linux jexus 服务 设置开机启动

http://www.cnblogs.com/yahue/p/linux_jexus.html

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.

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
