如上述报错的话，加上user，并记录初始密码

mysqld –initialize –user=root –console

C:\WINDOWS\system32>mysqld --initialize --user=root --console

安装服务

登陆系统

如登陆不上，需要运行net stop mysql,

然后重新运行下mysqld –initialize –user=root –console

mysql -u root -p

C:\WINDOWS\system32>mysql -u root -p
Enter password: ************

修改密码

ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘fjdoe13232’; mysql执行语句一定要以;结尾。切记。

';
Query OK, 0 rows affected (0.11 sec)

常用命令

show databases;

mysql> show databases; +--------------------+
| Database | +--------------------+
| information_schema | | mysql | | performance_schema |
| sys | +--------------------+
4 rows in set (0.01 sec)
mysql>

create database 数据库;

mysql> create database ustest;
Query OK, 1 row affected (0.03 sec)
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |

mysql> use ustest;

以上是简单环境配置。
