I have install mysql cluster on one of our linux machines, we did a pilot and decided to use replication instead. Now I want to remove it and install mysql-server.

I have removed all the old files as much as I could, now everytime I

apt-get install mysql-server

it seems to install but puts no files in /etc

I tried to purge the install and try again a few times with no luck.

Anyone have any ideas on how to completely remove mysql and start a new?

** Update **

Tried suggested purge remove

apt-get --purge remove mysql-server && apt-get clean && apt-get install mysql-server

Have you tried this?

apt-get --purge remove mysql-server && apt-get clean && apt-get install mysql-server


The purge failed because the removal script errored when it went to find a file. You'll need to get your package manager back to a consistent state; at first blush I would be tempted to reinstall mysql-server, do a touch on the missing file, and then do the purge all over, but I suspect that the script is probably trying to extract the password(s) that were stored in there, so this may not work either.

no luck with that, I update the question with the results – Brian G Jun 26 '09 at 16:22

You didn't say if you installed it via a package or from source. If you installed it by package, you will need to purge the package first. Debian packages have two states of removal; removed and purged. When you remove a package, it removes the files that were in the package, but leaves the configuration files and any directories that aren't empty. Purging a package runs an additional script that cleans up directories and additional files. You can purge a package by running:

# dpkg --purge package


# apt-get remove --purge package

This may not totally solve your problem. dpkg has special support for configuration files. It will not replace configuration files if they do not exist when you upgrade. This is so you don't delete a file, only to find an upgrade puts it back. You can fix this by telling dpkg to ignore this behaviour using --force-confmiss

# dpkg --force-confmiss -i /tmp/foo_2.0.0-14_all.deb

You should now find the configuration files are installed.

apt-get --purge remove mysql-server

apt-get clean

dpkg --force-confmiss -i /tmp/foo_2.0.0-14_all.deb


in my case is was: sudo dpkg --force-confmiss -i mysql-common_5.1.41-3ubuntu12.6_all.deb

and THAT replaced the /etc/mysql/my.cnf file that was missing. Yes, I dinked with it and lost it. My bad, but this fixed it!! Ric

The following finally worked for me:

apt-get --purge remove mysql-server mysql-server-5.1 mysql-common mysql-server*
