It is very convenient to install MySQL under Mac. In summary, there are two methods.
Method 1: Install with dmg image
1. Installation
Download the MySQL Mac version installation package from the official website and install it with the usual steps. The following prompt will appear during the installation process:
2019-03-24T18:27:31.043133Z 1 [Note] A temporary password is generated for root@localhost: TdfRm19!o0Xi
TdfRm19!o0Xi is the initial password, it’s best to remember it first!
2. Log in
Log in to mysql on the terminal command line:
$ mysql -u root -p # 输入上述密码即可
If this step prompts: bash: mysql: command not found, execute the following Just use 2 commands to make a soft connection:
cd /usr/local/bin ln -fs /usr/local/mysql-8.0.11-macos10.13-x86_64/bin/mysql mysql
3. Change the password
Before MySQL8.0.4, execute SET PASSWORD=PASSWORD('new password') That’s it. But the new version cannot be changed like this because the password authentication has changed. For specific steps, please refer to https://blog.csdn.net/yi247630676/article/details/80352655.
Method 2: Use Homebrew to install
As we all know, Mac can use homebrew for installation and management, which is very convenient. If homebrew is not installed, you can click https://brew.sh/ to install it. .
The following is the installation method of mysql
$ brew install mysql # 安装指定版本： brew install mysql@1.1.1
The next step is just to wait. After the following text appears, we already know what we need to do:
==> 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
Follow the instructions Continue execution and perform initialization operations:
$ myysql_secure_installation
There will be many problems during the initialization process. The following are specific problems, explained with comments:
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!
The configuration is over at this point. Let’s start mysql is enough, remember the following commands:
$ 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)
