I've set up an Ubuntu server and wanted to install MySQL 5.5. I've been following these MySQL documentation steps.

I have libaio dev installed. Everything went fine until I ran

bin/mysqld_safe --user=mysql &

It runs into an issue and never returns to the shell. The output of mysqld_safe is logging to /usr/local/mysql/data/host_name.err.

When I checked that file, it was complaining about /tmp/mysql.sock. I can unfortunately describe just parts of the error, since before I started right now it deleted all the files I've started installing back then by mistake.

Should I change the socket to /var/run/mysqld/mysqld.socket after copying the .cnf file to /etc?

I've also checked the /var/run/mysqld directory and there is no mysqld.socket. How do I proceed?

Thanks for reading this and helping out
