Run go app by service

In CentOS 6.8 I have a golang app , that run in command go run main.go and I need to create a system service to run it in boot like service httpd.<br>
I know that I have to create file like /etc/rc.d/init.d/httpd But I don't know how to do it to run that command.

First, you will need to build your Go binary and put it in your path.

go install main.go

If your "main" file is called main, go install will place a binary called "main" in your path, so I suggest you rename your file to whatever you call your project/server.

mv main.go coolserver.go
go install coolserver.go

You can run coolserver to make sure everything is fine. It will if you have your $GOPATH setup properly.

Here it is an example of a init.d service called service.sh

#!/bin/sh
### BEGIN INIT INFO
# Provides:          <NAME>
# Required-Start:    $local_fs $network $named $time $syslog
# Required-Stop:     $local_fs $network $named $time $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Description:       <DESCRIPTION>
### END INIT INFO

SCRIPT=<COMMAND>
FLAGS="--auth=user:password"
RUNAS=<USERNAME>

PIDFILE=/var/run/<NAME>.pid
LOGFILE=/var/log/<NAME>.log

start() {
  if [ -f /var/run/$PIDNAME ] && kill -0 $(cat /var/run/$PIDNAME); then
    echo 'Service already running' >&2
    return 1
  fi
  echo 'Starting service…' >&2
  local CMD="$SCRIPT  $FLAGS &> \"$LOGFILE\" & echo $!"
  su -c "$CMD" $RUNAS > "$PIDFILE"
  echo 'Service started' >&2
}

stop() {
  if [ ! -f "$PIDFILE" ] || ! kill -0 $(cat "$PIDFILE"); then
    echo 'Service not running' >&2
    return 1
  fi
  echo 'Stopping service…' >&2
  kill -15 $(cat "$PIDFILE") && rm -f "$PIDFILE"
  echo 'Service stopped' >&2
}

uninstall() {
  echo -n "Are you really sure you want to uninstall this service? That cannot be undone. [yes|No] "
  local SURE
  read SURE
  if [ "$SURE" = "yes" ]; then
    stop
    rm -f "$PIDFILE"
    echo "Notice: log file is not be removed: '$LOGFILE'" >&2
    update-rc.d -f <NAME> remove
    rm -fv "$0"
  fi
}

case "$1" in
  start)
    start
    ;;
  stop)
    stop
    ;;
  uninstall)
    uninstall
    ;;
  restart)
    stop
    start
    ;;
  *)
    echo "Usage: $0 {start|stop|restart|uninstall}"
esac

Copy to /etc/init.d:

cp "service.sh" "/etc/init.d/coolserver"
chmod +x /etc/init.d/coolserver

Remember to replace

<NAME> = coolserver
<DESCRIPTION> = Describe your service here (be concise)
<COMMAND> = /path/to/coolserver
<USER> = Login of the system user the script should be run as 

Start and test your service and install the service to be run at boot-time:

service coolserver start
service coolserver stop
update-rc.d coolserver defaults

I assume you tried to use apache web server. Actually, Go web server is enough itself. Main purpose is to run Go web server in system service.So, you can use tmux https://tmux.github.io/ or nohup to run as system service. You can also use apache or nginx web server as proxy.
