在Ubuntu 16.04上重新安装MySQL 5.7服务器的问题 [英] Issues on reinstalling MySQL 5.7 server on Ubuntu 16.04

问题描述

我的服务器在Ubuntu 16.04上运行 我的MySQL配置有问题，因此我决定清理并重新安装MySQL服务器.

My server is running on Ubuntu 16.04 I hade some issue with my MySQL configuration, so I've decided to clean up and reinstall the MySQL server.

此命令后:

sudo apt-get install mysql-server

这是我在流程结束时得到的:

This is what i got at the end of the process:

update-alternatives: using /etc/mysql/mysql.cnf to provide /etc/mysql/my.cnf (my.cnf) in auto mode
Renaming removed key_buffer and myisam-recover options (if present)

我尝试启动MySQL并运行systemctl status mysql.service给出了这一点:

I try to start the MySQL and running systemctl status mysql.service gave this:

● mysql.service - MySQL Community Server

当我尝试使用mysql -u root -p

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

推荐答案

您可能希望尝试从源代码安装，以便您可以查明是什么导致了问题.

You may want to try installing from source so you can try to pinpoint what is exactly causing the problem.

首先使用以下命令删除所有部分安装的mysql软件包:

First remove all partially installed mysql packages using:

$ sudo apt-get remove --purge mysql\*

然后按照本指南进行操作:

Then follow this guide:
