vagrant(5)基于centos7镜像优化

Posted on Views:

目的

开启密码、key认证、添加国内yum源、增加磁盘大小、关闭selinux、安装常用软件包、关闭防火墙

1.Vagrantfile

Vagrant.configure("2") do |config|
    config.vm.box = "centos7"
    config.vm.hostname = "vgt-c7-101"
    config.disksize.size = '50GB'
    #config.vm.disk :disk, size: "50GB", primary: true
    config.vm.network "private_network", ip: "172.24.20.101", hostname: true
    config.ssh.insert_key = true
    config.vm.provider "virtualbox" do |vb|
      vb.memory = 2048
      vb.cpus   = 2
      vb.name   = "vgt-c7-101"
    end

    config.vm.provision "shell", path: "init.sh"
end

注意：依赖 vagrant-disksize
vagrant plugin install vagrant-disksize
