CentOS7环境下的PXE-kickstart全自动网络部署（静态IP）

4-28 14 views

一、环境准备

1.1 镜像

准备工作，如果没有可以去“http://ftp.sjtu.edu.cn/centos”下载
CentOS的历史版可以到“http://vault.centos.org/”下载

CentOS 7 安装镜像
CentOS 6 安装镜像

1 2	CentOS 7 安装镜像 CentOS 6 安装镜像

1.2 PXE环境

单台也可以哈，不强制必须要2台

文件服务器 192.168.99.2
PXE服务器 192.168.99.1

1 2	文件服务器 192.168.99.2 PXE服务器 192.168.99.1

二、部署环境

2.1 文件服务器

2.1.1 关闭防火墙

[root@localhost ~]# systemctl disable firewalld
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# sed -i '/SELINUX/s/enforcing/disabled/g' /etc/selinux/config
[root@localhost ~]# reboot

[root@localhost ~]# systemctl disable firewalld

[root@localhost ~]# systemctl stop firewalld

[root@localhost ~]# sed -i '/SELINUX/s/enforcing/disabled/g' /etc/selinux/config

[root@localhost ~]# reboot

2.1.2 安装并配置中间件

[root@localhost ~]# yum install httpd system-config-kickstart -y
[root@localhost ~]# systemctl enable httpd
[root@localhost ~]# systemctl start httpd

[root@localhost ~]# yum install httpd system-config-kickstart -y

[root@localhost ~]# systemctl enable httpd

[root@localhost ~]# systemctl start httpd

2.1.2 配置”文件服务器”

操作前先将两个镜像挂载到服务器中，此处我是分别挂载到“/mnt”和“/media”下

[root@localhost ~]# mkdir -p /var/www/html/centos/7 ; cp -r /mnt /var/www/html/centos/7/os
[root@localhost ~]# cp -r /media /www/html/centos/6/os

1 2	[root@localhost ~]# mkdir -p /var/www/html/centos/7 ; cp -r /mnt /var/www/html/centos/7/os [root@localhost ~]# cp -r /media /www/html/centos/6/os

2.1.3 ks脚本

CentOS 6

三、开始自动安装

将要安装的系统接入到跟PXE同一网段，然后从网络启动就好
