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

Question

我最近通过桌面升级了我的 CentOS 系统。错误！

我之前让 MariaDB、phpMyAdmin 工作得很好 - 但升级后他们停止了。

我疯狂地搜索并尝试遵循一些关于 MariaDB * MySQL 重新安装的教程，直到我来到这个：

http://centosforge.com/node/how-replace-mysql-mariadb-centos-6-include-mysql-uninstall-instructions-and-yum-install

我执行此命令以删除所有 MySQL：

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

然后尝试重新安装 MySQL：

如下 - 它崩溃并出现如下错误：

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

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest

如果我现在尝试安装 libssl.10，我会被要求安装 glibc 库。2.17 和 2.7。
其他讨论说要远离它们，因为这会爆炸我的系统。我尝试下载 2.17 并且它很大 - 解压缩需要很长时间。

有人可以帮我完全删除 MariaDB 并安装 MySQL - 这样我就不会在运行时出现上述错误并推送到 MariaDB：

yum install mysql-server mysql mysql-devel

有大量关于如何安装 MariaDB 的材料 - 但到目前为止我发现没有一个可以清楚地解释如何倒退到 MySQL。

您的系统上仍然有 MariaDB yum 存储库。只要你这样做，MariaDB 就会继续取代 MySQL。

要解决此问题，请删除 MariaDB 存储库。通过在目录中定位文件（它的名称可能类似于mariadb.repo）来执行此操作/etc/yum.repos.d。找到该文件后，您可以将其删除，或者您可以编辑该文件并更改enabled=1为enabled=0.
