Cobbler是什么？
Cobbler（補鞋匠）集成了PXE、DHCP、DNS、Kickstart服務管理和yum倉庫管理工具，相對之前的 Kickstart 更加快捷、方便的批量布署red hat、centos類系統 測試環境： VMware? Workstation : 9.0.0 build-812388 操作系統 : CentOS 5.6 32位

[root@server1?~]#?wget?http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm? [root@server1?~]#?rpm?-ivh?epel-release-5-4.noarch.rpm? warning:?epel-release-5-4.noarch.rpm:?Header?V3?DSA?signature:?NOKEY,?key?ID?217521f6? Preparing...????????????????###########################################?[100%]? ???1:epel-release???????????###########################################?[100%]? [root@server1?~]#? 安裝epel源的好處 就是epel這個項目是由fedora維護的，在維護的這個源中包含許多軟件，包括ntop，nagios之類的，也就是說，你安裝了epel源就可以直接用yum install ntop來安裝了，不過這個應該針對紅帽企業版Linux(RHEL)及其衍生發行版(比如CentOS、Scientific Linux)系統，ubuntu這類的應該不行。 二.安裝與配置cobbler 1.安裝cobbler和一些必須的包，并設置開機自動啟動
[root@server1?~]#?yum?-y?install?cobbler?httpd?rsync?tftp-server?xinetd?dhcp?python-ctypes?pykickstart?cman???? ...? cobbler-2.2.2-1.el5.rf.noarch?from?rpmforge?has?depsolving?problems? ??--> ?Missing?Dependency:?python-netaddr?is?needed?by?package?cobbler-2.2.2-1.el5.rf.noarch?(rpmforge)? cobbler-2.2.2-1.el5.rf.noarch?from?rpmforge?has?depsolving?problems? ??--> ?Missing?Dependency:?mod_wsgi?is?needed?by?package?cobbler-2.2.2-1.el5.rf.noarch?(rpmforge)?

[root@server1?~]#?vim?/etc/cobbler/settings? ? next_server:?127.0.0.1??修改為：next_server:?192.168.0.45（是cobbler服務器的地址）? ? server:?127.0.0.1????修改為：?server:?192.168.0.45（是cobbler服務器的地址）? ? manage_dhcp:?0??修改為?manage_dhcp:?1?（1意思就是由cobbler自動管理dhcpd）? ? manage_rsync:?0??修改為?manage_rsync:?1??（1意思就是由cobbler自動管理rsync）? 3.編輯/etc/httpd/conf/httpd.conf
[root@server1?~]#?vim?/etc/httpd/conf/httpd.conf???在LoadModule附近?添加以下行? LoadModule?suexec_module?modules/mod_suexec.so? LoadModule?disk_cache_module?modules/mod_disk_cache.so?

啟動 dhcpd：?????????????????????????????????????????????? [失敗] 查看/var/log/message 看到啟動dhcp的過程中發現以下錯誤， Dec? 9 06:19:23 server1 dhcpd: ** You must add a global ddns-update-style statement to /etc/dhcpd.conf.
Dec? 9 06:19:23 server1 dhcpd:??? To get the same behaviour as in 3.0b2pl11 and previous
Dec? 9 06:19:23 server1 dhcpd:??? versions, add a line that says "ddns-update-style ad-hoc;"
Dec? 9 06:19:23 server1 dhcpd:??? Please read the dhcpd.conf manual page for more information. ** 主要原因是： 文件/etc/cobbler/settings里面 manage_dhcp: 0? 沒有修改為1 造成的 修改為1之后， 重啟cobblerd,然后做一次?cobbler sync(cobbler會把
dhcp.template里面的內容復制到了/etc/dhcpd.conf) ，就會自動的把dhcpd啟動起來.
