CentOS7 卸载mysql（YUM源方式）

 

防止重装

• yum方式

查看yum是否安装过mysql
yum list installed mysql*

如或显示了列表，说明系统中有MySQL

yum卸载 

根据列表上的名字

 

yum remove mysql-community-client mysql-community-common mysql-community-libs mysql-community-libs-compat mysql-community-server mysql57-community-release
rm -rf /var/lib/mysql  
rm /etc/my.cnf

rpm查看安装

rpm -qa | grep -i mysql

 

 

rpm 卸载

rpm -e mysql57-community-release-el7-9.noarch
rpm -e mysql-community-server-5.7.17-1.el7.x86_64
rpm -e mysql-community-libs-5.7.17-1.el7.x86_64
rpm -e mysql-community-libs-compat-5.7.17-1.el7.x86_64
rpm -e mysql-community-common-5.7.17-1.el7.x86_64
rpm -e mysql-community-client-5.7.17-1.el7.x86_64
cd /var/lib/  
rm -rf mysql/

清除余项

whereis mysql
mysql: /usr/bin/mysql /usr/lib64/mysql /usr/local/mysql /usr/share/mysql /usr/share/man/man1/mysql.1.gz
#删除上面的文件夹
rm -rf /usr/bin/mysql

 

… 
… 
我就省略了

 

删除配置

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

剩余配置检查

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