创建RHELVagrantBox

TurnToJPG -->

背景

调研RHEL6.5, 为了在vagrant环境中验证我们的修改，故创建该系统的vagrant box

准备

Virtualbox 5.1.22 r115126, vagrant 1.9.1, CentOS 7.3(host机器)
创建一台虚拟机，配置如下:

内存: 512 m
网卡: NAT, port forward: 2223 -> 22
硬盘: 40 G
声卡: 禁用

用RHEL 6.5的ISO安装系统，安装完毕之后，将自动重启。

配置

激活网络，通过配置/etc/sysconfig/network-scripts/ifcfg-eth0, 设置为boot=yes.

安装完毕后，依然插入RHEL 6.5 ISO, 将其挂载到/mnt目录，并配置本地安装源:

# mount /dev/sr0 /mnt
# vim /etc/yum.repos.d/local.repo
[local]
name=local
baseurl=file:///mnt
enabled=1
gpgcheck=0
# yum makecache&&yum install -y vim kernel-devel gcc bzip2

添加vagrant用户:

# useradd -m vagrant
# passwd vagrant
# cp /root/.bashrc /home/vagrant/.bashrc
# chmod 777 /home/vagrant/.bashrc
# chown -R vagrant /home/vagrant/.bashrc

添加vagrant用户到visudo:

# visudo 
vagrant ALL=(ALL)	NOPASSWD:ALL
Defaults:vagrant	!requiretty

if you have make vagrant to be the member of %wheel, be sure to add nopassword for this group.

预置ssh-key:

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

配置ssh登录:

# vim /etc/ssh/sshd_config
AuthorizedKeysFile .ssh/authorized_keys

Edit your /etc/default/grub. Change the line from

GRUB_CMDLINE_LINUX=""
to
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
# grub-mkconfig -o /boot/grub/grub.cfg

Edit the network configuration:

# vim /etc/network/interfaces
auto eth0
iface eth0 inet dhcp
# chsh vagrant
/bin/bash
# cp /home/xxx/.bashrc /home/vagrant/.bashrc
# cp /home/xxx/.bash_logout /home/vagrant/.bash_logout
# cp /home/xxx/.profile /home/vagrant/.profile
# vim /home/vagrant/.profile
add
[ -z "$BASH_VERSION" ] && exec /bin/bash -l
# sudo chsh -s /bin/bash vagrant

VBoxAdditional iso

在虚拟机的界面上点击Device -> Install Guest Additional CD image， 而后:

# mount /dev/sr0 /mnt
# cd /mnt
# ./VBoxLinuxAdditions.run

压缩

使用dde命令清除空余空间:

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

形成rhel vagrant包:

# vagrant package --base rhelbox

测试

安装镜像文件:

# vagrant box add package.box --name "rhel65"
# vagrant init rhel65
# vagrant up

CentOS7

First you have to copy /etc/sysconfig/network-scripts/ifcfg-enp0sxxx to /etc/sysconfig/network-scripts/ifcfg-eth0, and edit its configuration by replacing enp0sx to eth0, then you have to edit the grub configuration for naming from enp0sx to eth0:

Edit your /etc/default/grub. Change the line from
GRUB_CMDLINE_LINUX=""
to
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

Finally you make the new configuration for grub2:

# grub2-mkconfig -o /boot/grub2/grub.cfg

if you have make vagrant to be the member of %wheel, be sure to add nopassword for this group.

Ignore VBoxAddons

Ignore synced_folder definition in Vagrantfile:

  config.vm.synced_folder "../data", "/vagrant_data",  disabled: true
  config.vm.synced_folder ".", "/vagrant", disabled: true

Update for rhel7

After changing the grub configuration, do following:

# grub2-mkconfig -o /boot/grub2/grub.cfg 

Change the networking via(old one to new one):

# cd /etc/sysconfig/network-scripts/
# mv ifcfg-xxxx ifcfg-eth0
