Default Squeeze at boot: mydns ... failed!
Not sure what caused this (maybe the update to Squeeze), buthen I re-boot the Debian Squeeze server I get the following error(s)

Code:
Starting DNS server: mydnsmydns[1395]: Error connecting to MySQL server at localhost: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) (errno=2)
Starting MySQL database server: mysqld . ..
..
..
..
startpar: service(s) returned failure: mydns ... failed!
I need to login after this and start the mydns by hand.
Code:
/etc/init.d/mydns start
Anyone here who might know what could cause this?

Looks like 'mydns' is started before your 'mysql' server and it depends on mysql so that's why it's failing to start on boot. anyhow, can you post the output of:

Code:
# ls -la /etc/rc3.d/ | grep S
thanks,

yes, there's the problem. a quick fix is to rename the S19mydns symlink to something like S99mydns for example.

when mysql server is started is there an unix socket mysqld.sock in the location specified by the error /var/run/mysqld/mysqld.sock ?

At the moment I do not know (and can not reboot the server again...)
I will reboot again tonight, and report back.

Thank you for your help.

you don't need to reboot the server to see if there is or not mysqld.sock

My misstake

Code:
host:/var/run/mysqld# ls -l
total 4
-rw-rw---- 1 mysql mysql 5 Jul 10 13:23 mysqld.pid
srwxrwxrwx 1 mysql mysql 0 Jul 10 13:23 mysqld.sock
And
Code:
host:/var/run/mysqld# ls
mysqld.pid  mysqld.sock
host:/var/run/mysqld#
So yes... mysqld.sock does exists

that's strange ... mysqld seems that is starting fine
try also runing mysql_upgrade script and see if that's working , it should fix the tables after upgrading
