Tomcat Check Server Status - command, No found, start command

Question 1: Command for Check Status

May I know if there is any command method to call for Check Server Status such in the:

http://localhost:8080/manager/status?

• If the installed server is non-GUI, how you guys check Status example Total Memory.

I already googling but still cannot found it.

Question 2: What reason Not Found Check Server Status.

1 tomcat duplicate 2 which called tomcat1 and tomcat2 I encounter a problem when I click the Check Server Status using http://localhost:8080/manager2/status, 开发者_如何学Goit goes

Not Found The requested URL /manager2/status was not found on this server.

May I know where is manager2/status?

NOTE: Tomcat1 working accordingly.

Question 3: Tomcat Start command

All start tomcat method

1. /etc/init.d/tomcat start
2. /var/lib/tomcat2/bin/startup.sh
3. /var/lib/tomcat2/bin/catalina.sh

Can anyone tell me what different between them?

I'm looking for Question 1 too.. But there is no such thing "Check Server Status from Command Line" at Tomcat.

I didn't understand Question 2 actually. But if you want to create duplicate tomcat instances at the same time. You must change ports from "conf/server.xml"

First instance: http://localhost:8080/manager/status

Second instance: http://localhost:8081/manager/status

Like this.

Question 3:

/etc/init.d/tomcat start

This is a case start. You can stop or restart tomcat instance by typing /etc/init.d/tomcat stop or restart.

/var/lib/tomcat2/bin/startup.sh

Its a trigger for catalina.sh, you don't have to use this one. Its checking system, if catalina already running, it does nothing.

/var/lib/tomcat2/bin/catalina.sh

This is direct execution for Tomcat.

I prefer the case start. Seems more true.

Possible solution (though not very convenient) to question 1 can be found on Tomcat HOWTO page

Hope this helps...

Well, sorry I did not follow you on the 1 and 2 questions. But for the 3 question following are the differences/ multiple ways or starting/ running tomcat.

./catalina.sh run

Passing "run" argument for catalina.sh --> starts the Tomcat in the foreground and displays the running logs in the same console. when the console terminal is closed it will terminate the tomcat.

./catalina.sh start

Passing "start" argument for catalina.sh --> starts the Tomcat in the background. Since in background no issues closing down the terminal. The logs need to be viewed as below: tail -f $CATALINA_HOME/logs/catalina.out

./startup.sh 

The last way is firing the startup.sh to start your Tomcat server. If you Vi the script you can see it calls catalina.sh script passing start as the argument. This will be running in background as well.
