I need this to test half-installed socket-activated python script, which requires PYTHONPATH and LD_LIBRARY_PATH set. I assume that other people might find it useful to. -E VAR passes through VAR from the environment, while -E VAR=value sets VAR=value. systemd-activate -E PYTHONPATH=/var/tmp/inst1/usr/lib64/python3.3/site-packages -E LD_LIBRARY_PATH=/var/tmp/inst1/usr/lib -l 2000 python3 -c 'from systemd.daemon import listen_fds; print(listen_fds())'

<title>Description</title>
|
||
|
||
<para><command>systemd-activate</command> can be used to
|
||
launch a socket activated daemon from the command-line for
|
||
testing purposes. It can also be used to launch single instances
|
||
of the daemon per connection (inetd-style).
|
||
</para>
|
||
|
||
<para>The daemon to launch and its options should be specifed
|
||
after options intended for <command>systemd-activate</command>.
|
||
</para>
|
||
|
||
<para>If the <option>-a</option> option is given, file descriptor
|
||
of the connection will be used as the standard input and output of
|
||
the launched process. Otherwise, standard input and output will be
|
||
inherited, and sockets will be passed through file descriptors 3
|
||
and higher. Sockets passed through <varname>$LISTEN_FDS</varname>
|
||
to <command>systemd-activate</command> will be passed through to
|
||
the dameon, in the original positions. Other sockets specified
|
||
with <option>--listen</option> will use consecutive descriptors.
