Replace the SSL certificate for your Classic Load Balancer

If you have an HTTPS listener, you deployed an SSL server certificate on your load balancer when you created the listener. Each certificate comes with a validity period. You must ensure that you renew or replace the certificate before its validity period ends.

Certificates provided by AWS Certificate Manager and deployed on your load balancer can be renewed automatically. ACM attempts to renew certificates before they expire. For more information, see Managed renewal in the AWS Certificate Manager User Guide. If you imported a certificate into ACM, you must monitor the expiration date of the certificate and renew it before it expires. For more information, see Importing certificates in the AWS Certificate Manager User Guide. After a certificate that is deployed on a load balancer is renewed, new requests use the renewed certificate.

To replace a certificate, you must first create a new certificate by following the same steps that you used when you created the current certificate. Then, you can replace the certificate. After a certificate that is deployed on a load balancer is replaced, new requests use the new certificate.

Note that renewing or replacing a certificate does not affect requests that were already received by a load balancer node and are pending routing to a healthy target.

Replace the SSL certificate using the console

You can replace the certificate deployed on your load balancer with a certificate provided by ACM or a certificate uploaded to IAM.

To replace the SSL certificate for an HTTPS load balancer using the console

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. On the navigation pane, under Load Balancing, choose Load Balancers.

  3. Choose the name of the load balancer to open its detail page.

  4. On the Listeners tab, choose Manage listeners.

  5. On the Manage listeners page, locate the listener to be updated, choose Edit under Default SSL cert and do one of the following:

    • If you created or imported a certificate using AWS Certificate Manager, choose From ACM, select the certificate from the list, and then choose Save changes.

      Note

      This option is available only in Regions that support AWS Certificate Manager.

    • If you imported a certificate using IAM, choose From IAM, select the certificate from from the list, and then choose Save changes.

    • If you have an SSL certificate to import to ACM, select Import and To ACM. In Certificate private key, copy and paste the contents of the PEM-encoded private key file. In Certificate body, copy and paste the contents of the PEM-encoded public key certificate file. In Certificate chain - optional, copy and paste the contents of the PEM-encoded certificate chain file, unless you are using a self-signed certificate and it's not important that browsers implicitly accept the certificate.

    • If you have an SSL certificate to import but ACM is not supported in this Region, select Import and To IAM. In Certificate name type the name of the certificate. In Certificate private key, copy and paste the contents of the PEM-encoded private key file. In Certificate body, copy and paste the contents of the PEM-encoded public key certificate file. In Certificate chain - optional, copy and paste the contents of the PEM-encoded certificate chain file, unless you are using a self-signed certificate and it's not important that browsers implicitly accept the certificate.

    • Choose Save changes.

Replace the SSL certificate using the AWS CLI

You can replace the certificate deployed on your load balancer with a certificate provided by ACM or a certificate uploaded to IAM.

To replace an SSL certificate with a certificate provided by ACM

  1. Use the following request-certificate command to request a new certificate:

    aws acm request-certificate --domain-name www.example.com

  2. Use the following set-load-balancer-listener-ssl-certificate command to set the certificate:

    aws elb set-load-balancer-listener-ssl-certificate --load-balancer-name my-load-balancer --load-balancer-port 443 --ssl-certificate-id arn:aws:acm:region:123456789012:certificate/12345678-1234-1234-1234-123456789012
To replace an SSL certificate with a certificate uploaded to IAM

  1. If you have an SSL certificate but have not uploaded it, see Uploading a server certificate in the IAM User Guide.

  2. Use the following get-server-certificate command to get the ARN of the certificate:

    aws iam get-server-certificate --server-certificate-name my-new-certificate

  3. Use the following set-load-balancer-listener-ssl-certificate command to set the certificate:

    aws elb set-load-balancer-listener-ssl-certificate --load-balancer-name my-load-balancer --load-balancer-port 443 --ssl-certificate-id arn:aws:iam::123456789012:server-certificate/my-new-certificate
