生成nginx配置文件,反向代理google

google的ip地址经常改变,所以要用nslookup去更新ip

#!/bin/env php
<?php
 
define("CONF_PATH", '/usr/local/nginx/conf/hosts');
 
$google_ips = __DIR__ . "/google_ips.txt"; // 保存IP地址文件
$ngx_cnf = CONF_PATH . "/51open.conf";     // NGINX配置文件
 
exec("nslookup google.com", $out, $ret); 
 
$start = false;
$ips = [];
 
foreach($out as $line) {
    // answer: 之后的是服务器对应IP
    if (false !== strpos($line, "answer:")) {
        $start = true;
    } else if (!$start) {
        continue;
    }
 
    preg_match("/Address: ((?:(?:25[0-5]|2[0-4]\d|((1\d{2})|([1-9]?\d)))\.)
    {3}(?:25[0-5]|2[0-4]\d|((1\d{2})|([1-9]?\d))))/i", $line, $matches);
    if (!empty($matches) && isset($matches[1])) {
        $ips[] = $matches[1];
    }
}
 
// 保存的IP地址
if (file_exists($google_ips)) {
    $data = file_get_contents($google_ips);
    if ($data) {
        $arr = unserialize($data);
        if (isset($arr['ips']) && date('Ymd', $arr['__logtime'])==date('Ymd')) {
            $ips = array_merge($ips, $arr['ips']);
            $ips = array_unique($ips);
        }
    }
}
 
$data = ['__logtime' => time(), 'ips' => $ips];
file_put_contents($google_ips, serialize($data));
 
$str = '';
foreach ($ips as $ip) {
    $str .= sprintf("\n    server %s:80 max_fails=3;", $ip);
}
 
if (!$str) {
    exit;
}
