CentOS上装了Mysql如何清除干净?

#################CentOS7下MySQL的卸载####################
1:查看MySQL是否安装:
方式1:





# yum list installed mysql*Loaded plugins: fastestmirrorLoading mirror speeds from cached hostfile   * base: mirrors.yun-idc.com   * extras: mirror.neu.edu.cn   * updates: mirrors.yun-idc.comInstalled PackagesMySQL-client.x86_64   5.6.27-1.el6    installedMySQL-devel.x86_64    5.6.27-1.el6    installedMySQL-server.x86_64   5.6.27-1.el6    installed#

方式2( -i:不区分大小写):





# rpm -qa | grep -i mysqlMySQL-server-5.6.27-1.el6.x86_64MySQL-client-5.6.27-1.el6.x86_64MySQL-devel-5.6.27-1.el6.x86_64#   
2:卸载MySQL:
卸载1:





# yum remove mysql mysql-server mysql-libs compat-mysql51# rm -rf /var/lib/mysql# rm /etc/my.cnf
如果装了mysql-devel(其他一样add command),卸载为:





# yum remove mysql mysql-devel mysql-server mysql-libs compat-mysql51
注(例如):





# rpm -aq | grep -i mysqlMySQL-server-5.6.27-1.el6.x86_64MySQL-client-5.6.27-1.el6.x86_64MySQL-devel-5.6.27-1.el6.x86_64# rpm -e MySQL-server-5.6.27-1.el6.x86_64# rpm -e MySQL-client-5.6.27-1.el6.x86_64# rpm -e MySQL-devel-5.6.27-1.el6.x86_64# cd /var/lib/# rm -rf mysql/





# whereis mysqlmysql: /usr/lib64/mysql# rm -rf /usr/lib64/mysql





# rm –rf /usr/my.cnf# rm -rf /root/.mysql_sercret   





# chkconfig --list | grep -i mysql# chkconfig --del mysqld
