Hello,I opened a Digital Ocean Ubuntu server with Docker and the followed the instructions to install OpenMRS on the server. Installen Maven and JAVA. Installation process completed with success. However, I struggle to connect to the webserver through the IP address. The IP address is 174.138.8.224 And the port should be 8080.

Can anyone here help me to fix this?

Is this your external IP address for your docker instance ? doesn’t look responsive and port doesn’t look open

Okay. I added port 8080 to the ports.conf file in apache2. How do I now make it open openmrs? It now goes to the apache2 landing page.

> followed the instructions to install OpenMRS on the server

Which instructions have you followed? You shouldn’t need to add port 8080 to Apache. OpenMRS is served through a servlet container such as Tomcat. You could use Apache as a reverse proxy for the Tomcat container, e.g., using instructions like those [here](https://cwiki.apache.org/confluence/display/HTTPD/TomcatReverseProxy), e.g.,

```auto
# mod_proxy setup.
ProxyRequests Off
ProxyPass /openmrs http://localhost:8080
ProxyPassReverse /openmrs http://localhost:8080

<Location "/openmrs">
  # Configurations specific to this location. Add what you need.
  # For instance, you can add mod_proxy_html directives to fix
  # links in the HTML code. See link at end of this page about using
  # mod_proxy_html.

  # Allow access to this proxied URL location for everyone.
  Order allow,deny
  Allow from all
</Location>

```

But that assumes that OpenMRS is installed an running on port 8080, which doesn’t seem to be the case for you.

Thank you, but it is very strange. I follow the instructions as it is given and it just does not connect. Which installation instructions should I follow if I want to install it on a cloud server like digital ocean. In other words, which virtual machine do I setup, etc.? Cause somewhere I must be doing something wrong. I prefer the docker container. I started over and just started the docker container with the following command on a new system: docker run -d --name openmrs -p 80:8080 openmrs/openmrs-reference-application-distro

ip address: [http://167.99.43.224:8080/openmrs](http://167.99.43.224:8080/openmrs)

Still no refusing to connect. If I ping the ip address it works.

</div>

So a few notes here:

1. You also need to start the MYSQL Docker image.
2. In your command to start the openmrs-reference-application-distro, you specify `-p 80:8080` that says “bind the server port 80 to port 8080 from the container”. Since you’re apparently already running Apache which is likely using port 80, that’s unlikely to work.
3. For a better method of installing this via Docker, please see Option 3 on [this Wiki page](https://wiki.openmrs.org/display/docs/Installing+OpenMRS+on+Docker).

Hello, I eventually managed with the SDK. And used Docker for the database. Now it seems to be working. Thank you

This was the error code flagged

Only thing I can gather is maybe the virtual machine does not have enough memory. How much is advised? This one has 2gb

changed it to 4gb and now it is working.

Is it possible to run it as a service so that it does not stop when I exit the terminal?
