Ubuntu9.1 install and uninstall MySQL on the server

1. First install mysql-server-5.1
Sudo apt-Get install mysql-server-5.1 in this process, you need to enter the root user password, at this time do not enter, just press Enter. If you enter it, there will be problems, and I don't understand why. 2, then install mysql-serversudo apt-Get install mysql-server3, and then install phpmyadminsudo apt-Get install phpMyAdmin and then log on to http: // After the root password of phpMyAdmin user is empty, you can set a new password for the root user. Note: do not generate the new password automatically when you set it. If yes, remember the generated password. 4. UninstallThe uninstall process is the opposite of the installation process. Sudo apt-Get install mysql-serversudo apt-Get install mysql-server-5.1sudo apt-Get autoremove phpMyAdmin also deletes all configuration files under/var/lib/MySQL, this can solve the problem of losing the MySQL Root Password. Copy the database file to another directory. If the process is dead during apt-Get remove, use sudo dpkg-configure-A in other consoles.
