Configuring Apache2 as a proxy for Mattermost Server (Unofficial)
==================================================================

.. important:: This unofficial guide is maintained by the Mattermost community and this deployment configuration is not yet officially supported by Mattermost, Inc. Community testing, feedback and improvements are welcome and greatly appreciated. You can `edit this page on GitHub <https://github.com/mattermost/docs/blob/master/source/install/config-proxy-apache2.rst>`_.

The Apache2 proxy configuration is done through the ``/etc/apache2/sites-available`` directory. If you're setting up Mattermost on a subdomain you'll want to create a new configuration along the lines of ``mysubdomain.mydomain.com.conf``.

Copy the `default` configuration file found in the same directory.

**To configure Apache2 as a proxy**

1. SSH into your server
2. Create/open the above mentioned, correct file (000-default or a new subdomain configuration).
3. Edit your configuration using the guide below.

1. If you're not setting up a subdomain your ``ServerName`` will simply be set to ``mydomain.com``.
2. ``ServerAlias`` can been added too if you want to capture ``www.mydomain.com``.
3. Remember to change the values to match your server's name etc.
4. Save once finished

.. code-block:: apacheconf

<VirtualHost *:80>
# If you're not using a subdomain you may need to set a ServerAlias to:
# ServerAlias www.mydomain.com
ServerName mysubdomain.mydomain.com
ServerAdmin hostmaster@mydomain.com
ProxyPreserveHost On

# setup the proxy
<Proxy *>
Order allow,deny
Allow from all
</Proxy>

# Set web sockets
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/api/v3/users/websocket [NC,OR]
RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC,OR]
RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]
RewriteRule .* wss://127.0.0.1:8065%{REQUEST_URI} [P,QSA,L]
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
# This line simply forces HTTPS
RewriteRule (.*) https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]

<Location /api/v3/users/websocket>
Require all granted
ProxyPass ws://127.0.0.1:8065/api/v3/users/websocket
ProxyPassReverse ws://127.0.0.1:8065/api/v3/users/websocket
ProxyPassReverseCookieDomain 127.0.0.1 mysubdomain.mydomain.com
</Location>

<Location />
Require all granted
ProxyPass http://127.0.0.1:8065/
ProxyPassReverse http://127.0.0.1:8065/
ProxyPassReverseCookieDomain 127.0.0.1 mysubdomain.mydomain.com
</Location>

</VirtualHost>

4. Because you'll likely have not set up the subdomain before now on Apache2, run ``a2ensite mysubdomain.mydomain.com`` to enable the site (do not run ``a2ensite mysubdomain.mydomain.com.conf``)

5. Restart Apache2

- On Ubuntu 14.04 and RHEL 6: ``sudo service apache2 restart``
- On Ubuntu 16.04 and RHEL 7: ``sudo systemctl restart apache2``

You should be all set! Ensure that your Mattermost config file is pointing to the correct URL and then ensure that once deployed your socket connection is not dropping.

Configuring Apache2 with SSL and HTTP/2 (Unofficial)
=====================================================

.. important:: This unofficial guide is maintained by the Mattermost community and this deployment configuration is not yet officially supported by Mattermost, Inc. Community testing, feedback and improvements are welcome and greatly appreciated. You can `edit this page on GitHub <https://github.com/mattermost/docs/blob/master/source/install/config-ssl-http2-apache2.rst>`_.

Once you've configured Apache2 as a proxy for your Mattermost Server, the easiest way to enable SSL on Apache2 is via Let's Encrypt and `Certbot <https://certbot.eff.org/#ubuntuxenial-apache>`_.

Is there a link we can give for Let's Encrypt, to help an admin?

Again, not entirely sure about this as I only installed Let's Encrypt via Certbot.

Sounds good. We can tweak the guide later if someone configures it with Let's Encrypt.


Once installed, run ``$ certbot --apache`` and follow the guide. Afterwards you should find a new configuration file in ``/etc/apache2/sites-available`` which should follow the format ``mysubdomain.mydomain.com-le-ssl.conf``.

When opened, edit it to look something like the following:

.. code-block:: apacheconf

<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerName mysubdomain.mydomain.com
ServerAdmin hostmaster@mydomain.com
ProxyPreserveHost On

# setup the proxy
<Proxy *>
Order allow,deny
Allow from all
</Proxy>

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/api/v3/users/websocket [NC,OR]
RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC,OR]
RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]
RewriteRule .* ws://127.0.0.1:8065%{REQUEST_URI} [P,QSA,L]
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f

</VirtualHost>
</IfModule>

1. Restart Apache2

- On Ubuntu 14.04 and RHEL 6: ``sudo service apache2 restart``
- On Ubuntu 16.04 and RHEL 7: ``sudo systemctl restart apache2``

2. Test that the site is working, that WebSockets are working, and if you enabled HTTP redirect to HTTPS during Certbot installation that the redirect is working.
3. Lastly, test your SSL configuration with https://www.ssllabs.com/ssltest/index.html.

Using Certbot means that you shouldn't have to do anything in the configuration of Mattermost.
