Redirect Loop

[John Hanson]

Hello all,

I am rebuilding our ad server and am having some issues with a redirect loop. The site is being hosted via nginx and php-fpm. Here is the nginx config file:

upstream php {
        server unix:/var/run/php5-fpm.sock;
}

server {
    listen 80;
    server_name name.example.com;
    client_max_body_size 16M;
    client_header_buffer_size 16k;
    large_client_header_buffers 16 256k;
    set $root_dir "/var/web/revive-adserver/www";
    root $root_dir;
    charset utf-8;
    access_log /var/log/nginx/name.example.com_access.log sk_combined;
    error_log /var/log/nginx/name.example.com_error.log;

    location / {
        index index.php;
        gzip on;
        gzip_vary on;
        root $root_dir;
        try_files $uri $uri/ /index.php;
    }

    location ~ ^/fpm-(status|ping)$ {
            access_log off;
            allow 127.0.0.1;
            allow 10.0.0.0/8;
            allow 172.16.0.0/16;
            allow 192.168.0.0/16;
            deny all;
            include fastcgi_params;
            fastcgi_pass php;
    }

    location ~ ^/admin$ {
            access_log off;
            allow 127.0.0.1;
            allow 10.0.0.0/8;
            allow 172.16.0.0/16;
            allow 192.168.0.0/16;
            deny all;
            include fastcgi_params;
            fastcgi_pass php;
    }

    location ~ \.php$ {
        fastcgi_index index.php;
        fastcgi_split_path_info ^(.+.php)(/.+)$;
        fastcgi_pass php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        try_files $uri $uri/ =404;
    }
}

The site worked great in testing (a.k.a without the existing database) but seems to just end up in a redirect loop between admin/index.php and admin/install.php:

I can provide further config files if needed but is there an easy way to stop the redirects?

I would try it without the 

        try_files $uri $uri/ /index.php;

config parameter. Apart from that it's quite a weird redirect loop that you have there. Are you rewriting any hostname or something ? Revive seems to think it's not installed on that domain.
