VagrantでsysbenchとPostgreSQL10をインストールした仮想マシン(CentOS7.5)を構築する

sysbenchでホストマシンやデータベースのベンチマークを行うことができます。

〇構築方法
以下のVagrantfileを使用して、sysbenchとPostgreSQL10がインストールされた仮想マシン(CentOS7.5)を構築します。

Vagrantfile

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "bento/centos-7.5"
  config.vm.hostname = "co75sysbenchmariadb"
  config.vm.provider :virtualbox do |vbox|
     vbox.name = "co75sysbenchmariadb"
     vbox.cpus = 2
     vbox.memory = 2048
     vbox.customize ["modifyvm", :id, "--nicpromisc2","allow-all"]
  end
  # private network
config.vm.network "private_network", ip: "192.168.55.65", :netmask => "255.255.255.0"
  # bridge netwrok
config.vm.network "public_network", ip: "192.168.1.65", :netmask => "255.255.255.0"
  config.vm.provision "shell", inline: <<-SHELL
