从事网游运维的兄弟们应该深有感触，往往在开新服的时候需要大批量的布署新的服务器，时间紧迫而且量大，装系统、初始化，枯燥而又乏味，有时还容易出错，为了解放我们的双手，所以要实现自动化，Red Hat 最新发布了网络安装服务器套件 Cobbler（补鞋匠）集成了PXE、DHCP、DNS、Kickstart服务管理和yum仓库管理工具，相对之前的 Kickstart 更加快捷、方便的批量布署red hat、centos类系统
一、安装软件
1、安装cobbler
[root@node1~]#yuminstallcobblerpykickstartdebmirror
2、 其他服务的安装
额外需要的服务还有dhcp tftp，rsync，xinetd，httpd，syslinux。所以如果安装系统的时候如果这几个包没装上，请手动安装。
二、启动服务并检测cobbler
1、启动httpd和cobblerd服务
[root@node1~]#/etc/init.d/httpdstartStartinghttpd:httpd:apr_sockaddr_info_get()failedfornode1[OK][root@node1~]#/etc/init.d/cobblerdstartStartingcobblerdaemon:[OK]
2、执行“cobbler check命令检查存的问题，逐一按提示解决：
[root@node1~]#cobblercheckThefollowingarepotentialconfigurationitemsthatyoumaywanttofix:1:The’server’fieldin/etc/cobbler/settingsmustbesettosomethingotherthanlocalhost,orkickstartingfeatureswillnotwork.ThisshouldbearesolvablehostnameorIPforthebootserverasreachablebyallmachinesthatwilluseit.2:ForPXEtobefunctional,the’next_server’fieldin/etc/cobbler/settingsmustbesettosomethingotherthan127.0.0.1,andshouldmatchtheIPofthebootserveronthePXEnetwork.3:somenetworkboot-loadersaremissingfrom/var/lib/cobbler/loaders,youmayrun’cobblerget-loaders’todownloadthem,or,ifyouonlywanttohandlex86/x86_64netbooting,youmayensurethatyouhaveinstalleda*recent*versionofthesyslinuxpackageinstalledandcanignorethismessageentirely.Filesinthisdirectory,shouldyouwanttosupportallarchitectures,shouldincludepxelinux.0,menu.c32,elilo.efi,andyaboot.The’cobblerget-loaders’commandistheeasiestwaytoresolvetheserequirements.4:change’disable’to’no’in/etc/xinetd.d/rsync5:commentout’dists’on/etc/debmirror.confforproperdebiansupport6:commentout’arches’on/etc/debmirror.confforproperdebiansupport7:Thedefaultpasswordusedbythesampletemplatesfornewlyinstalledmachines(default_password_cryptedin/etc/cobbler/settings)isstillsetto’cobbler’andshouldbechanged,try:”opensslpasswd-1-salt’random-phrase-here”your-password-here'”togeneratenewone8:fencingtoolswerenotfound,andarerequiredtousethe(optional)powermanagementfeatures.installcmanorfence-agentstousethemRestartcobblerdandthenrun’cobblersync’toapplychanges.如上各问题的解决方法如下所示：1、修改/etc/cobbler/settings文件中，server:172.16.22.6；2、修改/etc/cobbler/settings文件中，next_server:172.16.22.6；3、如果当前节点可以访问互联网，执行“cobblerget-loaders”命令即可；否则，需要安装syslinux程序包，执行：[root@node1~]#cp/usr/share/syslinux/{pxelinux.0,menu.c32}/var/lib/cobbler/loaders/4、执行[root@node1~]#chkconfigrsyncon5、注释/etc/debmirror.conf文件中的“@dists=”sid”;”一行；6、注释/etc/debmirror.conf文件中的“@arches=”i386″;”一行；7、执行“opensslpasswd-1-salt’random-phrase-here”your-password-here’”生成密码，并用替换/etc/cobbler/settings文件中default_password_crypted参数的值，如default_password_crypted:”$1$random-p$AOw9RDIWQm6tfUo9Ediu/0″；8、执行“yum-yinstallcmanfence-agents”命令安装相应的程序包即可；莫找借口失败，只找理由成功。(不为失败找理由，要为成功找方法)
