mysql-devel-5.6.27-1.el6.x86_64

[root@localhost mysql]# rpm -e mysql-server-5.6.27-1.el6.x86_64

[root@localhost mysql]# rpm -e mysql-client-5.6.27-1.el6.x86_64

[root@localhost mysql]# rpm -e mysql-devel-5.6.27-1.el6.x86_64

[root@localhost rc.d]# cd /var/lib/

[root@localhost lib]# rm -rf mysql/注:刪除mysql資料庫目錄(關鍵) ,否則password不更新(預設安裝,如果自定義安裝路徑和鏈結路徑ln -s ……請刪除。)

? rm -rf /var/lib/mysql

解除安裝3:

[root@localhost usr]# whereis mysql

mysql: /usr/lib64/mysql

[root@localhost usr]# rm -rf /usr/lib64/mysql注:find / -name mysql

注:清空相關mysql的所有目錄以及檔案和其他配置和設定等。如果有,則刪除。也必須考慮其他軟體不去影響。

rm -rf /usr/lib/mysql

rm -rf /usr/share/mysql

解除安裝4:

[root@localhost usr]# rm –rf /usr/my.cnf

[root@localhost usr]# rm -rf /root/.mysql_sercret解除安裝5(自啟服務):

[root@localhost usr]# chkconfig --list | grep -i mysql

[root@localhost usr]# chkconfig --del mysqld此處刪除看自己設定:mysql/mysqld
