Just today one of my friend are pm me and ask how to make his tomcat service at \/etc\/init.d\/tomcat to run when the server reboot. At the first time i just tell him to use chkconfig because the os that he use was CentOS<\/p>\n

What is chkconfig ?<\/p>\n

Chkconfig is a basic system utility. It updates and queries runlevelinformation for system services. Chkconfig manipulates the numerous symbolic links in \/etc\/rc*.d, to relieve system administrators of some of the drudgery of manually editing the symbolic links.<\/p>\n

chkconfig<\/strong> –list<\/strong> [name<\/em>]
\nchkconfig<\/strong> –add<\/strong> name<\/em>
\nchkconfig<\/strong> –del<\/strong> name<\/em>
\nchkconfig<\/strong> [–level<\/strong> levels<\/em>] name<\/em> <on<\/strong>|off<\/strong>|reset<\/strong>>
\nchkconfig<\/strong> [–level<\/strong> levels<\/em>] name<\/em><\/p>\n

But when my friend use chkconfig there were error :<\/p>\n

# chkconfig –levels 235 tomcat on
\nservice tomcat does not support chkconfig<\/p>\n

okay my friend ask me what is the 235 means , 235 is runlevel that the script starts.
\nFor instance, if we called this script \/etc\/init.d\/new-service and ran chkconfig new-service on, it would be active in runlevels 2,3 and 5.<\/p>\n

0-6 are runlevels. Typically for Redhat based distributions:
\n0 – Halt the system
\n1 – Single-user mode
\n2 – Multi-user mode (without networking)
\n3 – Multi-user mode
\n5 – Multi-user mode, graphical login
\n6 – Reboot the system<\/p>\n

you can check your service run level by using chkconfig –list:<\/p>\n

# chkconfig –list

\nabout the service tomcat does not support chkconfig error , after some searching it turn’s out. In order to support chkconfig, an init script must:
\n1.\u00a0 Be located in \/etc\/rc.d\/init.d (which \/etc\/init.d is a symlink to)
\n2.\u00a0 Have a commented out line that contains “chkconfig: <default\u00a0 runlevels for this service> <start priority> <stop priority>”
