安装msyql@5.7

brew install mysql@5.7

# 安装成功后，会看到这样的提示
/usr/local/Cellar/mysql/5.7.9/bin/mysqld --initialize-insecure --user=comet
==> Caveats
We've installed your MySQL database without a root password. To secure it run:
    mysql_secure_installation

可以看到brew在安装的时候已经初始过mysql了(不用再像网上说的再执行mysql_install_db命令)，且当前没有密码于是我按照它的提示，执行命令：

mysql_secure_installation

按照提示设置密码即可

配置密码
