今更かもしれないけれども Vagrant を触ったので備忘録としてメモ

前提情報

母艦OS macOS Mojave

バージョン情報

CentOS 7.6-1810
VirtualBox 6.0.6
vagrant 2.2.4

マスタにするVM名（テキトー）

centos76master

マスタにするOSのインストール時の作業

OSインストール時に作成するユーザ一覧

root: vagrant
vagrant: vagrant

設定するNAT用interface（よしなに）

enp0s3: 10.0.2.15/24

マスタにするOSインストール後の作業

ファイルバックアップ用ディレクトリの作成

# mkdir /root/backup

OS最新化およびwgetとbzip2のインストール

# yum update
# yum install wget
# yum install bzip2

yum repositoryの設定

EPEL

# yum install epel-release

Remi

# wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# wget https://rpms.remirepo.net/enterprise/remi-release-7.rpm
# rpm -Uvh remi-release-7.rpm epel-release-latest-7.noarch.rpm

sshの設定

# su - vagrant
$ mkdir .ssh
$ chmod 700 .ssh
$ cd .ssh 
$ curl -k -L -o authorized_keys 'https://raw.github.com/mitchellh/vagrant/master/keys/vagrant.pub'
$ chmod 600 authorized_keys
$ ..
$ chown -R vagrant.vagrant .ssh
$ exit

sudoの設定

# cp /etc/sudoers ./backup/sudoers.old
# visudo
# cp /etc/sudoers ./backup/sudoers.new
# diff .//backup/sudoers ./backup/sudoers.new 
110a111
> vagrant	ALL=(ALL)	NOPASSWD: ALL

vagrant用の追加パッケージのインストール

# yum install kernel kernel-devel perl gcc

selinuxの無効化（許して・・・）

# cp /etc/selinux/config ./backup/selinux_config.old
# vi /etc/selinux/config 
# cp /etc/selinux/config ./backup/selinux_config.new
# diff ./backup/selinux_config.old ./backup/selinux_config.new
7c7
< SELINUX=enforcing
---
> SELINUX=disabled

firewalldの停止と無効化（許して・・・）

# systemctl stop firewalld
# systemctl disable firewalld

virtualbox guest additionalsのインストール

# wget https://download.virtualbox.org/virtualbox/6.0.6/VBoxGuestAdditions_6.0.6.iso
# mount -t iso9660 VBoxGuestAdditions_6.0.6.iso /mnt
# /mnt/VBoxLinuxAdditions.run

おそらく以下のエラーが出力されるはず・・・

# sh /mnt/VBoxLinuxAdditions.run 
Verifying archive integrity... All good.
Uncompressing VirtualBox 6.0.6 Guest Additions for Linux........

The log file /var/log/vboxadd-setup.log may contain further information.

エラーの対処（のはず・・・）

# yum -y install kernel-3.10.0-957.10.1.el7
# yum -y install kernel-headers-3.10.0-957.10.1.el7
# yum -y install kernel-devel-3.10.0-957.10.1.el7
# reboot
# /sbin/rcvboxadd setup
# /sbin/rcvboxadd quicksetup all

マスタ用の最適化

余計なファイルの削除等実施

# yum clean all
# dd if=/dev/zero of=/EMPTY bs=1M
# rm -f /EMPTY
# shutdown -h now

母艦(macOS)での作業

$ cd /Users/sfukumura/Downloads/working
$ vagrant package --base centos76master
$ vagrant box add --name centos76minimal package.box
$ vagrant box list
$ vagrant init centos76minimal
$ vi Vagrantfile
$ vagrant up
$ vagrant ssh

vagrant up時に以下のエラーが出るかも

Vagrant was unable to mount VirtualBox shared folders. This is usually
because the filesystem "vboxsf" is not available. This filesystem is
made available via the VirtualBox Guest Additions and kernel module.
Please verify that these guest additions are properly installed in the
guest. This is not a bug in Vagrant and is usually caused by a faulty
Vagrant box. For context, the command attempted was:

mount -t vboxsf -o uid=1001,gid=1001 vagrant /vagrant

The error output from the command was:

/sbin/mount.vboxsf: mounting failed with the error: No such device

エラーの対処（のはず・・・）

$ vagrant plugin install vagrant-vbguest
