NodeJSBlog

This is a personal blog where I write about everything from projects to tutorials on sophisticated machine learning algorithms. If you want to stay up to date with new posts, subscribe to my RSS feed.

This project is a custom express application that uses pandoc to render latex/markdown files as HTML pages. This site has its very own admin portal to manage posts and downloads.

Dependencies

• mysql
• node + npm
• pandoc
• nxinx (for https)

Running

Installing the node-dependencies is as easy as running the npn install command:

npm install

All configurations are currentl found in the config.json file. In this file you specify things like port, sql connection, etc.

There is a provided bash script that will run the application

chmod +x run.sh
./run.sh

For deployment I used a Nginx proxy to expose the node application running on port 8000 to port 80. This proxy is necessary because you can't run a node application as port 80 unless you are root, which would be a security vulnerability.

Running with Docker

To simplify development and deployment you can run the entire node blog and mysql server from docker using docker-compose.

docker-compose up

or

docker-compose up db
docker-compose up blog

To Access mysql server of docker daemon for maintenence. Note: you need to configure username and password in docker-compose.yml and config.json.

mysql --port=3306 --host=127.0.0.1 -u root --password=password

NGINX Configuration

#jrtechs.net.conf
server 
{
    listen 80;
    server_name www.jrtechs.net jrtechs.net;

    # redirect http requests to https
    return 301 https://jrtechs.net$request_uri;
}

server 
{
    listen 443 ssl http2;

    server_name jrtechs.net;

    ssl_certificate /etc/letsencrypt/live/jrtechs.net/cert.pem;
    ssl_certificate_key /etc/letsencrypt/live/jrtechs.net/privkey.pem;

    location / {
        proxy_pass http://localhost:8000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Projects Sites

As I develop more projects I would like an easy way to add and host them on my website without having to create another sub-domain and generate more ssl certs. I simply want the project site to be accessible under https://jrtechs.net/project_name.

State Diagram of Plan

DB Backup and Restore

This will dump everything in the database to a plain text file. A base SQL schema can be found in docs//sqlConfig.md

sudo mysqldump -u [user] -p [database_name] > [filename].sql

This will take a database dump and load it into a active mysql instance. Note: the database (can be empty) must already exist.

sudo mysql -u [user] -p [database_name] < [filename].sql
