Heip,

I have problem with Ubuntu 10.04.2 Server edition.
It was sabotaged by deleting all the mysql and mysqld folders in it.

Tryed removing, reinstalling mysql, but it does recreate only few folders and files.
Default files that come with base install of ubuntu are still gone. Without them i cant start the MSQL server.
The MSQL was not configured nor had any DB's, but I have a need for MySql now.

For example my mysqld.sock is missing. Linking the one in /tmp does not work.

I have no backup.

Hope this isn't too late.
Run

sudo apt-get remove --purge mysql-server*
sudo apt-get install mysql-server
# add more package if needed
# if necessary run:
#dpkg-reconfigure mysql-server-VERSION

Hi Junior

I bet /var/run/mysqld dir was also removed. I did purge remove and also install again without errors and then i did dpkg reconfigure, entered new pw and that was it.

You might want to run service mysqld stop then service mysqld start.
That's the proper way to start mysqld.

[tcih]

root@gn49:/etc/init.d# service mysqld stop

mysqld: unrecognized service

root@gn49:/etc/init.d# service mysql stop

stop: Unknown instance:

root@gn49:/etc/init.d#

Have you tried service mysql start and then connect to the MySQL server?

[tcih]

After starting up is mysqld running?
First kill any mysqld running, then service mysql start.
If you get no error, then try to connect.
If you get errors, killall mysqld again to be sure, then mysqld --user=root --log-error and redirect the error to a log file.
Also post the files /var/log/mysql*

It can not be solved, have ben looking into this topic for verly long time, close please

[devper94]

I don't think this is a completely lost case.

Purge the MySQL packages, clean up everything left and install it again.
