View Full Version : [ubuntu] Upgrade 8.10 to 9.04 then to 9.10, first step good...

not so much...
After the upgrade from 8.10 to 9.04, all was well. But after the upgrade from 9.04 to 9.10, I lost the MySQL server.
Now, I recall during the upgrade, I was asked if I wanted to keep the existing my.cnf file or replace it with a newer one. I did as suggested and kept the original as I had edited it before. The same question was asked with a couple other config files. I kept the original in each case.
After the first step, I checked the server was running and the websites were up, all was well. After the update to 9.10, when I checked the server, I get the following error:

error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

Can anyone point me in the right direction to getting this resolved?

What command do you use when you get that error?
You can use the following command to get all mysql entries in the syslog
grep -i 'mysql' /var/log/syslog

Check that /var/run/mysqld/mysqld.sock exists. You can use the ls command
ls -l /var/run/mysqld/mysqld.sock

check the status of your mysql server
sudo service mysql status

Thanks for the input.

I found the answer here http://ubuntuforums.org/showthread.php?p=9104694#post9104694

I had to comment out skip-bdb from my.cnf.
