Introduction There are several possible reasons why your Joomla installation might give database connection errors like 'Unable to connect to the database.' Learn how to diagnose and solve these errors to bring your website back online. Database Error When Installing Joomla If you receive a database connection error when installing Joomla and setting up your website, the most likely problem is one of the following:. Incorrect username, password, and/or database name. This is the most common cause of the error 'Database connection error (2): could not connect to mysql'. Attempting to connect to the wrong host. This is the most common cause of the error 'Database connection error (3): Could not connect to database'.
To review the Joomla installation process, consult our article. Check the Configuration File The correct username, password, and database name need to be set in the configuration.php file, which is located in your Joomla root installation folder. Edit this file with the command. Public $user = 'database username'; public $password = 'database password'; public $db = 'database name'; Make sure that the username, password, and database name match what you created in MySQL/MariaDB during the Joomla installation process.
Update the lines if necessary. Save and exit the file, then check the website to see if the problem has been resolved. Verify That the Username, Password, and Database Name are Correct If the username and password are correct, you will be able to use this information to log into MySQL/MariaDB from the command line with the command. ERROR 1045 (28000): Access denied for user 'joomlauser'@'localhost' (using password: YES) If this is the case, the simplest solution is to create a new database user by following the steps in our article. Be sure to update the configuration.php file with the new information after you have created the new user. Check the Database Host Unless you are using a different server as a remote database host, the database host should be set to localhost in the configuration.php file, which is located in your Joomla root installation folder. Edit this file with the command.
Public $host = 'localhost'; Note: Do not use your server's IP address or domain name in this field. Save and exit the file, then check the website to see if the problem has been resolved. Database Error on an Existing Joomla Website If your website was running fine before now, then MySQL/MariaDB has most likely stopped. To check this, log in to your server and use the command:.
CentOS 7: sudo systemctl status mariadb. Ubuntu 14.04: sudo service mysql status. Ubuntu 16.04: sudo systemctl status mysql If the server replies that the database has stopped, start it with the command:.
CentOS 7: sudo systemctl start mariadb. Ubuntu 14.04: sudo service mysql start. Ubuntu 16.04: sudo systemctl start mysql After the database has started, check the website to see if the problem has been resolved.
When I tried installing by uploading the package file, nothing happened. Then I tried exactly as the installation guide says for Joomla and I get this error: Please enter a package folder. Unable to find install package This is a new Joomla installation 3.8.5, I am trying to install CiviCRM 4.7.31. I have PHP 5.6. I'm hosted on a shared server so not sure how to check the PHP extensions and configuration or the MySQL version with my cPanel. I have never used CiviCRM before but I have been using Joomla for years and never got that error with any installation packages. I would love some help and am looking forward to your support.
First of all, my apologizes for my english, it is not very fluent. Now, my answer: Have you checked if this version of CiviCRM is compatible with your host PHP version? CiviCRM package is not an Autoinstaller Package as many other extensions: components or plugins.
I think the process to install is: -Upload the compressed CIVICRM package (Check than is a Joomla version) to the 'tmp' folder of your Joomnla installation. Uncompress-Expand it.Now, in your tmp folder there must contains a folder 'comcivicrm/ In administrator/extensions/install-uninstall/install from directory add the /comcivicrm/ subfolder at the end and click install. If everything goes right you will get a 'component successfully installed'. The link to Civicrm help: Good Luck!
