在Ubuntu上安装MySQL

Question

我试图在ubuntu16.04上安装MySQL。我看过这里的各种帖子和服务器故障，试图解决这个问题，但它仍然存在。

我使用以下方法安装了MySQL：

sudo apt-get install mysql-server

然后，在设置根密码之后，安装就挂起了：

Renaming removed key_buffer and myisam-recover options (if present)

我已经清除和重新启动了，没有运气。

摘自启动板：

[Workaround Option 1/3]

To reset your MySQL configuration back to defaults,
type "sudo update-alternatives --remove my.cnf /etc/mysql/my.cnf.migrated" after the upgrade.
Then use "sudo service mysql start" to start the MySQL daemon
and "sudo apt-get -f install" to recover your system packaging state.
