Question

我正在尝试安装maria db并遇到以下问题。

[root@localhost ~]# service mysqld start
Redirecting to /bin/systemctl start  mysqld.service
Job for mariadb.service failed. See 'systemctl status mariadb.service' and 'journalctl -xn' for details.

我尝试了系统状态mariadb.service＆＃39;和＆＃39; journalctl -xn＆＃39;并遵循细节。

[root@localhost ~]# systemctl status mariadb.service

任何人都可以帮忙吗？

我尝试了多次卸载和安装，但收到了同样的错误。

提前致谢。

Answer 1

我解决了如下：

安装后

HashMap

有了这个，我可以解决。

Answer 2

大多数情况下，如果系统日志（journalctl）没有显示问题所在，则MariaDB错误日志（位于/var/lib/mysql/localhost.localdomain.err中）会显示。查看该文件通常可以发现问题所在。

大多数常见的错误在重新安装后不会消失，这意味着您的数据目录（默认为/var/lib/mysql/）已损坏，并且需要使用mysql_install_db重新安装数据库。为了确保您执行的是全新安装，请删除数据目录中的所有文件，然后运行sudo mysql_install_db --user=mysql。

Answer 3

所有通过网络搜索来到这里的人的快速更新。

在Debian 9-> Debian 10（Buster）就地服务器升级之后，我收到一条“无法启动”消息，经过一番挖掘，我发现/etc/mysql/my.cnf中的以下行需要更新：

发件人：

[mysqld]
: (other stuff)
:
innodb_large_prefix

收件人：

[mysqld]
: (other stuff)
:
innodb_large_prefix = "ON"

线索是/var/log/mysql/error.log中的以下几行

2020-06-06 16:41:24 0 [ERROR] /usr/sbin/mysqld: option '--innodb-large-prefix' requires an argument
2020-06-06 16:41:24 0 [ERROR] Parsing options for plugin 'InnoDB' failed.
