mysql - 在 CentOS 7 上安装 MySql 失败

Question

为什么和mariadb有关系？我全新安装了 CentOS 7，想安装 MySql 社区版。好像说要先安装Mariadb服务器？

Answer 1

在 CentOS 7 中 - Maria DB 已经安装。因此，您正面临这个问题。{MariaDB 是 MySQL 的兼容实现}。如果你想安装 Mysql - 首先你应该删除当前现有的 Mari DB。

第 1 步:完全删除 Maria DB 即 yum -y 删除 mariadb-libs

第二步:安装MySQL

     i. wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
     ii. yum localinstall mysql57-community-release-el7-7.noarch.rpm
     iii. yum repolist enabled | grep "mysql.*-community.*"
     iv. yum install mysql-community-server
     v. yum-config-manager --disable mysql57-community
     vi. yum-config-manager --enable mysql56-community
     viii. service mysqld start
     ix. service mysqld status
     x. mysql --version
     xi. mysql -u root -p
