Apache 2.22 Websocket Proxying on Ubuntu with mod_proxy_wstunnel
Apache, BBS, Server, Ubuntu No Comments »OK, so I am going to go geeky and deep on this one. But as part of my Color64 BBS project I needed to use a WebSocket proxy tunnel to the Color64 BBS software. It turns out Ubuntu isn’t up to the newest version of Apache. A little Googling and I came across this post.
The only problem is that it’s on someone else’s blog, which means I might forget where I found it should my server crash. 🙂 And the code for the exact steps need to be altered. So here goes with the modified steps for Apache 2.22:

# Check apache version (should be 2.2.22 as of writing, if not adjust the next step to the right version) dpkg -s apache2 # Checkout apache source svn checkout http://svn.apache.org/repos/asf/httpd/httpd/tags/2.2.22/ httpd-2.2.22 # Get patch and apply it wget http://cafarelli.fr/gentoo/apache-2.2.24-wstunnel.patch cd httpd-2.2.22 patch -p1 < ../apache-2.2.24-wstunnel.patch # Build Apache svn co http://svn.apache.org/repos/asf/apr/apr/branches/1.4.x srclib/apr svn co http://svn.apache.org/repos/asf/apr/apr-util/branches/1.3.x srclib/apr-util ./buildconf ./configure --enable-proxy=shared --enable-proxy_wstunnel=shared make # Copy the module and recompiled mod_proxy (for new symbols) to the ubuntu apache installation and update the permissions to match the other modules sudo cp modules/proxy/.libs/mod_proxy{_wstunnel,}.so /usr/lib/apache2/modules/ sudo chmod 644 /usr/lib/apache2/modules/mod_proxy{_wstunnel,}.so echo -e "# Depends: proxy\nLoadModule proxy_wstunnel_module /usr/lib/apache2/modules/mod_proxy_wstunnel.so" | sudo tee -a /etc/apache2/mods-available/proxy_wstunnel.load # Enable the module (also make any configuration changes you need) sudo a2enmod proxy_wstunnel sudo service apache2 restart |
Edit: Ubuntu may have upgraded Apache to allow for WebSocket Proxies. So I am simply posting this as a reference at this point until I update and confirm that these steps aren’t needed.
