We've installed your MySQL database without a root password. To secure it run:

MySQL is configured to only allow connections from localhost by default
To connect run:

To start mysql now and restart at login:
brew services start mysql
==> redis
To start redis now and restart at login:
brew services start redis
2 启动
MySQL分为服务端和客户端,刚才安装好的是服务端,客户端不需额外安装
启动服务端
在一个命令行窗口
➜ ~ brew services start mysql
==> Successfully started `mysql` (label: homebrew.mxcl.mysql
MySQL服务端就启动了,它是一个在后台运行的项目
启动客户端
在另一个命令行窗口
➜ ~ mysql -u root
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 8

连接成功后,使用show database
显示当前服务器的所有数据库,系统会自动创建一些数据库?因为从我下载以后没有进行过多余的操作
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sys |
+--------------------+
4 rows in set (0.00 sec)
mysql>
提示:一定是先启动服务端再启动客户端,否则提示
➜ ~ mysql -u root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
3 关闭
关闭服务端
➜ ~ brew services stop mysql
Stopping `mysql`... (might take a while)
==> Successfully stopped `mysql` (label: homebrew.mxcl.mysql)
➜ ~
关闭客户端不需要特殊命令
直接control+Z暴力杀死进程退出即可
