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
server { | |
listen 80; | |
server_name domain.com.br; | |
location / { | |
proxy_set_header X-Real-IP $remote_addr; | |
proxy_set_header Host $host; | |
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; | |
proxy_pass http://127.0.0.1:8181; |
Example:
zsh-5.7.1-1-x86_64.pkg.tar.xz
Magic words:
psql -U postgres
Some interesting flags (to see all, use -h
or --help
depending on your psql version):
-E
: will describe the underlaying queries of the \
commands (cool for learning!)-l
: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)<?php | |

Convert LF endings into CRLF when you check out code.
core.autocrlf=true
Convert CRLF to LF on commit but not the other way around.
