VagrantでApache Nifi 1.6.0とMariaDBがインストールされた仮想マシン(Debian Stretch/9.4)を構築する。

Apache Nifiは様々なデータを処理・分配するためのソフトウェアです。

〇Apache Nifiの画面

〇構築方法
1.以下のVagrantfileを使用して、Apache Nifi 1.6.0とMariaDBがインストールされた仮想マシン(Debian Stretch/9.4)を構築します。

Vagrantfile

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "bento/debian-9.4"
  config.vm.hostname = "db94nifi160mariadb"
  config.vm.provider :virtualbox do |vbox|
     vbox.name = "db94nifi160mariadb"
     vbox.cpus = 2
     vbox.memory = 2048
     vbox.customize ["modifyvm", :id, "--nicpromisc2","allow-all"]
  end
config.vm.network "private_network", ip: "192.168.55.104", :netmask => "255.255.255.0"
config.vm.network "public_network", ip:"192.168.1.104", :netmask => "255.255.255.0"
  config.vm.provision "shell", inline: <<-SHELL

2.DBCPConnectionPoolで、以下のようにパラメータを設定してローカルのMariaDBにアクセスします。
Database Connection -> URL jdbc:mysql://localhost/test
Database Driver Class Name -> com.mysql.jdbc.Driver
Database Driver Location(s) -> /usr/share/java/mysql-connector-java-8.0.11.jar
Database Userr -> test
Password -> test
