[MySQL] Ubuntu 14.04 刪除所有舊的MySQL, 並重新安裝。

[Delete old mysql, and reinstall the new one.]


delete old mysql

sudo apt-get autoremove --purge mysql-server-5.0
sudo apt-get remove mysql-server
sudo apt-get autoremove mysql-server
sudo apt-get remove mysql-common

clear the package.

 dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P


Reinstall new server.

sudo apt-get install mysql-server
sudo apt-get install mysql-client

在剛才重新安裝的途中，他就會叫你設定root 密碼了。之後登入時會用到。
