mysql - 我无法连接到我刚刚安装的 MySQL 服务器

Question

我已经在 Ubuntu 16.04 上安装了 MySQL :

sudo apt-get install mysql-client-5.7 mysql-server-5.7

要检查安装情况，我运行以下命令:

mysql --version

mysql  Ver 14.14 Distrib 5.7.19, for Linux (x86_64) using  EditLine wrapper

还有:

 systemctl status mysql.service

● mysql.service - MySQL Community Server

Oct 06 16:34:36 SV1080AP1105 systemd[1]: Started MySQL Community Server.

但是当我尝试连接时它不起作用!!!

sudo mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

Answer 1

试试这个:

    sudo grep 'temporary password' /var/log/mysqld.log

对于全新安装，MySQL 5.7 及以上版本会将临时密码保存在日志中。这可能会有所帮助。

然后使用密码，执行以下操作:

    sudo mysql -u root -p RETRIEVED_PASSWORD
