mac下brew安装mysql8.0.19

之前在MAC上安装MYSQL一般是用官方的直接解压安装或下载dmg安装包或者自己编译安装，今天尝试第四种方式brew安装。

1、先brew info mysql查看下版本信息：

2、brew install mysql直接安装：

3、启动MYSQL服务

mysql.server start

 

4、初始化配置mysql_secure_installation

5、连接

brew安装后MYSQL的配置文件my.cnf位置为：/usr/local/etc/my.cnf

常用命令：

启动：sudo mysql.server start
关闭：sudo mysql.server stop
重启：sudo mysql.server restart
连接：mysql -u root -p
开机启动：brew services start mysql

用Navicat Premium尝试连接刚安装的MYSQL服务报如下错误：

Authentication plugin 'caching_sha2_password' cannot be loaded: dlopen(/usr/local/mysql/lib/plugin/caching_sha2_password.so, 2): image not found

 

解决办法：

1、先修改my.cnf：

在[mysqld]块增加下面两行代码：

[caching_sha2_password]

default_authentication_plugin= mysql_native_password

重启MYSQL服务： sudo mysql.server restart

然后进入mysql:

$ mysql -u root -p         
Enter password:
