcat-7.0.86/bin"): error=13, Permission denied
11:23   Error running 'distrib-web': Unable to open debugger port (127.0.0.1:5521): java.net.SocketException "Socket closed"

chmod a+x catalina.sh
