从CentOS 7或RHEL 7完全删除MariaDB或MySQL [英] Completely remove MariaDB or MySQL from CentOS 7 or RHEL 7

问题描述

我在CentOS 7上安装了MariaDB，但是我在某些配置上遇到了一些问题，现在它被完全错误地配置了.

I installed MariaDB on CentOS 7 but I had some problems with some configuration, now it is completely misconfigured.

因此，我想用"yum remove mariadb mariadb-server"删除MariaDB，然后再用"yum install mariadb mariadb-server"重新安装它.

Thus, I wanted to remove the MariaDB with "yum remove mariadb mariadb-server", after that I reinstalled it with "yum install mariadb mariadb-server".

不幸的是，配置仍然存在.似乎yum remove并不会删除所有MariaDB配置文件.

Unfortunately, the configuration remains. It seems as if yum remove don’t delete all MariaDB Config-Files.

如何从CentOS 7中完全删除MariaDB?

How can I remove MariaDB completely from CentOS 7?

推荐答案

这些步骤适用于CentOS 6.5，因此它们也应适用于CentOS 7:

These steps are working on CentOS 6.5 so they should work on CentOS 7 too:

1. yum remove mariadb mariadb-server
2. rm -rf /var/lib/mysql如果/etc/my.cnf 中的数据目录指向其他目录，请删除该目录，而不是/var/lib/mysql
3. rm /etc/my.cnf
4. 可选步骤:rm ~/.my.cnf
5. yum install mariadb mariadb-server

1. yum remove mariadb mariadb-server
2. rm -rf /var/lib/mysql If your datadir in /etc/my.cnf points to a different directory, remove that directory instead of /var/lib/mysql
3. rm /etc/my.cnf
4. Optional step: rm ~/.my.cnf
5. yum install mariadb mariadb-server

[ EDIT ]-在CentOS 7上更新MariaDB 10.1

[EDIT] - Update for MariaDB 10.1 on CentOS 7

以上步骤适用于CentOS 6.5和MariaDB10.

The steps above worked for CentOS 6.5 and MariaDB 10.

我刚刚在CentOS 7上安装了MariaDB 10.1，其中某些步骤略有不同.

I've just installed MariaDB 10.1 on CentOS 7 and some of the steps are slightly different.

第1步将变为:

yum remove MariaDB-server MariaDB-client

第5步将变为:

yum install MariaDB-server MariaDB-client

其他步骤保持不变.
