Currently, I am trying to configure the https for one of my tomcat which is under ELB and for SSL certificate I have used aws certificate manager and pointed to the ELB.
My Elb listeners ports are
ELB port 80 ---> Instance port --> 8080
ELB port 443 --> Instance port --> 8080 with ACM certificate.
Is any configuration that needs to be in tomcat level or any method to run my site with https using ACM?
Your can put NGNIX in each tomcat instance , Nginx is super reliable and has the smallest footprint I ever seen in a serious web server.
Then in NGNIX Config
NGINX will rewrite all requests to the ELB calling the HTTPS port utilizing status 301.
server {
listen 80;
server_name myhost.com;
# add ssl settings
return 301 https://myhost.com$request_uri;
}
Tomcat Config:
Now you need to touch the server.xml configuration of Tomcat (located # $TOMCAT/conf/server.xml) .
<Connector scheme="https" secure="true" proxyPort="443"
port="8080" protocol="HTTP/1.1"
connectionTimeout="25000"
URIEncoding="UTF-8"
redirectPort="8443" />
Amazon Elastic Load Balancer:
You have to configure in the AWS ELB the following listeners.
HTTP 80 -> HTTP 80 (nginx)
HTTPS 443 -> HTTP 8080 (tomcat)
I hope this works for you.

I remember doing it before but now it seems I have forgotten the process.
I want to create an HTTPS listener for an ALB. However, I don't have anything in my ec2 running on 443.
Should I configure a reverse proxy which points 443 to the app running port or add my HTTPS listener with port 80 HTTP target group?
Could someone help me with this?
You need a single Target Group pointing to your EC2 instance on port 80.
Then you can create a port 443 listener on the ALB that uses that target group. You will have to attach an SSL certificate to the listener when you create it. The ALB will terminate the SSL connection and send the request to the backend server over port 80.
I recently had to update my SSL certificate for my AWS Elasticbeanstalk. After the SSL certificate was updated, it started returning HTTP 503 error if I use HTTPS. It used to work fine earlier with HTTPS.
Finally figured out that when I changed my SSL certificate, the HTTPS out port 443 was some how mapped to inbound 443 port instead of port 80. All communication between load balancer and EC2 happens on HTTP on port 80. The load balancer which takes requests from external internet takes the HTTPS on port 443. So ensure the internal port mapping is 80 with HTTP and external is 443 with HTTPS
I have two docker containers in beanstalk instances, One listen on port 80, another one listen port 8080. The security group allows port 80,8080. I can access url on port 80 and 8080 using http. I want to use https. I have created a certificate in ACM. Updated the load balancer in beanstalk env as below. but now i can not access website using https.ImagePorts
You need to https listener in your Load balancer, from the image the protocol is https but the port is 80
Create an https listener in LB
Map 443 of LB with 80 of the target
allow 443 in the SG of LB
instance port should be 80. As the SSL traffic decrypt before sending to the target.
If you are interested to add SSL with 8080 then you need to specify certificate with 8080 as well.
I have ELB setup in AWS
1. TCP port 443 forward to 8080 port on instance (nginx)
2. www.example.com point to ELB dns
3. myserver.mydomain is my instance hostname
Now i have setup ssl on ELB for domain www.example.com
Now for ssl on nginx so that all communication is ssl. I want o know that
DO i need to upload ssl on nginx for www.example.com or myserver.mydomain or its IP adddress
Ok as per your comment if you want the SSL from the server side too. Then this are the two steps you need to follow.
Upload SSL for "www.example.com" on you server and configure nginex to server 443 port.
Change the ELB listeners from 443-80 to 443-443.
And it will work
I am running NodeJS app on EC2 instance on port 3000 without having any apache or nginx. I have setup ELB at front with SSL enabled( ACM on ELB ). Now I want to open my web-app url with https always.I have redirected port 443 request to port 3000 which is open on https. Same I want to do with port 80 request to go with 443 and then finally end up to port 3000, Because if someone request with port 80 for the web-app url that should also redirect to https and then end up on port 3000.
So Can you tell me How can I implement on ELB this thing for port 80 request which also open with https. My port 3000 is on http on EC2 instance.
port 443 https ----> port (3000) http ( its working )
port 80 (http) ---->want to open with https(443 ) ----->port(3000 ) http (this I want to implement)
I'm afraid ELB doesn't have built in support for this feature. It's something your web app would need to deal with.
You could set the ELB to forward port 80 to port 3000 too, and then in your app you'd need to inspect the X-Forwarded-Proto header; if this is not https then you would issue a redirect to port 443.
Amazon's X-Forwarded Docs
for solution to this, we need to run something on port 80 that could be sample nodeJS app or any default web-page(html or php) and then redirect port 80 request to port 443 and port 443 will redirect to port 3000(setup inside aws ELB) which is running actual NodeJS app.
