Answer 1

这个是我最新并且一直推崇的方法：
1、安装：sunyichaodeMacBook-Pro:~ sunyichao$ brew install mysql
2、开启mysql：mysql.server start
2、使用mysql的配置脚本：/usr/local/opt/mysql/bin/mysql_secure_installation //mysql 提供的配置向导
启动这个脚本后，即可根据如下命令提示进行初始化设置

sunyichaodeMacBook-Pro:~ sunyichao$ /usr/local/opt/mysql/bin/mysql_secure_installation   //mysql 提供的配置向导
Securing the MySQL server deployment.
Connecting to MySQL using a blank password.
VALIDATE PASSWORD PLUGIN can be used to test passwordsand 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?

Press y|Y for Yes, any other key for No: k //是否采用mysql密码安全检测插件（这里作为演示选择否，密码检查插件要求密码复杂程度高，大小写字母+数字+字符等）
Please set the password for root here. // 首次使用自带配置脚本，设置root密码

New password:

Re-enter new password:

By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for 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.    
Remove anonymous users? [Y/n] Y //是否删除匿名用户
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] Y //是否禁止远程登录
 ... Success!

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.

Remove test database and access to it? [Y/n] Y //删除测试数据库，并登录
 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? [Y/n] Y//重新载入权限表
 ... Success!

All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!

Cleaning up...

1. brew install mysql (安装)

2. 添加修改mysql配置

   mysqld --help --verbose | more (查看帮助, 按空格下翻)

   你会看到开始的这一行(表示配置文件默认读取顺序)

   Default options are read from the following files in the given order:
   /etc/my.cnf /etc/mysql/my.cnf /usr/local/etc/my.cnf ~/.my.cnf

   通常这些位置是没有配置文件的, 所以要自己建一个

   ls $(brew --prefix mysql)/support-files/my-* (用这个可以找到样例.cnf)
   cp /usr/local/opt/mysql/support-files/my-default.cnf /etc/my.cnf (拷贝到第一个默认读取目录)

   按需修改my.cnf

3. brew services start mysql (启动)

4. brew services stop mysql (停止)

Answer 3

现在回答是不是有点晚了。
前几天我也在mac下安装 mysql.

mysql 数据库 5.7.5 前后的版本有差异。
以前的版本会在安装的时候要求输入密码。
5.7.6 版本会在安装的时候随机生成一个密码，用图形界面化安装的时候会显示密码，而用 brew install mysql命令安装的话，就不会显示密码了。
这个时候就得用其他办法就解决，否则会报错：

解决方法如官网所示：
http://dev.mysql.com/doc/refman/5.7/en/r...

图省事的话，可以直接用图形界面安装，之后再用 ALTER USER 来更改密码。

Answer 4

我用brew安装mysql的时候为什么没配置直接就能用了（除了配置用户名和密码）？

Answer 5

@子晓_believe ，我用完之后，发现本地的主机名改成了bogon是咋回事儿呀？

Answer 6

5.7.11之后密码要求更加严格了。可以参照下面的方式配置
