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
根据上面的列表,删除 ,如:mysqld
