Hello everyone,
I recently tried to install and run Felix 3.0.2 on Gentoo Linux. For this
purpose, I created a start script to start and stop Felix depending on the
current runlevel (see below). Gentoo's start-stop-daemon usually is a great
choice to achieve that goal, but in this case, I am running into the following
issues:
When I start Felix using /etc/init.d/felix start, I can see the process as well as the shell's
output in the logs. However, as soon as I log out, the felix process is killed immediately
(despite the --background option to the start-stop-daemon). In addition, when I start typing
in the shell that was used to start Felix, e. g. to do a "ps aux" to list the
running processes", every second character hit is not echoed to the shell.
All this indicated a connection to the Felix shell (gogo), and the only way to solve
the problem was by removing all gogo bundles from<felix_home>/bundle. After
that, the start-stop-daemon behaved as intended and the login shell kept working as
expected.
It seems like the Gogo interactive shell is causing you difficulties.
When the Gogo shell starts up, it expects to either 1) start an
interactive session or 2) execute a command. You can avoid (1) by doing
(2) and telling it to not shutdown the framework, something like this:
java -Dgosh.args='--noshutdown -c noop=true' -jar bin/felix.jar
Then if you also install the newly released Remote Shell bundle, you can
telnet into the running framework. In fact, Gogo has a built-in telnet
command, so I think you could just directly start it like this without
the Remote Shell bundle:
java -Dgosh.args='-sc telnetd -p1234 start' -jar bin/felix.jar
Either approach will start Gogo without an interactive session and the
ability to telnet into it.

Now I guess my question would be: did I miss anything, i. e. is there a way to
start felix using java -jar<felix_home/felix.jar that starts felix in a daemon
mode?
Thanks for any hint on this!
