一、基础环境 1、关闭selinux服务 sed -i ‘s/SELINUX=.*/SELINUX=disabled/‘ /etc/selinux/config setenforce 0 2、关闭iptables服务 chkconfig iptables off iptables -F /etc/init.d/iptables save /etc/init.d/iptables stop 3、serverA桥接模式
4、服务端serverA=192.168.1.120(我这里只使用了eth0网络接口)
5、之前已经下载好了2张dvd CentOS-6.6-x86_64-bin-DVD1.iso和CentOS-6.6-x86_64-bin-DVD2.iso 二、安装cobbler(serverA) 1、安装所需要的包 yum -y install cobbler debmirror pykickstart openssl fence-agents dnsmasq syslinux 2、先看下cobbler命令有哪些 cobbler usage ===== cobbler <distro|profile|system|repo|image|mgmtclass|package|file> ... [add|edit|copy|getks*|list|remove|rename|report] [options|--help] cobbler <aclsetup|buildiso|import|list|replicate|report|reposync|sync|validateks|version|signature|get-loaders|hardlink> [options|--help] 3、cobbler check(检查配置) The following are potential configuration items that you may want to fix: 1)The ‘server‘ field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work. This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it. 2)For PXE to be functional, the ‘next_server‘ field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network. 3)SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment: https://github.com/cobbler/cobbler/wiki/Selinux 4)some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run ‘cobbler get-loaders‘ to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The ‘cobbler get-loaders‘ command is the easiest way to resolve these requirements. 5)change ‘disable‘ to ‘no‘ in /etc/xinetd.d/rsync 6)comment out ‘dists‘ on /etc/debmirror.conf for proper debian support 7)comment out ‘arches‘ on /etc/debmirror.conf for proper debian support 8)The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to ‘cobbler‘ and should be changed, try: "openssl passwd -1 -salt ‘random-phrase-here‘ ‘your-password-here‘" to generate new one Restart cobblerd and then run ‘cobbler sync‘ to apply changes. 4、下载客户端启动文件 cd /var/lib/cobbler/loaders cat filelist.txt http://dgoodwin.fedorapeople.org/loaders/README http://dgoodwin.fedorapeople.org/loaders/COPYING.elilo http://dgoodwin.fedorapeople.org/loaders/COPYING.yaboot http://dgoodwin.fedorapeople.org/loaders/COPYING.syslinux http://dgoodwin.fedorapeople.org/loaders/elilo-3.8-ia64.efi http://dgoodwin.fedorapeople.org/loaders/yaboot-1.3.14-12 http://dgoodwin.fedorapeople.org/loaders/pxelinux.0-3.61 http://dgoodwin.fedorapeople.org/loaders/menu.c32-3.61 http://dgoodwin.fedorapeople.org/loaders/grub-0.97-x86.efi http://dgoodwin.fedorapeople.org/loaders/grub-0.97-x86_64.efi wget -i filelist.txt 5、修改/etc/cobbler/settings配置文件 1)先备份下配置 cp /etc/cobbler/settings /etc/cobbler/settings.bak 2)生成密码 openssl passwd -1 -salt ‘root‘ ‘redhat‘ $1$root$M1uN9dLHipbORRwJW/xR3/ 3)开始修改 sed -i ‘s/^server:.*/server: 192.168.1.120/‘ /etc/cobbler/settings sed -i ‘s/^next_server:.*/next_server: 192.168.1.120/‘ /etc/cobbler/settings sed -i ‘/default_password_crypted/c\default_password_crypted:\ "$1$root$M1uN9dLHipbORRwJW/xR3/"‘ /etc/cobbler/settings sed -i ‘s/^manage_dhcp:.*/manage_dhcp: 1/‘ /etc/cobbler/settings sed -i ‘s/^manage_dns:.*/manage_dns: 1/‘ /etc/cobbler/settings sed -i ‘s/^manage_tftpd:.*/manage_tftpd: 1/‘ /etc/cobbler/settings sed -i ‘s/^restart_dhcp:.*/restart_dhcp: 1/‘ /etc/cobbler/settings sed -i ‘s/^restart_dns:.*/restart_dns: 1/‘ /etc/cobbler/settings sed -i ‘s/^pxe_just_once:.*/pxe_just_once: 1/‘ /etc/cobbler/settings 6、修改/etc/xinetd.d/rsync配置文件 1)先备份下配置 cp /etc/xinetd.d/rsync /etc/xinetd.d/rsync.bak 2)开始修改 sed -i ‘/disable/s/yes/no/g‘ /etc/xinetd.d/rsync 7、修改/etc/cobbler/modules.conf配置文件 1)先备份下配置 cp /etc/cobbler/modules.conf /etc/cobbler/modules.conf.bak 2)开始修改 diff /etc/cobbler/modules.conf /etc/cobbler/modules.conf.bak 56c56 < module = manage_dnsmasq --- > module = manage_bind 69c69 < module = manage_dnsmasq --- > module = manage_isc 8、修改/etc/cobbler/dnsmasq.template配置文件 1)先备份下配置 cp /etc/cobbler/dnsmasq.template /etc/cobbler/dnsmasq.template.bak 2)开始修改 diff /etc/cobbler/dnsmasq.template /etc/cobbler/dnsmasq.template.bak 11c11 < dhcp-range=192.168.1.140,192.168.1.150 --- > dhcp-range=192.168.1.5,192.168.1.200 9、修改kickstart配置文件 1)进入目录 cd /var/lib/cobbler/kickstarts 2)复制模板给centos6.6x86_64.cfg cp sample_end.ks centos6.6x86_64.cfg 3)修改默认的模板为centos模板 cobbler profile edit --name=CentOS6.6-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos6.6x86_64.cfg 4)具体配置 cat centos6.6x86_64.cfg auth --useshadow --enablemd5 bootloader --location=mbr clearpart --all --initlabel text firewall --disabled firstboot --disable keyboard us lang en_US url --url=$tree $yum_repo_stanza $SNIPPET(‘network_config‘) reboot rootpw --iscrypted $default_password_crypted selinux --disabled skipx timezone Asia/shanghai install zerombr part /boot --fstype=ext4 --size=200 part swap --fstype=swap --size=2048 part / --fstype=ext4 --size=10000 part /opt --fstype=ext4 --grow --size=1 %pre $SNIPPET(‘log_ks_pre‘) $SNIPPET(‘kickstart_start‘) $SNIPPET(‘pre_install_network_config‘) $SNIPPET(‘pre_anamon‘) %end %packages --nobase wget vim openssh-server $SNIPPET(‘func_install_if_enabled‘) %end %post --nochroot $SNIPPET(‘log_ks_post_nochroot‘) %end %post $SNIPPET(‘log_ks_post‘) $yum_config_stanza $SNIPPET(‘post_install_kernel_options‘) $SNIPPET(‘post_install_network_config‘) $SNIPPET(‘func_register_if_enabled‘) $SNIPPET(‘download_config_files‘) $SNIPPET(‘koan_environment‘) $SNIPPET(‘redhat_register‘) $SNIPPET(‘cobbler_register‘) $SNIPPET(‘post_anamon‘) $SNIPPET(‘kickstart_done‘) %end 10、挂载并导入dvd iso 1)挂载第1张dvd mount -o loop /opt/CentOS-6.6-x86_64-bin-DVD1.iso /mnt cobbler import --arch=x86_64 --path=/mnt --name=centos6.6 umount /mnt 2)挂载第2张dvd mount -o loop /opt/CentOS-6.6-x86_64-bin-DVD2.iso /mnt cp -rf /mnt/Packages/ /var/www/cobbler/ks_mirror/centos6.6-x86_64/ umount /mnt 11、创建索引 1)进入目录 cd /var/www/cobbler/ks_mirror/centos6.6-x86_64/ 2)createrepo创建索引 createrepo -g repodata/9e2ddcc42b44eb150ebc61dde29c997318d8330b92205b3dbb3a87bcc06d10be-c6-x86_64-comps.xml .
