Re: [SR-Users] Returning problem

Hi, Please notice that the original problem is Kamailio starting before MySQL on Ubuntu and that the reason is because Kamailio is using the standard init.d script and MySQL is using upstart. Now, installing MySQL server on Ubuntu is a quite simple command: apt-get install mysql-server (and this is what I do to get it installed). We can conclude that the MySQL package for Ubuntu, from the official repositories, is already using Upstart. So, to solve the starting problem you must either change MySQL back to init.d or Kamailio to Upstart. I don't believe that moving MySQL back to init.d would be a good idea as anytime you do an upgrade from the repositories you could end up having problems with the start script. Also, you would have to maintain you own start script. Of course it is up to anyone decide the best way. But the key point is: installing Kamailio+MySQL on Ubuntu will fail to start Kamailio at the boot time if Kamailio does not include the proper Upstart configuration. Cheers!

Perhaps it would be good to be added in the tracker not to get lost. As said, I am not familiar with upstart, maybe someone else can contribute other improvements for the moment. Btw, is upstart the default init system for ubuntu 12.04, or is just an alternative? Kamailio is packaged on official Debian distro, I wonder if the follow the same init system already.

If you are using another distro or version, you may need to adapt the upstart script. Also, I am not sure if this is the right way of doing it, but it worked for me... Finally, I did not convert some of the start-up scripts. Now, the problem I see is that this addresses "my problem" (Kamailio+MySQL on Ubuntu running Upstart). However, it would be nice to have a more complete script. I.e.: If you are not running MySQL, then you have to change the upstart script to match your SQL engine. The old init script had a "Should-Start" statement so you could get anything to start before Kamailio (postgresql mysql radius, etc.) without being a "must" like in upstart. But I could not find the equivalent command for this in Upstart docs... So I let here the challenge for the community to improve what I could accomplish so far. The first thing you need to do is to remove (or not install) the /etc/init.d/kamailio init script. Then you need to create a symlink to the kamailio upstart conf file that should be at /ect/init/. To do so: # First save you original init script if you have one mv /etc/init.d/kamailio ~ # Create symlink to upstart .conf file ln -s /etc/init/kamailio.conf /etc/init.d/kamailio Then create a /etc/init/kamailio.conf (notice it is /etc/init/ not /etc/init.d/) with the following content: # Kamailio Service description "Kamailio server" author "Moacir Ferreira" # Change anything here # to match your environment env NAME=kamailio env DAEMON=/sbin/kamailio env CFGFILE=/etc/kamailio/kamailio.cfg env USER=kamailio env GROUP=kamailio start on runlevel [2345] stop on starting rc RUNLEVEL=[016] # This is required to start Kamailio # after MySQL start on started mysql # This is required when the daemon # forks 2 times expect daemon # Include this to see the nice # kamailo init messages at the console console output pre-start script # Do not start kamailio if fork=no is set in the config file if grep -q "^[[:space:]]*fork[[:space:]]*=[[:space:]]*no.*" $CFGFILE; then echo "$NAME ERROR: Kamilio not set to fork. Review your config or start it in debug mode."; exit 1; fi # Check if kamailio configuration is valid before starting the server. out=$($DAEMON -c 2>&1 > /dev/null) retcode=$? set -e if [ "$retcode" != '0' ]; then echo "$NAME ERROR: Config file invalid." exit 1; fi end script exec $DAEMON -f $CFGFILE -u $USER -g $GROUP # This is the end of the script Good luck and Cheers!

I have done some "reading" and found that Ubuntu has changed to upstart http://upstart.ubuntu.com/cookbook/. However, I could not find how I can start a non "upstart" style init script like Kamailio has before the upstart styled ones... I guess that I have to either to get the Kamailio community to create an upstart script or find some help from the Ubuntu community how to overcome the problem. Anyway, I think the Kamailio team should address it as it will become a problem for everyone using Kamailio on Ubuntu. Any help? the link to the upstart documentation you gave has quite big content, couldn't you find a migration guide from classic init.d to upstart somewhere out there on the web? Might be easier to do it then.

There You'll find the answer. Edson.
