MySQL5.7.21安装与密码设置教程,具体如下

官方参考手册

1.解压MySQL 5.7.20安装包,如X:/MySQL/mysql-5.7.21-winx64。(是没有data和my.ini的)

 

2.配置mysql的环境变量,创建MYSQL_HOME,并且在Path添加上%MYSQL_HOME%/bin;

  

3,配置my.ini. 并把my.ini放到bin目录下(1.如果放在mysql-5.7.21-winx64 目录下,在下面执行net start mysql时可能无法启动MYSQL服务、2.不会自动生成data)

[client] default-character-set=utf8 [mysqld]#解压目录 如:D:/MySQL/mysql-5.7.21-winx64 basedir = %MYSQL_HOME% #解压目录 如:D:/MySQL/mysql-5.7.21-winx64/data datadir = %MYSQL_HOME%/data   port = 3306  default-character-set=utf8

4. 以管理员身份进入命令行(可在小娜搜索输入cmd找到),并进入X:/MySQL/mysql-5.7.21-winx64/bin目录下输入命令:mysqld --initialize-insecure (生成无密码的root用户) 后,在mysql-5.7.20-winx64 目录下就会出现data文件

5.再输入mysqld --install,如果出现Service successfully installed 说明注册成功了。

注意:如果此操作报错Install/Remove of the Service Denied!,建议使用管理员身份进入命令提示符


6.启动MySQL服务,命令:net start mysql

7.设置密码   mysqladmin -u root password 密码

8.修改密码方法如下 :接着输入mysql -uroot -p    由于之前登陆过,直接输入刚才设置密码(登录root第一次是免密码的直接回车进入到) MYSQL>

接着输入:update mysql.user set authentication_string=password('你想输入的密码') where user='root' and Host ='localhost';    然后接着再输入: flush privileges;


9.输入命令show databases;  查看数据表

MySQL常用的命令如下

List of all MySQL commands: Note that all text commands must be first on line and end with ';'(要以“;”结尾) ?   (/?) Synonym for `help'. clear  (/c) Clear the current input statement. connect (/r) Reconnect to the server.
