L2TP/IPsec(AndroidやiPhoneからのVPN接続)を経路を用意すべくVPSにL2TP/IPsecサーバを設置するとき、ネットにある情報だとなかなかつながらないから、標準環境としてAWSのCentOS 6.3 x86_64 Release Media(ami-3fe8603e)の起動直後から最短距離で設定する方法をまとめた。

CentOS 6でとにかくL2TP/IPsecサーバ

  • AWSでEC2のインスタンスを借りる
  • 今回は東京リージョンのCentOS 6.3 x86_64 Release MediaのAIM(ami-3fe8603e)でインスタンスを建てる
  • Security Group: L2TP/IPsec(Inbound 22/TCP: SSH, 500/UDP: ISAKMP, 1701/UDP: L2TP, 4500/UDP: IPSec NAT Traversal)を許可
  • ec2-54-249-173-214.ap-northeast-1.compute.amazonaws.com(グローバルIPアドレス:54.249.173.214)にrootでログイン

Benchmarking Nginx with Go

Benchmarking Nginx with Go

There are a lot of ways to serve a Go HTTP application. The best choices depend on each use case. Currently nginx looks to be the standard web server for every new project even though there are other great web servers as well. However, how much is the overhead of serving a Go application behind an nginx server? Do we need some nginx features (vhosts, load balancing, cache, etc) or can you serve directly from Go? If you need nginx, what is the fastest connection mechanism? This are the kind of questions I'm intended to answer here. The purpose of this benchmark is not to tell that Go is faster or slower than nginx. That would be stupid.

So, these are the different settings we are going to compare:

  • Go HTTP standalone (as the control group)
  • Nginx proxy to Go HTTP
  • Nginx fastcgi to Go TCP FastCGI
  • Nginx fastcgi to Go Unix Socket FastCGI
