a. sudo apt-get autoremove --purge mysql-server-5.0 b. sudo apt-get remove mysql-server c. sudo apt-get autoremove mysql-server d. sudo apt-get remove mysql-common (非常重要)
2. 清理殘留資料
dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P如果報如下錯誤，證明你的系統中沒有殘留配置檔案了，無須擔心。
--------------------------------------------------------------------------------
dpkg: --purge needs at least one package name argument
Type dpkg --help for help about installing and deinstalling packages [*];
Use `dselect' or `aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;
Type dpkg --license for copyright license and lack of warranty (GNU GPL) [*].
Options marked [*] produce a lot of output - pipe it through `less' or `more' !
下面安裝mysql5.6你必須先刪除這些資料夾：
