# 使用LXD创建管理基于容器的虚拟机
|
||
|
||
## 机器环境
|
||
|
||
- Ubuntu 18.04 LTS
|
||
|
||
## 安装LXD
|
||
|
||
- 分别安装LXD， ZFS和bridge-utils
|
||
- LXD 实现虚拟容器
|
||
- ZFS 用于管理物理磁盘，支持LXD高级功能
|
||
- bridge-utils 用于搭建网桥
|
||
|
||
```
|
||
sudo apt-get install lxd zfsutils-linux bridge-utils
|
||
```
|
||
|
||
## 配置网桥
|
||
- /etc/netplan/01-network-manager-all.yaml（文件名根据自己的来）
|
||
|
||
```
|
||
# Let NetworkManager manage all devices on this system
|
||
network:
|
||
version: 2
|
||
# renderer: NetworkManager
|
||
ethernets:
|
||
ens33:
|
||
dhcp4: true
|
||
bridges:
|
||
ldxbr0:
|
||
interfaces: [ens33]
|
||
dhcp4: true
|
||
```
|
||
|
||
- sudo netplan apply (使配置生效)
|
||
|
||
## 初始化LXD
|
||
|
||
- sudo lxd init
|
||
|
||
```
|
||
ubuntu@ubuntu-lxd-tut:~$ sudo lxd init
|
||
Name of the storage backend to use (dir or zfs): zfs
|
||
Create a new ZFS pool (yes/no)? yes
|
||
Name of the new ZFS pool: lxd
|
||
Would you like to use an existing block device (yes/no)? yes
|
||
Path to the existing block device: /dev/sdb1
|
||
Would you like LXD to be available over the network (yes/no)? no
|
||
Do you want to configure the LXD bridge (yes/no)? no
|
||
Warning: Stopping lxd.service, but it can still be activated by:
|
||
lxd.socket
|
||
LXD has been successfully configured.
|
||
```
|
||
|
||
- lxc network attach-profile ldxbr0 default eth0 （ 意思是默认ldxbr0作为新建容器的eth0网卡）
|
||
|
||
## 配置LXC镜像源（加速创建）
|
||
|
||
```
|
||
lxc remote add tuna-images https://mirrors.tuna.tsinghua.edu.cn/lxc-images/ --protocol=simplestreams --public
|
||
lxc image list tuna-images:
|
||
```
|
||
|
||
## 启动容器虚拟机
|
||
|
||
```
|
||
lxc launch tuna-images:centos/7/amd64 centos-vm1
|
||
# 这里启动了一台名字叫centos-vm1的容器虚拟机
|
||
```
|
||
|
||
## 进入容器虚拟机
|
||
|
||
```
|
||
lxc exec centos-vm1 bash
|
||
```
|
||
|
||
## 安装LXD的WebUI
|
||
|
||
- git clone https://github.com/AdaptiveScale/lxdui.git
|
||
- cd lxdui
|
||
- python3 setup.py install
|
||
- lxdui start
|
||
- http://server_ip:15151
|
