To install Joomla, first match your host to the requirements of the Joomla package you will run, create a database and dedicated database user, upload and extract the Joomla files in the domain’s document root, then complete the browser-based installer. Shared hosting usually provides a control panel and one-click option; a VPS gives you control of PHP, the web server, firewall, TLS, and backups but makes you responsible for maintenance.
Check the Joomla version before choosing a host
Joomla requirements are version-specific. The documentation index currently identifies Joomla 6.1 as the stable documentation line, Joomla 6.2 as upcoming, and Joomla 5.4 as legacy. Download the package you actually intend to run, then use the requirements page for that major and minor version. Do not assume that a server suitable for Joomla 4 or 5 automatically meets Joomla 6 requirements.

The following figures are the Joomla 5.x technical requirements documented by the Joomla Project. They are useful when evaluating a host, but they must not be applied blindly to another major version.
| Component | Minimum | Recommended |
|---|---|---|
| PHP | 8.1.0 | 8.3 |
| MySQL | 8.0.13 | 8.1 |
| MariaDB | 10.4 | 11.1 |
| PostgreSQL | 12 | 16 |
| Apache | 2.4 | — |
| Nginx | 1.21 | 1.25 |
| IIS | 10 | — |
| PHP memory | — | At least 256 MB |
Required PHP capabilities include json, simplexml, dom, zlib, gd, and a supported database driver: mysqlnd, pdo_mysql, or pdo_pgsql. Confirm that the host can enable the modules rather than merely listing an incompatible PHP version.
#1 Best Overall
An older Joomla 4.x hosting page lists PHP 7.2.5 as a minimum, PHP 8 or newer as recommended, MySQLi 5.6 or newer or MariaDB 10.4 or newer, PostgreSQL 11 or newer, Apache 2.4 or newer, Nginx 1.18 or newer, and phpMyAdmin. It also gives example minimum settings of a 256M memory_limit, 32M upload_max_filesize, and 32M post_max_size. Those are Joomla 4 documentation values, not universal settings for current releases.
Choose between shared hosting and a VPS
Both environments can run Joomla. The important difference is who controls the server and who is accountable when something breaks.

|---|---|---|
| Server administration | The provider manages the operating system and core services. | You manage operating-system, PHP, web-server, database, firewall, and TLS updates unless a managed service is included. |
| PHP and web-server settings | Often restricted; ask whether php.ini or user.ini values can be changed. |
Normally under your control. |
| Database creation | Usually performed in a hosting panel. | Performed with the database server’s command line or administration tool. |
| Security responsibility | The provider secures the shared platform, but you still secure Joomla and extensions. | You are responsible for hardening and patching the entire machine. |
| Best fit | Sites that need a simpler setup and do not require unusual server configuration. | Sites needing predictable resources, custom services, scheduled jobs, or full configuration control. |
On shared servers, Joomla’s documentation notes that database security depends heavily on the provider. Check its patching policy, isolation between accounts, backup scope, support response, and ability to change PHP settings. Avoid a host that demands world-writable Joomla directories or requires permission mode 777.
Prepare the domain and document root
You need a hosting account and a domain for a public installation. A provider may give you an IP address or temporary URL while DNS changes propagate. You can install first on the temporary address and switch the domain later, but verify that the final domain will point to the same document root.
Rank #2
- Locate the hosting account’s document root. On many control panels it is
public_html; addon domains and subdomains commonly have separate directories. - Point the domain’s DNS records to the host’s address, or use the temporary URL supplied by the provider.
- Decide whether Joomla should load at the domain root, such as
https://example.com/, or in a subdirectory, such ashttps://example.com/blog/. - Plan HTTPS before launch. Obtain a certificate through the host or your VPS certificate-management process and ensure both the front end and administrator URL use HTTPS.
Create the Joomla database and user
Every Joomla installation requires a working database, a database user, a password, and privileges for that user. Record four values before opening the installer: database host, database name, username, and password. The database host is often localhost, but some hosts use a separate hostname.
Shared hosting with a control panel
- Open the panel’s database section, often labelled MySQL Databases or Database Wizard.
- Create a database with a site-specific name.
- Create a separate database user with a long, unique password. Do not reuse your hosting-panel password.
- Add the user to the database and grant the privileges required by Joomla. If the panel offers an “all privileges” choice for a dedicated database, use it only for that database, not for every database on the account.
- Write down the panel’s full names. Some panels prepend your account name to the database and user, so the value entered in Joomla may be different from the short name you typed.
VPS using a MySQL-compatible server
Connect to the database server as an administrative account, then create a database and a dedicated account. Replace the example names and password with your own values:
CREATE DATABASE joomla_site CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'joomla_user'@'localhost' IDENTIFIED BY 'use-a-long-unique-password';
GRANT ALL PRIVILEGES ON joomla_site.* TO 'joomla_user'@'localhost';
FLUSH PRIVILEGES;Use the actual database host in the Joomla installer. If the web server and database run on different machines, do not blindly change the account host to a wildcard; allow only the application server’s address and protect the connection according to your provider’s guidance. Keep the administrative database account out of Joomla’s configuration.
Download and place the Joomla files
Download the ZIP package for the intended Joomla version from the official Joomla project. Keep the original archive until the installation has been verified so you can check which version was deployed.
Rank #3
Upload with a hosting panel or SFTP
- Open the file manager or an SFTP client and enter the domain’s document root.
- Upload the Joomla ZIP archive. Uploading the archive is normally faster and less error-prone than transferring thousands of extracted files individually.
- Extract the archive in that directory.
- Check the resulting layout. Joomla’s
index.php, administrator directory, and other application files must be directly inside the directory served by the domain if you want the site at the domain root. - Remove an extra enclosing folder if extraction produced a path such as
public_html/Joomla_5.x/when the intended path ispublic_html/. Move the contents, not the parent directory itself, and preserve hidden files such as.htaccesswhere applicable.
Upload on a VPS with a shell
Use SFTP, SCP, or the VPS provider’s console to transfer the archive into the configured virtual-host directory. Extract it as the account that owns the website files, not as a permanent root-owned tree. A typical sequence is:
cd /var/www/example.com
unzip Joomla_package.zipThe exact path and extraction command depend on your operating system and installed utilities. After extraction, verify that the web-server virtual host points to this directory and that PHP is enabled for it.
Run the browser-based installer
With the requirements met, the database created, and the Joomla files in place, open the domain or temporary URL in a browser. Joomla starts its web installer.
- Select language and site name. Choose the installer language and enter the site name. Use a temporary name only if you are deliberately installing a staging site.
- Create the administrator account. Enter an administrator name, a unique username, a strong password, and an email address you can access. Do not use a guessable username or reuse a password from another service.
- Choose the database type. Select the engine that matches the database you created, such as MySQLi or PostgreSQL.
- Enter database connection details. Supply the database host, username, password, and database name exactly as recorded. If Joomla offers a table-prefix field, retain its generated random prefix unless you have a specific migration reason to change it.
- Choose connection encryption. Use the option appropriate for your database service. On a local database socket or same-machine connection, the provider’s documented default may be correct; on a remote database, follow the database host’s TLS requirements.
- Review pre-install checks. Resolve failed PHP-version, extension, memory, upload, or permission checks before continuing. A warning may not block installation, but understand its consequence rather than dismissing every message.
- Install. Submit the form and wait for Joomla to create its tables and configuration file. Do not refresh repeatedly during database creation.
If the installer reports a connection error, test the four connection values independently. A correct password with the wrong host, a panel-added username prefix, or a database user that was never granted access produces the same kind of failure as a mistyped password.
Rank #4
VPS configuration you must handle yourself
A VPS gives you control, but Joomla will not compensate for an incomplete server setup. Before opening the installer, configure these areas.
Web server and PHP
- Create a virtual host or server block for the domain and point its document root to the extracted Joomla directory.
- Install the PHP version required by your Joomla release and enable every required extension, including the database driver.
- Set a sufficient memory limit and upload/post limits for the Joomla package and extensions you expect to install. Reload PHP-FPM or the web server after changing configuration.
- Enable URL rewriting if you plan to use search-engine-friendly URLs. On Apache this commonly involves the rewrite module and the Joomla-provided rewrite file; on Nginx it requires the correct
try_filesrules in the server block. Use the configuration appropriate to your Joomla version and web server.
Ownership and permissions
Let the web-server process read the application and write only where Joomla genuinely needs to write. Do not make the entire tree writable by everyone. A host or script that insists on 777 permissions is a security warning. After installing an extension, review any new files and return permissions to the least-privilege state your deployment method supports.
Firewall, TLS, and updates
Allow only the ports and services you need, restrict administrative services, install a valid TLS certificate, and keep the operating system, web server, PHP, database, Joomla core, and extensions current. Schedule maintenance so security updates are not postponed indefinitely.
Shared-hosting details and common limits
Shared hosting is simpler when the provider’s defaults already satisfy Joomla. Confirm the PHP selector is set to a supported version and inspect the panel’s PHP-extension list. If you cannot change memory_limit, upload_max_filesize, post_max_size, or execution limits, ask support whether a per-account user.ini file is permitted. Do not assume that a local setting will override a provider-level restriction.
Use the panel’s backup and restore features only after confirming what they include. Some plans back up the database but not user-uploaded media, while others retain only a few recent snapshots. You still need an independently stored copy before launch.
Finish the installation and verify the site
- Sign in to the Joomla administrator area using the account created by the installer.
- Open the public front end in a separate browser window and test the home page, menu links, contact forms, media, and any sample content you elected to install.
- Confirm that the site uses HTTPS and that HTTP requests redirect as intended. Check for mixed-content warnings caused by hard-coded HTTP image or script URLs.
- Review URL-rewriting and SEO settings only after confirming that the server’s rewrite configuration is correct. If enabling them causes 404 errors, disable the setting temporarily and fix the web-server rule.
- Check file and directory ownership and permissions. The configuration file should not be publicly writable.
- Remove installation leftovers if Joomla displays an instruction to do so, and never leave an installer directory accessible.
- Open the update area and apply available Joomla core and extension updates after taking a backup.
- Record the Joomla version, PHP version, database engine/version, web-server version, document-root path, and backup location.
One-click installers: convenient, not automatic quality
Many panels offer a one-click Joomla installer. It can create the database, copy files, and open the administrator account form in a few minutes. It is reasonable for a simple shared-hosting deployment when the installer clearly identifies the Joomla version and lets you choose the database credentials.
Joomla warns that some providers’ one-click tools may install an old version. Before accepting the installation, check the version number, PHP compatibility, extension set, and update path. If the tool offers only an obsolete release, download the current package and use the manual process instead. After a one-click installation, perform the same HTTPS, permissions, update, and backup checks as a manual deployment.
Troubleshoot installation failures
| Symptom | Likely cause | Action |
|---|---|---|
| Blank page or server error before the installer appears | Unsupported PHP version, missing extension, fatal PHP error, or incorrect virtual-host configuration. | Check the host’s PHP error log, verify the required modules, confirm the document root, and select the PHP version required by your package. |
| “Could not connect to database” | Wrong host, database name, prefixed panel username, password, or missing privileges. | Log in with the same database account using an administrative client or panel test, then re-enter the exact values. |
| Installer cannot write configuration | Web-server ownership or directory permissions prevent writing. | Temporarily grant the minimum write access needed to complete installation, then restore least-privilege ownership and permissions. |
| Upload or extraction fails | File-size limit, storage quota, timeout, or an incomplete archive. | Upload the ZIP over SFTP or the panel file manager, raise limits where permitted, verify free space, and compare the archive size with the download. |
| Home page works but links return 404 | Rewrite rules are disabled or the server configuration does not match Joomla’s URL settings. | Turn off friendly URLs temporarily, enable the appropriate Apache or Nginx rewrite configuration, reload the server, and test again. |
| Administrator works but the front end is broken | Incorrect document root, damaged extraction, PHP extension issue, or an extension incompatibility. | Inspect the front-end error log, verify that Joomla core files are complete, and disable the last extension added. |
| Updates fail because files are not writable | Ownership was assigned to the wrong account or permissions were tightened too far. | Correct ownership for the deployment method, update, then return writable locations to the least privilege required. |
Back up and secure Joomla before going live
Create an off-site backup and a recovery procedure before publishing the site. A useful backup includes the database, Joomla core configuration, uploaded media, templates, and extension files. Store it outside the VPS or hosting account so a failed server, account deletion, or ransomware event cannot remove both the live site and its only backup.
Test restoration on a separate location. A backup that has never been restored is an assumption, not a recovery plan. Also remember that a backup made after compromise may contain altered files; retain clean, dated copies and investigate suspicious changes rather than restoring blindly.
Recommended Free Tools
- Use a dedicated database account with only the privileges required for the Joomla database.
- Keep the operating system, PHP, database, web server, Joomla core, templates, and extensions patched.
- Use HTTPS for the public site and administrator area.
- Protect administrator accounts with unique passwords and any available multi-factor option.
- Monitor disk space, certificate expiry, failed logins, and backup jobs.
- Document how to recreate the database, deploy the files, change DNS, and restore a backup.
Which installation method should you use?
Choose manual installation when you need a known Joomla version, a custom VPS configuration, or confidence that the package came directly from the Joomla project. Choose a one-click tool when the provider offers a current compatible release and you value speed over control. Shared hosting is appropriate when its PHP modules, database versions, permissions, and support meet the requirements; a VPS is appropriate when you need configuration control and can maintain the entire server.
The safest sequence is consistent in every environment: verify the package requirements, prepare the database and domain, place Joomla directly in the correct document root, complete the web installer, then secure, update, back up, and test the finished site before sending visitors to it.
