[SR-Users] ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed

[Abdulaziz Alghosh]

Greetings,

i am at the final stages of emigrating from kamailio 3.0.3 to 5.1.0
including our own module. Unluckily, after writing the command " kamctl
start", the following error is popping up:


* PID file /var/run/kamailio.pid does not exist -- Kamailio start failed*

Thus, I used the command " kamailio -M 8 -E -e -dd " to get more debugging
Info and the output is detailing the following:

 0(10334) ERROR: db_mysql [km_my_con.c:129]: db_mysql_new_connection():
driver error: Can't connect to MySQL server on '192.168.1.207' (4)
 0(10334) ERROR: <core> [db.c:318]: db_do_init2(): could not add connection
to the pool 0(10334) ERROR: ABDUL_functions [ABDUL_chk.c:1069]: init_db():
failed to connect database URL=mysql://ABDUL:ABDUL@192.168.1.207/ABDUL
 0(10334) ERROR: ABDUL_functions [ABDUL_functions_mod.c:296]: mod_init():
Module ABDUL_functions not correktly initialized, pid[10334]
 0(10334) ERROR: <core> [core/sr_module.c:991]: init_mod(): Error while
initializing module ABDUL_functions
(//lib64/kamailio/modules/ABDUL_functions.so)

Seemingly the error relates to old databases url ( "URL=mysql://
ABDUL:ABDUL at 192.168.1.207/ABDUL" ) inside an old Kamailio.cfg file from my
3.0.3 package which I put under another different directory. This old
Kamailio.cfg file #includes my own module, so he is exporting this url.
Consequently, my module is trying to connect again to this databases.

I do not know why both kamailio.cfg (new: /etc/kamailio/kamailio.cfg and
old one out of /etc/kamailio) are both seen for kamctl or (/sbin/kamailio).
I know that my new url inside the new /etc/kamailio/kamailio.cfg is read
and connected but again not sure why my hidden old kamailio.cfg is still
being read as well.

the attached shows my init file for "SUSE Linux Enterprise Server 11
(x86_64)" and my used kamailio *default *file under /etc/default.

Thanks in advance and best regards
Abdulaziz
