方式1:
[root@localhost usr]# yum list installed mysql* Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.yun-idc.com * extras: mirror.neu.edu.cn * updates: mirrors.yun-idc.com Installed Packages MySQL-client.x86_64 5.6.27-1.el6 installed MySQL-devel.x86_64 5.6.27-1.el6 installed MySQL-server.x86_64 5.6.27-1.el6 installed [root@localhost usr]#
方式2( -i :不区分大小写):
[root@localhost usr]# rpm -qa | grep -i mysql MySQL-server-5.6.27-1.el6.x86_64 MySQL-client-5.6.27-1.el6.x86_64 MySQL-devel-5.6.27-1.el6.x86_64 [root@localhost usr]#
2、卸载MySQL
卸载1:
[root@localhost usr]# yum remove mysql mysql-server mysql-libs compat-mysql51 [root@localhost usr]# rm -rf /var/lib/mysql [root@localhost usr]# rm /etc/my.cnf
如果装了mysql-devel(其他一样add command),卸载为:
[root@Tony_ts_tian init.d]# yum remove mysql mysql-devel mysql-server mysql-libs compat-mysql51
注(例如):
mysql-5.5.39-1.el6.remi.x86_64
mysql-libs-5.5.39-1.el6.remi.x86_64
compat-mysql51-5.1.54-1.el6.remi.x86_64
mysql-server-5.5.39-1.el6.remi.x86_64
卸载2{继续,1,2选择一种(此处为介绍):}:
[root@localhost mysql]# rpm -aq | grep -i mysql MySQL-server-5.6.27-1.el6.x86_64 MySQL-client-5.6.27-1.el6.x86_64 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:删除MySQL数据库目录(关键) ,否则password不更新(默认安装,如果自定义安装路径和链接路径ln -s ……请删除。)
rm -rf /var/lib/mysql
卸载3:
[root@localhost usr]# whereis mysql mysql: /usr/lib64/mysql [root@localhost usr]# rm -rf /usr/lib64/mysql
注:find / -name mysql
注:清空相关mysql的所有目录以及文件和其他配置和设置等。如果有,则删除。也必须考虑其他软件不去影响。
rm -rf /usr/lib/mysql
rm -rf /usr/share/mysql
卸载4:
[root@localhost usr]# rm –rf /usr/my.cnf [root@localhost usr]# rm -rf /root/.mysql_sercret
卸载5(自启服务):
[root@localhost usr]# chkconfig --list | grep -i mysql [root@localhost usr]# chkconfig --del mysqld
此处删除看自己设置:mysql/mysqld
