Setting up secure HTTP with AMP

Greelan edited this page Jan 24, 2020 · 17 revisions

There are a number of methods that can be used to set up secure HTTP (HTTPS) within AMP depending on your use case.

Note that with AMP Enterprise, use of HTTPS is mandatory.

Reverse proxy via nginx (Recommended, Linux only)

If you use the default setup script, this is handled for you automatically. If you need to do this after the fact, then you simply run the following as root:

ampinstmgr setupnginx 8080

Where 8080 is the port that ADS is currently bound to. This will automatically configure nginx and run certbot to secure the domain. Before running the command ensure that the packages nginx, certbot and python-certbot-nginx are installed, otherwise the command will fail.

Also, you need port 80 forwarded and allowed through any firewall for certbot to be able to install the certificate. And of course port 443 must be forwarded and allowed through any firewall to access AMP externally via HTTPS, when this method is used.

If possible, it's highly desirable to let AMP set up the nginx reverse proxy for you. However, if your use case does not support that, see the manual setup instructions below.

Internal HTTPS implementation

AMP has built in support for HTTPS with its internal application server. AMP requires a certificate in PFX format with a passphrase. You can use ampinstmgr convertcertificate to convert a standard .cert + .key file pair into a PFX on Linux systems.

The main advantage is that no additional software is required, however it's not suitable for use with LetsEncrypt as AMP has to be restarted to swap out the certificate.

Linux Manual Configuration

This method is optimal if you already have your certificate in use with another webserver already.

Open /home/amp/.ampdata/instances/ADS01/AMPConfig.conf while ADS is stopped and edit the following lines:



Install the certificate to your system into the local machine store, and then view the certificate to get its serial number. Once you've done this edit the following lines to your AMPConfig.conf file for ADS:


Re-configuring existing instances

When using AMP’s built in HTTPS support, all existing instances other than ADS01 will need their authentication server updated to your ADS installations new URL.

Your login section for AMPConfig.conf for each instance should look like this, make sure to change to your chosen domain.

# Login
# Login.AuthServerURL - The URL for the ADS instance providing authentication when using UseAuthServer

Where 8080 is the port that ADS is currently bound to. Also in ADS, under Configuration -> New Instance Defaults you need to update the Default Auth Server URL to be the new URL of your ADS installation.

Manual nginx reverse proxy setup (advanced)

You may have a use case where you want to use an nginx reverse proxy but would prefer that AMP not set it up for you - for example, where you already have a certificate for your domain (such as a wildcard), or you prefer to use a tool other than certbot (such as to manage your certificates. In that case, you can configure things manually.

nginx configuration

The following nginx virtual host configuration is based on what AMP and certbot would generate. It can be included as /etc/nginx/conf.d/EXAMPLE.DOMAIN.COM.conf, or alternatively (on Debian and Ubuntu hosts) in /etc/nginx/sites-available and symlinked to /etc/nginx/sites-enabled. Either way, ensure that the relevant directory has an include directive in /etc/nginx/nginx.conf.

server {
    listen 80;
    listen [::]:80;
    server_name EXAMPLE.DOMAIN.COM;

    if ($host = EXAMPLE.DOMAIN.COM) {
        return 301 https://$host$request_uri;

    return 404;

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name EXAMPLE.DOMAIN.COM;

    # Replace the below as appropriate according to certificate locations and
    # whatever SSL settings you want. The below reflects a standard cerbot
    # configuration
    ssl_certificate /etc/letsencrypt/live/EXAMPLE.DOMAIN.COM/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/EXAMPLE.DOMAIN.COM/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
    location / {
        proxy_pass http://localhost:8080;  # Or whatever port ADS is listening on
        proxy_set_header        Host $host;
        proxy_set_header        X-Real-IP $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header        Upgrade $http_upgrade;
        proxy_set_header        Connection "Upgrade";
        proxy_set_header        X-AMP-Scheme $scheme;
        proxy_read_timeout      86400s;
        proxy_send_timeout      86400s;
        proxy_http_version      1.1;
        proxy_redirect          off;
        proxy_buffering         off;
        client_max_body_size    10240M;
        error_page 502 /NotRunning.html;

        location = /NotRunning.html {
            root /opt/cubecoders/amp/shared/WebRoot;

AMP configuration changes

The ADS must be stopped before making the following changes.

First (as the amp user):

ampinstmgr reconfigure ADS01 +Core.Webserver.UsingReverseProxy True

Then, if the nginx reverse proxy is not on the same host as the ADS, set the right IP (eg

ampinstmgr reconfigure ADS01 +Core.Webserver.ReverseProxyHost INSERT_IP
You can’t perform that action at this time.
