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

Ubuntu 18.04 installation with LUKS and LVM

Installation Process

Pre-installation from live OS

This setup of Ubuntu with LUKS and LVM is tested on Ubuntu 18.04.

Boot Ubuntu from a Live OS and select the option to try Ubuntu without installing. Follow the steps I've outlined below. Let's assume you're installing to /dev/nvme0n1.

Partition the drive with your tool of choice: I used gparted to set mine up.

	#If you are receiving complaints against your server for outgoing xmlrpc brute-force attack, then you can easily find-out culprit account by using below steps:

	1) Run below command in 'Screen', it will dump all the monitored logs to /home/logs/tcpdump14022016 file.
	tcpdump -A -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)' > /home/logs/tcpdump14022016

	2) Set up below crons on the server. You can either set up these crons in the server crons i.e at crontab -e or you can set it up at /etc/cron.d/filename, for e.g. as in below case filename is "dumplogs".

	root@test[/etc/cron.d]# cat dumplogs
	* * * * * root /home/logs/writelogs.sh
	* * * * * root sleep 30; /home/logs/writelogs.sh

	# Run the last command as root
	sudo !!
	# Serve current directory tree at http://$HOSTNAME:8000/
	python -m SimpleHTTPServer
	# Save a file you edited in vim without the needed permissions
	:w !sudo tee %
	# change to the previous working directory
	cd -
	# Runs previous command but replacing
	^foo^bar
