如何卸载 MariaDB 并重新安装 MySQL？MySQL 安装变成 MariaDB 安装

我最近通过桌面升级了我的 CentOS 系统。错误！

之前我的 MariaDB 和 phpMyAdmin 运行正常 - 但升级后它们就停止了。

我疯狂地谷歌搜索，试图找到一些教程关于 MariaDB MySQL 重新安装，直到我看到这个：

我执行了这个命令来删除所有 MySQL：

yum remove mysql-server mysql-libs mysql-devel mysql*

然后尝试重新安装 MySQL：

如下所示 - 它崩溃并出现以下错误：

*****************************************************************
[root@localhost ~]# yum install mysql-server mysql mysql-devel

[root@localhost ~]

如果我现在尝试安装 libssl.10，系统会要求我安装 glibc 库。2.17 和 2.7。
其他讨论说要避开它们，因为这会使我的系统崩溃。我尝试下载 2.17，但它非常大 - 解压需要很长时间。

有人可以帮我完全删除 MariaDB 并安装 MySQL - 这样当我运行时就不会出现上述错误并推送到 MariaDB：

yum install mysql-server mysql mysql-devel

关于如何安装 MariaDB 的资料有很多 - 但到目前为止我发现没有一个能清楚地解释如何返回到 MySQL。

答案1

您的系统上仍然有 MariaDB yum 存储库。只要您这样做，MariaDB 将继续取代 MySQL。

要解决此问题，请删除 MariaDB 存储库。通过在目录中找到文件（可能命名为mariadb.repo）来执行此操作/etc/yum.repos.d。找到文件后，您可以将其删除，也可以编辑文件并更改enabled=1为enabled=0。

答案2

如果您必须有 mysql，您需要添加 mysql-community repo sudo rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm，然后您可以像平常一样安装 MySQLl。

答案3

在 Ubuntu 上你需要删除dbconfig-mysql并安装dbconfig-no-thanks
