Okay, that was quick. Managed to get Apache registered to systemd as well. So now we have both of the processes Jaxer and Apache registered of services and that means that we can safely remove the entire scripts folder (yay!). For Apache, the /etc/systemd/system/apache-server.service file is written below.
[Unit] Description=Mod-Jaxer Http Server After=network.target [Service] Type=notify ExecStartPre=mkdir -p /opt/AptanaJaxer/Apache22/logs ExecStart=/opt/AptanaJaxer/Apache22/bin/apachectl start ExecStop=/opt/AptanaJaxer/Apache22/bin/apachectl stop User=root Group=root [Install] WantedBy=multi-user.target
It looks pretty simple and it is, because there’s not much to it. The original startApache.sh script sets a few environment variables and then calls apachectl. Originally I attempted to try and set the environment variables in systemd and then call the httpd executable directly, but that didn’t work out too well. So I went back and ended up using apachectl for convenience.
For the environment variables, there ended up being a file called /opt/AptanaJaxer/Apache22/bin/envvars, where the variables are set. So we added JaxerBase and Anchor to that, and then updated the file with source /opt/AptanaJaxer/Apache22/bin/envvars and that allowed us to be able to simply execute apachectl directly.

I’m not sure where the envvars gets created, or edited during the installation process. In general I would be tempted to simply edit the file using python in the Apache prepare script used to install Jaxer. I think I’ve changed enough things that I might take a chance to go back and make sure the install scripts work with a completely fresh environment, and then make sure that everything is working.
As a sidenote, slimming down the install and splitting off Apache has given us some incite into what needs to be set in order for Jaxer to be able to communicate with Apache, so we might give vanilla Apache from yum/apt-get another try now that we can debug what JaxerManager expects to be sent over port 4327 with our Nodejs proxy. Not a priority now, but a possibility. For now it seems like a good idea to take the opportunity to remove the scripts folder, add the systemd scripts into the install and then start with a fresh environment to make sure that everything is working correctly.
