mac 通过brew 安装的mysql启动失败解决方案_weixin_33681778的博客-CSDN博客

当我们安装好MySQL后，在终端输入mysql命令，发现并不能看到自己安装的数据库，这是因为你没有配置环境变量。

在os系统中安装MySQL数据库默认保存在/usr/local/mysql

那么我们应该如何配置环境变量呢？

1、打开terminal，输入：sudo su 回车进入系统管理员管理目录（当然你要输入你的用户密码才能进入）

2、输入命令：vim /etc/profile 接着就进入到vim编辑界面

3、在vim编辑界面，按i进入编辑状态，接着，就可以增加路径名称，输入命令：

export PATH=$PATH:/usr/local/mysql/bin

修正本机安装了oh-my-zsh

# php
#export PATH="$(brew --prefix /Cellar/php/7.4.11)/bin:$PATH"
# export PATH="/usr/local/Cellar/php/7.4.11/bin:$PATH"
export PATH="$(brew --prefix php@7.4)/bin:$PATH"

# maven
# export PATH="/usr/local/opt/maven@3.2/bin:$PATH"
export PATH="$(brew --prefix maven@3.2)/bin:$PATH"

# mysql echo "$(brew --prefix mysql@5.7)"
export PATH="$(brew --prefix mysql@5.7)/bin:$PATH"

Securing the MySQL server deployment.

Connecting to MySQL using a blank password.

VALIDATE PASSWORD PLUGIN 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 plugin?

Press y|Y for Yes, any other key for No: y

There are three levels of password validation policy:

LOW    Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0
Please set the password for root here.

New password: 

Re-enter new password: 

Estimated strength of the password: 50 
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
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
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.


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!
