~2将”mysql-8.0.11-winx64.zip”解压到任何地方,如解压到c:\\java 下面

命令 bin\\mysql -u root -p  
Mysql:是自带的客户端,-u:root(用户名),-p(密码)![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzY5NDE0NA_size_16_color_FFFFFF_t_70 11]  
密码data目录下面主机名.err文件中,每台电脑,每次安装密码都不一样

出现以下界面表示连接成功,mysql数据库安装成功  
![在这里插入图片描述][20181114143323529.png]  
必须先重置密码;  
![在这里插入图片描述][20181114143335726.png]  
– 密码的过期策略:  
ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘123456’ PASSWORD EXPIRE NEVER;  
– mysql8.0加密有三种方式;本地(native),cache2(默认,navicate程序,都不能连接);  
ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql\_native\_password BY ‘123456’;  
重新登陆,使用新密码OK  
3 如何用idea 连接MySQL  
~1 在窗口界面有个Database  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzY5NDE0NA_size_16_color_FFFFFF_t_70 12]  
~2 点击 后 选择 MySQL

之后就成功了
