I enabled debugging on the kamctl script and see these lines right before it fails:

+ minfo 'Starting Kamailio : '
+ '[' -t 1 -a -z '' ']'
+ echo -e '\E[37;33m\033[1mINFO: Starting Kamailio : \033[0m'
INFO: Starting Kamailio :
+ '[' -r /var/run/kamailio.pid ']'
+ '[' '!' -x ./kamailio ']'
+ '[' 1 = 1 ']'
+ ./kamailio -P /var/run/kamailio.pid
+ sleep 3
+ '[' '!' -s /var/run/kamailio.pid ']'
+ echo

+ merr 'PID file /var/run/kamailio.pid does not exist -- Kamailio start failed'
+ '[' -t 1 -a -z '' ']'
+ echo -e '\E[37;31m\033[1mERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed\033[0m'
ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed
+ exit 1
[root@registrar sbin]#


these are the main steps I followed to install it:

mkdir -p /usr/local/src/kamailio-3.1.0
cd /usr/local/src/kamailio-3.1.0

git clone --depth 1 git://git.sip-router.org/sip-router kamailio
cd kamailio
git checkout -b 3.1 origin/3.1

mkdir /usr/local/kamailio-3.1

make FLAVOUR=kamailio cfg

vi modules.lst to exclude db_mysql db_odbc from modules.lst

make PREFIX="/usr/local/kamailio-3.1/" all
make PREFIX="/usr/local/kamailio-3.1/" install

then I executed /usr/local/kamailio-3.1/sbin/kamdbctl create to create the DB and tables.

Subject: [SR-Users] kamailio fails to start with kamctl start

Hello
I just installed kamailio-3.1 and using the default config file "kamctl start" fails

 [root@registrar sbin]# ./kamctl start

INFO: Starting Kamailio :

ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed
[root@registrar sbin]#

but when I use this command it starts: <kamailio -f path_to_config_file

[root@registrar sbin]# ./kamailio -f /usr/local/kamailio-3.1/etc/kamailio/kamailio.cfg
loading modules under /usr/local/kamailio-3.1//lib64/kamailio/modules_k/:/usr/local/kamailio-3.1//lib64/kamailio/modules/

[root@registrar sbin]#

Also, when I use "./kamctl start" the syslog file does not show anything at all that would help me why it is failing.
But when I use "/usr/local/kamailio-3.1/sbin/kamailio -f /usr/local/kamailio-3.1/etc/kamailio/kamailio.cfg" it does update the syslog file.

Also, after kamailio start with "./kamailio -f .." I can use ./kamctl fifo <any option>. Example:

[root@registrar sbin]# ./kamctl fifo version
