CentOS+Cobbler安装配置
系统信息：CentOS release 6.5 (Final）
内核信息：2.6.32-431.el6.x86_64
1.安装epel；
[root@cobbler-server apps]# wget http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm [root@cobbler-server apps]# rpm -ivh epel-release-6-8.noarch.rpm
2.安装cobbler相关服务；
[root@cobbler-server apps]# yum install -y cobbler httpd tftp-server xinetd dhcp rsync
3.启动相关服务并且检查配置；
[root@cobbler-server ~]# chkconfig httpd on [root@cobbler-server ~]# chkconfig cobblerd on [root@cobbler-server ~]# chkconfig xinetd on [root@cobbler-server apps]#/etc/init.d/cobblerd restart Stopping cobbler daemon: [ OK ] Starting cobbler daemon: [ OK ] [root@cobbler-server apps]#/etc/init.d/httpd restart Stopping httpd: [ OK ] Starting httpd: httpd:apr_sockaddr_info_get() failed for cobbler-server httpd: Could not reliably determine theserver's fully qualified domain name, using 127.0.0.1 for ServerName [ OK ]
[root@cobbler-server apps]# cobbler check The following are potential configurationitems that you may want to fix: 1 : The 'server' field in /etc/cobbler/settingsmust be set to something other than localhost, or kickstarting features willnot work. This should be a resolvablehostname or IP for the boot server as reachable by all machines that will useit. 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 : some network boot-loaders are missingfrom /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to downloadthem, or, if you only want to handle x86/x86_64 netbooting, you may ensure thatyou have installed a *recent* version of the syslinux package installed and canignore this message entirely. Files inthis directory, should you want to support all architectures, should includepxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' commandis the easiest way to resolve these requirements. 4 : change 'disable' to 'no' in/etc/xinetd.d/rsync 5 : debmirror package is not installed, itwill be required to manage debian deployments and repositories 6 : ksvalidator was not found, installpykickstart 7 : The default password used by the sampletemplates 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 8 : fencing tools were not found, and arerequired to use the (optional) power management features. install cman or fence-agentsto use them Restart cobblerd and then run 'cobblersync' to apply changes.
根据上面的提示我们一一进行解决：
1）编辑/etc/cobbler/settings文件，找到server选项，修改成服务器实际IP即可（384行左右）。
384 rver: 10.0.1.7
2）编辑/etc/cobbler/settings文件，找到next_server选项，修改成服务器实际IP即可（272行左右）。
272 xt_server: 10.0.1.7
3）执行cobbler get-loaders,系统自动下载loader程序，完成修复工作。
[root@cobbler-server apps]# cobbler get-loaders
4）编辑/etc/xinetd.d/rsync,把文件中disable字段配置yes改成no。
[root@cobbler-server apps]# vim /etc/xinetd.d/rsync
service rsync
{
disable = no
flags = IPv6
socket_type = stream
wait = no
user = root
server = /usr/bin/rsync
server_args = --daemon
log_on_failure += USERID
}
5） 提示debmirror没有安装，如果不是debian之类的系统可以忽略。
6）提示需要安装pykickstart。
[root@cobbler-server apps]# yum install -y pykickstart
7）修改cobbler默认密码，并且更改/etc/cobbler/settings文件。
[root@cobbler-server apps]# openssl passwd -1 -salt 'random-phrase-here' '123456'
$1$random-p$mzxQ/Sx848sXgvfwJCoZM0
[root@cobbler-server apps]# vim /etc/cobbler/settings （101行）
101 default_password_crypted:"$1$random-p$mzxQ/Sx848sXgvfwJCoZM0"
8）提示需要安装cman。
[root@cobbler-server apps]# yum install -y cman
4.重启cobbler并且检查配置文件。
[root@cobbler-server apps]#/etc/init.d/cobblerd restart Stopping cobbler daemon: [ OK ] Starting cobbler daemon: [ OK ] [root@cobbler-server apps]# cobbler check The following are potential configurationitems that you may want to fix: 1 : debmirror package is not installed, itwill be required to manage debian deployments and repositories Restart cobblerd and then run 'cobblersync' to apply changes.
5.导入安装文件；
[root@cobbler-server apps]# ls CentOS-6.5-x86_64-bin-DVD1.iso epel-release-6-8.noarch.rpm [root@cobbler-server apps]#mount -o loop -tiso9660 CentOS-6.5-x86_64-bin-DVD1.iso /mnt [root@cobbler-server apps]# cobbler import --path=/mnt --name=CentOS-6.5-x86_64-bin-DVD1
6.配置DHCP服务；
编辑/etc/cobbler/settings修改242行为1如下：
[root@cobbler-server apps]# vim /etc/cobbler/settings 242 manage_dhcp: 1
编辑/etc/cobbler/dhcp.template修改cobbler dhcp管理模板
[root@cobbler-server apps]# vim /etc/cobbler/dhcp.template
修改如下内容：
subnet 10.0.1.0 netmask 255.255.255.0 {
option routers 10.0.1.254;
optiondomain-name-servers 202.106.0.20;
option subnet-mask 255.255.255.0;
range dynamic-bootp 10.0.1.100 10.0.1.120;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
[root@cobbler-server apps]#/etc/init.d/xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
7.同步cobbler配置；
[root@cobbler-server apps]# cobbler sync task started: 2014-09-03_153036_sync task started (id=Sync, time=Wed Sep 3 15:30:36 2014) running pre-sync triggers cleaning trees removing:/var/www/cobbler/images/CentOS-6.5-bin-DVD1-x86_64 removing:/var/lib/tftpboot/pxelinux.cfg/default removing: /var/lib/tftpboot/grub/images removing:/var/lib/tftpboot/grub/grub-x86_64.efi removing: /var/lib/tftpboot/grub/efidefault removing:/var/lib/tftpboot/grub/grub-x86.efi removing:/var/lib/tftpboot/images/CentOS-6.5-bin-DVD1-x86_64 removing: /var/lib/tftpboot/s390x/profile_list copying bootloaders trying hardlink/var/lib/cobbler/loaders/grub-x86_64.efi ->/var/lib/tftpboot/grub/grub-x86_64.efi trying hardlink/var/lib/cobbler/loaders/grub-x86.efi -> /var/lib/tftpboot/grub/grub-x86.efi copying distros to tftpboot copying files for distro:CentOS-6.5-bin-DVD1-x86_64 trying hardlink/var/www/cobbler/ks_mirror/CentOS-6.5-x86_64-bin-DVD1/images/pxeboot/vmlinuz-> /var/lib/tftpboot/images/CentOS-6.5-bin-DVD1-x86_64/vmlinuz trying hardlink/var/www/cobbler/ks_mirror/CentOS-6.5-x86_64-bin-DVD1/images/pxeboot/initrd.img-> /var/lib/tftpboot/images/CentOS-6.5-bin-DVD1-x86_64/initrd.img copying images generating PXE configuration files generating PXE menu structure copying files for distro: CentOS-6.5-bin-DVD1-x86_64 trying hardlink/var/www/cobbler/ks_mirror/CentOS-6.5-x86_64-bin-DVD1/images/pxeboot/vmlinuz-> /var/www/cobbler/images/CentOS-6.5-bin-DVD1-x86_64/vmlinuz trying hardlink/var/www/cobbler/ks_mirror/CentOS-6.5-x86_64-bin-DVD1/images/pxeboot/initrd.img-> /var/www/cobbler/images/CentOS-6.5-bin-DVD1-x86_64/initrd.img Writing template files forCentOS-6.5-bin-DVD1-x86_64 rendering DHCP files generating /etc/dhcp/dhcpd.conf rendering TFTPD files generating /etc/xinetd.d/tftp processing boot_files for distro:CentOS-6.5-bin-DVD1-x86_64 cleaning link caches running post-sync triggers running python triggers from/var/lib/cobbler/triggers/sync/post/* running python triggercobbler.modules.sync_post_restart_services running: dhcpd -t -q received on stdout: received on stderr: running: service dhcpd restart received on stdout: Starting dhcpd: [ OK ] received on stderr: running shell triggers from/var/lib/cobbler/triggers/sync/post/* running python triggers from/var/lib/cobbler/triggers/change/* running python triggercobbler.modules.scm_track running shell triggers from/var/lib/cobbler/triggers/change/* *** TASK COMPLETE ***
到此cobbler配置已经完成，可以用虚拟机进行测试。
8.安装cobbler-web;
[root@cobbler-server ~]# yum install -y cobbler-web [root@cobbler-server ~]# /etc/init.d/httpd restart Stopping httpd: [ OK ] Starting httpd: httpd:apr_sockaddr_info_get() failed for cobbler-server httpd: Could not reliably determine theserver's fully qualified domain name, using 127.0.0.1 for ServerName [ OK ]
