我有一个需要以非 root 用户身份运行的 init 脚本。我该怎么做?Ubuntu 12.04
#!/bin/sh
DEPLOY_BIN=/usr/share/deploy/bin
PID_FILE=/var/run/deploy.pid
PATH=/bin:/usr/bin:/sbin:/usr/sbin:$DEPLOY_BIN DAEMON=$DEPLOY_BIN/reporting
NAME=deploy
DESC="Deploy" if [ `id -u` -ne 0 ]; then
echo "You need root privileges to run this script"
exit 1 fi . /lib/lsb/init-functions if [ -r /etc/default/rcS ]; then
. /etc/default/rcS fi case "$1" in
start)
log_daemon_msg "Starting $DESC"
pid=`pidofproc -p $PID_FILE deploy`
if [ -n "$pid" ] ; then
log_begin_msg "Already running."
log_end_msg 0
exit 0
fi
# Start Daemon
start-stop-daemon --start --pidfile "$PID_FILE" --make-pidfile --background --exec $DAEMON
log_end_msg $?
;;
stop)
log_daemon_msg "Stopping $DESC"
if [ -f "$PID_FILE" ]; then
start-stop-daemon --stop --pidfile "$PID_FILE" \
--retry=TERM/20/KILL/5 >/dev/null
if [ $? -eq 1 ]; then
log_progress_msg "$DESC is not running but pid file exists, cleaning up"
elif [ $? -eq 3 ]; then
PID="`cat $PID_FILE`"
log_failure_msg "Failed to stop $DESC (pid $PID)"
exit 1
fi
rm -f "$PID_FILE"
else
log_progress_msg "(not running)"
fi
log_end_msg 0
;;
status)
status_of_proc -p $PID_FILE deploy && exit 0 || exit $?
;;
restart|force-reload)
if [ -f "$PID_FILE" ]; then
$0 stop
sleep 1
fi
$0 start
;;
*)
log_success_msg "Usage: $0 {start|stop|restart|force-reload|status}"
exit 1
;; esac exit 0

与流行的说法相反,su
表示“切换用户”,而不是“超级用户”。所以
su user -c command
(由 root 发出)应该可以工作。例如:
root@pern:~# su romano -c whoami
