篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了RHCE之HTTPD+FTP+KickStart发布镜像,用于KVM的VM自动安装过程相关的知识,希望对你有一定的参考价值。
最近在学习RHCE课程,上一篇简单的讲一下如何用HTTP来作为KVM的VM网络安装过程,请阅读:http://gshao.blog.51cto.com/3512873/1882093
今天讲到FTP+HTTP+KickStart发布,当然还有PXE安装RHEL(后续讲)。
环境:
虚拟宿主机:RHEL 7.0
硬件:4vCPU+8G+40Gdisk
IP地址:172.16.38.10
vnet ip地址:192.168.100.1
先截图上一篇装完rhel系统的样子:
回归到正文,今天讲HTTPD+FTP+KickStart发布镜像。
1.先安装httpd服务,由于我们上一篇已安装,我们先确保httpd服务能正常启动,并测试web服务器的dvd目录是否正常访问;
[[email protected] ~]# systemctl status httpd #查看HTPPD服务状态
httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled)

Main PID: 14615 (httpd)

Dec 12 21:56:18 localhost.localdomain systemd[1]: Started The Apache HTTP Server.
Hint: Some lines were ellipsized, use -l to show in full.
别记错哦,这里是对外的ip地址,不是对内的vnet ip地址;
2.安装FTP服务;
[[email protected] ~]# yum install vsftpd -y #安装vsftpd服务
3.启动vsftpd服务,启用vsftpd服务,测试ftp是否可以正常访问;
[[email protected] ~]# systemctl start vsftpd #启动vsftpd服务 [[email protected] ~]# systemctl enable vsftpd #启用vsftpd服务
ln -s ‘/usr/lib/systemd/system/vsftpd.service‘ ‘/etc/systemd/system/multi-user.target.wants/vsftpd.service‘
[[email protected] ~]# systemctl status vsftpd
vsftpd.service - Vsftpd ftp daemon
Loaded: loaded (/usr/lib/systemd/system/vsftpd.service; enabled)
Active: active (running) since Tue 2016-12-13 19:41:51 CST; 21s ago

Dec 13 19:41:51 localhost.localdomain systemd[1]: Started Vsftpd ftp daemon.
4.安装KickStart服务;
[[email protected] ~]# yum install system-config-k #安装KickStart服务
5.启动Kickstart配置文件控制面板;
[[email protected] ~]# system-config-kickstart & #启动kickstart控制面板
6.在Kickstart Configurator-Basic Configuration界面,配置Time Zone时间为Asia/Shanghai,输入Root Passowrd,勾选Reboot system after installation和Perform installation in text mode(grahical is default);
7.在Kickstart Configurator-Installation Method,勾选Perform new installation,勾选HTTP,输入HTTP Server地址:192.168.100.1,HTTP Diretory为dvd/;
8.在Kickstart Configurator-Boot Loader Options,勾选install new boot loader,勾选Install boot loader on Master Boot Record(MBR);
9.在Kickstart Configurator-Partition Information,勾选Clear Master Boot Record,勾选Remove all existing partitions,勾选Initialize the disk label,Add swap和/分区,并分配空间;
10.在Kickstart Configurator-Network Configuration,点击Add Network Device,输入Network Device名,配置Network Type为DHCP;
11.在Kickstart Configurator-Firewall Configuration,配置SELinux为Warn,配置Security level为Disable firewall;
12.其他部分保持默认,如果你要添加shell,可以在Pre-Installation Script或者Post-Installation Script添加对应的shell脚本
13.点击File-Save;
14.因为我们之前搭建vsftp服务,我们直接存放在/var/ftp/pub里面;
15.补充一点,Package Selection默认在Kickstart配置器是不能勾选的;
16.我们可以通过在/root目录有个anaconda-ks.cfg,这个也是Kickstart配置文件,进行将Package Selection的部分内容复制到我们刚才制作的ks.cfg配置文件中;
[[email protected] ~]# ll #查看/root目录下的文件和目录信息

我们将这部分复制出来,张贴到ks.cfg配置文件;
[[email protected] ~]# vim /var/ftp/pub/ks.cfg #编辑ks.cfg配置文件
#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Install OS instead of upgrade
install
# Keyboard layouts

part swap --fstype="swap" --size=1024
part / --fstype="xfs" --size=5000
%packages

@core
%end
在这里的意思,就是最小安装模式;
然后我们保存并退出;
17.启动virt-manager界面;
[[email protected] ~]# virt-manager #启动virt-manager界面
18.在Virtual Machine Manager,点击New,输入Name,勾选Network Install(HTTP,FTP,or NFS),点击Forward;
19.在New VM第二部,输入URL:http://192.168.100.1/dvd,配置KickStart URL:ftp://192.168.100.1/pub/ks.cfg,点击Forward;
20.在New VM第三步,点击Forward;
21.在New VM第四步,点击Forward;
22.在New VM第五步,点击Finish;
23.看到这个界面,表示KickStart配置文件没问题,可以自动化安装vm;
