calibre startup script
 

I have installed calibre from sbopkg with all dependencies. The program works as a GUI application from a desktop. Program aslo works when I type the service as on cli with same arguments as in my script.
When I execute the script I put together it does not work. It tells me service started but does not start.

Can someone have a look and see why this is not working. I have gotten this far but lack the finishing touch.

Thx

Does the calibre user have write permissions on the log and error files, and execute permission on the var/lib/calibre parent directory?

How do you check that the calibre-server is running?
What do you see when you run the script as "sh -x /path/to/yourscript start" ? Perhaps the script fails halfway.

I use a similar script that starts several calibre content servers, and it has been working for years.

calibre startup script
 

I had the /var/lib/calibre directory as 0755 and the two log files as 0664.

When I run the script sh -x I get some interesting results:
=====================================================================
Run #1
[michealj@orion run]$ sh -x /etc/rc.d/rc.calibre-server start
+ CONTENT=/usr/local/pub/calibre
+ CALIBRE_LOGFILE=/var/lib/calibre/calibre-server-log
+ CALIBRE_ERRORFILE=/var/lib/calibre/calibre-server-errors
+ PORT=8080
+ CALIBRE_USER=calibre
+ DAEMON=/usr/bin/calibre-server
+ PIDFILE=/var/run/calibre-server.pid
+ ARGS='--auto-reload --with-library=/usr/local/pub/calibre --pidfile=/var/run/calibre-server.pid --port=8080 --daemonize'
+ case "$1" in
+ calibre_start
+ calibre_status
+ ps aux
+ grep /usr/bin/calibre-server
+ grep -v grep
+ return 3
+ '[' 3 = 0 ']'
+ echo 'Starting Calibre Server...'

[michealj@orion run]$ /etc/rc.d/rc.calibre-server: line 41: /var/lib/calibre/calibre-server-log: Permission denied

But the permission from the files looked good, RWX on dir and RW on the files. I dont know.

====================================================
Run #2 after I removed the logging from the startup script, I now get another error.
[michealj@orion run]$ sudo sh -x /etc/rc.d/rc.calibre-server start

+ ARGS='--auto-reload --with-library=/usr/local/pub/calibre --pidfile=/var/run/calibre-server.pid --port=8080 --daemonize'
+ case "$1" in
+ calibre_start

=========================================================
When I check to see if the server is running:
[michealj@orion run]$ sudo sh -x /etc/rc.d/rc.calibre-server status
+ CONTENT=/usr/local/pub/calibre
+ CALIBRE_LOGFILE=/var/lib/calibre/calibre-server-log

===================================================
I am stumped. Must have something to be with running it as a user. Do you normally run this type of service with root permissions ?

The issue has to be around how I created the "calibre" user and when trying to run the script as that user and not root.

Anyone ?

I believe that the problem is the stdout and stderr redirection occurs before the user is switched -- thus the log and errors files are owned by root, not calibre.

Try moving the second quote to the end of the line.

I removed the log files completely and tried su - $CALIBRE_USER -c "$DAEMON $ARGS" & but still no joy.

I think maybe I need to delete this user and start again. There something wrong with the user interaction because if I run the script as root #/usr/bin/calibre-server --with-library=/calibre --daemonize it works.
I tried running the script as my normal user and it failed as well. IS there a group the user must be in for this to work ?
