1、吐槽
MySQL官方下载的可以正常安装MySQL Server及其他相关组件，但是到配置项configuration的时候竟然没有下一步选择了！！Orz- 只好选择用格式安装了
2、解压
- 将
zip文件下载后解压到C:/Program Files/MySQL/MySQL Server 8.0/文件夹 - 文件夹下新建
my.ini文件 - 配置
my.ini文件 - 以管理员身份启动
cmd窗口
cd /d C:/Program Files/MySQL/MySQL Server 8.0/bin复制代码
#将以前的错误安装删除，否则会提示已经安装 mysqld -remove #初始化，记得记住 localhost 的初始化的密码 mysqld --initialize --user=mysql --console复制代码
#注册成服务 mysqld install复制代码
#启动服务 net start mysql复制代码
#登陆 mysql> mysql -u root -p #变更root密码 mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'newpass'; #解决用户自定义函数报错 mysql>set global log_bin_trust_function_creators=1;复制代码
#解决方式一 mysql>set global log_bin_trust_function_creators=1; #解决方式二 系统启动时 --log-bin-trust-function-creators=1 #解决方式三 在my.ini(linux下为my.conf)文件中 [mysqld] 标记后加一行内容为 log-bin-trust-function-creators=1复制代码
3、my.ini配置
