我在 Amazon WebServices 中触发了一个 EC2 实例。我还在 /etc/init.d 文件夹中创建了一个名为 shutdownSocketServer 的服务,我希望它在关机和重启时被调用。

我已将它添加到chkconfig -add,并且我检查了它是用

sudo chkconfig --list | grep shutdownSocketServer
shutdownSocketServer    0:on    1:off   2:off   3:off   4:off   5:off   6:on

脚本是:

#!/bin/bash                                                                      
# chkconfig: 06 001 001
# description: Foo server

. /etc/init.d/functions
sudo touch /var/lock/subsys/shutdownSocketServer

start(){
    EC2_INSTANCE_ID="`wget -q -O - http://169.254.169.254/latest/meta-data/instance-id || die \"wget instance-id has failed: $?\"`"
    echo "$EC2_INSTANCE_ID"

    curl "http://mywebservice.com/Server/functions/SocketUpdater.php?   estado=shutdown&instance_id=$EC2_INSTANCE_ID"
}

stop(){
    echo "stopping"
}

### main logic ###
case "$1" in
    start)
        start
    ;;
    stop)
        stop
    ;;
    status)
        status
    ;;
    restart|reload|condrestart)
        stop
        start
    ;;
    *)
        echo "Usage: $0 {start|stop|restart|reload|status}"
        exit 1
esac 
exit 0

所以我的问题是我认为当 EC2 关闭时网络无法访问。怎么能避免呢?我怎样才能检查它?
