Tomcat start up error | 易学教程

问题

I am getting the following error in the Catalina log file while starting Tomcat on Windows:

Sep 3, 2010 3:22:53 PM org.apache.catalina.startup.Catalina start
SEVERE: Catalina.start: 
LifecycleException:  service.getName(): "Catalina";  Protocol handler start failed: java.lang.Exception: Socket bind failed: [730048] Only one usage of each socket address (protocol/network address/port) is normally permitted.

Sep 3, 2010 3:22:53 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 67604 ms

But when I changed the port number from 8080 to 9000 then there was no error but the request to http://localhost:9000/ gives the 404 error The requested resource (/) is not available.

Am I missing something?

回答1:

One application is using the 8080 port. To find out which one, use the following command on Windows Command Prompt:

C:\>netstat -aon | findstr 0.0:8080

Then take the number in the last column (that's the process ID) and find out which is the process in task manager. If nothing comes out of the command, then you have no application using that port.

回答2:

C:\>netstat -aon | findstr 0.0:8080

This had fixed it , by just clearing the process with this id from the processes and restarting TomCat.

回答3:

You need to start tomcat at port 80 as root user.Other port do not.

回答4:

Another process is using that port (probably another Tomcat instance).

If you don't want to use another port for your actual Tomcat instance, you need to kill that process.

cmd

1 line

for /f "tokens=5" %a in ('netstat -ao ^| findstr 0.0.8080') do taskkill /pid %a

2 lines

get PID

netstat -ao | findstr 0.0:8080

you get something like this:

TCP    0.0.0.0:8080           0.0.0.0:0              LISTENING       5180

(the last value is the PID - use it in the following command)

kill process
```
taskkill /pid <pid>
```
