Can't connect to local MySQL server through socket

This means:

1. MySQL crashed, it's not running or it can't find the socket. You need to contact Lunarpages support about this.

2. If your running a vBulletin board, then it means the info in your config.php file is wrong (in which case your forums wouldn't work at all).

Here is more info on this error:

MySQL 5.1:

MySQL 5.0:

MySQL 3.23, 4.0, 4.1:

Lost connection to MySQL server during query

Below are some of the most common reasons to receiving this error:

1. Because you have issued a ``close'' on your MySQL connection and then tried to run a query on the closed connection. You can check that the MySQL hasn't died by executing mysqladmin version and examining the uptime.

2. Are you trying to run a query against your database that is either incorrect or too large? If mysqld gets a packet that is too large or out of order, it assumes that something has gone wrong with the client and closes the connection.

3. Or your host has restarted mySQL. If this is the case, just simply contact the wonderful LunarPages support!

Not a problem at all Mitch.

I'm trying to execute this command: mysqldump --user=root --password=mypass --all-databases | gzip > db.gz

but it gives an error:
mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) when trying to connect

With reference to my search, the answer was, this problem is from the hosting company, kindly check the post of LincolnForums through this link out:
