Instalace na Windows 7

VirtualBox instaluji, protože nechci použít Hyper-v.

nainstalovat Oracle VM VirtualBox - http://www.oracle.com/technetwork/server-storage/virtualbox/overview/index.html
nainstalovat Vagrant - https://www.vagrantup.com/downloads.html

Oracle VM VirtualBox version: 5.0.20
Vagrant version: 1.8.1

První spuštění

# vagrant init hashicorp/precise32
# vagrant up

Na Windows 7 to vypadá následovně.

PS C:\HashiCorp\Vagrant\test> vagrant init hashicorp/precise32
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

Vlastní Vagrant Box

Lze najít desítky důvodů, proč si vytvořit vlastní Vagrant Box. Pro mě je to specifické nastavení a SW pro projekty v JAVA EE.

Následující návod popisuje vytvoření základního Vagrant Boxu:

distribuce GNU/Linux CentOS 7.0 x64 minimal

1. Download CentOS

Stáhnout CentOS 7.0 Minimal iso obraz.

Homepage: http://www.centos.org/download/
ČVUT mirror: http://ftp.cvut.cz/centos/7/isos/x86_64/
Obraz: CentOS-7.0-1406-x86_64-Minimal.iso

2. Run and config VirtualBox

Vytvořit virtuální server s následujícím nastavením:

Name: CentOS-7-minimal
Type: Linux
Version: Red Hat (64bit)
Memory size: 1 GB
Hard drive file type: VMDK (Virtual Machine Disk)
Hard drive size: 40 GB

V nastavení vytvořeného vyrtuálního serveru (Settings):

Audio: disable
USB: disable
Network
- Adapter 1: Nat, Advanced: Port Forwarding
- Port Forwarding Rules
  - Name: SSH
  - Protocol: TCP
  - Host IP: -
  - Host Port: 2222
  - Guest IP: -
  - Guest Port: 22

3. Install CentOS

Základní instalace CentOS do virtuálního stroje. Nastavit si lokalizaci a automatickou detekci sítě, jinak je možné vše ponechat ve výchozím stavu.

4. Settings CentOS

Změnit heslo správce systému root na vagrant.

# passwd

Přidat uživatele vagrant s heslem vagrant.

# adduser vagrant
# passwd vagrant

Nastavit pro uživatele vagrant sudo pro vše.

# visudo

Vložit řádek.

vagrant ALL=(ALL) NOPASSWD: ALL

Zakomentovat řádek.

#Defaults requiretty

Vyzkoušíme si dostupnost sítě.

# ping cesnet.cz

Provedeme aktualizaci systému.

# yum update

Nainstalovat Guest Tools

Vybrat v menu Devices → Insert Guest Additions CD image …

# yum groupinstall "Development Tools"
# yum install kernel-devel kernel-devel-3.10.0-123.el7.x86_64 wget
# mkdir /media/cdrom
# mount /dev/cdrom /media/cdrom
# cd /media/cdrom
# ./VBoxLinuxAdditions.run
# cd; umount /media/cdrom
# yum clean all

Kontrola instalace Guest Tools

# lsmod | grep vbox

Nastavení SSH pro uživatele vagrant.

# mkdir /home/vagrant/.ssh
# wget --no-check-certificate https://raw.github.com/mitchellh/vagrant/master/keys/vagrant.pub -O /home/vagrant/.ssh/authorized_keys
# chmod 0700 /home/vagrant/.ssh
# chmod 0600 /home/vagrant/.ssh/authorized_keys
# chown -R vagrant:vagrant /home/vagrant/.ssh

Vypnout

# shutdown -h now

4. Sestavení Vagrant Boxu

base = název z Oracle VM VirtualBox
output = název boxu

vagrant package --base CentOS-7-minimal --output CentOS-7-minimal.box

$ vagrant package --base CentOS-7-minimal --output CentOS-7-minimal.box
==> CentOS-7-minimal: Exporting VM...
==> CentOS-7-minimal: Compressing package to: c:/install/vagrant-boxes/CentOS-7-minimal.box

5. Test

vagrant package --base CentOS-7-minimal --output CentOS-7-minimal.box
vagrant box add testbox C:\install\vagrant-boxes\CentOS-7-minimal.box
vagrant init testbox
vagrant up

Přihlášení přes SSH

Host: localhost
Port: 2222
Uživatel: root
Heslo: vagrant

Vagrant Boxes

Vagrant Boxy vycházející z vlastního Vagrant Boxu.

* CentOS 7.0 x64 minimal

Plan

CentOS 7.0 x64 JAVA EE
CentOS 7.0 x64 PosgtreSQL
CentOS 7.0 x64 Puppet

Ansible Vagrant Box

vagrant package --base CentOS-7-minimal --output ansible.box
vagrant box add app C:\install\vagrant-boxes\ansible.box
vagrant box add app /c/install/vagrant-boxes/ansible.box
vagrant init app
vagrant up

JAVA EE Vagrant Box

vagrant package --base CentOS-7-minimal --output javaee.box
vagrant box add app C:\install\vagrant-boxes\javaee.box
vagrant box add app /c/install/vagrant-boxes/javaee.box
vagrant init app
vagrant up
