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
