Mac 下安裝 MySQL 還是很方便的, 總結來看有2個方法。
1、安裝
#官網下載好MySQL Mac 版安裝包，常規步驟安裝，安裝過程中會出現如下提示：
2019-03-24T18:27:31.043133Z 1 [Note] A temporary password is generated for root@localhost: TdfRm19!o0Xi
其中TdfRm19!o0Xi是初始密碼，最好先記住！
2、登陸
在終端機命令列登陸mysql:
$ mysql -u root -p # 输入上述密码即可
如果這一步驟提示: bash: mysql: command not found, 執行下面2個指令做個軟連線即可：
cd /usr/local/bin ln -fs /usr/local/mysql-8.0.11-macos10.13-x86_64/bin/mysql mysql
3、修改密碼
在MySQL8.0.4 以前，執行SET PASSWORD=PASSWORD('新密碼')即可。但新版不能這樣改了，因為密碼認證變了。具體步驟可參考 https://blog.csdn.net/yi247630676/article/details/80352655。
總所周知，Mac 可以利用homebrew 進行安裝管理，十分方便，如果沒有安裝homebrew, 可以點擊https://brew.sh/ 安裝。
下面是mysql 的安裝方式
$ brew install mysql # 安装指定版本： brew install mysql@1.1.1
接下來只要等待就可以了，出現下面文字後我們已經很清楚我們需要做什麼了：
==> mysql We've installed your MySQL database without a root password. To secure it run: mysql_secure_installation MySQL is configured to only allow connections from localhost by default To connect run: mysql -u root 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
按說明繼續執行，進行初始化操作：
$ myysql_secure_installation
初始化過程中會有很多問題，以下是具體問題部分，以註釋為解釋：
Would you like to setup VALIDATE PASSWORD component? Press y|Y for Yes, any other key for No: Y ## 回复y 需要密码8位以上，回复n 则不做限制 The password validation component is not available. Proceeding with the further steps without the component. Please set the password for root here. New password: ## 设置你的密码 Re-enter new password: ## 再次输入你的密码 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. Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y ## 是否移除匿名用户。考虑安全我选了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. Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y ## 是否允许远程连mysql 的 root。我用做本地调试，不是远程服务器，所以y了 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? (Press y|Y for Yes, any other key for No) : Y ## 是否y了删除test数据库，我选了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 ## 选y, 重新加载权限列表 Success. All done!
到此配置就結束了，下面我們啟動mysql 即可，記住以下指令：
$ mysql -u root -p ## 登陆 mysql $ brew services start mysql@5.7 ## 启动 mysql $ brew services stop mysql@5.7 ## 停止 mysql $ mysql.server start ## 启动 mysql(无后台服务)
