I'm running MySQL in Ubuntu 9.10. I installed MySQL this afternoon, and it worked just dandy. I logged off and shut down the laptop. When I got back on tonight, I get the following error when I run mysql:
Code:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
If I run mysqld, I get this message:

Code:

I'm quite new to this, so any and all comments are welcome. I have no idea what FEDERATED is, or how to install it, and I have no idea how to check if another mysqld server is running. Please help!
