I am using moodle and I change location of my web site, but I am facing this error.
My config.php is:
<?php /// Moodle Configuration File
unset($CFG);
$CFG->dbtype = 'mysql';
$CFG->dbhost = 'localhost';
$CFG->dbname = 'lightsys_test';
$CFG->dbuser = 'lightsys_test';
$CFG->dbpass = '123456a';
$CFG->dbpersist = false;
$CFG->prefix = 'mdl_';
$CFG->wwwroot = 'http://www.lightsystem.ir/aya/moodle';
$CFG->dirroot = '/home/lightsys/public_html/aya/moodle';
$CFG->dataroot = '/home/lightsys/public_html/aya/moodledata';
$CFG->admin = 'admin';
$CFG->directorypermissions = 00777; // try 02777 on a server in Safe Mode
require_once("$CFG->dirroot/lib/setup.php");
// MAKE SURE WHEN YOU EDIT THIS FILE THAT THERE ARE NO SPACES, BLANK LINES,
// RETURNS, OR ANYTHING ELSE AFTER THE TWO CHARACTERS ON THE NEXT LINE.
// /home/lightsys/public_html/aya/moodle/
?>
And my error is:
Error: Database connection failed.
It is possible that the database is overloaded or otherwise not running properly.
The site administrator should also check that the database details have been correctly specified in config.php
Thanks to everyone.
My problem is solved. I had not set the right permission to my database, for my user, and when I did it my problem was solved.
This error message could mean:
mysql server is not running on localhost (the indicated server)
any of the other parameters (db name, login, password) in config.php are wrong
Can you connect to mysql using those credentials through the mysql command line client (or phpmyadmin or similar)?
You may want to post more info about your server environment.
I had the same problem.
I edited the database port because I'm not using the default MySQL port which is 3306.
If you are using the default port, leave it as an empty string.
GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,CREATE TEMPORARY TABLES,DROP,INDEX,ALTER ON moodle.* TO username#localhost;
Use the following query to grant permissions to your user. Remember to change username with your db user that you've created.

I'm a total beginner when it comes to PHP, I have a fair grasp of the syntax but I'm not sure about the safest way to utilise it to connect to my server. I apologise that this is a sort of generic question rather than a code problem, since my code technically works.
I have a .php site doc with a basic comment submission form. The only way I can think of to connect to the server is to allow a "dummy" user with select only privelege to call a stored function to accept the comment.
If my dummy account is called siteuser then am I going round this the right way? This is the section of the PHP that I'm using to connect. I believe this code is only visible server side so nobody can ever see it and use the password or username to connect some other way? Or is there a sort of default string I can use in my php without creating the dummy user, seeing as the php and server is all hosted via the same provider?
$sqlserv = "localhost";
$sqlname = "siteuser";
$sqlpass = "mypassword";
$sqldbdb = "comments_table";
$conn = new mysqli($sqlserv, $sqlname, $sqlpass, $sqldbdb);
What i do is this to connect to my DB
db.php:
<?php
// Load configuration as an array. Use the actual location of your configuration file
$config = parse_ini_file('/somepath/config.ini');
//Mysqli Connection
$conn = new mysqli($config['host'], $config['user'], $config['pass'], $config['dbname']);
if($conn->connect_errno > 0){
die('Unable to connect to database [' . $conn->connect_error . ']');
//Set encoding
mysqli_set_charset($conn, "utf8") or die;
}
?>
and in config.ini:
[database]
user = johndoe
pass = someweirdpassword
dbname = the_name
host = localhost
both files have 700 permissions, so only user (and no one else can access it)
also the config.ini file is placed somewhere outside the public_html directory, i'm not totally sure if that helps or not but i do it that way.
I'm running into an issue while trying to link a MySQL database to a PHP file.
Im trying to setup this PHP login system from Github and currently I'm trying to setup the dbconf.php file. This is the code where I'm trying to link the database to.
<?php
//DATABASE CONNECTION VARIABLES
$host = "localhost"; // Host name
$username = "user"; // Mysql username
$password = "password"; // Mysql password
$db_name = "22445671_login"; // Database name
//DO NOT CHANGE BELOW THIS LINE UNLESS YOU CHANGE THE NAMES OF
THE MEMBERS AND LOGINATTEMPTS TABLES
$tbl_prefix = ""; //***PLANNED FEATURE, LEAVE VALUE BLANK FOR NOW***
Prefix for all database tables
$tbl_members = $tbl_prefix."members";
$tbl_attempts = $tbl_prefix."loginAttempts";
The MySQL Database is named 22445671_login
I am just looking for a way to link the MySQL database to my document
Any help is greatly appreciated, thanks.
As put into my original question before it was removed. My website is hosted at at-space which comes with a PHPmyAdmin account linked to my website, I dont know how to link the MySQL database since I don't know if the username and password are just username and password. And I dont know if the host would be 1. My Website 2. atspace or 3. PHPMyAdmin
Where is your database hosted?
You might need to replace "localhost" with the hostname of your server:
$host = "localhost"; // Host name
Make sure you have the correct username and password
Make sure the user has the necessary permissions
Not sure if PMA has this feature, but SIDU has this feature:
<?php
$url = 'http://example.com/sidu54/conn.php'
.'?conn[host]='. $host
.'&conn[user]='. $username
.'&conn[pass]='. $password
// OR .'&conn[pass]='. $encryped_pass .'&conn[penc]=1'
.'&conn[dbs]='. $db_name
.'&conn[eng]=PDO_mysql'
.'&conn[char]=utf8'
.'&cmd=Connect'
.'&url=db.php'
.'&id=1,'. $db_name;
echo 'Click here to manage database';
An application was handed to me by an old colleague to manage. However, whenever I try to run it, I keep getting this error. Please any help would do.
Sometimes Access denied Exception Error because your mysql credentials are invalid.
Secondly, from my experience i observed that this also happens because you did not set password to your database connectivity. eg
private $host = "localhost";
private $db_name = "db_dbtest"; // Database name
private $username = "db_user"; // your database username
private $password = "db_password"; // Your password
public $conn;
}
Try and set password to your database connectivity. I had such experience and after changing my Collation to utf8_general_ci on the Operations tab, this could not solve my problem. I thought of adding password to my database connection and immediately it connected.
You can tesrun this and see if it helps.
You're getting Access denied Exception Error because your mysql credentials are invalid.
This is due to the wrong sql information provided by you.Changing it to the right one can solve this error .
I was getting this same error code. I'm using phpMyAdmin and added the database with the import of a sql file. The website was using all the same code that had worked before. To fix this error go inside phpMyAdmin and click on the database then operations tab. Change the collation of my database to "ut8_general_ci". Afterwards it was able to verify the username/password access to the database.
Also you might want to make sure you added the user accounts tab the username,password and privileges to access the database.
I know this is an old question, but for me I had to set my password in Sequel Pro to the password that was listed in my .env config file. Hope this helps someone!
Well it means the SQL credentials you are using are wrong there is nothing much we can do, you need to use the correct ones or use the root account to change the user's password or rights.
You have to specify the port you are using for your MySQL. for me, I was changed the port of MySQL like 3307.
example:localhost:3307
The first thing you should check is your credentials. I thought i had root as username and password but when i looked in the file C\xampp\phpMyAdmin\config.inc.php under
$cfg['Servers'][$i]['password'] = 'WhateverPassword';
I saw that i had a different default password. You should use or change the password that is in that file when trying to connect to your database.
Make sure you have the right credentials and these are being passed to the database connection command.
Also make sure to either wrap the credentials in single quotes ' or escape them with backslash \, as there are some special characters not recognised. Hope this helps someone. Here's a reference:
String Literals
The site you got handed has the login credentials for your colleague's machine/site. Depending on the site, different files need to be changed. Example, Wordpress usually has the settings in a file called wp-config.php
Until you find this file, maybe you can change your XAMPP user login to match. This article on SO tells how to change SQL login credentials:
How do I use MySQL through XAMPP?
I am programming a game in PHP and have the following code to connect to a database
//$sqldb=mysql_connect('godaddy.hostedresource.com', 'godaddyUserName', 'godaddyPassword') OR die ('Unable to connect to database! Please try again later.');
$sqldb=mysql_connect('localhost', 'root', 'mypassword') OR die ('Unable to connect to database! Please try again later.');
The trick here is that if I am on the production server I comment out the godaddy database; when I upload the code to the server I then comment out the localhost code instead.
Unfortunately the ineveitable has happened and I uploaded the code with the wrong connection commented out; this led to 24 hours of locked out customers! :(
Is there a way to have the code to tell if it is on the localhost server, and if it isn't it then looks for the godaddy connection?
you can try this to identify if its on live or localhost
if($_SERVER["SERVER_NAME"] == "localhost"
&&
$_SERVER["SERVER_ADDR"] == "127.0.0.1"){
// in localhost
$hostname = "localhost";
$username = "localuser";
$password = "localpassword";
}else{
// not in localhost
$hostname = "livehost";
$username = "liveuser";
$password = "livepassword";
}
and fail if couldn't connect to database but save the error into a file.
if(!mysql_connect($hostname,$username,$password)){
file_put_contents("mysql_connect.error",mysql_error(),FILE_APPEND);
die("Couldn't connect to database");
}
a suggestion, try not to use mysql_* anymore, switch to PDO or mysqli ..
if ($_SERVER['SERVER_NAME'] == 'the.name.of.your.devel.server') {
$host = 'localhost';
} else {
$host = 'name.of.godaddy.server';
}
$sqldb = mysql_connect($host, ....);
i normally use a method of obtaining the URL / domain of the site? This can work in certain situations and setups. Otherwise if your operating with a fixed IP than you can also use this method
Have a look over the methods using $_SERVER
PHP $_SERVER
One way would be for you to check your external IP address and see where you are. A solution should present itself by looking at the properties inside the $_SERVER global variable.
I have a good suggestion : You coding a game , game is a big program, you don't use mysql* function directly in big program , because yourself should handling them, such as error handling.i suggest you use a DB-Handler. please google for : DB-Handler PHP
As has been mentioned by other people, you can obtain the current site your script is running on using the $_SERVER variable. However, I would like to provide an alternative solution.
You could make a folder in your website (both local and production), something like config, then store a configuration file in it, for example config.php, with the following:
<?php
// Local
$db_host = 'localhost';
$db_username = 'root';
$db_password = 'mypassword';
?>
And for production:
<?php
// Production
$db_host = 'godaddy.hostedresource.com';
$db_username = 'godaddyUserName';
$db_password = 'godaddyPassword';
?>
and disallow access to the directory with a .htaccess file in the directory, something like:
deny from all
Then, in your PHP code, do the following:
<?php
require_once($_SERVER["DOCUMENT_ROOT"] . "/config/config.php");
$sqldb=mysql_connect($db_host, $db_username, $db_password) OR die ('Unable to connect to database! Please try again later.');
?>
Now, simply leave the different configuration files where they're at and upload everything else, so your code will access different configuration files whenever it runs.
Also, the .htaccess file should prevent anyone from accessing the file via HTTP, and having the file contents in PHP tags, as well as a .php extension should prevent anyone from seeing any contents if they were able to access the file (PHP would parse the file before it is rendered, and would output nothing).
$myServer = "sql2008";
//$myUser = "zach";
//$myPass = "pass";
//$myUser = "DOMAIN/zach";
//$myPass = "pass";
//$myUser = "zach#DOMAIN.net";
//$myPass = "pass";
$myUser = "sa";
$myPass = "pass";
$myDB = "Database";
//connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
or die("Couldn't connect to SQL Server on $myServer. Error: " . mssql_get_last_message());
So what i have noticed is that i can connect with SA (server admin) but i can not connect with my user name, which is a domain user that has a lot of permissions.
the only one that is giving me an error message is when the username is zach#DOMAIN.net.
Couldn't connect to SQL Server on sql2008. Error: Login failed for user 'zach#DOMAIN.net'.
that leads me to believe that there must be some setting on the server that allows for logins, but i dont know where to look.
*UPDATE****
So after looking in SQL Server Management Studio, I realized that it accepts logins from the sysadmin server roles group. So i added my AD account to the group, but i was still not able to connect with my user name. i used they three approaches i listed above. is there a fourth option?
That being said, is there a way that i can tell it to connect to a group not sysadmin? for security reason i would prefer not to connect to sysadmin?
Go to login account properties, there's must be some tab there about status that has grant and deny option... I don't have SQL in this PC. It looks something like this:

I'm not into Active Directory that much but I have tried adding a DOMAIN/GROUP to login account in SQL server. Look at this post, it teaches how to add a login for a group in a domain. How to add Active Directory user group as login in SQL Server
The solution that I found was SQL Server did not like the fact that I was trying to use a domain account. I realized that any SQL user account that i created works fine, it is just when I try to use AD accounts it doesn't work.
I am sure that some people will want to use AD, but i don't need it in this situation.
