使用PHP拒绝访问mysql DB，但可以使用phpmyadmin和在命令行上登录

Question

Blew away that server, restarting fresh. WAY too much time wasted on this!

Let me know if I left any details out please. Have spent about a week researching this and trying things to no avail.

Creating a website (first time) for my upcoming wedding and I would like my guests to be able to post comments to the site. I am a professional software engineer but not a web dev so this was my attempt at teaching myself more about php and perl and learning to work with Linux.

Setup LAMP on Ubuntu 12.0.4 hosted on Amazon. Followed standard setup tutorial online. Apache2 with PHP5.

Created new MYSQL users (names changed for obvious reasons) user@localhost and user@% with passwords. All privileges granted to both (even on the specific DB), then flushed. Firewall port 3306 opened. bind-address in the mysql config file set to 0.0.0.0 or commented out (have tried both). Made sure not to start it with --skip-networking.

I can connect with user@localhost just fine when I run mysql -u user -hlocalhost -p as well as with phpmyadmin on the web. Correct privileges (including GRANT) are shown when I query that and I have granted each user full access to the DB I created for the site.

Now my issue is when using php or perl I cannot connect to the DB from the webpage or from running the scripts on the command line (such as sudo php script.php).

Here is the line of my php script that fails, I can post the perl if anyone would like:

mysql_connect("localhost", "user", "password")or die( mysql_error());

No matter what I do I get this error when running the script:

Access denied for user 'user'@'localhost' (using password: YES)

Same error, every dang time.

Now because I can log in with those same credentials through the command line and phpmyadmin I have to assume it is a setting I have messed somewhere on the server. I don't know what else to check aside from what I already have and what feels like hundreds of answers I have read on the subject haven't helped. If anyone could offer some advice that would be great, I am at wits end and about to trash the entire server and start fresh.

Or if no one has an answer for this, any other way I can achieve my end goal of having users be able to post comments to the site?

Answer 1

The user you're going to use with your scripting should have both the "@localhost" and "'@%'" - Have a peek at the man. http://dev.mysql.com/doc/refman/5.1/en/adding-users.html This gave me a headache once.

Answer 2

尝试这个：

    mysql_connect("127.0.0.1", "user", "password")or die( mysql_error());
