MySQL Web用户权限访问被拒绝

Question

I am trying to create a web user account for MySQL, but haven't able to get it working right. My user is webusr with password WebUser and the database is books .

I created the user in phpMyAdmin with SELECT, INSERT, and UPDATE only. When I run my PHP line $db = new mysqli('localhost', 'webusr', 'WebUser', 'books'); it fails with the message “Warning: mysqli::mysqli(): (HY000/1045): Access denied for user 'webusr'@'localhost' (using password: YES)”

Not sure what I am doing wrong here. The Database also has the same permissions setup. I am on a Windows PC using EasyPHP. I tried the setup with the root user without password and the code seems to work fine.

Answer 1

1: Try using PDO instead of mySQLi Why bother using PDO? click to read.
2: For now, try this:

 $db = new mysqli('localhost', 'webusr', 'WebUser', 'books'); 

instead of this:

 $db = new mysqli('localhost', webusr, WebUser, books); 

Answer 2

Most likely you're not matching the host field. In MySQL, the wildcard host % does not match socket connections, for those you need the host localhost , and if I recall correctly some versions don't even match 127.0.0.1 to % .

Since you're telling mysqli to use socket connections (by connecting to host localhost), and your user host field is not 'localhost', you're not able to connect. Edit your existing user and change the host to 'localhost' if you don't need tcp connections or add a new user with host 'localhost' if you want to continue to allow tcp connections (for instance, if you have an application on a different machine).
