Use the following steps to configure Nginx Plus as the load balancer for WSO2 products.

Install Nginx Plus in a server configured in your cluster.

Configure Nginx Plus to direct the HTTP requests to the two worker nodes via the HTTP 80 port using the http://as.wso2.com/<service>. To do this, create a VHost file (as.http.conf) in the /etc/nginx/conf.d/ directory and add the following configurations into it.

Code Block

upstream wso2.as.com {
        sticky cookie JSESSIONID;
        server xxx.xxx.xxx.xx3:9763;
        server xxx.xxx.xxx.xx4:9763;
}

server {
        listen 80;
        server_name as.wso2.com;
        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;
               proxy_pass http://wso2.as.com;
        }
}

Configure Nginx Plus to direct the HTTPS requests to the two worker nodes via the HTTPS 443 port using https://as.wso2.com/<service>. To do this, create a VHost file (as.https.conf) in the /etc/nginx/conf.d/ directory and add the following configurations into it.

Code Block

upstream ssl.wso2.as.com {
	sticky cookie JSESSIONID;
	server xxx.xxx.xxx.xx3:9443;
	server xxx.xxx.xxx.xx4:9443;
}

server {
listen 443;
	server_name as.wso2.com;
	ssl on;
	ssl_certificate /etc/nginx/ssl/wrk.crt;
	ssl_certificate_key /etc/nginx/ssl/wrk.key;
	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;
	    proxy_pass https://ssl.wso2.as.com;
    	}
}

Configure Nginx Plus to access the Management Console as https://mgt.as.wso2.com/carbon via HTTPS 443 port. This is to direct requests to the manager node. To do this, create a VHost file (mgt.as.https.conf) in the /etc/nginx/conf.d/ directory and add the following configurations into it.

Code Block

server {
	listen 443;
	server_name mgt.as.wso2.com;
	ssl on;
	ssl_certificate /etc/nginx/ssl/mgt.crt;
	ssl_certificate_key /etc/nginx/ssl/mgt.key;

	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;
	    proxy_pass https://xxx.xxx.xxx.xx2:9443/;
    	}
	error_log  /var/log/nginx/mgt-error.log ;
           access_log  /var/log/nginx/mgt-access.log;
}

Restart the Nginx Plus server.
$sudo service nginx restart
Tip
Tip: You do not need to restart the server if you are simply making a modification to the VHost file. The following command should be sufficient in such cases.
$sudo service nginx reload
