Are you sure this isn't some kind of a firewall issue?  A simple, but slightly dangerous, test would be to:

    (1) Turn off the firewall
    (2) Try to make your connection
    (3) Regardless of the outcome of (2), immediately turn the firewall back on.

Subject: Re: [support] urgently need help for Site off-line error

hello Christopher,

i run apt-get install --reinstall mysql-server and start /etc/init.d/mysql start, but still got the same error "ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)".

i even create /var/run/mysqld/mysqld.sock file and then restart mysql, but the mysqld.sock file disappear and get the same error.

i got this problem when i finished install/configure drupal site and make it up and running, can browse the drupal site, loging from phpmyadmin, run /etc/init.d/mysql start without any issue, log to mysql from command line without any issue, then i restart the VM (use VM for this), then got the above problem.

The log is telling you that the users table doesn't exist. I don't know
how you installed mysql, or what distro you are using. If you installed
using a package management tool then an administrative user should have
been created. Review your installation process and make sure that all
the necessary databases and tables are there, including the one
mentioned in your logs. If you're using apt / dpkg and friends on a
debian system, then you might try something like

apt-get install --reinstall mysql-server
