Mac 下装置 MySQL 照样很轻易的, 总结来看有2个要领。
要领一：用dmg镜像装置
1、装置
官网下载好 MySQL Mac 版装置包，通例步骤装置，装置历程当中会涌现以下提醒：
2019-03-24T18:27:31.043133Z 1 [Note] A temporary password is generated for root@localhost: TdfRm19!o0Xi
个中TdfRm19!o0Xi是初始暗码，最好先记着！
2、上岸
在终端敕令行 上岸mysql:
$ mysql -u root -p # 输入上述暗码即可
假如这一步提醒: bash: mysql: command not found, 实行下面2个敕令做个软衔接即可：
cd /usr/local/bin ln -fs /usr/local/mysql-8.0.11-macos10.13-x86_64/bin/mysql mysql
3、修正暗码
在 MySQL8.0.4 之前，实行 SET PASSWORD=PASSWORD('新暗码') 即可。但新版本不能如许改了，由于暗码认证变了。具体步骤能够参考 https://blog.csdn.net/yi247630676/article/details/80352655。
要领二：用 Homebrew 举行装置
总所周知，Mac 能够应用 homebrew 举行装置治理，非常轻易，假如没有装置 homebrew, 能够点击 https://brew.sh/ 装置。
下面是 mysql 的装置体式格局
$ brew install mysql # 装置指定版本： brew install mysql@1.1.1
接下来只需守候就能够了，涌现下面文字后我们已很清晰我们须要做什么了：
==> 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
按申明继承实行，举行初始化操纵：
$ myysql_secure_installation
初始化历程当中会有许多题目，以下是具体题目部份，以诠释为诠释：
Would you like to setup VALIDATE PASSWORD component? Press y|Y for Yes, any other key for No: Y ## 复兴y 须要暗码8位以上，复兴n 则不做限定 The password validation component is not available. Proceeding with the further steps without the component. Please set the password for root here. New password: ## 设置你的暗码 Re-enter new password: ## 再次输入你的暗码 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 ## 是不是移除匿名用户。斟酌平安我选了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 ## 是不是许可长途连mysql 的 root。我用做当地调试，不是长途效劳器，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 ## 是不是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, 从新加载权限列表 Success. All done!
到此设置就完毕了，下面我们启动 mysql 即可，记着以下敕令：
$ mysql -u root -p ## 上岸 mysql $ brew services start mysql@5.7 ## 启动 mysql $ brew services stop mysql@5.7 ## 住手 mysql $ mysql.server start ## 启动 mysql(无后台效劳)
