CentOS 7 安装与卸载MySQL 5.7

先介绍卸载

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
