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
