Introduction

Chinese Version:[ Linux VPS ] CentOS 网络安装/重装系统一键脚本纯净安装

Suitable for use by GRUB boot CentOS, Ubuntu, Debian system.
Use the official distribution to remove the template preinstalled software.
At the same time, it can also solve the problem of kernel version and software incompatibility.
As long as you have root privileges, you also have a pure system.

Installation

Notice

Fully install the default root password: Vicer, change the password immediately after installation.
The VNC function is provided by default during fully automatic installation. You can use the VNC Viewer to check the progress.
The VNC port is 1 or 5901 and can be connected by itself. (The VNC function will disappear after successful.)
Currently only supports CentOS 6.9 and below (5.x, 6.x).
Importance: The OpenVZ framework does not apply.

Update

[2018.03.30]
Optimize GRUB detection logic.
Add component dependency detection.
Fix the problem of multiple network cards.
Fix some known bugs.

Requirement

Debian/Ubuntu/CentOS system (Guided by GRUB);
Wget is used to download files and obtain public IP addresses.
Ip get gateway, mask, etc.
Sed awk grep handles text streams;
Openssl creates the root user password;
Xz-utils repackages the image.

Make sure the required software is installed:

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

If something goes wrong, run:

#Debian/Ubuntu:
apt-get update
 
#RedHat/CentOS:
yum update

One-click download and use:

wget --no-check-certificate -qO CentOSNET.sh 'https://moeclub.org/attachment/LinuxShell/CentOSNET.sh' && chmod a+x CentOSNET.sh

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

# Automatically install using the default image
bash CentOSNET.sh -c 6.8 -v 64 -a

# Automatically install using custom image
bash CentOSNET.sh -c 6.9 -v 64 -a --mirror 'http://mirror.centos.org/centos'

# Use Custom Mirroring to Customize Network Parameters Automatic Installation
#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'

Tips:

If you see “Starting graphical installation” or a similar expression, you are installing.
Under normal circumstances only need to wait patiently to complete the installation.
If you need to check the progress, use VNC Viewer (or other VNC connection tool)
The IP address in the connection prompt: The port is connected. (The port is usually 1 or 5901)
