使用xen-shell来管理xen vps
XEN 的强大管理工具 XEN-SHELL，用他来管理XEN的虚拟机，简直是太方便了。太强大了，支持系统重装，VPS 启动、重启、关机、暂停，连接控制台。
wget http://xen-tools.org/software/xen-shell/xen-shell-1.9.tar.gztar zxvf xen-shell-1.9.tar.gz
cd xen-shell
make
make install1.建立连接VPS的用户与密码
useradd eric
passwd eric
useradd yangzi
passwd yangzi2.给用户 sudo 的命令权限,和登录shell
vim /etc/sudoers
#加入以下
User_Alias XENUSERS = eric,yangzi
Cmnd_Alias XEN = /usr/sbin/xm
Cmnd_Alias XENIMG = /usr/bin/xen-create-image
XENUSERS ALL = NOPASSWD: XEN,XENIMG# 执行下列命令，让用户登录到 xen-shell
chsh -s /usr/local/bin/xen-login-shell eric
chsh -s /usr/local/bin/xen-login-shell yangzi3.修改xen 虚拟机的配置文件，加入
xen_shell = "eric"例如：
kernel = "/boot/vmlinuz-2.6.24-28-xen"
ramdisk = "/boot/initrd.img-2.6.24-28-xen"
memory = "64"
name = "xenyang"
xen_shell = "eric"
disk = ['phy:/dev/md0,sda1,w']
root = "/dev/sda1 ro"
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
vcpus = '2'
extra = 'xencons=tty1'
vif = [ '' ]4.(可选)如果你需要用xen-shell 来重装系统的话,就做这步
在eric 的home 目录下新建image.sh
cd /home/eric
vim image.sh
#!/bin/sh
/usr/bin/sudo /usr/bin/xen-create-image --hostname=yang \
--size=1.5Gb \
--ide \
--ip=192.168.6.36 \
--netmask=255.255.255.0 \
--gateway=192.168.6.1 \
--force \
--kernel=/boot/vmlinuz-2.6.24-28-xen \
--dist=hardy \
--mirror=http://mirrors.163.com/Ubuntu/ \
--arch=i386 \
--passwd \
--dir=/home/eric5.使用xen-shell 来控制 vps
打开putty 填入 xen 服务器IP地址 输入新建的用户名 eric
