MySQL-mysql_upgrade-发生错误：无法设置服务器变量

我在官方docker映像中运行MySQL 5.7.11。

当我想要升级时，出现以下错误：

mysql_upgrade -uroot -p
password:
Error occurred: Cannot setup server variables.

我四处搜寻，没有发现任何提示。我试着跑了--verbose，但没有运气。

供参考，这是我启动数据库时的日志：

我找到了解决方法！

停止您的数据库。然后开始：

mysqld --skip-grant-tables &

然后，我终于可以进行升级了：

mysql_upgrade

从5.7.x升级到5.7.15时，使用apt-get但不是在Docker映像内，而是在基本的Ubuntu 16.04 EC2实例上，我遇到了类似的问题。

我设法通过.mylogin.cnf为Linux根用户帐户设置一个文件来摆脱过去，以便它无需提供用户名和密码即可登录，然后mysql_upgrade在登录到根帐户时运行该命令。

这样就可以执行所需的系统表升级，然后我能够apt-get upgrade毫无问题地完成命令。

在我身上，我不得不

mv /var/lib/mysql /var/lib/mysql.bak

复制一个只有基本mysql数据库的/ var / lib / mysql文件夹。我刚好在/ var / lib / mysql-new中存储了一个

mv /var/lib/mysql-new /var/lib/mysql
service mysql restart

apt-get install -f

它经历并升级了mysql数据库，然后您可以：

 mv /var/lib/mysql /var/lib/mysql-new
 mv /var/lib/mysql.bak /var/lib/mysql
 service mysql restart

为我工作。我尝试了很多其他建议，包括清除，删除所有内容并重新开始，使用apparmor等，但这是对我有用的唯一方法。

就我而言，相同的问题通过以下方式解决了：

$ mysql_upgrade db_username@db_host -p
