Mysql 5.7.14 使用常见问题汇总(推荐)

1、解压

2、在目录D:\Program Files\mysql-5.7.14-winx64下复制my-default.ini,放在与其相同目录下,名称显示为my.ini;

3、编辑my.ini

# For advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the# *** default location during install, and will be replaced if you# *** upgrade to a newer version of MySQL.[client]default-character-set=utf8[mysqld]# Remove leading # and set to the amount of RAM for the most important data# cache in MySQL.

4、在解压目录D:\Program Files\mysql-5.7.14-winx64下新建data文件(不用在文件夹做其他操作)

5、以管理员身份进入cmd界面(必须是管理员)

6、切换至mysql解压目录\bin下,初始化data目录

输入命令:mysqld --initialize-insecure (生成无密码的root用户)

或:mysqld --initialize(生成带随机密码的root用户)

7、初始化完成后启动mysql服务

输入命令:net start mysql

8、开始使用mysql

输入命令:mysql -u root -p

9、停止mysql服务

输入命令:net stop mysql

10、忘记root密码后如何登录

  101、 关闭正在运行的MySQL服务。

  10.2、 打开DOS窗口,转到mysql\bin目录。

  10.3、输入mysqld --skip-grant-tables 回车。--skip-grant-tables 的意思是启动MySQL服务的时候跳过权限表认证。

  10.4、再开一个DOS窗口(因为刚才那个DOS窗口已经不能动了),转到mysql\bin目录。

  10.5、输入mysql回车,如果成功,将出现MySQL提示符 >。

  10.6、连接权限数据库: use mysql; 。

  10.7、改密码:update user set password=password("123") where user="root";(别忘了最后加分号) 。

  10.8、刷新权限(必须步骤):flush privileges; 。

  10.9、 退出 quit。

  10.10、注销系统,再进入,使用用户名root和刚才设置的新密码123登录。

11、修改root用户密码

5.7版本以前:

update user set authentication_string =password( 'root') where user = 'root;

5.7版本以后:

update user set password=password( 'root') where user = 'root;
