Bitnami MODX

    MODX Revolution is an easy-to-use Content Management System (CMS) and Application Framework rolled into one. Despite the limitless possibilities that MODX affords you, we think you'll find it refreshingly intuitive to work with. At every step, MODX strives to deliver Creative Freedom.

    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?

    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 "/modx" you can remove the prefix from the URL executing the following command:

    $ sudo /opt/bitnami/apps/modx/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/modx.

    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/modx

    sudo /opt/bitnami/apps/modx/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/modx/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/modx/bnconfig" file.

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


    Native Installer

    Using bnconfig tool you will be able to configure the URL automatically. Some applications include an option to remove the "/modx" 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/modx/bnconfig --appurl /

    On Mac OS X, 

    installdir/apps/modx/ --appurl /

    On Windows,

    installdir/apps/modx/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/modx. If you have your application in the root URL you should include both options at the same time.

    sudo /opt/bitnami/apps/modx/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/modx/bnconfig" file.

    Tabs end

    Manual Approach

    If you want to change the default URL from http://your_domain/modx to http://your_domain, you should add a "DocumentRoot" entry in your application conf file. Edit the installdir/apps/modx/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/modx/htdocs"
    # Alias /modx/ "/installdir/apps/modx/htdocs/"
    # Alias /modx "/installdir/apps/modx/htdocs"

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

    How to create a full backup of MODX?

    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 MODX?

    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.

    How to access the Management Console in MODX?

    After the installation of the Bitnami MODX stack, you will find an example home page like this


    Example Bitnami MODX home page


    You can access the MODX manager clicking the link that you can see there, or though the URL http://localhost/modx/manager


    Login to Manager


    There, you just need to insert the username and password providing during the installation process if you are using a native installer. Check the user and password for Bitnami Cloud Hosting, AMIs and Azure Cloud Images and Virtual Machines.

    How to install a plugin on MODX?

    MODX comes with his own web-based package management. If you want to install supported addons and plugins, you can do it with the MODX Dashboard.

    How to configure the email settings of MODX?

    You can modify the mail mail settings in the System Settings options. To access to the mail options, please check the images below.

    System Settings link

    Go to Mail options once you are in System Settings


    The options that you must modify with your Email provider settings are:

    • SMTP Authentication: Yes
    • SMTP Connection Prefix: "ssl" or "tls"
    • SMTP Hosts: your email provider host.
    • SMTP Port: your email provider port.
    • SMTP User: your email user.
    • SMTP Password: your email password
    • Use SMTP: Yes

    How to test if email settings are working?

    To test your email settings, you can install the "Quick Email" plugin. Once it is installed, you only need to go to your Home page, add "!QuickEmail? &debug=`1`" to the page content and save the page.
    Once you go to your home page, the plugin will try to send an email with the one you provided during the installation (it can be modified if you click on your user at the top-right of the dashboard).

    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 MODX 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

    How do I remove the MODX cache?

    If you change your domain or IP, you will need to remove the MODX cache so that it gets this new domain. To do so, you just need to remove the following folder
