Port forwarding with ELB in AWS vs NginX

< requirement >

input 1 : http://aaa1.testdomain.com
internal service 1 : http://localhost:3000

input 2 : http://aaa2.testdomain.com
internal service 2 : http://localhost:3001

< 1. AWS approach >

1. create LoadBalancers
cf. https://console.aws.amazon.com/ec2/v2/home?region=us-east-1#LoadBalancers:
ㅇ create Load Balancer for 1st port
1. Define Load Balancer
Load Balancer name: aaa1-test
Load Balancer Port: 80
Instance Port: 3000
2. Configure Health Check
Ping Path: it's important!
3. Add EC2 Instances: Add EC2 Instances to Load Balancer
4. check out the domain and service
(1st Load Balancer's Description > DNS Name > A Record : ex) aaa1-test-1425011489.us-east-1.elb.amazonaws.com )
- test service : http://aaa1-test-1425011489.us-east-1.elb.amazonaws.com

ㅇ create Load Balancer for 2nd port
1. Define Load Balancer
Load Balancer name: aaa2-test
Load Balancer Port: 80
Instance Port: 3001
2. Configure Health Check
Ping Path: it's important!
3. Add EC2 Instances: Add EC2 Instances to Load Balancer
4. check out the domain and service
(2nd Load Balancer's Description > DNS Name > A Record : ex) aaa2-test-1425011489.us-east-1.elb.amazonaws.com )
- test service : http://aaa2-test-1425011489.us-east-1.elb.amazonaws.com

2. create route record sets
cf. https://console.aws.amazon.com/route53/home?region=us-east-1
Hosted zones > Create Hosted Zone
Domain Name: testdomain.com
ㅇ create domain for 1st Load Balancer
Hosted zones > Record Sets > create record set
name: aaa1.testdomain.com
cname: 1st Load Balancer's domain name ex) aaa1-test-1425011489.us-east-1.elb.amazonaws.com

ㅇ create domain for 2nd Load Balancer
Hosted zones > Record Sets > create record set
name: aaa2.testdomain.com
cname: 2nd Load Balancer's domain name ex) aaa2-test-1425011489.us-east-1.elb.amazonaws.com


< 2. Webserver approach - nginx >

sudo -i
apt-get update
apt-get install -y nginx
apt-get update


< Production >

* aws route 53 domain setting or get dns service
aaa1.testdomain.com. xxx.xxx.xxx.xxx  
aaa2.testdomain.com. xxx.xxx.xxx.xxx

/etc/nginx> sudo vi nginx.conf

    server {
        listen       80;
        server_name  aaa1.testdomain.com;
        location / {
            proxy_redirect     off;
            proxy_set_header   Host             $host;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For  $remote_addr;
            proxy_pass http://localhost:3000;
            index  index.html;          
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

    server {
        listen       80;
        server_name  aaa2.testdomain.com;
        location / {
            proxy_redirect     off;
            proxy_set_header   Host             $host;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For  $remote_addr;
            proxy_pass http://localhost:3001;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

$ sudo nginx
$ sudo nginx -s stop
