CentOS7下利用cobbler部署CentOS

1)安装epel源和cobbler [root@cobbler~]#yum-yinstallhttp://mirrors.163.com/centos/7/extras/x86_64/Packages/epel-release-7-9.noarch.rpm [root@cobbler~]#yuminstallcobblercobbler-webdhcptftp-serverpykickstarthttpdxinetd-y [root@cobbler~]#systemctlstartxinetd.service [root@cobbler~]#systemctlenablexinetd.service [root@cobbler~]#systemctlstarthttpd [root@cobbler~]#systemctlenablehttpd Createdsymlinkfrom/etc/systemd/system/multi-user.target.wants/httpd.serviceto/usr/lib/systemd/system/httpd.service. [root@cobbler~]#systemctlstartcobblerd.service [root@cobbler~]#systemctlenablecobblerd.service Createdsymlinkfrom/etc/systemd/system/multi-user.target.wants/cobblerd.serviceto/usr/lib/systemd/system/cobblerd.service. 2)配置cobbler 检查cobbler: [root@cobbler~]#cobblercheck Thefollowingarepotentialconfigurationitemsthatyoumaywanttofix: 1:The'server'fieldin/etc/cobbler/settingsmustbesettosomethingotherthanlocalhost,orkickstartingfeatureswillnotwork.ThisshouldbearesolvablehostnameorIPforthebootserverasreachablebyallmachinesthatwilluseit. 2:ForPXEtobefunctional,the'next_server'fieldin/etc/cobbler/settingsmustbesettosomethingotherthan127.0.0.1,andshouldmatchtheIPofthebootserveronthePXEnetwork. 3:change'disable'to'no'in/etc/xinetd.d/tftp 4: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. 5:enableandstartrsyncd.servicewithsystemctl 6:debmirrorpackageisnotinstalled,itwillberequiredtomanagedebiandeploymentsandrepositories 7:Thedefaultpasswordusedbythesampletemplatesfornewlyinstalledmachines(default_password_cryptedin/etc/cobbler/settings)isstillsetto'cobbler'andshouldbechanged,try:"opensslpasswd-1-salt'random-phrase-here''your-password-here'"togeneratenewone 8:fencingtoolswerenotfound,andarerequiredtousethe(optional)powermanagementfeatures.installcmanorfence-agentstousethem Restartcobblerdandthenrun'cobblersync'toapplychanges. 修改cobbler的配置文件: [root@cobbler~]#vim/etc/cobbler/settings #ifyoudonotsetthiscorrectly,thiswillbemanifestedinTFTPopentimeouts. 将“next_server:127.0.0.1”修改为“next_server:10.10.10.222” 将“server:127.0.0.1”修改为“server:10.10.10.222” #setto1toenableCobbler'sDHCPmanagementfeatures. #thechoiceofDHCPmanagementengineisin/etc/cobbler/modules.conf 将“manage_dhcp:0”修改为“manage_dhcp:1” 修改cobbler默认的密码: 将“default_password_crypted:"$1$mF86/UHC$WvcIcX2t6crBz2onWxyac."”修改为“default_password_crypted:"$1$wanwan$K9lP0CajD0pbFaxI0if84/"” 随机生成一个密码: [root@cobbler~]#opensslpasswd-1-salt'wanwan''redhat12345' $1$wanwan$K9lP0CajD0pbFaxI0if84/ [root@cobbler~]#vim/etc/xinetd.d/tftp 将“disable=yes”修改为“disable=no” 重启rsync服务: [root@cobbler~]#systemctlstartrsyncd.service [root@cobbler~]#systemctlenablersyncd.service
