Cobbler and cobbler

Cobbler and cobbler

Introduction:

For the automation of operating system installation, we used Kickstart launched by RedHat to install the operating system in batches. In recent years, RedHat has released a Cobbler.

Cobbler is developed using Python, which is small and lightweight and can complete system installation and even manage some services. (It is known as a tool that can be learned by shoe supplements)

Cobbler supports command line management, web interface management, and API interfaces to facilitate second-step activation.

# Disable SELinux and iptables !!!

1. Support Environment Installation

Shell> yum-y install epel-release # install epel source shell> yum-y install cobbler httpd rsync tftp-server xinetd dhcp pykickstart fence-agents

2. Configure Tftp and Rsync

Shell> vim/etc/xinetd. d/tftpservice tftp {socket_type = dgramprotocol = udpwait = yesuser = rootserver =/usr/sbin/in. tftpdserver_args =-s/var/lib/tftpbootdisable = no # originally yesper_source = 11cps = 100 2 flags = IPv4} shell> vim/etc/xinetd. d/rsyncservice rsync {disable = no # original yesflags = IPv6socket_type = streamwait = nouser = rootserver =/usr/bin/rsyncserver_args = -- users + = USERID} shell> vim/etc/ httpd/confServerName 127.0.0.1: 80

# Everyone knows this.

2. Configure Cobbler

shell > openssl passwd -1 -salt 'random-phrase-here' '123456'$1$random-p$mzxQ/Sx848sXgvfwJCoZM0

# Generate the root password (this password is the root password of the newly installed client)

Shell> vim/etc/cobbler/settingsmanage_dhcp: 1 # original 0manage_tftpd: 1manage_rsync: 1 # original 0next_server: 192.168.214.10 # local IPserver: 192.168.214.10 # local region: "$1 $ random-p $ mzxQ/Sx848sXgvfwJCoZM0" # generated root Password

3. Configure DHCP

Shell> vim/etc/cobbler/dhcp. template # directly modify this file to subnet 192.168.214.0 netmask 255.255.255.0 {option routers 192.168.214.2; option subnet-mask 255.255.255.255.0; range dynamic-bootp 192.168.214.100 192.168.214.120; default-lease-time 21600; max-lease-time 43200; next-server $ next_server;

# Only modify the IP address of this region as the appropriate IP Address

3. Import the installation Source

shell > mount /dev/cdrom /mnt/shell > cobbler import --path=/mnt/ --arch=x86_64 --name=Centos-6.6-minimal

# Output information omitted (Cobbler copies the image to the/var/www/cobbler/ks_mirror/Centos-6.6-minimal-x86_64 directory)
(A release and profile file named Centos-6.6-minimal-x86_64 will also be created)

shell > cobbler listdistros:Centos-6.6-minimal-x86_64profiles:Centos-6.6-minimal-x86_64systems:repos:images:mgmtclasses:packages:files:

4. Create ks files

Shell> vim/var/lib/cobbler/kickstarts/Centos-6.6_minimal-x86_64.ks # platform = x86, AMD64, or Intel EM64T # version = DEVEL # Firewall configurationfirewall -- disabled # Install OS instead of upgradeinstall # Use network installationurl -- url = "http: // 192.168.214.10/cobbler/ks_mirror/Centos-6.6-minimal-x84_64/"# Root passwordrootpw -- iscrypted $1 $ hk0MvN4A $ Dz. login # System authorization informationauth -- useshadow -- passalgo = sha512 # Use text mode installtext # System authentication us # System authentication agelang zh_CN # SELinux configurationselinux -- disabled # Do not configure the X Window Systemskipx # Installation logging levellogging -- level = info # Reboot after installationreboot # System timezonetimezone -- isUtc Asia/Shanghai # Network informationnetwork -- bootproto = dhcp -- device = eth0 -- onboot = on # System bootloader configurationbootloader -- location = mbr # Clear the Master Boot Recordzerombr # Partition clearing informationclearpart -- all -- initlabel # Disk partitioning informationpart/boot -- fstype = "ext4" -- size = 200 part swap -- fstype = "swap" -- size = 1024 part/-- fstype = "ext4" -- grow -- size = 1

# This is the ks file generated on the GUI by installing system-config-kickstart.
# Do I see a Chinese character in the comment line of the first line? This is the Chinese character that left me stuck for two days... (do not include Chinese characters in the file)

5. Associate ks files

shell > cobbler distro listCentos-6.6-minimal-x86_64
