Cobbler batch installation system centos 6.4 installation Configuration

Recently, I have studied the cobbler batch installation system.
The cobbler installation system is an upgraded version of kickstart earlier. It has the advantages of easy configuration and easy management on its own web interface. The disadvantage is that there are few Chinese materials.
Here we will introduce in detail the installation process I personally experienced.
At the beginning, I used the centos 5.8 system, but reported an error when installing cpbbler-web. So this time I used the centos6.4 System for installation and configuration.

Environment:
Operating System: CentOS 6.4

Ip address of the testing machine: 10.0.0.128
Disable iptables selinux first.

/Etc/init. d/iptables stop

Chkconfig iptables off

Setenforce0

And modify the configuration file/etc/sysconfig/selinux to disable it.
1. Import the yum source and install the software.

Rpm-Uvh http://mirrors.hustunique.com/epel/6/x86_64/epel-release-6-8.noarch.rpm Yum install cobbler-web Yum install dhcp httpd Chkconfig cobblerd on Chkconfig httpd on Cobbler check

Ii. Configure the environment
1> modify the cobbler configuration file

Vi/etc/cobbler/settings

Modify the settings as follows:

Next_server: 10.0.0.128 Server: 10.0.0.128 Manage_dhcp: 1 Manage_rsync: 1

Generate password string

[Root @ puppet ~] # Openssl passwd-1-salt "cobber" "123456" # A simple example "123456"

$1 $ cobber $ yV9XfOuaaiVDvImopK7o. 1
Openssl passwd-1-salt 'any character 'Password'
You can write any character for this command. This password is the root password after the system is installed. Replace the string in the configuration file.
Vi/etc/cobbler/settings
Default_password_crypted: "$1 $ cobber $ yV9XfOuaaiVDvImopK7o. 1"
2> enable tfpt and rsync
Vim/etc/xinetd. d/tftp
Vim/etc/xinetd. d/rsync
Change the disable value to no.
Start the service
/Etc/init. d/xinetd restart
3> modify the dhcp configuration file

# Vi/etc/cobbler/dhcp. template

Ddns-update-style interim; Allow booting; Allow bootp; Ignore client-updates; Set vendorclass = option vendor-class-identifier; Option pxe-system-type code 93 = unsigned integer 16; Subnet 10.0.0.0 netmask 255.255.255.0 { Option routers 10.0.0.1; Option domain-name-servers 8.8.8.8; Option subnet-mask limit 255.0; Range dynamic-bootp 10.0.0.2 10.0.0.100; Default-lease-time 21600; Max-lease-time 43200; Next-server $ next_server; }

For the remaining default values, you only need to modify this template. cobbler will synchronize to the dhcp configuration.
[Root @ cobbler ~] # Cobbler get-loaders

3. Configure the web Environment
# Vi/etc/cobbler/modules. conf

Module = authn_configfile/change the Authentication mode to the password file type

# Htdigest/etc/cobbler/users. digest "Cobbler" cobbler/Add a cobbler user and prompt to enter the password twice for confirmation

# Cobbler sync/output *** task complete *** indicates no configuration error

#/Etc/init. d/httpd restart

#/Etc/init. d/cobblerdrestart

Access the web page https: // 10.0.0.128/cobbler_web/log on with the user you just created

1: Add a DVD source,

[Root @ puppet soft] # mount/dev/cdrom/mnt/cdrom/

Cobbler import -- path =/mnt/cdrom -- name = centos6.4

[Root @ cobbler ~] # Cobblerimport -- path =/mnt/cdrom -- name = centos6.4

For graphic interface operations, click Importer DVD (attach the image ISO first), then Importer, and click run

After the import is complete, you can see

Select the profile configuration ks file on the left

Enter the required ks file path

The Centos6.ks file is as follows. Here is just a simple ks file. You can configure it as needed.

5: after the client starts from the network, select the corresponding project file to start automatic deployment.

Select the configured option to start Automatic Installation

After the restart is completed, you can use the previously defined password ("123456") to log on.

Appendix: troubleshooting
# Cobbler check
The following are potential configuration items that you may be want to fix:
1: Must enable a selinux boolean to enable vital web services components, run: setsebool-P httpd_can_network_connect true
2: you need to set some SELinux content rules to ensure cobbler serves available in your SELinux environment, run the following:/usr/sbin/semanagefcontext-a-t external "/tftpboot /. * "&/usr/sbin/semanage fcontext-a-t public_content_t"/var/www/cobbler "/images /. *
3: you need to set some SELinux rules if you want to use cobbler-web (anoptional package), run the following: /usr/sbin/semanage fcontext-a-thttpd_sys_content_rw_t "/var/lib/cobbler/webui_sessions /. *"
Solution: Disable selinux.
# Vim/etc/sysconfig/selinux
SELINUX = disabled
4: change 'disable' to 'no' in/etc/xinetd. d/tftp
Solution: edit the/etc/xinetd. d/tftp file and change the disable field configuration in the file from yes to no.
5: change 'disable' to 'no' in/etc/xinetd. d/rsync
Solution: edit the/etc/xinetd. d/rsync file and change the disable field configuration in the file from yes to no.
6: since iptables may be running, ensure 69, 80, and 25151 are unblocked
Solution: Enable ports 25151, 80, and in iptables. If it is only used in the internal environment, we recommend that you disable the firewall directly.
7: debmirror package is not installed, it will be required to manage debiandeployments and repositories
Solution: yum install debmirror
Or: rpm-Uvhftp: // rpmfind.net/linux/epel/5/ I #/debmirror-20090807-1.el5.noarch.rpm-nodeps-force
8: ksvalidator was not found, install pykickstart
Solution: yum install pykickstart
9: The default password used by the sample templates for newly installedmachines (default_password_crypted in/etc/cobbler/settings) is still set to 'jobbler' and shocould be changed, try: "openssl passwd-1-salt 'random-phrase-here ''ur-password-here '" to generate new one
Solution: change the default password and write the password to/etc/cobbler/settings.
# Openssl passwd-1-salt 'random-phrase-here ''your-password-here'
10: comment 'dists 'on/etc/debmirror. conf for proper debian support
11: comment 'archies' on/etc/debmirror. conf for proper debian support
Solution: Comment on the two lines below/etc/debmirror. conf.
# @ Dists = "sid ";
@ Sections = "main, main/debian-installer, contrib, non-free ";
# @ Arches = "i386 ";
12: fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
Solution: yum install cman
After the repair is completed, check the problem with cobbler check and use cobbler sync for synchronization:
# Cobbler check
No configuration problems found. All systems go.

13. comment out 'dists 'on/etc/debmirror. conf for proper debian support

Comment out 'archies' on/etc/debmirror. conf for proper debiansuppvim Vim vi/etc/debmirror. conf

# Comment out @ dists = "sid" and @ arches = "i386.

# @ Dists = "sid ";

# @ Arches = "i386 ";
