cobbler--centos7.3

Posted 2020-11-19 sky

centos7.3来做cobbler

第一步:

先安装cobbler相关软件包　　--这一次直接使用我们准备好的公网yum源安装就可以了

# yum install cobbler cobbler-web　tftp* rsync xinetd http* syslinux dhcp* pykickstart　fence-agents xinetd debmirror system-config-kickstart

第二步:

再把上面准备好的这台机器换成虚拟机的私有网络，我这里仍然是使用昨天使用的vmnet1网络和192.168.1.2/24这个IP

cobbler server ------- client

192.168.1.2/24

修改虚拟机的网卡连接/dev/vmnet1网络

然后修改ip地址

# vim /etc/sysconfig/network-scripts/ifcfg-ens33 ----打开网卡配置文件，只修改ip和掩码，其它不变

......

IPADDR="192.168.1.2"

PREFIX="24"

......

# systemctl restart network.service

重启网络后，使用ifconfig查看验证一下是否获取到了192.168.1.2/24这个ip

第三步：启动服务，并使用cobbler check查询哪些需要修改

# systemctl start cobblerd.service

# systemctl start httpd.service

# cobbler check

第四步：按照cobbler check对应的信息修改

# sed -i 272s/127.0.0.1/192.168.1.2/ /etc/cobbler/settings

# sed -i 384s/127.0.0.1/192.168.1.2/ /etc/cobbler/settings

# sed -i 242s/0/1/ /etc/cobbler/settings

# openssl passwd -1 -salt \'xcvsfdsdfwq\' \'123456\'

$1$xcvsfdsd$cGxdcHuQGCnu5vJw5M7zX1

# vim /etc/cobbler/settings -----在101行把上面产生的密码字符串粘贴到""里替代原来的字符串

default_password_crypted: "$1$xcvsfdsd$cGxdcHuQGCnu5vJw5M7zX1"

# systemctl restart cobblerd.service

# sed -i /disable/s/yes/no/ /etc/xinetd.d/tftp

# systemctl start rsyncd.service

# systemctl enable rsyncd.service

第五步：导入centos7.3的iso镜像

# cobbler import --path=/yum/ --name=centos7.3

# cobbler distro list --导入成功后，确认导入的镜像名

centos7.3-x86_64

# cobbler profile list --导入成功后，确认默认的profile名

centos7.3-x86_64

第六步：修改dhcp配置模块

# vim /etc/cobbler/dhcp.template　　-----在此文件的第21行到第25行修改成你对应的网段和ip

subnet 192.168.1.0 netmask 255.255.255.0 {

option routers 192.168.1.2;

option domain-name-servers 192.168.1.2;

option subnet-mask 255.255.255.0;

range dynamic-bootp 192.168.1.100 192.168.1.254;

第七步：使用cobbler sync同步，并启动xinetd服务

# cobbler sync

# systemctl start xinetd.service

第八步：新建另一个虚拟机(保证相同私有网络,并且最好2G内存,内存小的话会在安装时报空间不够的错误)，进行安装测试　

第九步：使用system-config-kickstart图形自定义ks文件

# vim /etc/yum.repo.d/local.repo ----需要把软件仓库里改成development，图形才能选择包，否则图形在选择软件包那一步看不到

[development]

name=development

baseurl=file:///yum/

enabled=1

gpgcheck=0

# yum clean all

# system-config-kickstart -----图形自定义ks文件，过程省略

定义的ks.cfg文件：

#platform=x86, AMD64, or Intel EM64T

#version=DEVEL

# Install OS instead of upgrade

install

# Keyboard layouts

keyboard \'us\'

# Root password

rootpw --iscrypted $1$s.qimPg3$T/Wp3yfp7/CZfQLfYcT69.

# Use network installation

url --url="http://192.168.1.2/cobbler/ks_mirror/centos7.3/"

# System language

lang en_US

# Firewall configuration

firewall --disabled

# System authorization information

auth --useshadow --passalgo=sha512

# Use text mode install

text

firstboot --disable

# SELinux configuration

selinux --disabled

# Network information

network --bootproto=dhcp --device=eth0

# Reboot after installation

reboot

# System timezone

timezone Asia/Shanghai

# System bootloader configuration

bootloader --location=mbr

# Clear the Master Boot Record

zerombr

# Partition clearing information

clearpart --all --initlabel

# Disk partitioning information

part /boot --asprimary --fstype="xfs" --size=300

part swap --asprimary --fstype="swap" --size=2000

part / --asprimary --fstype="xfs" --grow --size=1

# cobbler profile list

my_profile1

最后进行安装测试
