LXC - Linux Containers
2014-01-11
- <參考> Creating a virtualized fully-distributed Hadoop cluster using Linux Containers
- 測試環境：Debian Wheezy 7.1 netinstall ISO with preseed
jazz@debian:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 7.3 (wheezy)
Release: 7.3
Codename: wheezy
- 安裝 LXC
jazz@debian:~$ sudo apt-get install lxc
- 產生虛擬機器
jazz@debian:~$ sudo lxc-create -t debian -n test1
jazz@debian:~$ sudo lxc-start -d -n test1
- 安裝 LXC Web Panel
root@debian:~# wget http://lxc-webpanel.github.io/tools/install.sh -O - | bash
- <狀況> 指令可以建立 LXC VM, 但網頁似乎不太靈光。
2014-01-12
- 測試環境：Ubuntu 12.04 LTS
jazz@jazzbook:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04.2 LTS
Release: 12.04
Codename: precise
- 感覺上 LXC 1.0 的功能比較齊全(Ex. 支援根據 DNS 分配 IP 的機制)，因此直接採用 precise-backports 套件庫中的 lxc 1.0 版本
echo "deb http://free.nchc.org.tw/ubuntu precise-backports main universe" > /tmp/precise-backport.list
sudo mv /tmp/precise-backport.list /etc/apt/sources.list.d/
sudo apt-get update
- 安裝 LXC 1.0 版本
sudo apt-get install lxc
jazz@jazzbook:~$ lxc-version
lxc version: 1.0.0.alpha1
- 安裝 LXC Web Panel
jazz@jazzbook:~$ sudo su -
root@jazzbook:~# wget http://lxc-webpanel.github.io/tools/install.sh -O - | bash
- 建立 20 個 VM 名稱對應
- 根據 /etc/default/lxc-net 的說明，可以設定一個檔案，來根據 hostname 決定 IP 分配
# Uncomment the next line if you'd like to use a conf-file for the lxcbr0
# dnsmasq. For instance, you can use 'dhcp-host=mail1,10.0.3.100' to have
# container 'mail1' always get ip address 10.0.3.100.
#LXC_DHCP_CONFILE=/etc/lxc/dnsmasq.conf
