Database Error: Unable to connect to the database: Could not connect to MySQL

pbarclay · **Joined:** Wed Nov 26, 2008 3:53 pm **Posts:** 4

I know this thread is quite old but I just like to add that I have just moved my Joomla 1.5 site from my local computer to my new hosting with a standard LAMP environment....

Once I had everything moved and configured I tried to connect to the site and got the failed to connect to MySql Database error.

After double checking the values I had entered in configuration.php where correct, I checked them again just to make sure and they were correct.

The problem was I auto generated my MySql password from the CPanel and it contained a bunch of non standard characters - changing the password to the database to something more simple fixed the connection problem.

It their a bug with the character handling for the password in Joomla 1.5?

Anyway better late than never.

I am also getting the following error "Unable to connect to the database:Could not connect to MySQL".
Not knowing any different, I have already uninstalled and reinstalled MAMP and MAMP Pro but to no avail. Please someone help!

I successfully installed Joomla and I, too kept having this issue. It was not a Joomla issue or an issue regarding passwords, etc. (I am with hostgator), and my issue is that I get the message that there is php connection error to the MySql database (there is a similar error message with Perl).

In PHPmyAdmin, I have a "no privledges" RED message next to the "create database" menu.

I had no issues with using Joomla on my Apache server on my computer, but trying to load Joomla on a web server seems to be another issue.

I have contacted hostgator, and so far, all they have been able to do is submit a trouble ticket to try to fix this. I did have them upgrade php to 5.2.2. from 4.4.4, so no idea if that is the problem.

The customer service guy on the phone had the same issue...I will post if/when this gets resolved.
...................................................
I have to say, that I am not completely convinced that I love Joomla. I still don't see how I will be able to make my web pages look and perform how I want. I like more control and flexibility...we will see. I am a COMPLETE newbie, but used to using CSS and Dreamweaver to do A LOT AND Make great looking sites that work great and are highly search able...I just need to be able to give my clients the ability to control SOME of the site....we will see....

This problem is normally a permissions issue... You can test that out by creating a new php file with the following code

Code:

<?php
$host = 'localhost';
$user = 'mysqluser';
$pass = 'mypass';
$db = 'databasename';

//Don't change below here
$conn = mysql_connect($host, $user, $pass);
mysql_select_db($db, $conn);
echo '<hr />anything above this linebreak is BAD!';

Be sure to change the top 4 vars to be your info... If you get any errors above the outputted line, get your host involved, and show them this file...

hello..
I'm new to this forum, and this particular thread because I'm having the same problem:
If I try to install Joomla! 1.5.8, I get to step 4 and I get the error "Unable to connect to the database:Could not connect to MySQL".
I have tried several fixes.
1) I have checked and re-checked PhpMyAdmin to make sure that the MsqL5 is correctly setup,
2) that the DB was setup correctly
3) that the user was setup correctly with the correct password
4) that the DB specific privleges were granted for the user; but not Global privleges
5) I have used your previous php code and named it tester.php and run it.
The output is simply a horz line and below the line the text "anything above this linebreak is BAD!"
No other errors.
6) I have deleted the installation folder from the server, because Joomla complained that it needed to be removed before it went any further. I still get the message: "Database Error: Unable to connect to the database:Could not connect to MySQL"

The server contains web pages and files for a different web page.
I am trying to install Joomla from a subfolder...is that a problem?

I am using the Joomla Magic 1.5 tutorial package to learn this.
So far I think I've done everything correctly. It seems simple enough.

What is my next step? Should I uninstall/delete joomla from the server and delete the MSQL5 and
DB from the server and start all over again?
I have no idea what to do next.

Help!

After much research and reading and fretting, the solution to my problem to the error "Unable to connect to the database:Could not connect to MySQL" was a very simple one - somehow the admin password got changed. Not surprisingly, I don't think I did anything to change the password - at least not purposely. Regardless entering the new PW fixed the problem and I am able to set up Joomla.

Would you be willing to share the steps of your fix and what you mean as 'admin password'?

I'm afraid I've tried so many things that I've possibly changed something that I originally setup,
and don't remember going back to that step...know what I mean?

Thanks

I have the same problem here...
But, after I create a new mysql user (with new password) and synchronize with configuration.php file, the problem is gone.
So, my conclusion is I haven't put the right username and password at configuration.php file. Please check your username and password again.
If you are not sure enough, please create the new one....

Thanks,

binachank,
Thank you for the advice. I was able to solve my proble the same way you did.
Apparently, I had a wrong password, that conflicted with my connection to the DB.
once I made sure they were the same pw, it worked.
This one is solved for me.

Had the same problem with a clean installation of joomla 1.5.9. This is what happened to me: when I created the database I wrote down the database name and username. Filled out these names in Joomla and clicked on next in the Joomla setup screen. Then got the above problem/message of Joomla not being able to connect. Well I found out that the database (mysql) adds/changes the names of the database and user after you've created them. So I copied these by the database altered names and pasted them in Joomla setup. Problem solved. Hope it will help someone here.
Cheers Nico

Unless you install locally, most web hosting will automatically add the unix user account as a prefix to database name and username.

Yeah, I've just got the same problem at a most critical time. A meeting to show client website in 2 hours time and I get this.
"Database Error: Unable to connect to the database: Could not connect to MySQL"

Can't connect to the Cpanel, MYSQL, MY Admin or Website

I contacted the host who said they've got the problem and will have it fixed within 15 minutes (sounds like wishfull thinking to me). Anyway, I'm not going to touch a thing for 10 minutes then see what happens. It just feels like I've got not control over this side of things.

Damn it.
I'm totally hamstrung and at the mercy of the HOST. Not happy Janet! :eek:

Hi Everyone!

I am very new to Joomla and I also encountered this "Unable to connect to the database:Could not connect to MySQL" problem. I hope someone out there will give me a step to step idea on how to deal with it.
By the way in the Pre Installation check, my Display Errors is still ON. And I tried to go to the php.ini but it said there that it is OFF. So I was just thinking if this had to do with the problem about the Database.

Oh please help me.
Thanks in advance.

Actually looking back at an old post I read where the characters in your database name could be the problem. Some hosts have restrictions on how long a name can be. I simply made the database name shorter as well as the username shorter and that fixed the problem. Instead of using 10 or more characters I just used like a number right after the hostname. For example hostname_2 as username name and hostname_2 as the database name.

I had the same error "Unable to connect to the database:Could not connect to MySQL" after installing a joomla template on another domain in the same hosting company (Hostgator). I created another MySql database and I think HERE COMES THE MISTAKE I GAVE THE SAME USERNAME to this database. After that I could not access any of my two sites.
So here is what I did:

1- Delete the new created database and site (the main one was the important one so I din't want to mess things up
2- I deleted the username (in the case it had been corrupted) created a new one with all the privileges on- by the way-(I named it the same as before so I had not to touch the PhpmyAdmin)
3- Voila!!! everything was back to normal

So big lesson is: DO NOT GIVE THE SAME USERNAME TO DIFFERENT DATABASES....you risk the dreaded "Unable to connect to the database: Could not connect to MySQL" message

Hope my experience is of any help

best

after all password on all sites have been set same. it is fine.

hope this helps

You need to contact your host. I'm certain it's a problem at their end.
Good luck.

The issue for me seems that you can't have the £ symbol (that's the symbol over the number 3 on my keyboard) in your password. Now, that's what I call a real gotta! Must be something to do with the way the Joomla install program is handling/mishandling password parsing.

I have the same problem when manually installing Joomla on my Yahoo hosted account. When I get to the "Database Configuration" page I entered the following:
Database Type: mysql
Host Name: localhost
Username: STM-DB (the username I use to log in to my "phpMyAdmin" account)
Password: xxxxxxx (the password I use to log in to my "phpMyAdmin" account)
Database Name: stmj (the database I created in "phpMyAdmin" account)

When I click "Next" I get an error message "Unable to connect to the database." What am I doing wrong? Thanks.

I'm trying to move my joomla1.5.9 site from a local server to a live web server and am getting this same message: Database Error: Unable to connect to the database:Could not connect to MySQL

I think I've tried just about everything in this thread to fix it, but no luck.

PLEASE someone help. I'll provide my configuration.php settings if someone will look at them. It'd be greatly appreciated as I've put a lot of time into this site and this is getting very frustrating.

Thanks.

Have you established the databases at/with your host service?

I've created a new database (and user) and imported the local .sql file on my host account.

keefrichards · **Posted:** Wed Jun 03, 2009 7:39 am

Can you get anything at all?
for instance, can you navigate to :

http://www.yoursite.com/administrator
or
http://www.yoursite.com/index
or
http://www.yoursite.com/index.htm

Is there anything at all on the server like htaccess files?

What is the site's address?

I get the db error with /administrator
I get a 404 error with /index
With /index.html, I get the test page that my host put up when we tried to work through the problem yesterday. (they weren't much help)

Yes, I have an htaccess file on my server.

What the hell have I done? I didn't fill out the confiugration.php correctly, right?

Thanks for the help!

keefrichards · **Posted:** Wed Jun 03, 2009 6:57 pm

First thing to do would be to try and install a joomla!, any joomla, (but not the one you've just built) onto the remote server. Just to see that the server is handling Joomla! properly. Do a fresh joomla install.

If that doesn't work, then it's a problem with your host.

If it does work, overwrite the insalled files with your new rebuilt files.

Good luck,

I was locked out of my admin panel for my website, so I found a solution:

Quote:

Directions
1. Use a MySQL utility such as phpMyAdmin or MySQL Query Browser .
2. Open the correct database and select the table, jos_users . (Change default table prefix, 'jos_' to your table prefix if it is different.)
3. Select the record (or table row) for your administrator account. (The default Super Administrator is user number 62.)
4. Copy and paste a known MD5 hash into the password field. You can use one of the below examples. Warning: You must paste the password's hash value, not the password itself. You can use any of the following hashs, or create your own using one of the MD5 tools listed below.
password = "MD5 hash of password"
------------------------------------------------------
admin = 21232f297a57a5a743894a0e4a801fc3
secret = 5ebe2294ecd0e0f08eab7690d2a6ee69
OU812 = 7441de5382cf4fecbaa9a8c538e76783
5. Save the user record.
6. Point a browser to your site and log in using the Super Administrator account you just modified.
7. IMPORTANT: Once logged in, use the Joomla interface to change the password to one that only you know. This step is vital as it will 'salt' your new password, thus adding an additional level of security on top of the MD5 hash.
Note: This technique can be used to modify any other accounts password. You can also use it to change Usernames.

I followed the directions and was able to change my super admin password information, but when point my browser to my website to access my admin panel, I get an error:
