php - Global Traffic Director - 需要 Ubuntu、LAMP 和 Nginx 帮助的 DO droplet

Question

我一直在尝试遵循 Digital Ocean 以下示例:
https://www.digitalocean.com/community/tutorials/how-to-use-nginx-as-a-global-traffic-director-on-debian-or-ubuntu

已经用 Ubuntu 设置了一个 droplet，并且已经有 LAMP 堆栈。

尽管在 LAMP 堆栈顶部配置了 Nginx 以尝试使用 GeoIP 数据库，但当我运行包含以下代码的 test.php 文件时:

 <?php
     if (getenv(HTTP_X_FORWARDED_FOR)) {
        $sname = getenv(SERVER_NAME);
        $sipaddress = getenv(SERVER_ADDR);
        $pipaddress = getenv(HTTP_X_FORWARDED_FOR);
        $ipaddress = getenv(REMOTE_ADDR);
        echo "$sname server has address : $sipaddress";
        echo "<br />\n";
        echo "Your Proxy IP address is : ".$pipaddress. " (via $ipaddress) " ;
    } else {
        $servername = getenv(SERVER_NAME);
        $serveripaddress = getenv(SERVER_ADDR);
        $ipaddress = getenv(REMOTE_ADDR);
        echo "$servername server has address : $serveripaddress";
        echo "<br />\n";
        echo "Your IP address is : $ipaddress";
    }
    $country = getenv(GEOIP_COUNTRY_NAME);
    $country_code = getenv(GEOIP_COUNTRY_CODE);
    echo "<br/>Your country : $country ( $country_code ) ";
?>

我得到以下实时响应:

www.mydomain.com server has address : 12.34.56.78
Your IP address is : 87.65.43.21
Your country : ( )

如您所见，IP 地址是正确的，这表明 PHP 工作正常，但不幸的是，尽管本地存在，但所有 GEOIP 变量都没有工作。

所以我的问题是:

我哪里搞砸了？

为什么 GeoIP 数据不通过 Nginx？

以下是我为配置服务器而采取的一些额外步骤。

我将默认配置文件从/etc/nginx/sites-available 重命名为我的域名，并确保在/etc/nginx/sites-enabled 中创建一个指向它的新链接。

然后我的配置文件现在看起来像这样:

map $geoip_city_continent_code $closest_server {
  default eu.mydomain.com;
  US      US.mydomain.com;
  AS      as.mydomain.com;
}

server {

server_name mydomain.com
            www.mydomain.com
            eu.mydomain.com
            us.mydomain.com
            as.mydomain.com;

if ($closest_server != $host) {
  rewrite ^ $scheme://$closest_server$request_uri break;
}

listen 80 eu.mydomain.com;
listen [::]:80 eu.mydomain.com ipv6only=on;

root /var/www/html;
index index.html index.htm;

# Make site accessible from http://localhost/
server_name localhost;

最终目标是拥有 3 台服务器(美国、欧洲、亚洲)，以欧盟为中心，并使用以下任一服务器重新路由到最近的服务器:us.mydomain.com 或 eu.mydomain.com 或 as.mydomain.com

我希望这足够清楚任何指针都会很棒!

感谢您的时间。

Answer 1

我最终在构建液滴时使用了 LEMP 堆栈，并从 Digital Ocean 文档中发现了一些缺失的信息，如下所示:

在/etc/nginx/nginx.conf 文件中添加这两行:

geoipcountry/usr/share/GeoIP/GeoIP.dat；

geoipcity/usr/share/GeoIP/GeoLiteCity.dat；

然后在/etc/nginx/fastcgiparams 最后添加:

fastcgiparam REDIRECTSTATUS 200;
fastcgiparam GEOIPADDR $remoteaddr;
fastcgiparam GEOIPCOUNTRYCODE $geoipcountrycode;
fastcgiparam GEOIPCOUNTRYNAME $geoipcountryname;
fastcgiparam GEOIPREGION $geoipregion;
fastcgiparam GEOIPREGIONNAME $geoipregionname;
fastcgiparam GEOIPCITY $geoipcity;
fastcgi_param GEOIP_CITY_CONTINENT_CODE $geoip_city_continent_code; #EDIT
fastcgiparam GEOIPAREACODE $geoipareacode;
fastcgiparam GEOIPLATITUDE $geoiplatitude;
fastcgiparam GEOIPLONGITUDE $geoiplongitude;
fastcgiparam GEOIPPOSTALCODE $geoippostal_code;

然后在/etc/nginx/sites-available/default 中，默认文件中每个服务器之间的区别也在 map $geoipcountrycode $closest_server { 级别处理如下:

编辑!!

美国服务器:

map $geoip_city_continent_code $closest_server {
  default www.yourdomain.com;

  AF      eu.yourdomain.com;  #Africa
  AS      as.yourdomain.com;  #Asia
  EU      eu.yourdomain.com;  #Europe
  # NA      www.yourdomain.com;  #North America
  OC      as.yourdomain.com;  #Oceania
  # SA      www.yourdomain.com;  #South America
}

欧洲服务器:

map $geoip_city_continent_code $closest_server {
  default eu.yourdomain.com;

  # AF      eu.yourdomain.com;  #Africa
  AS      as.yourdomain.com;  #Asia
  # EU      eu.yourdomain.com;  #Europe
  NA      www.yourdomain.com;  #North America
  OC      as.yourdomain.com;  #Oceania
  SA      www.yourdomain.com;  #South America
}

亚洲服务器:

map $geoip_city_continent_code $closest_server {
  default as.yourdomain.com;

  AF      eu.yourdomain.com;  #Africa
  # AS      as.yourdomain.com;  #Asia
  EU      eu.yourdomain.com;  #Europe
  NA      www.yourdomain.com;  #North America
  # OC      as.yourdomain.com;  #Oceania
  SA      www.yourdomain.com;  #South America
}

那应该这样做......

您还可以通过在正文中添加包含以下代码的 test.php 文件来测试您的设置:

<?php
if (getenv(HTTPXFORWARDEDFOR)) {
  $pipaddress = getenv(HTTPXFORWARDEDFOR);
  $ipaddress = getenv(REMOTEADDR);
  echo "Your Proxy IP address is : ".$pipaddress. " (via $ipaddress) " ;
} else {
  $ipaddress = getenv(REMOTEADDR);
  echo "Your IP address is : $ipaddress";
}
$country = getenv(GEOIPCOUNTRYNAME);
$countrycode = getenv(GEOIPCOUNTRYCODE);
$geoip_city_continent_code = getenv(GEOIP_CITY_CONTINENT_CODE);
echo "<br/>Your country : $country ( $countrycode ) ";
echo "<br/>Your continent : $geoip_city_continent_code ";
?>

应该返回如下内容:

Your IP address is : 12.34.56.78
Your country : United States ( US )
Your continent : NA

如果您在美国并将您重新路由到 www.yourdomain.com 等......

编辑 2 - 用于多站点处理

它的结构是为不同的服务器提供子域的国家代码，在这种情况下，us.domain.com 用于美国服务器......

map $geoip_city_continent_code $closest_server {
  AF      eu.domain.com;  #Africa
  AS      as.domain.com;  #Asia
  EU      eu.domain.com;  #Europe
  NA      us.domain.com;  #North America
  OC      as.domain.com;  #Oceania
  SA      us.domain.com;  #South America
}

# retoute http://domain.com and http://www.domain.com to http://us.domain.com
server {

  listen 80 default_server; # only for one of the local domains other wise the others should only be: listen 80;
  listen [::]:80 default_server ipv6only=on; # only for one of the local domains other wise the others should only be: listen [::]:80;

  server_name domain.com
              www.domain.com;

  return 301 http://us.domain.com$request_uri;
}

# handles
server {
  listen 80;
  listen [::]:80;

  root /var/www/domain.com/html;
  index index.php index.html index.htm;

  # Make site accessible from http://localhost/
  server_name  us.domain.com;

  # firs part of dual condition check.
  # checks in the incoming host (us.domain.com) is not equal to $closest_server depending on contry code
  if ($closest_server != $host) {
    set $test  A;
  }

  #second part of dual condition checks that the incoming host us.domain.com is the same as the server_name so that there is no messing around with other domain names
  if ($host ~* $server_name) {
    set $test  "${test}B";
  }

  # checks that the above 2 conditions are met and if so redirect to other global server with appropriate subdomain eu.domain.com or whatever you set up
  if ($test = AB) {
    rewrite ^ $scheme://$closest_server$request_uri break;
  }

  # otherwise you are at the closest server and so serve the data
  location / {
    try_files $uri $uri/ =404;
  }
