Hi all,

I'm quite new using mysql, so let me know if I'm missing something. I took some holidays, and when I got back to work and I tried to log in phpmyadmin I got a ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2).

I never had this problem, so I was browsing to look for a solution. I tried some things, and I'm afraid I touched too much. I couldn't solve the problem, and the I realized that I had some actualizations to be done, and I thought that they may be helpful for mysql. Then I also realized that when I was doing this actualizations first day, they stopped because I had a lack of space, so I restarted then. Then,when the system was configuring mysql, it didn't advance. I waited for a long time and then I just stopped it and restarted the computer. After it, I just tried to uninstall mysql with sudo apt-get remove mysql-server-5.1, and install it again, but it didn't work. Now I have 2 questions:

1. What do you think it is happening? Should I remove mysql completely? What should I do?
2. I'm afraid of losing my databases, is there anyway to recover the data?

Thank you very much in advance.
