Installation

Hi,

Please https://forum.netdivo.com is not opening

How can I know what is wrong?

The server is running and I have restarted it several times.

Your Ping goes to request timed out.

This can be due to a firewall preventing connections to your server or discourse not running.

Can you ssh into your server and do

cd /var/discourse
docker ps

It will give you an output to verify if your discourse container is actually running or not.

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/r
un/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/containers/json: dial unix /va
r/run/docker.sock: connect: permission denied

Pls, how do I resolve this?

Are You performing this as root? If not then try

sudo docker ps

If it still reports the same issue then Your docker is probably not running. You’ll need to find out how docker was installed to restart it.

running it as root did not throw the error.

Discourse isn’t running try this:

cd /var/discourse
./launcher start app

Please run

You have apache2 running on Your server, it needs to be stopped and uninstalled before you could start discourse docker.

Try

service apache2 stop
apt purge apache* -y
cd /var/discourse
./launcher start app
12

thanks but the purge command threw this error :

purge

Append sudo to the command e.g.:

sudo -i
service apache2 stop
apt purge apache* -y
cd /var/discourse
./launcher start app
