linux下如何让控制台程序后台运行
方法1：./test &
方法2：(./test &)
方法3：nohup 和bg
方法4：screen -mS test /root/test 退出程序需要手动进入screen创建的test虚拟终端去退出
方法5：修改并保存一下代码为脚本，运行
#!/bin/bash
NAME=$(basename "$0")
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/root #程序路径
DESC=alserver#程序描述
USER=root#运行程序的用户
test -x
"$DAEMON" || exit 0
case "$1" in
start)
echo -n "Starting
$DESC: "
su "$USER" -c "$(printf "%q -q &" "$DAEMON" )"
echo "$NAME."
;;
stop)
echo -n "Stopping $DESC: "
killall --quiet "$DAEMON"
echo "$NAME."
;;
restart|force-reload)
echo -n "Restarting $DESC: "
killall
--quiet "$DAEMON"
sleep 1
su "$USER" -c "$(printf "%q -q &"
"$DAEMON" )"
;;
*)
printf "Usage: %q
{start|stop|restart|force-reload}\n" "$0" >&2
exit 1
;;
esac
exit 0
