Missing Load Balancer Configuration

[isharailanga]

The Configuring the Proxy Server and the Load Balancer doc needs more ngnix.conf configurations

Under HA for Gateway all these configs are required. The doc is missing a few:

upstream sslgw1.am.wso2.com {
    server 192.xxx.xxx.xx:9443;
    server 192.xxx.xxx.xx:9444;
    #ip_hash;
    sticky learn create=$upstream_cookie_jsessionid
        lookup=$cookie_jsessionid
    zone=client_sessions:1m;
}

upstream <lb_hostname> {
    server 192.xxx.xxx.xx:8243;
    server 192.xxx.xxx.xx:8244;
}

server {
    listen 80;
    server_name sslgw1.am.wso2.com;
    rewrite ^/(.*) https://sslgw1.am.wso2.com/$1 permanent;
}

server {
    listen 443 ssl;
    server_name <server_name>;
    proxy_set_header X-Forwarded-Port 443;
    ssl_certificate /etc/nginx/ssl/server.crt;
    ssl_certificate_key /etc/nginx/ssl/server.key;
    large_client_header_buffers 4 32k;
    location / {
            proxy_set_header X-Forwarded-Host $host;
            proxy_set_header X-Forwarded-Server $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_read_timeout 5m;
            proxy_send_timeout 5m;
            fastcgi_buffers 16 16k;
            fastcgi_buffer_size 38k;
            proxy_buffer_size   128k;
            proxy_buffers     4 256k;
            proxy_busy_buffers_size     256k;
            proxy_pass https://<lb_hostname>;
            proxy_redirect https://192.xxx.xxx.xx:9443 https://<lb_hostname>;
            proxy_redirect https://192.xxx.xxx.xx:9444 https://<lb_hostname>;
        }
}

• For more info, pls check https://docs.google.com/document/d/1IVNFdVPRKuSSfmlYDHUx4_4je-Wvhmc8qRYrjXnLMPk/edit# > point 6.4

• In the same doc, need to add more details regarding the logs (access_log, error_log) mentioned in the document. Because, when we specify the log path as mentioned in the doc, it gives a file missing error.

Adding help wanted tag to verify these configs for API-M.
