auto start script

Hi

How to i make this to start automatically
5 * * * * /opt/jdk1.5.0_06/bin/java -jar /path/to/jwwim_server_sql2.jar localhost web1_db4 PASSWORD 5190 -l

Thanks.

 

Do you want to have this as a cron job? Then run

Code:

crontab -e

and enter that line there.

 

You realise that will run at 5 past every hour?

If you mean you want it to start when the box is restarted then some versions of cron (such as Redhat) support @reboot so your crontab entry would be
@reboot /opt/jdk1.5.0_06/bin/java -jar /path/to/jwwim_server_sql2.jar localhost web1_db4 PASSWORD 5190 -l

 

If you want to start it at boot time, you simply create a script like /etc/init.d/jwwim_server_sql2:

Code:

#!/bin/bash
/opt/jdk1.5.0_06/bin/java -jar /path/to/jwwim_server_sql2.jar localhost web1_db4 PASSWORD 5190 -l

Then run

Code:

chmod 755 /etc/init.d/jwwim_server_sql2

and create the necessary system startup links. Depending on your distribution you can do it with chkconfig (RedHat, Fedora, CentOS, Mandriva, SuSE) or update-rc.d (Debian, Ubuntu).

 

Can any program be made to run at startup? for example: a teamspeak server, and a counter strike server. As long as i use the startup commands for the respective servers, in the code?

 

Yes, of course.

 

will the above run the commands as root ?
is there a way to create a delay ?
i need to start 2 programs and the first must be already started when the second starts.
i hope this works for centos 5 !

 

Yes.

You can either use the sleep command (see

Code:

man sleep

), or create two cron jobs where the second one is executed after the first one.
