Installing Joomla! for the first time is very easy. Joomla’s built-in web installer makes setting up your new site a breeze.


Hosting Requirements

Before we start, there are a couple of prerequisites that need to be met before installing Joomla 4.x successfully. These apply whether you have a dedicated server, a shared hosting plan server, or are installing a copy on a local computer for testing or development.

You’ll need to meet the following requirements to install and use Joomla


Recommended PHP.ini Settings

There are some PHP settings that need to be sufficient for Joomla to install. The settings are usually in a "php.ini" or "user.ini". Talk to your host about how to change theses settings if it is possible to do so. If working on a localhost e.g. with XAMPP, you should not be restricted by these settings and VPS or dedicated hosting should also not be as restrictive.

The values for PHP.ini below are suggested values only.

  • memory_limit - Minimum: 64M Recommended: 128M or better
  • upload_max_filesize - Minimum: 30M
  • post_max_size - Minimum: 30M
  • max_execution_time: Recommended: 30

Prepare for Install

You will need to complete two tasks before you can install Joomla on your server. First, you will need to download the Joomla package files. Next, you will need to have a database for Joomla to use.

Downloading and Uploading Joomla! Package Files

Stop hand nuvola.svg.png

Currently Joomla 4 is in development and so here we are linking you to the nightly builds. These occasionally can be unstable and should not be used on a production site. When Joomla 4.x is officially released - stable releases will be available as normal at [1]

  1. Download the current nightly release of Joomla! 4.x
  2. Move the downloaded Joomla installation package to the server. Use a FTP Client to transfer the Joomla 4.x files to your server. There are several available for use, here is a detailed list of FTP Clients. Please make sure you are using a FTP client's official release.
Hint - This can be accomplished more easily by simply moving the downloaded package to your server, then unpacking it. Alternatively you can unpack the files on your local computer, then move the Joomla installation files over to your server. Either way, the Joomla installation needs to be unpacked in the root of your site.
Your Server's "root" Folder

Normally you upload your web files to the root folder. This is typically named "public_html" but other variations include "htdocs" and this depends on how your host has the set up the server. For Joomla purposes, you can load the files directly into "public_html" or a sub-folder you have created within it.

If you unpack the files on your own computer, then copy them to your server, be sure to move only the folders and files contained INSIDE the Joomla package. If you unpack the folders and files into a folder, for example called, Joomla and then upload that folder, your site will have to be accessed at yoursitename.com/Joomla instead of yoursitename.com.

Database for Joomla! Installation

  1. If you need to create a database, please read "Create a database for use with Joomla" first or skip to step #2.
  2. You will need to note basic database information needed when the actual Joomla installation is started.
    • Location of database, localhost? Or a specific host's server such as dbserver1.yourhost.com?
    • The database name
    • The database user's name
    • The database user's password

Start Install

Main Configuration

With the above requirements met, a database created and the required Joomla files in place, you are ready to install Joomla. Start the Joomla web installer by opening your favourite browser and browsing to the site's domain name. On hosting installation you will use https://www.yoursitename.com. If your are installing Joomla locally, you will use http://localhost/<path to Joomla files> and you should see the installation screen.

Joomla will try to identify the Select Language field automatically from your browser's language. You can change this if needed.

Fill in the following information.

When everything on the first page is completed, click the Setup Login Data button to proceed:

Login Data

You should now see the login data screen.

Fill in the following information.

  • Real Name: The name of the Super User. This how Joomla will greet you when you log in!
  • Super User account username: The username for the Super User. Avoid using admin (which a good Security measure) or use My Profile in the Administration interface to change it later.
  • Admin Password: Remember that Super User has maximum control of the site (frontend & backend), so try to use a difficult password. Use My Profile in the Administration interface to change it later.
  • Super User Email Address: The Super User email address. Enter a valid email in case you forget your password. This is the email address where you'll receive a link to change the admin password.

When everything on the second page is completed, click the Setup Database Connection button to proceed:

Database Configuration

Configuration Settings

You will need to enter the information about the database you will use for Joomla! now. You may also read or review Creating a Database for Joomla!.

J40 Installation screen page 3.png

For simplification, these instructions are a reference to installing with a MySQLi database. The instructions on the installation page are self explanatory, but here they are again:

  • Database Type: MySQLi is the common database used
  • Hostname Where your database is located. Common is localhost, but some hosts use a specific database server such as dbserver1.yourhost.com
  • Username: The username used to connect to the database
  • Password: The password for the database's user
  • Database Name: The name of the database
  • Table Prefix: This is generated automatically and can be a helpful security step, but you can change it. For example, jos3_ can be used. Just don't forget to put the underscore character (_) at the end of the prefix.
  • Connection Encryption: specifies how the connection to the database should be encrypted. If you don't know - then it's best to stick to the default. However this allows enterprises who two way SSL encryption to the database to provide it.

All these choices and more can be edited on the Site Global Configuration page, under Server Options after the installation is completed. Note, you will break your installation if you change these settings after installation unless you have a complete copy of the current database being used by the Joomla installation. Common uses would be to update the username and password of the database or to complete a move of an existing installation to a new host with different parameters.

After you click the Install Joomla button, you should see the Joomla logo spinning. Once the installation completes, you should see the success page!

Finishing Up

Success and Finishing Up the Installation

Congratulations! Joomla! 4 is now installed. If you want to start using Joomla right way without installing extra languages there is one last step to complete the installation. You must delete the Installation Folder. Click on Remove Installation folder and a success message will appear. Now you can navigate to the Administrator Dashboard log in by clicking Complete & Open Admin or go right to your site by clicking Complete & Open Site.

J40 Installation screen page 4.png

You may see a section with recommended PHP settings.

  • Recommended Settings: These settings are recommended in your PHP configuration, but will not prevent Joomla! from being installed. You can refer to the above instructions on how they may be changed if there is a need to do so.

Installing Extra Languages

As part of the Joomla installation process you are given the opportunity to install additional languages before you complete the installation by deleting the Installation Folder, click on:

To do this click on the Install Additional Languages button

This will take you to an extra installation page allowing you to select the languages you require.

Install Languages

A list of language packs is displayed.


Select up to 3 languages you wish to install (more than 3 at once can cause timeout issues - you can install more later).

Remember the following:

  • Language packs included in custom distributions will not be listed at this stage as they are already installed.
  • A version of the packs proposed will match the Joomla Major version (4.0.x, 4.1.x, etc.). The minor version of the pack may not correspond, e.g. you are installing version 4.0.3 and a 4.0.2 language pack is shown.
  • Unmatched language packs in the above example may have untranslated strings.
  • The unmatched language packs will be offered as an update when the packs are updated by the registered Translation teams. The available update will be shown in the Control panel as well as in Extensions Manager  Update. This behaviour is similar to Extensions Manager  Install Languages.

Click Next and a progress bar will be display while the language pack or packs are installed.

Choose Default Language

When the installation of the languages is complete you will now be presented with a very similar Congratulations! Your Joomla site is ready. screen. The difference will be a list of the installed languages allowing you to select the default language for the Site and the Administrator interface.

  • Select the default language you wish to use.
  • When you have selected the default language, click the Set default language button to confirm.
  • A system message will be displayed confirming Joomla has set the default ADMINISTRATOR and SITE language. That message can be closed.


You must now delete the Installation Folder. Click on Remove Installation folder. You will get a confirmation message and now can navigate to the Administrator Dashboard log in by clicking Complete & Open Admin or go right to your site by clicking Complete & Open Site.
