最近在學習RHCE課程,上一篇簡單的講一下如何用HTTP來作為KVM的VM網絡安裝過程,請閱讀:http://gshao.blog.51cto.com/3512873/1882093
今天講到FTP+HTTP+KickStart釋出,當然還有PXE安裝RHEL(後續講)。
環境:
虛拟主控端:RHEL 7.0
硬體:4vCPU+8G+40Gdisk
IP位址:172.16.38.10
vnet ip位址:192.168.100.1
先截圖上一篇裝完rhel系統的樣子:

回歸到正文,今天講HTTPD+FTP+KickStart釋出鏡像。
1.先安裝httpd服務,由于我們上一篇已安裝,我們先確定httpd服務能正常啟動,并測試web伺服器的dvd目錄是否正常通路;
httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled)

Hint: Some lines were ellipsized, use -l to show in full.
别記錯哦,這裡是對外的ip位址,不是對内的vnet ip位址;
2.安裝FTP服務;
3.啟動vsftpd服務,啟用vsftpd服務,測試ftp是否可以正常通路;
ln -s '/usr/lib/systemd/system/vsftpd.service' '/etc/systemd/system/multi-user.target.wants/vsftpd.service'
[root@localhost ~]# systemctl status vsftpd
vsftpd.service - Vsftpd ftp daemon
Loaded: loaded (/usr/lib/systemd/system/vsftpd.service; enabled)

Dec 13 19:41:51 localhost.localdomain systemd[1]: Started Vsftpd ftp daemon.
4.安裝KickStart服務;
5.啟動Kickstart配置檔案控制台;
6.在Kickstart Configurator-Basic Configuration界面,配置Time Zone時間為Asia/Shanghai,輸入Root Passowrd,勾選Reboot system after installation和Perform installation in text mode(grahical is default);
7.在Kickstart Configurator-Installation Method,勾選Perform new installation,勾選HTTP,輸入HTTP Server位址:192.168.100.1,HTTP Diretory為dvd/;
8.在Kickstart Configurator-Boot Loader Options,勾選install new boot loader,勾選Install boot loader on Master Boot Record(MBR);
9.在Kickstart Configurator-Partition Information,勾選Clear Master Boot Record,勾選Remove all existing partitions,勾選Initialize the disk label,Add swap和/分區,并配置設定空間;
10.在Kickstart Configurator-Network Configuration,點選Add Network Device,輸入Network Device名,配置Network Type為DHCP;
11.在Kickstart Configurator-Firewall Configuration,配置SELinux為Warn,配置Security level為Disable firewall;
12.其他部分保持預設,如果你要添加shell,可以在Pre-Installation Script或者Post-Installation Script添加對應的shell腳本
13.點選File-Save;
14.因為我們之前搭建vsftp服務,我們直接存放在/var/ftp/pub裡面;
15.補充一點,Package Selection預設在Kickstart配置器是不能勾選的;
16.我們可以通過在/root目錄有個anaconda-ks.cfg,這個也是Kickstart配置檔案,進行将Package Selection的部分内容複制到我們剛才制作的ks.cfg配置檔案中;

我們将這部分複制出來,張貼到ks.cfg配置檔案;

%end
在這裡的意思,就是最小安裝模式;
然後我們儲存并退出;
17.啟動virt-manager界面;
18.在Virtual Machine Manager,點選New,輸入Name,勾選Network Install(HTTP,FTP,or NFS),點選Forward;
19.在New VM第二部,輸入URL:http://192.168.100.1/dvd,配置KickStart URL:ftp://192.168.100.1/pub/ks.cfg,點選Forward;
20.在New VM第三步,點選Forward;
21.在New VM第四步,點選Forward;
22.在New VM第五步,點選Finish;
23.看到這個界面,表示KickStart配置檔案沒問題,可以自動化安裝vm;
