Linux under Idea and other tools debugging project prompt: Unable to open debugger port

When debugging a project under Ubuntu, use the Tomcat container, and after setting up the appropriate Tomcat LOCAL path and related information, click Debug Project to appear:

Unable to open debugger port:java.net.SocketException "Socket closed"

Search the Internet a lot of, as if all with their own situation is different.

Accidentally found that the. Sh in the bin directory of Tomcat has no executable permission. Decisively switch to the bin directory:

chmod +x *.sh;

Everything went smoothly.

It turns out that the executable attribute was removed when the file was extracted. It seems that the reason for using Xwindow to extract files, there is a similar situation please see if it is my case.

The same is true for Mac
