〇構築方法
1.以下のVagrantfileを使用して、Apache Nifi 1.6.0とPercona Server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 = "db94nifi160pg"
config.vm.provider :virtualbox do |vbox|
vbox.name = "db94nifi160pg"
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

end
2.DBCPConnectionPoolで、以下のようにパラメータを設定してローカルのPostgreSQLにアクセスします。
Database Connection URL -> jdbc:postgresql://localhost:5432/test
Database Driver Class Name -> org.postgresql.Driver
Database Driver Location(s) -> /opt/jdbc/postgresql-42.2.2.jar
Database User -> test
Password -> test
