Suse 10.3, ZM 1.23.1 Can't connect to local MySQL server

Post by keynet » Sun Feb 17, 2008 4:54 pm

Hi

I've been struggling with this mysql error for a day or so, and tried searching the forums, but am now stuck.
I've tried both the rpm for Suse 10.3 and building from source with the pre-requisites. Both behave the same.

I get

Code: Select all

Feb 17 16:15:07 ha-server zmfix[17676]: ERR [Can't connect to server: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)]

zmpkg.log is

I have checked that mysql is running and used mysqladmin to checkout the basics - that looks OK, it's running.

So I tried editing my.cnf to change the socket location to /tmp/mysql.sock, restarted mysql (the socket location changes as expected), but now zmpkg gives the following error:

Code: Select all

DBI connect('database=zm;host=localhost','zm_admin',...) failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) at /usr/lib/perl5/site_perl/5.8.8/ZoneMinder/Config.pm line 89
Can't call method "prepare_cached" on an undefined value at /usr/lib/perl5/site_perl/5.8.8/ZoneMinder/Config.pm line 91.

Compilation failed in require at /usr/local/bin/zmpkg.pl line 45.
BEGIN failed--compilation aborted at /usr/local/bin/zmpkg.pl line 45.
It appears like different parts of the program are hardwired to look in different places for the socket, and both can't be right at the same time.
Can I change where zmfix is looking for the socket - can't see anything obvious in the source.
But maybe it's some kind of simple permissions problem instead?

Help much appreciated

They can sometimes be configured to be in different places. This is a mysql and perl issue rather than ZM. Off the top of my head I can't remember where this config is set so the easiest thing I normally recommend is just creating a soft link from one to the other.

So

Code: Select all

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
for example, though do it whichever way round so that the one that exists is first. That way whenever one is created so will the other be.
