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.gz
tar zxvf xen-shell-1.9.tar.gz cd xen-shell make make install
1.建立连接VPS的用户与密码
useradd eric passwd eric useradd yangzi passwd yangzi
2.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 yangzi
3.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/eric
5.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
