使用PXE工具批量部署服务器

目录

（1） 安装CentOS 6.5操作系统
（2） 配置与管理PXE主机
（3） 使用PXE批量部署安装服务器

PXE节点规划

前期准备

使用VMware workstation虚拟机软件，采用最小化安装方式安装CentOS 6.5 操作系统，使用镜像CentOS-6.5-x86_64-bin.iso，此虚拟机作为PXE的母机系统，使用该机进行批量安装服务器系统的操作。

（1）安装CentOS 6.5操作系统
①、安装CentOS 6.5操作系统（此处略过）
②、配置PXE（CentOS 6.5）母机
配置IP地址

[root@centos ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

HWADDR=00:0C:29:19:25:65

TYPE=Ethernet

UUID=3cd9fde2-0152-4772-abb5-637fcf1fb61d

ONBOOT=yes

NM_CONTROLLED=yes

BOOTPROTO=static

IPADDR=192.168.200.10

NETMSK=255.255.255.0

GATEWAY=192.168.200.1

重启网络服务

[root@centos ~]# service network restart

使用Winscp等远程传输文件软件来连接PXE母机，将CentOS-6.5-x86_64-bin.iso、CentOS-7.2-x86_64-DVD-1511.iso以及PXE.sh上传至PXE母机/root目录下

[root@centos ~]# ll

total 8734000

-rw-r–r--. 1 root root 29 May 1 01:20 abc

-rw-------. 1 root root 921 Apr 11 23:28 anaconda-ks.cfg

-rw-r–r--. 1 root root 4471971840 Jun 15 08:14 CentOS-6.5-x86_64-bin.iso

-rw-r–r--. 1 root root 4329570304 Jun 15 08:16 CentOS-7-x86_64-DVD-1511.iso

-rw-r–r--. 1 root root 8547467 May 12 01:20 etc.tar.gz

-rw-r–r--. 1 root root 9072 Apr 11 23:28 install.log

-rw-r–r--. 1 root root 3161 Apr 11 23:27 install.log.syslog

-rw-r–r--. 1 root root 22027 Jun 15 08:16 PXE.sh

drwxr-xr-x. 2 root root 4096 May 12 04:39 sh

-rw-r–r--. 1 root root 102400000 May 1 05:16 testfile

赋予PXE.sh可执行权限

[root@centos ~]# chmod +x PXE.sh

临时关闭selinux安全组，使用getenforce命令查看

[root@centos ~]# setenforce 0

[root@centos ~]# getenforce

Permissive

（2）配置与管理PXE主机

执行PXE母机安装脚本，选择“1”按”Enter”键安装PXE，命令如下

[root@centos ~]# ./PXE.sh

-------Install Info------------

1: install pxe

2: switch controller mode

3: switch compute mode

4: switch all mode

Please select installation services: (eg :1 / 2 / 3 )

至此，PXE母机安装完成！

（3）批量安装操作系统

①、安装环境配置说明
所需要安装系统的主机或服务器要与母机在同一网络下。默认主机或服务器为双网卡

注意事项：

主机或服务器开机后按F12键进入PXE网卡启动，选择系统安装，默认为“Install CentOS 7 CONTROLLER”，如图所示。

**至此，系统安装完成！

重启登录成功！**
