Hi Sergey,

i set in my /etc/hosts an host entry names kamailio to see more.

i tried that and i saw that the process kamailio is trying to reach "host: kamailio" with user=kamailio schemata=kamailio and password=kamailio on the wire.
That seems to be the "defaults" if no values is found.

I thing that the IPv6 Patch Idea from Daniel is more the root-cause [] is essential in ipv6 and its an pointer for DBURL/mysql-groups.

Could you record network traffic into PCAP like
tcpdump -ni any host ${mysql_server_ip} -s 0 -w /tmp/mysql.pcap

then sent.Will try look into network traffic.

Hi Daniel,


 0(29174) DEBUG: db_mysql [km_my_con.c:108]: db_mysql_new_connection(): opening connection: mysql://xxxx:xxxx@kamailio/kamailio
I dont know where kamailio though that there is an "hostname" kamailio that holds the mysqldb/kamailio.

I want to use groups in the future - cos i auto-generate mysql-passwords with / for example and that is possible in groups, but i dunno how in normal defines.

Cheers

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,

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
