无法启动 MariaDB 数据库服务器MariaDB 服务器已关闭/超时

如何解决无法启动 MariaDB 数据库服务器MariaDB 服务器已关闭/超时

mysqld上面没有问题，只有mariadb报错 并且不会重启。我从一开始就安装了mysqld + mariadb，但是还是报错。 所有版本的最新版本都在 CentOS8 上

执行命令后出现此问题（附图）。 enter image description here

并且根据本站的说明，我给出了命令行： https://www.a2hosting.com/kb/developer-corner/mysql/reset-mysql-root-password

[root@server ~]# service mysqld status

更新：

sudo systemctl restart mariadb mariadb.service 的作业失败，因为 超时。请参阅“systemctl status mariadb.service”和 “journalctl -xe”了解详情。

my.cnf :

[mysqld]

query_cache_type=1
query_cache_size =32M
query_cache_limit=1M

解决方法

如果您同时运行 mysql 和 mariadb，则需要将它们的配置设置为使用不同的端口、套接字、数据目录、日志文件等。共享相同的数据文件是行不通的。

即使使用不同的数据，也确实不值得付出努力。在不同的服务器或虚拟机上运行它们。

我假设您的目标不是在一台服务器上运行这两种服务。

MariaDB 是 MySQL 的替代品，它们旨在无需大量配置即可在同一台服务器上运行。在大多数发行版中，它们共享有关配置和数据的路径。

除非您解释将两个服务并排运行的用例，否则我假设您的问题只是试图运行这两个服务。坚持一个，你就可以开始了。
