Nginx 负载均衡器有两个负载均衡 nginx+php-fpm (Primary script unknown) 错误

Nginx Load Balancer having two load balanced nginx+php-fpm (Primary script unknown) error

我们有两个带有 nginx+php-fpm 的 Web 服务器(10.0.0.10 和 10.0.0.20),它们在另一个 nginx 服务器(仅 nginx)之后进行负载平衡,当我们尝试浏览时我们得到文件未发现错误,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;
}}     

网络服务器(10.0.0.10 和 10.0.0.20)出错

*1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 10.0.0.1, server: ~^(?<sub>.+)\.example\.com$, request: "GET / HTTP/1.0", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "test_rack"

尝试过的解决方案:

fastcgi_param  SCRIPT_FILENAME   /data/vhost/$sub.example.com/htdocs/$fastcgi_script_name;

proxy_set_header Host $host; 添加到第一个 nginx。

否则您的上游得到 test_rack 而不是原始主机名,并且 $sub 变量为空。
