Hello,

if you set debug=3, do you see any other log message that can give hints about the error?

I do not recall any change in using mysql conf groups, but there were some changes in supporting usernames with domains and few other updates that could have affected indirectly this part.

Cheers,
Daniel

Hi List,

me again - i also updated the test-system to latest CentOS 7.7.1908 to be sure that the rpm building source and my target system are on the same versions.

Hi List,

i updated one of my testing kamailios from 5.2.x to latest 5.3.x.

After restarting the process, i got an mysql error that the server "kamailio" is not found.

I use the config-feature of my.cnf config-group names within the kamailio.cfg
I can start my kamailio 5.3.x installation with "normal username:password@host" definitions for DBURL.

Did anyone have the same issue?

from my kamailio.cfg i defined the DBURL like this:

# Use /etc/my.cnf.d/kamailio.cnf to store credentials
# within a mysql-db-group
#!define DBURL "mysql://[kamailio]/kamailio"

and special modules can use it like this (or via DBURL)
modparam("sqlops", "sqlcon", "cb=>mysql://[kamailio]/kamailio")

cat /etc/my.cnf.d/kamailio.cnf

# MySQL configuration group for kamailio
[kamailio]
user=kamailio
password="kamailiorw"
host=172.20.100.22
