NAME¶
systemd-activate - Test socket activation of daemons
SYNOPSIS¶
/usr/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
-a, --accept
-E VAR[=VALUE], --setenv=VAR[=VALUE]
-h, --help
--version
ENVIRONMENT VARIABLES¶
$LISTEN_FDS, $LISTEN_PID
$SYSTEMD_LOG_TARGET, $SYSTEMD_LOG_LEVEL, $SYSTEMD_LOG_COLOR, $SYSTEMD_LOG_LOCATION
EXAMPLES¶
Example 1. Run an echo server on port 2000
$ /usr/lib/systemd/systemd-activate -l 2000 -a cat
Example 2. Run a socket activated instance of systemd-journal-gatewayd(8)
$ /usr/lib/systemd/systemd-activate -l 19531 /usr/lib/systemd/systemd-journal-gatewayd
