CentOS 7 安裝與卸載MySQL 5.7

先介紹卸載

防止重裝

• yum方式

  查看yum是否安裝過mysql
  yum list installed mysql*

如或顯示了列表，說明系統中有MySQL

• yum卸載
  根據列表上的名字

  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查看安裝

  rpm -qa | grep -i mysql

• rpm 卸載

  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/

• 清除餘項

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

• …
  我就省略了

• 刪除配置

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

剩餘配置檢查

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

根據上面的列表，刪除 ,如：mysqld
