linux jexus服务设置开机启动

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
