MyMind + Mindmaps

Initial Setup

We're going to setup a debian CT on proxmox:


root@mindmaps:~# wget https://raw.githubusercontent.com/ech1/serverside/master/ssh/ssh.sh ; chmod +x ssh.sh ; ./ssh.sh

This will setup key-based SSH authentication, generate the ssh keys and go get them on port 8080:


Generating public/private ed25519 key pair.
Enter file in which to save the key (/root/.ssh/id_ed25519): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_ed25519.
Your public key has been saved in /root/.ssh/id_ed25519.pub.
The key fingerprint is:
SHA256:IubhhdBEfOjtKdMtfjIDgVl/7MYOSZ3WQTRzqN1s7p0 root@mindmaps
The key's randomart image is:
+--[ED25519 256]--+
|   oo.   o=..    |
|   o+ .   o+     |
|  .=.+ o = +     |

root@mindmaps:~# apt install nginx git -y

Configuring NGINX

We're going to setup a very simple nginx setup for our local host:


root@mindmaps:~# vim /etc/nginx/sites-available/mindmaps.conf
	
server {
        listen 80;
        listen [::]:80;
        root /var/www/html/mymind;
	index index.html;
}

:wq

root@mindmaps:~# ln -s /etc/nginx/sites-available/mindmaps.conf /etc/nginx/sites-enabled/

root@mindmaps:~# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

root@mindmaps:~# nginx -s reload

Now that's done, let's git clone the mymind repository into /var/www/html/:


root@mindmaps:/var/www/html# git clone https://github.com/ondras/my-mind mymind
root@mindmaps:/var/www/html# chmod -R 655 mymind/
root@mindmaps:/var/www/html# chown -R www-data: mymind/
root@mindmaps:/var/www/html# ls -lash mymind/

Once that's done, goto http://10.0.0.171/ to see the result:

After creating mindmaps you can save them:

And load them:

And that's it! However let's check out another interesting mindmapping HTML CSS JS project simply called mindmaps. We're going to update the nginx config to have port 8080 serve a http reverse proxy to http://localhost:3000 (where the npm server outputs) with the root path being in /var/www/html/mindmaps:

First we're going to install npm and clone the repository in /var/www/html/:


root@mindmaps:/var/www/html# apt install npm -y
	
root@mindmaps:/var/www/html# git clone https://github.com/drichard/mindmaps

Resolving deltas: 100% (2066/2066), done.

Once that's done, go in the repository directory to install the required dependencies:


root@mindmaps:/var/www/html# cd mindmaps/
root@mindmaps:/var/www/html/mindmaps# npm install
root@mindmaps:/var/www/html/mindmaps# npm run build

Hit CTRL-C to stop the server

Same as before, you can save and import your mindmaps:

Now let's CTRL+C to shutdown the npm server, and edit the nginx config:


^C
root@mindmaps:/var/www/html/mindmaps# vim /etc/nginx/sites-available/mindmaps.conf
	
upstream backend {
        server 127.0.0.1:3000;
}

server {
        listen 80;
        listen [::]:80;
        root /var/www/html/mymind;
        index index.html;
}

server {
        listen 8080;
        listen [::]:8080;
        location / {
                proxy_pass http://backend;
                proxy_http_version 1.1;
        }
}

:wq

Now let's get the systemd service file that will run npm for us because we don't want to manually launch a webserver in a production environnement:


root@mindmaps:/var/www/html/mindmaps# vim /etc/systemd/system/mindmap.service

Now that's done, we can reload our nginx server to see the config changes:


root@mindmaps:/var/www/html/mindmaps# nginx -s reload

And that's it! We managed to create a nginx reverse proxy to access our mindmaps npm http server via port 8080.
