Linux Nginx负载平衡器，具有两个负载平衡的Nginx+；php fpm（主脚本未知）错误

我们有两台带有nginx+php fpm（10.0.0.10和10.0.0.20）的web服务器，它在另一台nginx服务器（仅为nginx）后面进行负载平衡，当我们尝试浏览时，会发现文件未找到错误，错误日志列在底部

负载平衡器（10.0.0.1）

nginx.conf

upstream test_rack {
    server 10.0.0.10:80;
    server 10.0.0.20:80;
}

server {
    location / {
       proxy_pass http://test_rack;
     }
}}

上游服务器（10.0.0.20）

subdomains.conf

server {
listen       80;
server_name ~^(?<sub>.+)\.example\.com$;

root /data/vhost/$sub.example.com/htdocs;

location / { 
    try_files $uri /index.php;
 }


location ~ \.php$ {
    fastcgi_pass   unix:/var/run/php5-fpm.sock;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME   $document_root$fastcgi_script_name;
    include        fastcgi_params;
}}

添加

proxy\u set\u头主机$Host到第一个nginx

否则，您的上游将获得
test\u rack
，而不是原始主机名，
$sub
变量为空
