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.
## 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

exit 0

echo "Usage: $0 {start|stop|restart}" 1>&2

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
