SYSTEMD-ACTIVATE(8) systemd-activate SYSTEMD-ACTIVATE(8)
NAME
systemd-activate - Test socket activation of daemons
SYNOPSIS
/lib/systemd/systemd-activate [OPTIONS...] daemon [OPTIONS...]
DESCRIPTION
systemd-activate 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).
The daemon to launch and its options should be specifed after options intended for
systemd-activate.
If the -a 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 $LISTEN_FDS to systemd-activate will be passed through to the dameon, in
the original positions. Other sockets specified with --listen will use consecutive
descriptors.
OPTIONS
-l address, --listen=address
Listen on this address. Takes a string like "2000" or "127.0.0.1:2001".
-a, --accept
Launch a separate instance of daemon per connection and pass the connection socket as
standard input and standard output.
-E VAR[=VALUE], --setenv=VAR[=VALUE]
Add this variable to the environment of the launched process. If VAR is followed by
"=", assume that it is a variable–value pair. Otherwise, obtain the value from the
environment of systemd-activate itself.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
ENVIRONMENT VARIABLES
$LISTEN_FDS, $LISTEN_PID
See sd_listen_fds(3).
$SYSTEMD_LOG_TARGET, $SYSTEMD_LOG_LEVEL, $SYSTEMD_LOG_COLOR, $SYSTEMD_LOG_LOCATION
Same as in systemd(1).
EXAMPLE 1
$ /lib/systemd/systemd-activate -l 2000 -a cat
This runs an echo server on port 2000.
EXAMPLE 2
$ /lib/systemd/systemd-activate -l 19531 /lib/systemd/systemd-journal-gatewayd
This runs a socket activated instance of systemd-journal-gatewayd(8).
