linux下MySQL卸載方法
一.源碼安裝的卸載方法：
到源碼目錄，如果可以運行make uninstall就可以卸載。如果沒有，就直接刪除。
如果是./configure --prefix指定了目錄用 rm -rf 目錄名 刪除
-------------------------------------------------------------
[root@localhost ~]# cd /usr/local/src/mysql-5.1.45
[root@localhost mysql-5.1.45]# make uninstall
[root@localhost mysql-5.1.45]# cd ..
[root@localhost src]# rm -rf mysql-5.1.45
[root@localhost src]# cd ..
[root@localhost local]# ls
bin etc games include lib libexec mysql sbin share src web
[root@localhost local]# rm -rf mysql/
[root@localhost local]# ls
bin etc games include lib libexec sbin share src web
[root@localhost local]#
-------------------------------------------------------------
二.rpm方式安裝的卸載方法：
查看是否安裝mysql的命令
rpm -qa | grep mysql
然後 逐個使用 rpm -e mysq-* 卸載
如果出現
error: Failed dependencies:
libmysqlclient.so.10 is needed by (installed) libdbi-dbd-mysql-0.6.5-10.RHEL4.1.i386
libmysqlclient.so.10 is needed by (installed) MySQL-python-1.0.0-1.RHEL4.1.i386

mysqlclient10 = 3.23.58-4.RHEL4.1 is needed by (installed) mysqlclient10-devel-3.23.58-4.RHEL4.1.i386
時，使用 --nodeps 參數，如：
rpm -e mysqlclient10-devel-3.23.58-4.RHEL4.1 --nodeps
rpm -e mysqlclient10-3.23.58-4.RHEL4.1 --nodeps
