First, install and modify the configuration cobbler
1. Basic source Cobbler not CentOS, the need to import EPEL source upgrade package, ensure epel-release version of the package is the latest, most current version of 6-8:
# Rpm -Uvh http://download.Fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
2. yum install package cobbler
# Yum -y install cobbler
3. [Optional] new version of Fedora installation system located in a "testing" repository for some time to check there is no bug, if you want to install the latest version of cobbler by EPEL (not verified by the production environment there is no bug), in start -testing mode installation or upgrade.
# Sudo yum -y install --enablerepo = epel-testing cobbler
or
# Sudo yum -y update --enablerepo = epel-testing cobbler
4. Install dhcp service
# Yum -y install dhcp
5. Other installation services
There are additional services needed httpd rsync tftp-server xinetd, if the system is not installed, you can do the following to perform the installation.
# Yum -y install httpd rsync tftp-server xinetd
6. Turn cobbler service, restart the Apache service, set up each service boot from the start
# Service httpd start
# Service cobblerd start
# Service xinetd start
# / Sbin / chkconfig httpd on
# / Sbin / chkconfig dhcpd on
# / Sbin / chkconfig xinetd on
# / Sbin / chkconfig tftp on
# / Sbin / chkconfig cobblerd on
7. Close the SELinux and firewall
# Vi / etc / sysconfig / selinux
SELINUX = enforcing Change SELINUX = disabled
Set to become permissive mode SELinux
# Setenforce 0
Off the firewall
# /etc/init.d/iptables Stop
# Chkconfig --del iptables
Restart cobbler Service
# Service cobbler restart
8. Modify the configuration cobbler
# Vi / etc / cobbler / setting
'Next_server: 127.0.0.1' to replace the local IP address (DHCP service address)
'Server: 127.0.0.1' to replace the local IP address (cobbler service address)
'Manage_dhcp: 0' Replace 1 (cobbler management dhcp, later used to synchronize the update configuration information [cobbler sync])
'Manage_rsync: 0' Replace 1 (cobbler rsync management function)
9. loaded partially deleted network boot-loaders
# Cobbler get-loaders
10. Start the tftp service and rsync
# Vi /etc/xinetd.d/tftp
Modified: disable = no
# Vi /etc/xinetd.d/rsync
Modified: disable = no
11. Modify DHCP template, ensure that the DHCP assigned address on the same network segment and the Cobbler
# Vi /etc/cobbler/dhcp.template
ddns-update-style interim;
allow booting;
allow bootp;
ignore client-updates;
set vendorclass = option vendor-class-identifier;
# Need to modify their own network segment 192.168.0.0
subnet 192.168.0.0 netmask 255.255.255.0 {
# Modify your route
option routers 192.168.0.1;
# Domain name server address
option domain-name-servers 202.106.0.20;
Subnet Mask #
option subnet-mask 255.255.255.0;
# Assign IP addresses
range dynamic-bootp 192.168.0.100 192.168.0.254;
filename "/pxelinux.0";
default-lease-time 21600;
max-lease-time 43200;
next-server $ next_server;
}
12. If you want to deploy Debian / Ubuntu system, you need to package debmirror
# Yum install wget
# Yum install ed patch perl perl-Compress-Zlib perl-Cwd perl-Digest-MD5 \
perl-Digest-SHA1 perl-LockFile-Simple perl-libwww-perl
# Wget ftp://fr2.rpmfind.net/linux/epel/5/ppc/debmirror-20090807-1.el5.noarch.rpm
# Rpm -ivh debmirror-20090807-1.el5.noarch.rpm
/etc/debmirror.conf Modify the configuration file, comment out the two lines @dists and @arches
# Vi /etc/debmirror.conf
...
# @ Dists = "sid";
@ Sections = "main, main / debian-installer, contrib, non-free";
# @ Arches = "i386";
...
13. Modify the default password cobbler
After generating a bunch of code added to the cobbler with openssl configuration file (/ etc / cobbler / settings), the replacement default_password_crypted fields:
# Openssl passwd -1 -salt 'random-phrase-here' '1234567890'
$ 1 $ random-p $ RkqDMTpuNlZZhJ7moLn3Q.
# Vi / etc / cobbler / settings
default_password_crypted: "$ 1 $ random-p $ RkqDMTpuNlZZhJ7moLn3Q."
Note: This saved passwords will be used for mass deployment machine, root account password.
14. Install cman start power management features
# Yum install cman
15. Check the cobbler installation environment
# Cobbler check
No configuration problems found. All systems go.
Attention must be fully part repair configuration problems, otherwise there will tftp connection timeout, cobbler can not be installed operating system batch by PXE.
# Cobbler sync
Second, import ISO files
1. Upload the ISO image to the server
2. Create a folder
# Mkdir -p /system/ubuntu12.04
3. Mount ISO image to / system /ubuntu12.04 directory
# Mount -o loop ~ / Downloads / ubuntu-12.04-server-amd64.iso /system/ubuntu12.04/
4. Import the client OS from the iso. This will automatically set the "x86_64", and name ubuntu12.04.
# Cobbler import --path = / system / ubuntu12.04 / --name = ubuntu12.04 --arch = x86_64
It takes a little time, do not worry. View /var/www/cobbler/ks_mirror/ubuntu12.04-x86_64/ directory file generation case.
# Cobbler sync
# Cobbler list
distros:
ubuntu12.04-x86_64
profiles:
ubuntu12.04-x86_64
systems:
repos:
ubuntu12.04-x86_64
images:
mgmtclasses:
packages:
files:
Third, the deployment test
Create a virtual machine test, the virtual machine is set to PXE network boot (and cobbler in the same network), can be seen after Cobbler boot start screen, select ubuntu12.04-x86_64 after entry interface you can see a smooth start install the system without human intervention, Cobbler boot screen as follows:
After the automated installation, using the root user account login, password in the configuration file before writing values
Fourth, the profile
cobbler There are many configuration files, but only a few basic functions need to be modified.
Settings File
Modules Configuration
Cobbler's main setting file is / etc / cobbler / settings. Cobbler2.4.0 introduced dynamic modification mode (Dynamic Settings), we only need to start this mode, you will not need to modify this file manually. The file format is YAML, if directly modify the setting file, you must restart cobbler service to take effect, but if it is modified through the CLI or Web GUI, then the changes will take effect immediately, without restarting the service.
Five Frequently Asked Questions
1, cobblerd checksum error:
cobblerd does not appear to be running / accessible
Solution:
service cobblerd start
service httpd start
2, restart the httpd error:
Starting httpd: Syntax error on line 10 of /etc/httpd/conf.d/cobbler.conf:
Invalid command 'WSGIScriptAliasMatch', perhaps misspelled or defined by a module not included in the server configuration
Solution:
vi /etc/httpd/conf.d/wsgi.conf
#LoadModule Wsgi_module modules / mod_wsgi.so remove the # sign, making it: LoadModule wsgi_module modules / mod_wsgi.so.
3, httpd, SELinux is not running:
httpd does not appear to be running and proxying cobbler, or SELinux is in the way Original traceback.:
Traceback (most recent call last):
Solution:
service httpd start
vi / etc / sysconfig / selinux
SELINUX = enforcing Change SELINUX = disabled, reboot to take effect.
