无法在 mariadb 服务器中使用 mysql，没有明确的原因

无法在 mariadb 服务器中使用 mysql，没有明确的原因

如果我只是输入 mysql -u root -p 并输入我的密码，我会进入我的数据库，但现在每次我说 mysql 和任何类似此输出的选项时，我仍然会收到一条消息

root@Dodge:~# mysql
Usage: /etc/init.d/mysql start|stop|restart|reload|force-reload|status
root@Dodge:~# mysql -u root
Usage: /etc/init.d/mysql start|stop|restart|reload|force-reload|status
root@Dodge:~# mysql -u root -p
Usage: /etc/init.d/mysql start|stop|restart|reload|force-reload|status

此消息意味着该服务未运行，对吗？但是当我运行状态时我得到服务处于活动状态

root@Dodge:~# systemctl status mysql

是活跃的所以为什么还给我

用法：/etc/init.d/mysql start|stop|restart|reload|force-reload|status

我尝试卸载每个 Thin 并重新安装它并安全安装并更新我的系统 - 我使用基于 debian 的 kali-linux 多年，没有任何问题。

当我运行 mysql status 时，我也会在底部看到此日志

which mysql返回/etc/init.d/mysql。之所以如此，是因为/etc/init.d它位于您的 PATH 之前，它具有在您键入时/usr/bin执行的效果。/etc/init.d/mysqlmysql

您需要确保 mysql 客户端的位置位于/etc/init.dPATH 之前。或者/etc/init.d从路径中删除；我看不出它存在的任何原因。此外，要使此更改永久生效，您需要更改配置文件或 bashrc 文件中的 PATH 设置。

如果您有理由不更改 PATH 变量，则需要通过提供完整路径名来启动 mysql 客户端：/usr/bin/mysql。
