安装应用管理工具homebrew
homebrew是mac下的一款应用管理工具，类似于npm或gem等包管理工具，常用的工具都可以在这里找到。
使用它，你可以方便的一键安装、卸载、升级各种工具，强烈建议使用。
后面的步骤完全依赖它。
打开终端，在终端中运行如下安装命令，记得开启阿里郎的加速哦。（加速后等待15秒左右后开始执行如下命令哦）
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
安装超时可以尝试：
/usr/bin/ruby -e \
"$(curl -fsSL https://raw.github.cnpmjs.org/Homebrew/install/master/install)"
最新安装可以参考 官网： http://brew.sh
安装完记得更新brew仓库
brew update
使用brew安装软件（MySQL）
qiyibaba@B-92TNLVDL-1650 ~ brew install mysql
......
==> 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 -uroot
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
qiyibaba@B-92TNLVDL-1650 ~ cd /usr/local/Cellar/mysql/8.0.19/bin/
qiyibaba@B-92TNLVDL-1650 /usr/local/Cellar/mysql/8.0.19/bin ./mysql.server start
Starting MySQL
. SUCCESS!
qiyibaba@B-92TNLVDL-1650 /usr/local/Cellar/mysql/8.0.19/bin ./mysql_secure_installation
Securing the MySQL server deployment.
Connecting to MySQL using a blank password.
VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?
# 设置复杂密码：root123
Press y|Y for Yes, any other key for No: n
Please set the password for root here.
New password:
Re-enter new password:
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.
# 移除不用密码的那个账户
Remove anonymous users? (Press y|Y for Yes, any other key for No) : 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) : n
... skipping.
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.
# 允许远程登录
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : 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
Success.
All done!
