全新安装后无法像其他旧 MySQL 版本那样使用 root ID 和空/无密码登录到 MySQL 数据库

Cannot login to MySQL database after fresh install with root ID and empty/no password like other older MySQL versions do

推荐答案

在linux上全新安装MySQL-community-server 5.7后，需要从/var/log/mysqld.log中找到临时密码才能登录作为根.

After you installed MySQL-community-server 5.7 from fresh on linux, you will need to find the temporary password from /var/log/mysqld.log to login as root.
