How to solve the 500 Internal Server Error on phpMyAdmin.

Yesterday I freshly installed my LAMP box, with mod_python. Everything was fine, but this morning while started to use phpMyAdmin, it generated the "500 Internal Server Error on phpMyAdmin", states the server is overloaded, blah blah blah.
My solution was to remove the ".htaccess" files under the phpMyAdmin directory.


To solve the remote login problem of MySQL.
Today, I cannot login to the MySQL server from remote computer, it said something like "cannot connect to remote host". The reason was the "skip-networking" was set to ON in the /etc/my.cnf file.

Comment the line to "#skip-networking" and restart the mysqld will solve the problem.
