Casual test by ab program through ngrok tunnel

  • ngrokが気になっていたので、以下のような構成でテストをやってみた
  • wifiルータは0001softbank

f:id:nishidy:20150421212754p:plain

  • haproxyで設定した通りにL4-NAT負荷分散されていることを、VM内でphp/sqlite3で簡素なカウンターを実装して目視で確認
  • nginxはsupermarket.chef.ioのBerkshelvesからcookbookを落としてchef-soloで入れてみた
  • ちなみにvagrant shareでもngrokと同じようにvagrantゲストに対してトンネルが張れるが、今回はhaproxyをホストで動かしている
Vagrant.configure(2) do |config|
  config.omnibus.chef_version = :latest
  config.berkshelf.enabled = false

  config.vm.box = "centos65"

  config.vm.network "forwarded_port", guest: 80, host: 10011

  config.vm.provider "virtualbox" do |vb|
    vb.memory = "512"
  end

  config.vm.provision "shell", inline: <<-SHELL
    sudo yum install -y vim php php-fpm php-pdo sqlite
  SHELL

  config.vm.provision :chef_solo do |chef|
    chef.cookbooks_path = ["./berks-cookbooks"]
    chef.add_recipe "nginx"
  end
end
  • haproxyコンフィグ(今回のabテストではbackend web1のみを使用)
  • httpchkでもカウンタをふむとカウントされてしまうので、index.htmlをhttpchkに使い、index.phpをデフォルトindexとしてこちらにカウンタを設置
global
  maxconn 4096
  pidfile tmp/haproxy-queue.pid
