Some users need to start the service when the system is powered on. This article will explain how to start the Ngrok client automatically when the system is powered on under Linux.

This article supports Ubuntu, raspberry pie, Centos7, Debian series of systems.

If the Centos system does not have start stop daemon installed, see Centos install start stop daemon

Operation steps

• 1. Download client
• 2. Script
• 3. Test script
• 4. Set startup

Ngrok client download

1. Download client

It goes without saying that everyone knows how to operate this step. After the download is completed, move the client execution file to the / use/local/bin directory and give the executable permission.

sudo mv sunny /usr/local/bin/sunny
sudo chmod +x /usr/local/bin/sunny

2. Writing startup scripts

sudo vim /etc/init.d/sunny

/etc/init.d/sunny startup script code

#!/bin/sh -e
### BEGIN INIT INFO
# Provides:          ngrok.cc
# Required-Start:    $network $remote_fs $local_fs
# Required-Stop:     $network $remote_fs $local_fs
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: autostartup of ngrok for Linux
### END INIT INFO

NAME=sunny
DAEMON=/usr/local/bin/$NAME
PIDFILE=/var/run/$NAME.pid

[ -x "$DAEMON" ] || exit 0

case "$1" in
  start)
      if [ -f $PIDFILE ]; then
        echo "$NAME already running..."
        echo -e "\033[1;35mStart Fail\033[0m"
      else
        echo "Starting $NAME..."
		start-stop-daemon -S -p $PIDFILE -m -b -o -q -x $DAEMON -- clientid Tunnel id || return 2
        echo -e "\033[1;32mStart Success\033[0m"
    fi
    ;;
  stop)
        echo "Stoping $NAME..."
        start-stop-daemon -K -p $PIDFILE -s TERM -o -q || return 2
        rm -rf $PIDFILE
        echo -e "\033[1;32mStop Success\033[0m"
    ;;
  restart)
    $0 stop && sleep 2 && $0 start
    ;;
  *)
    echo "Usage: $0 {start|stop|restart}"
    exit 1
    ;;
esac
exit 0

3. Test executable code

sudo chmod 755 /etc/init.d/sunny
sudo /etc/init.d/sunny start
sudo /etc/init.d/sunny start    #start-up
sudo /etc/init.d/sunny stop     #Stop it
sudo /etc/init.d/sunny restart  #restart

4. Set startup

cd /etc/init.d
sudo update-rc.d sunny defaults 90    #chkconfig mysqld on 
sudo update-rc.d -f sunny remove  #Cancel startup

sudo chkconfig --add sunny 	#Add system service
sudo chkconfig --del sunny	#Delete system service
sudo chkconfig --list		#View system services
sudo chkconfig sunny on 	#Set startup
sudo chkconfig sunny off 	#Set to cancel startup
service sunny start 		#start-up
service sunny stop 			#Close
service sunny restart 		#restart

Centos install start stop daemon

wget http://developer.axis.com/download/distribution/apps-sys-utils-start-stop-daemon-IR1_9_18-2.tar.gz
tar -xzvf apps-sys-utils-start-stop-daemon-IR1_9_18-2.tar.gz
# Then go to the path after decompression and cd to the directory where start-stop-daemon.c is located 
cc start-stop-daemon.c -o start-stop-daemon
cp start-stop-daemon /usr/bin/start-stop-daemon
