一、安裝環境
centos 5.4
關掉iptables 關掉 selinux selinux 導致tftp的目錄無法訪問 pxe停止在引導介面
二、cobbler使用目錄及檔案
cobbler相關配置檔案 /etc/cobbler
cobbler資料儲存目錄 /var/www/cobbler
dhcp配置檔案 /etc/dhcpd.conf
dhcp租期快取檔案 /var/lib/dhcpd/dhcpd.leases
pxe配置檔案 /tftpboot/pxelinux.cfg/default
三、安裝cobbler
# rpm -ivh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm
# yum -y install tftp-server httpd dhcp yum-utils
# yum -y install cobbler
# yum -y install cman
yum-utils 編譯安裝 make && make install
四、修改配置檔案
1.修改cobbler配置檔案
# vi /etc/cobbler/settings
[code]
server: `192.168.1.3` #cobbler伺服器地址
next_server: `192.168.1.3`
manage_dhcp: 1
[/code]
2.更改tftp啟動方式
# vi /etc/xinetd.d/tftp
[code]
disable = no #預設開啟tftp
[/code]
3.編輯dhcp配置模板
# vi /etc/cobbler/dhcp.template 改為相應的網段和ip
subnet 192.168.2.0 netmask 255.255.255.0 {
option routers 192.168.2.5;
option domain-name-servers 192.168.2.1;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.2.100 192.168.2.254;
filename “/pxelinux.0”;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
}
五、匯入CentOS 光碟映像檔案
# mkdir /home/CentOS
# mount /home/src/CentOS-5.4-x86_64-bin-DVD.iso /home/CentOS/ -o loop
#cobbler import –path=/home/CentOS –name=CentOS5.4_x86_64
# cobbler sync 應用配置模板
六、cobbler check 根據提示解決問題
例如：
#2: Must enable selinux boolean to enable Apache and web services components, run: setsebool -P httpd_can_network_connect true
Nice to see that it has good instructions for selinux
#3: you need to set some SELinux content rules to ensure cobbler works correctly in your SELinux environment, run the following: /usr/sbin/semanage fcontext -a -t public_content_t “/var/lib/tftpboot/.*” && /usr/sbin/semanage fcontext -a -t public_content_t “/var/www/cobbler/p_w_picpaths/.*”
Detailed command to enable http server to reed content from /var/www/cobbler and have tfpboot find its files
#4: service cobblerd is not running
Obviously this isn`t running because we did not start it yet
#5: change `disable` to `no` in /etc/xinetd.d/tftp
#6: service httpd is not running
#7: since iptables may be running, ensure 69 (dhcp), 80(http), 25150(cobbler api), and 25151(cobbler api R/W) are unblocked 關閉防火牆
#8: reposync is not installed, need for cobbler reposync, install/upgrade yum-utils?
Easy to solve with: yum install yum-utils
#9: yumdownloader is not installed, needed for cobbler repo add with –rpm-list parameter, install/upgrade yum-utils? 安裝yum-utils
#10: fencing tools were not found, and are required to use the (optional) power management features. install cman to use them 安裝cman
七、啟動cobbler服務
service dhcpd start
service httpd start
service xinetd restart
service cobbler start
八、kickstart配置檔案例項
# vi /etc/cobbler/sample.ks
#platform=x86, AMD64, or Intel EM64T
# System authorization information
auth –useshadow –enablemd5
# System bootloader configuration
bootloader –location=mbr
# Partition clearing information
clearpart –all –initlabel
# Use text mode install
text
# Firewall configuration
firewall –disable
# Run the Setup Agent on first boot
firstboot –enabled
# System keyboard
keyboard us
# System language
lang en_US
# Use network installation
url –url=$tree
# If any cobbler repo definitions were referenced in the kickstart profile, include them here.
$yum_repo_stanza
# Network information
network –bootproto=dhcp –device=eth0 –onboot=on
# Reboot after installation
reboot
#Root password

# SELinux configuration
selinux –disabled
# Do not configure the X Window System

# System timezone

# Install OS instead of upgrade
install
# Clear the Master Boot Record

# Magically figure out how to partition this thing

九、利用cobbler重灌系統
# rpm -Uhv koan-1.2.5-1.el5.noarch.rpm
# koan -server=192.168.1.3 -list-profiles
# koan -replace-self -server=192.168.1.3 -profile=CentOS_5.2-i386
# reboot
