PID file exists, but process is not running

问题

I'm working in centos6. I have installed tomcat6. At the first all works fine. But after restarting the server tomcat6 did not work properly.

When I execute this command line:"service tomcat6 status" I get: "PID file exists, but process is not running [ÉCHOUÉ]" I checked to the log file "catalina.out" and I get this error:

GRAVE: StandardServer.await: create[8005]:

Thanks in advance for your helps

If Tomcat's startup scripts are run with CATALINA_PID environment variable set properly, then the PID of the Tomcat process will be recorded to a file upon startup. If the file exists when you try to start Tomcat, the scripts will refuse to run because it does not want to clobber a (possibly valid) PID file.

If you are sure that Tomcat is not running, simply delete the file (it should be available through the CATALINA_PID environment variable) and try again.

If you want a self-re-starting service, considering looking at jsvc, which actually ships with Tomcat binaries in source form.

Which port you are running tomcat? port 80 or 8080? Any other services running on the same port? Did you check? You can kill tomcat using its process id

ps -ax | grep tomcat
kill -9 <PID>

if you are sure tomcat is the only java application you are running, then you can kill it using,

killall -9 java

watch the catelina.out using tail when you restart it.

something like this,depending on your installation method/path:

tail -f /usr/share/apache-tomcat-6.0.37/logs/catalina.out

Also check in you init scripts or setenv.sh where you configured this PID file. I never used it.

First of all Please find port or service name is running in linux services.

ps -ax | grep 8080

then Kill that process

Kill 8080

Then Start your tomcat with this command

sudo service tomcat start

It will Work.
