To setup your computer to work with *.dev domains, e.g. project.dev, awesome.dev and so on, without having to add to your hosts file each time.

目前 kubernetes 还没有提供“随机端口”的特性，所以实现起来比较麻烦。

下面前 2 种方案主要考虑的场景是 dubbo 运行在 kubernetes 集群中，但是也希望 kubernetes 集群“外”的应用也能使用这些 dubbo 服务。

实现原理：

dubbo 已经提供了 2 个环境变量： DUBBO_IP_TO_REGISTRY、DUBBO_PORT_TO_REGISTRY 分别表示服务注册到注册中心的 IP 和 PORT。

ps -ef | grep httpd | wc -l

netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}'

	## TODO:
	# Figure out how to get nginx file-aio module working (incompatible?)

	## Get and install tools and dependencies
	sudo apt-get -y install build-essential zlib1g-dev libpcre3 libpcre3-dev libbz2-dev

	## Get installed OpenSSL version
	# Use `whereis openssl` to check if installed first

	#!/bin/bash
	# bash generate random alphanumeric string

	# bash generate random 32 character alphanumeric string (upper and lowercase) and
	NEW_UUID=$(cat /dev/urandom \| tr -dc 'a-zA-Z0-9' \| fold -w 32 \| head -n 1)

	# bash generate random 32 character alphanumeric string (lowercase only)
	cat /dev/urandom \| tr -dc 'a-zA-Z0-9' \| fold -w 32 \| head -n 1
