perl实现检测服务器中的服务是否正常脚本分享（服务器端测试）居然可以这样

#

use strict;

use IO::Socket;

my @servers;

$servers[0]=[‘180.153.100.93’,2222];

$servers[1]=[‘180.153.100.93’,22];

$servers[2]=[‘180.153.100.93’,80];

my $i=0;

my $interval=3;

my $count=int(60/$interval);

while($i < $count){

foreach (@servers){

if(fetch_server_status(@$_)){

print $$_[0] . ‘:’ . $$_[1] .”ok\n”;

}else{

print $$_[0] . ‘:’ . $$_[1] .”bad\n”;

}

}

$i++;

sleep $interval;

}

sub fetch_server_status(){

my($ip,$port)=@_;

my $socket=IO::Socket::INET->new(

PeerAddr=> $ip,

PeerPort=> $port,

Timeout=> 1,

);

if(!$socket){

return 0;

}else{

return 1;

}

$socket->close;

}
