Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Purchase the cert

This is a sample of how to send some information to logstash via the TCP input in nodejs or python. It assumes the logstash host is on 10.10.10.100 and the TCP listening input is 9563.

The logstash.conf should look something like the sample file.

The log message should be a stringified JSON object with the log message in the @message field.

To use, run the node script node sendMessageToLogstash.js, or the python script python sendMessageToLogstash.js

The program below can take one or more plain text files as input. It works with python2 and python3.

Let's say we have two files that may contain email addresses:

file_a.txt

foo bar
ok [email protected] sup
 [email protected],wyd
hello world!
