Kickstart 操作

為了玩RHEL5 cluster方便安裝，順便玩了一下kickstart大量佈署方式安裝系統

參考文件：

1.鳥哥網站的網友分享篇裡面彥明大的幾篇文章

2.CentOS官網

設定方式如下：

1.DHCP server (如已有可跳過)

# cp /usr/share/doc/dhcp-3.0pl2/dhcpd.conf.sample /etc/dhcpd.conf

# more /etc/dhcpd.conf 內容如下根據自己需求更改

ddns-update-style interim; ignore client-updates; subnet 192.168.0.0 netmask 255.255.255.0 { # --- default gateway option routers 192.168.0.1; option subnet-mask 255.255.255.0; option nis-domain "domain.org"; option domain-name "domain.org"; option domain-name-servers 192.168.1.1; option time-offset -18000; # Eastern Standard Time # option ntp-servers 192.168.1.1; # option netbios-name-servers 192.168.1.1; # --- Selects point-to-point node (default is hybrid). Don't change this unless # -- you understand Netbios very well # option netbios-node-type 2; range dynamic-bootp 192.168.0.128 192.168.0.254; default-lease-time 21600; max-lease-time 43200;

#/etc/init.d/dhcpd restart

#chkconfig dhcpd on

2.準備install server (建議與DHCP server放一起，可以再建立yum)

可以使用http，ftp，nfs方式來作，我測試以ftp為主，可以設定帳密來登入：

#yum install vsftpd

#chkconfig vsftpd on

#/etc/init.d/vsftpd restart (預設有開匿名登入，可根據自己需求調整)

#mount -t iso9660 -o loop CentOS.iso /mnt (放光碟或mount ISO)

#mkdir /var/ftp/pub/CentOS (建立資料夾)

#cp -av /mnt/. /var/ftp/pub/CentOS (將安裝資料放到ftp)

#yum install system-config-kickstart (設定kickstart參數的gui)

#system-config-kickstart (設定安裝相關資料)

在GUI畫面下設定完成後選file → save 可存成一個自動安奘的文字檔

我的設定如下

#platform=x86, AMD64, or Intel EM64T # System authorization information auth --useshadow --enablemd5 # System bootloader configuration bootloader --location=mbr # Clear the Master Boot Record zerombr # Partition clearing information clearpart --all --initlabel # Use graphical install graphical # Firewall configuration firewall --enabled --ssh --trust=eth0 # Run the Setup Agent on first boot #firstboot --enable # System keyboard keyboard us # System language lang zh_TW.UTF-8 #Language modules to install langsupport en_US --default=zh_TW.UTF-8 # Installation logging level logging --level=info # Use network installation url --url=ftp://10.101.20.244/pub/mnt # Network information network --bootproto=dhcp --device=eth0 --onboot=on # Reboot after installation reboot #Root password rootpw --iscrypted $1$FZr8YqVs$W4ykp.eMFp97IIkE8xIvn. # SELinux configuration selinux --disabled # System timezone timezone Asia/Taipei # Install OS instead of upgrade install # X Window System configuration information xconfig --defaultdesktop=GNOME --depth=8 --resolution=800x600 --startxonboot # Disk partitioning information part /boot --bytes-per-inode=4096 --fstype="ext3" --size=100 part swap --bytes-per-inode=4096 --fstype="swap" --size=2048 part / --bytes-per-inode=4096 --fstype="ext3" --grow --size=1 %packages @chinese-support @office @editors @text-internet @gnome-desktop @dialup @core @base @games @base-x @graphics @printing @sound-and-video @graphical-internet device-mapper-multipath xorg-x11-server-Xnest libsane-hpaio -sysreport

將此檔案跟開機光碟燒在一起，也可以放在ftp上

3.安裝：

放入做好之開機光碟，開機

執行：

linux ks=/cdrom

or

linux ks=ftp://10.101.20.244/pub/ks.cfg

(將檔案放在ftp上)

這樣應該會自己安裝好嚕
