Question

有没有办法创建一个新的MySQL数据库，一个新的MySQL用户，并使用PHP为新数据库赋予新的用户权限？

Answer 1

你可以这样做：

mysql_connect('localhost','user',password);
mysql_query("CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';");
mysql_query("GRANT ALL ON db1.* TO 'username'@'localhost'");
mysql_query("CREATE DATABASE newdatabase");
mysql_close();

您可以查看GRANT和CREATE USER

上的MySQL文档

Answer 2

是的，因为所有这些操作都可以通过常规SQL查询来执行。

但是，我不会使用root用户的数据库连接运行PHP脚本。

Answer 3

如果您在CPanel上托管项目，则mysql_query方法将无法创建数据库，用户和授予权限。

您必须使用XML Api for CPanel。

<?php
include("xmlapi.php");

$db_host = 'yourdomain.com'; 
$cpaneluser = 'your cpanel username';
$cpanelpass = 'your cpanel password'; 

$databasename = 'testdb';
$databaseuser = 'test'; // Warning: in most of cases this can't be longer than 8 characters
$databasepass = 'dbpass'; // Warning: be sure the password is strong enough, else the CPanel will reject it

$xmlapi = new xmlapi($db_host);    
$xmlapi->password_auth("".$cpaneluser."","".$cpanelpass."");    
$xmlapi->set_port(2082);
$xmlapi->set_debug(1);//output actions in the error log 1 for true and 0 false  
$xmlapi->set_output('array');//set this for browser output  
//create database    
$createdb = $xmlapi->api1_query($cpaneluser, "Mysql", "adddb", array($databasename));   
//create user 
$usr = $xmlapi->api1_query($cpaneluser, "Mysql", "adduser", array($databaseuser, $databasepass));   
 //add user 
$addusr = $xmlapi->api1_query($cpaneluser, "Mysql", "adduserdb", array("".$cpaneluser."_".$databasename."", "".$cpaneluser."_".$databaseuser."", 'all'));
?>

从here下载xmlapi.php，或者只是在Google上搜索它。

这对我来说非常有用。

Answer 4

我建议你使用phpmyadmin。

你需要做的步骤：

打开phpmyadmin
转到管理部分
点击添加用户帐户
输入用户名和密码
设置权限
点击[go]按钮

就是这样在youtube [click here ]

如果您想了解更多关于phpMyadmin go with official

但是如果有任何特殊原因要使用php，这里是sql表达

CREATE USER 'tesrytss'@'%'//user name
IDENTIFIED VIA mysql_native_password USING '***';.//set pass
GRANT SELECT, INSERT, UPDATE, DELETE, FILE ON *.* TO 'tesrytss'@'%' // previlages and username and location
REQUIRE NONE WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0; //other requerment
