Are you performing a new installation or trying to connect to an existing MySQL database in which you migrated over to the linux box? Have you check your file permission on step 1 or 2 of the setup? Make sure that you are also entering the correct root password for MySQL and not for the Linux O/S when you are on the step to create the database.
You are right ! Mysql client is not responding. I tried installing phpmysqladmin but it breaks with a file not found error for “mysql.so” . Looks like this file should be there along with the client package but its not it seems. I am using Unbreakable Linux from Oracle. I do see the client packages are installed but unable to locate the directory where these packages throw their programs.
