anthony's questions

I created 6 instances in Google Cloud Plateform

• 2 in asia
• 2 in us
• 2 in europe

I have 3 groups in each zone

When i try to go to my app, i'm randomly send to one zone, no matter if i'm in Europe or an other place.

For info, i followed this documentation https://cloud.google.com/compute/docs/load-balancing/http/cross-region-example

I just add one zone and remove http conf.

There is no traffic on the 6 instances, only me. All the 6 instances are available et health check are positif.

Here is my last result when i just refresh the page :

1. Asia
2. Europe
3. US
4. Europe
5. Asia
6. Asia

If you have any idea or if you need more details to help me, just ask, i will.

Update 1

In each instance i have one nginx with one default conf :

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name _;
    return 301 https://$host$request_uri;
}



server {
    listen 443 ssl;
    server_name _;
    ssl_certificate /etc/nginx/ssl/secure.crt;
    ssl_certificate_key /etc/nginx/ssl/mysecure.key;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }
}

Then i have my application conf :

server {
    listen 443 ssl;
    server_name myapp.example.com www.myapp.example.com;
    ssl_certificate /etc/nginx/ssl/secure.crt;
    ssl_certificate_key /etc/nginx/ssl/mysecure.key;

    root /usr/share/nginx/html/app/web;

    error_log /var/log/nginx/myapp.example.com_error.log;
    access_log /var/log/nginx/myapp.example.com.log;

    if ($http_x_forwarded_proto = "http") { 
        return 301 https://$host$request_uri; 
    }

    location / {
        # try to serve file directly, fallback to app.php
        try_files $uri /app.php$is_args$args;
    }
    # PROD
    location ~ ^/app\.php(/|$) {
        fastcgi_pass php:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME  $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;
        internal;
    }
}

When i go to https://ip-load-balancer, it's working perfectly, always get the closest instance.

But when i try https://myapp.example.com, it's goes wrong, i can see in the log that there is some redirect. Also when i check the log of the load balancer, he send the request to the good instance, but then i don't understand how to follow the request.

Thanks

i'm trying to configure a scalable symfony2 app, so i read this page https://cloud.google.com/compute/docs/load-balancing/http/cross-region-example

i did every thing like they said, is working with a simple nginx conf :

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.html index.htm;

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

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ /index.html;
            # Uncomment to enable naxsi on this location
            # include /etc/nginx/naxsi.rules
    }
}

with that i get a positive check health and if i try http://ip_load_balancer i get the nginx's default page.

But when i try my real nginx's conf:

server {
listen 80;
server_name myapp-public.com;
root /usr/share/nginx/html/app-public/web;


recursive_error_pages off;

error_log /var/log/nginx/app_error.log;
access_log /var/log/nginx/app_access.log;

location / {
    try_files $uri /app.php$is_args$args;
}

# PROD
location ~ ^/app\.php(/|$) {
    internal;
    fastcgi_pass php:9000;
    fastcgi_split_path_info ^(.+\.php)(/.*)$;
    fastcgi_index  index.php;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param HTTPS off;
    fastcgi_intercept_errors on;
}
}

When i try http://ip_load_blancer, i get 502 Server Error. But when i try http://ip_vm1, i get my application (i open the http access from all to test).

Also all the check health fail. I don't really understand what's wrong, any idea?

Thanks.
