请问如何设置开机启动

[zsanjin-p]

我试了2种开机方式都不行，文件在/root/cns下

[Unit]
Description=CNS Service
After=network.target

[Service]
Type=simple
ExecStart=/root/cns/cns -daemon
Restart=always
User=root

[Install]
WantedBy=multi-user.target

#!/bin/sh

chkconfig: 345 99 10

description: cns daemon

processname: cns

pidfile: /var/run/cns.pid

configfile: /root/cns/config.cfg

Source function library.

. /etc/rc.d/init.d/functions

prog=cns
lockfile=/var/lock/subsys/$prog
pidfile=/var/run/$prog.pid
configfile=/root/cns/config.cfg
start() {
echo -n $"Starting $prog: "
daemon --pidfile=$pidfile --user=root --check $prog
$prog -f $configfile &
RETVAL=$?
[ $RETVAL -eq 0 ] && touch $lockfile
echo
return $RETVAL
}

stop() {
echo -n $"Stopping $prog: "
killproc -p $pidfile $prog
RETVAL=$?
[ $RETVAL -eq 0 ] && rm -f $lockfile $pidfile
echo
return $RETVAL
}

restart() {
stop
start
}

See how we were called.

case "$1" in
start)
start
;;
stop)
stop
;;
restart)
restart
;;
*)
echo $"Usage: $prog {start|stop|restart}"
exit 1
esac

exit $RETVAL

使用systemctl enable cns就行 程序安装的时候添加了自启程序
