    Joomla! is an open source Content Management System with a growing and active community. Joomla! creates multiple format sites from simple websites to complex corporate applications and allows users to manage each aspect of their website through a simple, browser-based interface. Once Joomla! is up and running, users with basic word processing skills can add or edit content, update images, and to manage the critical data. Joomla! also allows developers to create and include add-ons to further customize their site.

    Please, take a look to the Quick Start Guide to know the basic use of this Stack.

    How to start/stop the servers?

    Graphical tool

    The Stacks include a graphical tool to manage the servers easily. You can find the "manager-windows.exe", "manager-osx" or "manager-linux" tool in your installation directory. Using this tool, you can Start, Stop or Restart the servers and check the log files. You can click on the icon to start it.














    On Windows: You can also start the Manager tool from shortcuts: Start -> Program Files -> BitNami Stack -> Manager tool

    Command line tool

    If you prefer, you can use the "" utility from the command line. This script is in the installation directory.


    On Virtual Machines and Cloud images:

    $ sudo /opt/bitnami/ start

    A native installer on Linux:

    $ cd ~/application-version
    $ ./ start



    On OS X: You can start the Manager tool from the installation directory or you can use the "" utility from a Terminal.

    host:~ user$ cd /Applications/application-version
    host:~ user$ ./ start

    How to change the default URL to root?

    This approach describes how to configure your application to run in the root URL directly. Also, you will be able to modify the URL to a NEW_DOMAIN using the bnconfig tool. The details are described below.

    Automatic Approach

    This approach is based on the bnconfig tool. For more information about the Bitnami Configuration tool, please take a look in this wiki entry

    Bitnami Cloud Hosting

    The best way to change your URL in BCH is to go to your application tab and modify it there. In the Bitnami Cloud Hosting console, select Servers, choose your server, Manage and go to the Applications tab. Press there the pencil next to the application which URL you want to modify and choose .

    Cloud Images and Virtual Machines

    Moving the application to /

     If your application is running in "/joomla" you can remove the prefix from the URL executing the following command:

    $ sudo /opt/bitnami/apps/joomla/bnconfig --appurl /

    (use --help to check if that option is available for your application)

    Now you will be able to access to the application at http://YOUR_DOMAIN instead of http://YOUR_DOMAIN/joomla.

    Updating the IP or hostname

    Some applications require to update the IP/domain if the machine IP/domain changes. The bnconfig tool also has an option which updates the IP automatically during boot, called machine_hostname (use --help to check if that option is available for your application). Note that this tool changes the URL to http://NEW_DOMAIN/joomla

    sudo /opt/bitnami/apps/joomla/bnconfig --machine_hostname NEW_DOMAIN

    If you already moved your application to the root URL you should include both options at the same time.

    sudo /opt/bitnami/apps/joomla/bnconfig --appurl / --machine_hostname NEW_DOMAIN


    If you have configured your machine to use an static domain name or IP, you should rename or remove the "/opt/bitnami/apps/joomla/bnconfig" file.

    sudo mv /opt/bitnami/apps/joomla/bnconfig /opt/bitnami/apps/joomla/bnconfig.disabled


    Native Installer

    Using bnconfig tool you will be able to configure the URL automatically. Some applications include an option to remove the "/joomla" prefix from the URL (use --help to check if that option is available for your application). If you want to modify that you can run the following command (substitute installdir with your actual installation directory):

    On Linux,

    installdir/apps/joomla/bnconfig --appurl /

    On Mac OS X, 

    installdir/apps/joomla/ --appurl /

    On Windows,

    installdir/apps/joomla/bnconfig.exe --appurl /

    The bnconfig tool also has an option which updates the IP automatically during boot, called machine_hostname (use --help to check if that option is available for your application). Note that this tool changes the URL to http://NEW_DOMAIN/joomla. If you have your application in the root URL you should include both options at the same time.

    sudo /opt/bitnami/apps/joomla/bnconfig --machine_hostname NEW_DOMAIN

    If you have configured your application to use an static domain name or IP, you should rename or remove the "installdir/apps/joomla/bnconfig" file.

    Tabs end

    Manual Approach

    If you want to change the default URL from http://your_domain/joomla to http://your_domain, you should add a "DocumentRoot" entry in your application conf file. Edit the installdir/apps/joomla/conf/httpd-prefix.conf file to add this line and commenting the "Alias" entries. Modify the

    httpd_prefix.conf file content (substitute installdir with your actual installation directory, which is /opt/bitnami in Cloud Images and Virtual Machines):

    DocumentRoot "/installdir/apps/joomla/htdocs"
    # Alias /joomla/ "/installdir/apps/joomla/htdocs/"
    # Alias /joomla "/installdir/apps/joomla/htdocs"

    Some applications also require changes in their configuration files or in the database.

    In this case it is also necessary to modify the following lines in "installdir/apps/joomla/conf/htaccess.conf" file:

    # RewriteBase /joomla
    RewriteBase /

    Finally restart the Apache server:

    $ /installdir/ restart apache

    How to create a full backup of Joomla!?

    Because BitNami stacks are self-contained, the simplest option for performing your backups is to copy or compress the BitNami Stack installation directory. To do so in a safe manner, you will need to stop all servers, so this method may not be appropriate if you have people accessing the application continously.

    linux_platform.pngOn Virtual Machines and Cloud Images:

    sudo /opt/bitnami/ stop


    On OS X:

    $ cd installdir
    $ ./ stop
    $ cp -r installdir application-backup

    Or you can create a tarball:

    $ tar -czvf application-backup.tar.gz installdir

    Or a zip file:

    $ zip -r installdir/*

    To restore this backup you only need to uncompress the backup in the same location. It is important to use the same path that was used when the stack was originally installed.

    For example if you have a backup in a Red Hat machine, you can copy it to an Ubuntu Linux machine (a different distro!) in the same location. Then start the servers and that’s all.

    On Virtual Machines and Cloud Images:

    $ sudo /opt/bitnami/ start

    On OS X:

    $ cd installdir
    $ ./ start

    You just need to be carefull to keep the same permissions for the files and folders. If you installed as root make sure that in the new machine you copy the files also as root. And this case, if you are also moving MySQL or PostgreSQL, you will need to create those users in the new machine (if they don't exist yet).

    win_platform.png On Windows you should follow the same process. Stop the servers using the shortcuts and copy the whole installation directory. To restore the system, copy the directory to a different Windows machine in the same location and follow these steps from a command prompt:

    $ cd installdir
    $ serviceinstall.bat INSTALL

    You can access your BitNami Application at the usual URL.

    If you want to create only a database backup, check the following link for MySQL /Components/MySQL#How_to_create_a_database_backup or for PostgreSQL /Components/PostgreSQL#How_to_create_a_database_backup.3f

    How to upgrade Joomla!?

    It is strongly recommended that you create a backup before starting the update process. If you have important data, it is advisable that you create and try to restore a backup to ensure that everything works properly.

    There are two different ways to upgrade your application.

    1. If you want to upgrade the application and all Stack components PHP, Ruby, MySQL, Apache… You can follow the steps described at How to upgrade the full Stack migrating the data?
    2. In case you only want to upgrade the application code without modifying any other Stack components,  you should follow the guide which is in the application page itself.

    Upgrading Joomla! from the application

    If you want to upgrade only Joomla! application, it is possible to upgrade it from the Admin panel. 


    IMPORTANT. Joomla! update process does not work properly from the "Joomla! Update" section. You can find more info at  If you try to update Joomla! from the "Joomla! Update" instead of the extension manager, you will find permission errors trying to copy files.

    It is suggested that rather than use the updater you install the new Joomla version using the standard extension manager install.

    • Click on the "Joomla! new version, Update now!" link:


    • Copy the URL of the new Patch Package


    • Go to "Extensions" -> "Extension Manager" and click on the "Install from URL" tab. Copy the previous link there and click on the "Install" button.


    • If you find any Database error it is possible that you should run the "Fix database". Go to Extension Manager -> Database and click in the "Fix" button.

    How to install a plugin on Joomla!?

    You can install any modules from the "Plugins Manager" tool in the Administrator Panel. You can upload the module directly or can specify the link to the download. Recent versions of Joomla! Virtual Machines or AMIs already configure FTP automatically, it is not necessary to modify it.

    If you have installed the Stack in your machine, it is necessary to install a FTP server in your machine. These are the settings that you should use:

    FTP Host:
    FTP Port: 21
    FTP Username: your machine user
    FTP Password: (the password of your user)

    How to configure the email settings of Joomla!?

    If you are using the Naitve Installer or Bitnami Cloud Hosting, you can configure the email settings during the deploy. In other case, you can configure the email settings at "Global Configuration" -> "Server". You can use the "SMTP" at the mailer and configure it with your email server provider. GMail, Yahoo and others allow to send emails with your account.

    For instance, using GMail:

    Mailer: SMTP
    From email:
    From name: My Name
    SMTP Authentication: Yes
    SMTP Security: TLS
    SMTP Port: 587
    SMTP Username:
    SMTP Password: your account password
    SMTP Host:

    How to translate Joomla! to my language?

    BitNami Joomla! has already installed English, Spanish and more translations currently. If you want to change the Joomla language you can follow these steps:

    1. Download your language translation from
    2. Go to Extensions ->Extension Manager in the administration panel and upload the package.
    3. Go to Extensions -> Language Manager and enable your language for the Site and for the Administration panel.

    How to enable SSL?

    You can see how to configure Apache to enable SSL connections at How to enable SSL to access through https?

    How to debug Joomla! errors?

    Once Apache starts, it will create two log files, the access_log and the error_log /installdir/apache2/logs directory or in /var/log/httpd if you are using Amazon Linux or Red Hat Enterprise cloud images.

    In Virtual Machines, Cloud Images and Ubuntu based Bitnami Cloud Hosting images installdir is /opt/bitnami.

    The access_log file is used to track client requests. When a client requests a document from the server, Apache records several parameters associated with the request in this file, such as: the IP address of the client, the document requested, the HTTP status code, and the current time.

    The error_log file is used to record important events. This file includes error messages, startup messages, and any other significant events in the life cycle of the server. This is the first place to look when you run into a problem when using Apache.

    If no error is found, you will see a message similar to:

    Syntax OK
    /installdir/ : httpd started

    The main MySQL log file is created at /installdir/mysql/data/mysqld.log file.

    How to increase the allowed size of the uploaded files?

    You can modify the following option in the php.ini file to increase the allowed size for uploads:

    ; Maximum size of POST data that PHP will accept.
    post_max_size = 16M
    ; Maximum allowed size for uploaded files.
    upload_max_filesize = 16M
