I have a MySQL server running on Amazon EC2 in a VPC instance. I had to change the instance type of it to handle load and when I brought it back up, the socket didn't exist anymore. The file /var/run/mysqld/mysqld.sock doesn't exist and nor does the directory.
I have no idea where it went, but it is just gone. So is there a way to fix that? If so how? The server is running Ubuntu 10.04.
