tomcat not starting

问题:

suddenly for some reason tomcat server is not runnin/starting/stopping.

below is the result I get when i run the startup command,

  C:\Program Files\jasperserver-3.5.0\apache-tomcat\bin>startup
Using CATALINA_BASE:   C:\Program Files\jasperserver-3.5.0\apache-tomcat
Using CATALINA_HOME:   C:\Program Files\jasperserver-3.5.0\apache-tomcat
Using CATALINA_TMPDIR: C:\Program Files\jasperserver-3.5.0\apache-tomcat\temp
Using JRE_HOME:        C:\PROGRA~1\JASPER~1.0\java\jre

The tomcat window pops up for a split of a second and goes away.

(I have another java instance installed under c:\program files)

Help!!!

回答1:

Use catalina.bat run instead of startup.bat. Then the window won't go away and you can see what's going on

回答2:

In my case that was a problem with final slash in %CATALINA_HOME% path: final slash should not be there!

C:\tomcat\8.0.30 - correct

C:\tomcat\8.0.30\ - wrong

See http://blackandwhitecomputer.blogspot.de/2015/09/tomcat-debug-cannot-startup.html

Honestly, I had not expected modern applications may be depended on final slash in environment variable path!

回答3:

Hmm it's very strange problem because in the log you have that server started, so try this:

• restart computer :) - the best solution for strange situations
• change tomcat port
• close every unnecessary applications: skype, ip phones etc (I've encountered similar problem someday and application ip phone "softly" blocked this port ("softly" - in tomcat log everything was OK but in reality webapp doesn't work)

回答4:

Add tomcat in your eclipse and start it from there. Configure tomcat as 'Use Tomcat installation'. It will work

回答5:

I ran into a similar problem. I open cmd prompt and cd to tomcat\bin\startup.bat. The issue was my JRE_HOME not defined in the environment variables. I added and it worked.

回答6:

I had the same problem and I solved it this way:

First, following @ykaganovich suggestions, I tried to start the server using the catalina.bat start command; it did not solve the problem, but at least it showed a log that specified the error, which was really helpful.

In my case, the log said that the problem was because of the java versión. I had the JAVA_HOME variable pointing to the JDK7, but my tomcat version needed it to point to the JDK8.

I changed the JAVA_HOME variable to point to JDK8 (instead of JDK7) and then , when I executed the catalina.bat start command again, it worked perfectly and the server started. I hope my suggestion could be helpful to someone.

回答7:

If Tomcat was earlier working fine and Tomcat not starting happens unexpectedly, it's because some other process has started using the port you were using Tomcat on. In my case, I had shutdown Tomcat and was trying to run my servlet directly from Eclipse. So Eclipse took control of the port. After I closed Eclipse and tried restarting Tomcat (with startup.bat), everything worked fine.

ykaganovich's answer helped me track down my issue.

Try to open Tomcat7w.exe or follow the below steps.

(I have installed Tomcat under folder C:\Program Files\Apache Software Foundation\Tomcat 7.0)

1. open command prompt as Administrator
2. run --> "C:\Program Files\Apache Software Foundation\Tomcat 7.0\bin\Tomcat7w.exe" //MS//
3. now you can see icon in the system tray
4. double click on icon and start/stop
