chkconfig not starting application script on bootup
chkconfig essentially makes a symlink from, say, /etc/rc3.d/S85myapp to /etc/init.d/myapp. Verify that those links exist. I assume they do, since the "chkconfig --list" is showing that they're "on".
Since you can execute /etc/init.d/myapp from prompt, but it doesn't occur during startup, my guess is that there's an issue with the PATH, or that a service that you need up and running before executing myapp is actually initializing after myapp. Remember that the scripts in /etc/rc3.d (or whatever your initial runlevel is) are executed in sort order. Verify that myapp has everything it needs to run.
(My guess it that there's a PATH issue, though)

gAMBOOKa almost 2 years
OS: Centos 5.7
My application script starts like this (/etc/init.d/myapp):
#!/bin/sh # chkconfig 2345 85 60 # description: my application controller # processname: myapp NAME=MyApp DIR=/opt/myapp/ RUN_AS=root ### BEGIN INIT INFO # Provides: myapp # Required-Start: $all # Required-Stop: $all # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Description: Starts the myapp application ### END INIT INFO
Chkconfig status
chkconfig --list | grep myapp myapp 0:off 1:off 2:on 3:on 4:on 5:on 6:off
myapp accepts start | stop | restart | force-reload and they're all tested to work
myapp controller basically needs to start some daemon services for the application. If I run
service myapp start
after the system is rebooted, everything works fine. But for some reason, chkconfig is not starting it up automatically. Can anyone explain what I may be doing wrong?UPDATE:
Thanks to cjc's information, it appears that my application controller is loading prior to some required services such as mysql.
Here's the result of a quick search:
find /etc -name rc* -type d | xargs ls | grep myapp K50myapp K50myapp S50myapp S50myapp S50myapp S50myapp K50myapp
So why is the order set to 50 when in the script I've set to 85(start) 60(stop)? And how can I change this?
Solution (as pointed out by cjc in comments to his answer)
Incorrect syntax:
# chkconfig 2345 85 60
Correct to (colon needed after chkconfig):
# chkconfig: 2345 85 60

gAMBOOKa over 12 yearsThey're current showing up in
/etc/rcx.d/S50myapp
, and you're right, some services that are required load up after this. Like mysql isS62mysql
. How can I change this sort order? -
cjc over 12 yearsCheck the man page for chkconfig, the "RUNLEVEL FILES" section. Basically, the "# chkconfig 2345 85 60" line in your file. From that, it should be S85, which would start it after mysql. I guess you may have created the links prior to changing that line. In this case, I'd do "chkconfig --del myapp" to remove the links, and then "chkconfig --add myapp" to add them again. In the worst case, you can rename the symlinks in the /etc/rc?.d directories.

chkconfig --del myapp
does delete all the symlinks. Butchkconfig --add myapp
again sets them S60myapp. If I rename them manually, it might be an issue in the future if someone else decides to make changes to the script. I can't understand why it's being set to 50 when I'm clearly setting it to 85 60. -
gAMBOOKa over 12 yearsThat was it! Thanks cjc. Appreciate your patience with this!

Yuval over 10 yearsThanks for the tip about the $PATH -- it lead me to check my init file, and it seems it was using a pid.lock file but not actually checking that the process was up, which caused a stale lock file preventing the daemon from starting. Thought it might help others if I mention this scenario.
