Set up WSO2 clusters with Nginx¶

When setting up the MWARE IAM cluster with Nginx, follow the instructions given below.

Note

Follow the instructions given below only after setting up the cluster following the Deployment Patterns.

Tip

When clustering MWARE IAM with a load balancer, you may need to enable sticky sessions. This is required for the MWARE IAM Management Console and My Account to work and if we disable temporary session data persistence in the <IS_HOME>/repository/conf/deployment.toml file.

Following is the deployment diagram with the load balancer.

Deployment with the loadbalancer

Configure Nginx¶

Use the following steps to configure NGINX Plus version 1.7.11 or nginx community version 1.9.2 as the load balancer for WSO2 products. (In these steps, we refer to both versions collectively as "Nginx".)

Install Nginx (NGINX Plus or nginx community) in a server configured in your cluster.

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

        proxy_redirect https://xxx.xxx.xxx.xx4:9443/oauth2/userinfo https://is.wso2.com/oauth2/ userinfo;
    }
}

Now that you've configured HTTP requests, you must also configure HTTPS requests. Configure Nginx to direct the HTTPS requests to the two worker nodes via the HTTPS 443 port using https://is.wso2.com/ . To do this, create a VHost file ( is.https.conf ) in the /etc/nginx/conf.d directory and add the following configurations into it.

Note

The configurations for nginx community version and NGINX Plus are different here since the community version does not support the sticky directive.

nginx Community Version

upstream ssl.wso2.is.com {
    server xxx.xxx.xxx.xx3:9443;
    server xxx.xxx.xxx.xx4:9443;
    ip_hash;
}

server {
listen 443;
    server_name is.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.is.com;

            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
        }
}

NGINX Plus

    upstream ssl.wso2.is.com {
        server xxx.xxx.xxx.xx3:9443;
        server xxx.xxx.xxx.xx4:9443;

                sticky learn create=$upstream_cookie_jsessionid
                lookup=$cookie_jsessionid
                zone=client_sessions:1m;
    }

    server {
    listen 443;
        server_name is.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.is.com;

                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
            }
    }

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

Management Console configurations

    server {
        listen 443;
        server_name mgt.is.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/;

                   proxy_http_version 1.1;
                   proxy_set_header Upgrade $http_upgrade;
                   proxy_set_header Connection "upgrade";
            }
        error_log  /var/log/nginx/mgt-error.log ;
               access_log  /var/log/nginx/mgt-access.log;
    }

Reload the Nginx server.
$sudo service nginx reload
Tip

If you have made modifications to anything other than the VHost files, you may need to restart the Nginx server instead of reloading it.
```
$sudo service nginx restart
```
