Vagrant virtual machine installation, disk expansion and LAN access tutorial

1. download vagrant as well as virtualBox

  Deserve to go up vagrant,virtualBox Online download address ：
  vagrant Download address
  virtualBox Download address

2. Start preparing to install the image file

Find the system image file that needs to be installed , Deserve to go up vagrant Mirror address ：vagrant Mirror address

   $ vagrant init {title} # You need to create a separate directory to init operation , And you need to enter the current directory every time you start 
   $ vagrant up

After starting , open virtualBox, You can see the following picture scene ：

The above is the virtual machine configuration and startup of the default parameters , Through

$ vagrant ssh

You can connect to the virtual machine .

3. To begin vagrant Expansion of the original partition and other machines in the LAN ssh Tool connection

1）vagrant Expansion of the original partition

In execution vagrant init , In the directory, a file named "Vagrantfile" The file of , After opening, configure the following parameters

Vagrant.configure("2") do |config|
  config.vm.box = "envimation/ubuntu-xenial"
  config.disksize.size = "30GB"
end

Good configuration , In execution $ vagrant up, Will prompt

Vagrant:
* Unknown configuration section 'disksize'.

Solution , perform

$ vagrant plugin install vagrant-disksize

Wait for about 1 Minutes later , It will prompt that the installation is successful . At the moment , You can execute $ vagrant up.

After the virtual machine starts , After connecting the virtual machine , Input

$ df -h

You can see the following parameters

  however , Before partition expansion , What you see should be the default 9.7G The capacity of .

At this moment, enter the following command to view the partition capacity ：

$ fdisk /dev/sda

Enter... After the command line :p, Print area , as follows

You can see , Actually /dev/sda Has become a 30G 了 , But what you see /dev/sda1 Maybe it's just 9.3G, Don't panic at the moment , You can operate the expansion smoothly according to the following commands .

stay Commant Type in ：d

Delete useless partitions , After deleting , In the input n, To create partitions .

When creating partitions , Create partition 1, Because the default partition is the partition 1, And then input w, Preservation .

If you are prompted when saving

Re-reading the partition table failed.: Device or resource busy

It may be that this partition is currently in use , Don't panic , Enter the following command

$ partprobe /dev/sda
$ e2fsck /dev/sda1
$ resize2fs /dev/sda1

Now you can see that the expansion is successful .

4. Other machines in the LAN use ssh Tools to access

open Vagrantfile file , Configure the following parameters

Vagrant.configure("2") do |config|
  config.vm.box = "envimation/ubuntu-xenial"
  config.disksize.size = "30GB"
  config.vm.network "public_network", ip: "192.168.1.2"
end

ip Address configuration , The first three digits are required to follow this computer ip The first three are consistent , The latter bit is randomly configured . Good configuration , restart vagrant That's it .
