适用于由GRUB引导的CentOS,Ubuntu,Debian系统.
使用官方发行版去掉模板预装的软件.
同时也可以解决内核版本与软件不兼容的问题。
只要有root权限,还您一个纯净的系统。
[ Linux VPS ] Debian(Ubuntu)网络安装/重装系统一键脚本
-
- 注意:
- 全自动安装默认root密码:
Vicer
,安装完成后请立即更改密码.
- 全自动安装时默认提供VNC功能,可使用VNC Viewer查看进度,
VNC端口为1或者5901,可自行尝试连接.(成功后VNC功能会消失.)
- 目前只支持 CentOS 6.9 及以下版本(5.x,6.x).
特别注意:OpenVZ
构架不适用.
1.Debian/Ubuntu/CentOS
系统(由GRUB
引导);
2.wget
用来下载文件,获取公网IP;
3.ip
获取网关,掩码等;
4.sed awk grep
处理文本流;
5.openssl
创建root用户密码;
6.xz-utils
重新打包镜像.

#Debian/Ubuntu:
apt–get install –y xz–utils openssl gawk coreutils file
#RedHat/CentOS:
yum install –y xz openssl gawk coreutils file

Usage:
bash CentOSNET.sh –c/—centos [dist–version]
–v/—ver [32/i386|64/amd64]
—ip–addr/—ip–gate/—ip–mask
–yum/—mirror
–a/–m

#使用默认镜像全自动安装
bash CentOSNET.sh –c 6.8 –v 64 –a
#使用自定义镜像全自动安装
bash CentOSNET.sh –c 6.9 –v 64 –a —mirror ‘http://mirror.centos.org/centos’
#使用自定义镜像自定义网络参数全自动安装
#bash CentOSNET.sh -c 6.9 -v 64 -a –ip-addr x.x.x.x –ip-gate x.x.x.x –ip-mask x.x.x.x –mirror ‘http://mirror.centos.org/centos’

如果看到 “Starting graphical installation” 或者类似表达,则表示正在安装.
正常情况下只需要耐心等待安装完成即可.
如果需要查看进度,使用VNC Viewer(或者其他VNC连接工具)
连接提示中的IP地址:端口进行连接.(端口一般为1或者5901)
