本文主要记录自己在西部数码 VPS 安装 ubuntu 的过程
添加 root 用户
#adduser user 这个命令可以创建 Home 目录和 Shell 路径，useradd 则不会自动创建 Home 目录
Ubuntu 重启不能进入 VPS
原因：查看 /boot/grub/grub.cfg
if [ "${recordfail}" = 1 ]; then
set timeout=-1
else
set timeout=2正是被这个-1 给停留到启动界面的
解决办法： 先将/boot/grub/grub.cfg 默认只读修改为可写入 cd /boot/grub chmod 644 grub.cfg 修改成 root 用户可写
然后 vi /boot/grub/grub.cfg 找到 timeout
if [ "${recordfail}" = 1 ]; then
set timeout=-1 改为 0国内镜像
以 Precise(12.04)为例, 编辑/etc/apt/sources.list 文件, 在文件最前面添加以下条目(操作前请做好相应备份)
