This article brings you a detailed explanation of the steps to build a MySQL environment under Mac. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

It is very convenient to install MySQL on 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 will appear during the installation process. Tip:

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 is 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

Then just 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 command:

$ 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)
