MySQL

Getting started

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

Remove MySQL completely

Open the Terminal
Use mysqldump to backup your databases
Check for MySQL processes with: ps -ax | grep mysql
Stop and kill any MySQL processes
Analyze MySQL on HomeBrew:
```
brew remove mysql
```

If you get error like this:

Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

	daemon off;

	worker_processes 1;

	events { worker_connections 1024; }

	http{

	sendfile on;

	INSTALL JAVA
	$ sudo apt-get update && sudo apt-get install default-jre

	INSTALL ELASTIC SEARCH https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-repositories.html
	$ wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch \| sudo apt-key add -
	$ echo "deb https://packages.elastic.co/elasticsearch/2.x/debian stable main" \| sudo tee -a /etc/apt/sources.list.d/elasticsearch-2.x.list
	$ sudo apt-get update && sudo apt-get install elasticsearch
	$ sudo update-rc.d elasticsearch defaults 95 10
	$ sudo service elasticsearch restart
	$ sudo service elasticsearch status

	# [<tag>] (If applied, this commit will...) <subject> (Max 72 char)
	# \|<---- Preferably using up to 50 chars --->\|<------------------->\|
	# Example:
	# [feat] Implement automated commit messages

	# (Optional) Explain why this change is being made
	# \|<---- Try To Limit Each Line to a Maximum Of 72 Characters ---->\|

	# (Optional) Provide links or keys to any relevant tickets, articles or other resources
	# Example: Github issue #23

	# ~/.config/starship.toml

	[battery]
	full_symbol = "🔋"
	charging_symbol = "🔌"
	discharging_symbol = "⚡"

	[[battery.display]]
	threshold = 30
	style = "bold red"
