本文为大家分享jexus服务设置开机启动的具体代码，供大家参考，具体内容如下

linux的服务开机设置一般在 /etc/init.d/里

而jexus的默认安装目录在 /usr/jexus里 启动文件为 jws 参数 有start stop restart

这里贡献一个刚写好的jexus的开启启动脚本

#!/bin/bash
### BEGIN INIT INFO
#
# Provides: jws
# Required-Start:  $local_fs $remote_fs
# Required-Stop:  $local_fs $remote_fs
# Default-Start:  2 3 4 5
# Default-Stop:   0 1 6
# Short-Description:  jws
# Description: This file should be used to construct scripts to be placed in /etc/init.d.
#
### END INIT INFO

## Fill in name of program here.
PROG=jws
PROG_PATH=/usr/jexus ## Not need, but sometimes helpful (if $PROG resides in /opt for example).
PROG_ARGS=start 
PID_PATH=/var/run/

start() {
  if [ -e $PID_PATH/$PROG.pid ]; then
    ## Program is running, exit with error.
    echo Error! $PROG is currently running! 1>&2
    exit 1
  else
    ## Change from /dev/null to something like /var/log/$PROG if you want to save output.
    $PROG_PATH/$PROG $PROG_ARGS 2>&1 >/var/log/$PROG &
  $pid=`ps ax | grep -i \'jws\' | sed \'s/^\\([0-9]\\{1,\\}\\).*/\\1/g\' | head -n 1`

    echo $PROG started
    echo $pid > $PID_PATH/$PROG.pid
  fi
}

stop() {
  echo begin stop
  if [ -e $PID_PATH/$PROG.pid ]; then
    ## Program is running, so stop it
  pid=`ps ax | grep -i \'jws\' | sed \'s/^\\([0-9]\\{1,\\}\\).*/\\1/g\' | head -n 1`
  kill $pid
    
    rm -f $PID_PATH/$PROG.pid
    echo $PROG stopped
  else
    ## Program is not running, exit with error.
    echo Error! $PROG not started! 1>&2
    exit 1
  fi
}

## Check to see if we are running as root first.
## Found at http://www.cyberciti.biz/tips/shell-root-user-check-script.html
if [ $(id -u) != 0 ]; then
  echo This script must be run as root 1>&2
  exit 1
fi

case $1 in
  start)
    start
    exit 0
  ;;
  stop)
    stop
    exit 0
  ;;
  restart)
    stop
    start
    exit 0
  ;;
  **)
    echo Usage: $0 {start|stop|restart} 1>&2
    exit 1
  ;;
esac

最后记得 sudo chmod +x /etc/init.d/jws
添加自动启动服务 sudo update-rc.d jws defaults
删除自动启动服务 sudo update-rc.d jws remove
