LXC安装和配置（源码安装）

LXC安装和配置（源码安装）

测试环境：

（1）OS：UbuntuServer 13.10 amd64

（2）LXC1.0.0alpha1 源码

1. 配置Host网络

# nano /etc/network/interface

auto lo

iface lo inet loopback

# The primary network interface

#auto eth0

#iface eth0 inet dhcp

auto br0

iface br0 inet static

address 192.168.255.155

netmask 255.255.255.0

gateway 192.168.255.254

dns-nameservers 8.8.8.8 8.8.4.4

bridge_ports eth0

bridge_fd 9

bridge_hello 2

bridge_maxage 12

bridge_stp off

2. 卸载Apparmor

# /etc/init.d/apparmor stop

# update-rc.d -f apparmor remove

# apt-get --purge remove apparmor apparmor-utils libapparmor-perl libapparmor1

3. 安装必要软件包

# sed -i 's/us.archive.ubuntu.com/mirrors.163.com/g'/etc/apt/sources.list

# apt-get update

# apt-get install bridge-utils vim build-essential pkg-config m4 libtool gitfakeroot debootstrap libcap2-dev docbook autoconf git wget cgroup-lite

# reboot

4. 安装LXC源码

# wget https://github.com/lxc/lxc/archive/lxc-1.0.0.rc2.tar.gz
# tar zxvf lxc-1.0.0.rc2.tar.gz

# cd lxc-1.0.0.rc2

# ./autogen.sh

# ./configure

# make

# make install

5. 安装路径

/usr/local/bin

/usr/local/etc/lxc/default.conf

/usr/local/lib/lxc/rootfs

/usr/local/share/lxc/config, hooks, templates

/usr/local/var/lib/lxc/{lxc_name}

6. 创建LXC（以Ubuntu最新发行版为模版）

# lxc-checkconfig

# lxc-create -n ubuntu -t ubuntu

7. 修改ubuntulxc instance网络配置

# nano /usr/local/var/lib/lxc/ubuntu

# 隔离同一宿主机上不同虚拟机之间的通讯（很关键的安全防护，所有虚拟机流量全部到ToR，再返回）

lxc.network.type = macvlan

lxc.network.macvlan.mode = vepa

lxc.network.flags = up

lxc.network.link = br0

# 支持LXC嵌套

lxc.hook.mount = /usr/local/share/lxc/hooks/mountcgroups

8. 启动ubuntulxc instance

# lxc-start -n ubuntu

 

附录，LXC网络模型：

（1）虚拟机与宿主机无法通信

lxc.network.type = macvlan

lxc.network.macvlan.mode = bridge

（2）虚拟机间无法通信

lxc.network.type = macvlan

lxc.network.macvlan.mode = vepa

（3）虚拟机没有网络

lxc.network.type = empty
