Installing apache tomcat with SSL configuration

• Simple configuration
• Set the context path
• Configure mod_proxy
• Set the URL for redirection
• Set the Confluence Base URL
• Complex configuration
• Adding SSL
• More information
• Alternatives

There are some common situations where you might do this:

• You have an existing Apache-based website, and want to add Confluence to the mix (for example, http://www.example.com/confluence).
• You have two or more Java applications, each running in their own application server on different ports, for example, http://localhost:8090/confluence andhttp://localhost:8080/jira. By setting up Apache with mod_proxy, you can have both available on the regular HTTP port (80) – for example, athttp://www.example.com/confluence and http://www.example.com/jira. This allows each application to be restarted, managed and debugged separately.

This page describes how to configure mod_proxy. We describe two options:

• If you want a URL like http://www.example.com/confluence/, go to the simple configuration.
• If you want a URL like http://confluence.example.com/, go to the complex configuration.

Simple configuration

Set the context path

Set your Confluence application path (the part after hostname and port) correctly. Say you want Confluence available at http://www.example.com/confluence/, and you currently have it running at http://localhost:8090/. The first step is to get Confluence available at http://localhost:8090/confluence/.

To do this in Tomcat (bundled with Confluence), edit conf/server.xml, locate the "Context" definition:

<Context path="" docBase="../confluence" debug="0" reloadable="true">

and change it to:

<Context path="/confluence" docBase="../confluence" debug="0" reloadable="true">

Then restart Confluence, and ensure you can access it at http://localhost:8090/confluence/

Configure mod_proxy

Now enable mod_proxy in Apache, and proxy requests to the application server by adding the example below to your Apache httpd.conf (note: the files may be different on your system; the JIRA docs describe the process for Ubuntu/Debian layout):

# Put this after the other LoadModule directives LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so # Put this in the main section of your configuration (or desired virtual host, if using Apache virtual hosts) ProxyRequests Off ProxyPreserveHost On <Proxy *>     Order deny,allow     Allow from all </Proxy> ProxyPass /confluence http://localhost:8090/confluence ProxyPassReverse /confluence http://localhost:8090/confluence <Location /confluence>     Order allow,deny     Allow from all </Location>

 Note to Windows Users

Set the URL for redirection

You will need to modify the server.xml file in your tomcat's conf directory and set the URL for redirection.

Locate this code segment

<Connector port="8090" maxHttpHeaderSize="8192"                maxThreads="150" minSpareThreads="25" maxSpareThreads="75"                enableLookups="false" redirectPort="8443" acceptCount="100"                connectionTimeout="20000" disableUploadTimeout="true" />

And append the following segment:

<Connector port="8090" maxHttpHeaderSize="8192"                maxThreads="150" minSpareThreads="25" maxSpareThreads="75"                enableLookups="false" redirectPort="8443" acceptCount="100"                connectionTimeout="20000" disableUploadTimeout="true"                proxyName="www.example.com" proxyPort="80" />

Replace www.example.com with the URL you wish to be redirected to.

If this isn't working for you, try adding a scheme attribute to your Connector tag: scheme="https".

Set the Confluence Base URL

The last stage is to set the Base URL to the address you're using within the proxy. For example, if you're using http://www.example.com then set your Base URL to this.

Complex configuration

Complex configuration involves using the mod_proxy_html filter to modify the proxied content en-route. This is required if the Confluence path differs between Apache and the application server. For example:

Externally accessible (Apache) URL	http://confluence.example.com/
Application server URL	http://app-server.internal.example.com:8090/confluence/

Notice that the application path in the URL is different in each. On Apache, the path is /, and on the application server the path is /confluence.

For this configuration, you need to install the mod_proxy_html module, which is not included in the standard Apache distribution. Alternative solutions are discussed below.

# Put this after the other LoadModule directives LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_http_module modules/mod_proxy_http.so LoadModule proxy_html_module modules/mod_proxy_html.so <VirtualHost *>     ServerName confluence.example.com           # Put this in the main section of your configuration (or desired virtual host, if using Apache virtual hosts)     ProxyRequests Off     ProxyPreserveHost On     <Proxy *>         Order deny,allow         Allow from all     </Proxy>           ProxyPass / http://app-server.internal.example.com:8090/confluence     ProxyPassReverse / http://app-server.internal.example.com:8090/confluence           ProxyHTMLURLMap / /confluence/           <Location />         Order allow,deny         Allow from all     </Location> </VirtualHost>

The ProxyHTMLURLMap configuration can become more complex if you have multiple applications running under this configuration. The mapping should also be placed in a Location block if the web server URL is a subdirectory and not on a virtual host. The Apache Week tutorial has more information how to do this.

Adding SSL

If you're running Apache in front of Tomcat, it's a good idea to terminate your SSL configuration at Apache, then forward the requests to Tomcat over HTTP. You can set up Apache to terminate the SSL connection and use the ProxyPass and ProxyPassReverse directives to pass the connection through to Tomcat (or the appropriate application server) which is running Confluence.

1. Create a new SSL host by creating a virtual host on 443
2. The standard http connection on apache could be used to redirect to https if you want or it could just be firewalled.
3. Within the VirtualHost definition:
   1. define the SSL options (SSLEngin and SSLCertificateFile)
   2. define the ProxyPass and ProxyPassReverse directives to pass through to Tomcat.

Most of the relevant Apache Config:

Listen 443 NameVirtualHost *:443 <VirtualHost *:443>     SSLEngine On     SSLCertificateFile /etc/apache2/ssl/apache.pem     ProxyPass / http://localhost:8090/     ProxyPassReverse / http://localhost:8090/ </VirtualHost>

Apart from the Apache configuration there is a couple of things you will need to do before you get your server working:

1. You will have to change your base URL to point o https addresses. See the documentation on configuring the server base URL.
2. We need to set up the connector to use https. In your installation directory, edit the file server.xml and add this attributes to your connector:

proxyName="proxy.example.com" proxyPort="443" scheme="https"

More information

• The mod_proxy_html site has documentation and examples on the use of this module in the complex configuration.
• Apache Week has a tutorial that deals with a complex situation involving two applications and ProxyHTMLURLMap.
• Using Apache with virtual hosts and mod_proxy shows how to configure the special case where you want JIRA and Confluence running on separate application servers on virtual host subdomains.

Alternatives

If Tomcat is your application server, you have two options:

• use mod_jk to send the requests to Tomcat
• use Tomcat's virtual hosts to make your Confluence application directory the same on the app server and the web server, removing the need for the URL mapping.

If your application server has an AJP connector, you can:

• use mod_jk to send the requests to your application server.
