    MySQL5.7

    CHARACTER SET utf8 COLLATE utf8_general_ci

    use mysql;
    CREATE USER 'reader'@'%' IDENTIFIED BY '123456';
    grant all privileges on mall.* to 'reader'@'%';
    flush privileges;
    
    

    进入mysql
    切换到use表
    更新host为%
    执行修改

    mysql -uroot -p   
    psaaword:
    use mysql;
     update user set host = '%' where user = 'root';
    flush privileges;
    

    [client]

    default-character-set=utf8

    [mysqld]
    default-storage-engine=INNODB
    character-set-server=utf8
    collation-server=utf8_general_ci
    lower_case_table_names=1

    grant all privileges on guoya_vitual_mall.* to 'test'@'%' identified by '123456..';

    grant all privileges on guoya_vitual_mall.* to 'test1'@'%' identified by '123456';

    安装MySQL

    sudo mysql -u root #使用root用户权限登录mysql

    SELECT User,Host FROM mysql.user; #查看用户与host信息
    +------------------+-----------+
    | User | Host |
    +------------------+-----------+
    | debian-sys-maint | localhost |
    | mysql.session | localhost |
    | mysql.sys | localhost |
    | root | localhost |
    +------------------+-----------+
    4 rows in set (0.00 sec)

    DROP USER 'root'@'localhost'; #删除root账号
    Query OK, 0 rows affected (0.00 sec)

    CREATE USER 'root'@'%' IDENTIFIED BY '****'; #添加root账户并设置登录密码,'****'符号内为密码
    Query OK, 0 rows affected (0.00 sec)

    4.为root用户授权,使其具有可以创建修改数据库等的权限
    GRANT ALL PRIVILEGES ON . TO 'root'@'%' WITH GRANT OPTION;
    Query OK, 0 rows affected (0.00 sec)
    CREATE USER 'test'@'%' IDENTIFIED BY '123456..';
    create database guoya_teach_test;
    FLUSH PRIVILEGES; #重新加载权限
    Query OK, 0 rows affected (0.00 sec)

    为用户授权

    授权格式:grant 权限 on 数据库.* to 用户名@登录主机 identified by "密码";

    2.1 登录MYSQL(有ROOT权限),这里以ROOT身份登录:

    @>mysql -u root -p

    @>密码

    2.2 首先为用户创建一个数据库(testDB):

    mysql>create database testDB;

    2.3 授权test用户拥有testDB数据库的所有权限(某个数据库的所有权限):

    mysql>grant all privileges on testDB.* to test@localhost identified by '1234';
      mysql>flush privileges;//刷新系统权限表

    格式:grant 权限 on 数据库.* to 用户名@登录主机 identified by "密码";

    2.4 如果想指定部分权限给一用户,可以这样来写:

    mysql>grant select,update on testDB.* to test@localhost identified by '1234';

    mysql>flush privileges; //刷新系统权限表

    2.5 授权test用户拥有所有数据库的某些权限:

    mysql>grant select,delete,update,create,drop on . to test@"%" identified by "1234";

     //test用户对所有数据库都有select,delete,update,create,drop 权限。
    

    //@"%" 表示对所有非本地主机授权,不包括localhost。(localhost地址设为127.0.0.1,如果设为真实的本地地址,不知道是否可以,没有验证。)

    //对localhost授权:加上一句grant all privileges on testDB.* to test@localhost identified by '1234';即可。
