==> Pouring mysql-5.7.17.sierra.bottle.tar.gz
==> Using the sandbox
==> /usr/local/Cellar/mysql/5.7.17/bin/mysqld --initialize-insecure --user=liangze --basedir=/usr/local/Cellar/mysql/5.7.17 --datadir=/usr/local/var/mysql --t
==> Caveats
We've installed your MySQL database without a root password. To secure it run:
mysql_secure_installation
To connect run:
mysql -uroot
To have launchd start mysql now and restart at login:
brew services start mysql
Or, if you don't want/need a background service you can just run:
mysql.server start
==> Summary
/usr/local/Cellar/mysql/5.7.17: 14,226 files, 444.4M
安装成功之后，我们需要先启动 mysql 服务
mysql.server start
然后再运行
mysql_secure_installation
运行完成之后，显示：

VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?

By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
// 这里删除默认无密码用户
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
// 禁止远程root登录，我选的是不禁止。因为我的mac上的数据库不会放到公网上，也不会存什么敏感数据
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : no
... skipping.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
// 这里删除默认自带的test数据库
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.
All done!
最后我们就可以进行登录了。
