安装mysql服务 

#mysqld --install 服务名

mysqld --install mysql

登录

mysql -uroot -pS!kllE;2eNO

如果提示密码错误或忘记密码需要修改密码

C:Windowssystem32>mysql -uroot -p
Enter password: ***********
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

在my.ini中[mysqld] 添加 skip-grant-tables，表示跳过权限验证

[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[mysqld]
#设置3306端口
port = 3306
# 设置mysql的安装目录
basedir=D:mysql-5.7.29-winx64mysql-5.7.29-winx64
# 设置mysql数据库的数据的存放目录
datadir=D:mysql-5.7.29-winx64mysql-5.7.29-winx64data
# 允许最大连接数
max_connections=200
# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB

#跳过登录密码验证
skip-grant-tables

重启服务

net stop mysql

net start mysql

mysql -uroot -p 直接回车登录

重新设置密码：set password for root@localhost=password('root');

如果报一下错误，则先刷新权限执行 flush privileges; 之后在执行 set password for root@localhost=password("新密码");

mysql> set password for root@localhost=password('root');
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

删除my.ini中最后一行添加 skip-grant-tables，并重启服务

重新登录

mysql -uroot -proot

C:Windowssystem32>mysql -uroot -proot
