相关疑难解决方法(0)

我的当地环境是:

• 新鲜的Ubuntu 16.04
• 用PHP 7

• 安装MySQL 5.7

  sudo apt-get install mysql-common mysql-server
  

  Run Code Online (Sandbox Code Playgroud)

当我尝试登录MySQL(通过CLI)时:

mysql -u root -p

我遇到了一个包含3个步骤的循环问题.

1)首先是一些套接字问题

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

解决方案:重启PC.

这导致了另一个错误:

2)访问被拒绝

ERROR 1698 (28000): Access denied for user 'root'@'localhost'.

可能的问题？"root"用户的密码错误!

解决方案:使用本教程重置root密码.

使用正确的密码和工作套接字,会出现上一个错误.

3)auth插件不正确

mysql "ERROR 1524 (HY000): Plugin 'unix_socket' is not loaded"

在这里,我停下来或以某种方式得到了1).

我使用EditLine包装器安装了Mysql Ver 14.14 Distrib 5.7.9 for Linux(x86_64) On CentOS Linux 7.1.1503版

我使用此命令更改了root密码:

alter user 'root'@'localhost' identified by 'XXXXXXX';  
flush privileges;

重新登录后

[root@server ~]# mysql -u root -p
Enter password: 

ERROR 1524(HY000):未加载插件'*A6074285732753D325C55AD74E7517CF442C1A81'

我有以下错误：
