MySQL增加用户

在phpmyadmin创建超级用户生成的命令：

CREATE USER 'the_temp_admin'@'%'
IDENTIFIED VIA mysql_native_password USING '***';

GRANT ALL PRIVILEGES ON *.* TO 'the_temp_admin'@'%'
REQUIRE NONE
WITH GRANT OPTION
MAX_QUERIES_PER_HOUR 0
MAX_CONNECTIONS_PER_HOUR 0
MAX_UPDATES_PER_HOUR 0
MAX_USER_CONNECTIONS 0;

下面是可以在命令行中执行的命令，——在phpmyadmin中提示语法错误。

CREATE USER 'the_temp_admin2'@'%' IDENTIFIED BY 'the_password';
GRANT ALL PRIVILEGES ON *.* TO 'the_temp_admin2'@'%' WITH GRANT OPTION;

以下都是缺省行为，所以没有加到GRANT命令中：

REQUIRE NONE
MAX_QUERIES_PER_HOUR 0
MAX_CONNECTIONS_PER_HOUR 0
MAX_UPDATES_PER_HOUR 0
MAX_USER_CONNECTIONS 0;

创建只可以访问某数据库的account:

CREATE USER 'user_name'@'localhost' IDENTIFIED BY 'the_password';
CREATE USER 'user_name'@'%'         IDENTIFIED BY 'the_password';
GRANT ALL PRIVILEGES ON db_name.* TO 'user_name'@'localhost';
GRANT ALL PRIVILEGES ON db_name.* TO 'user_name'@'%';

设置password的两种方法：

CREATE USER 'the_user_name'@'localhost'
IDENTIFIED BY 'the_plain_text_password';
CREATE USER 'the_user_name'@'%'
IDENTIFIED BY 'the_plain_text_password';
CREATE USER 'the_user_name'@'localhost'
IDENTIFIED BY PASSWORD PASSWORD('the_plain_text_password');
CREATE USER 'the_user_name'@'%'
IDENTIFIED BY PASSWORD PASSWORD('the_plain_text_password');
