構築方法

以下のVagrantfileで、Jupyter LabとMariaDBをインストールした仮想マシン(CentOS7.4)を構築できます。

Vagrantfile

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "bento/centos-7.4"
  config.vm.hostname = "co74jupyterlabmariadb"
  config.vm.provider :virtualbox do |vbox|
     vbox.name = "co74jupyterlabmariadb"
     vbox.cpus = 2
     vbox.memory = 2048
     vbox.customize ["modifyvm", :id, "--nicpromisc2","allow-all"]
  end

○動作確認用コード

import MySQLdb

con = MySQLdb.connect(
  user='test',
  passwd='test',
  host='localhost',
  db='test')

try:
  cur= con.cursor()
  sql = "select message_id, message from messages"
  cur.execute(sql)

  for row in cur.fetchall():
    print(row)

except MySQLdb.Error as er:
    print('MySQLdb.Error:', er)
cur.close
con.close
