cobbler无人值守装机

2020-05-04 19:03:01  阅读：237  来源： 互联网

标签：x86 lib 64 7.7 装机 var cobbler 值守


工作原理

1、环境

cat /etc/redhat-release
uname -r
getenforce
systemctl status firewalld.service
hostname -I

2、部署Cobbler

一、安装相关依赖包

yum -y install httpd dhcp tftp python-ctypes cobbler  xinetd cobbler-web

二、启动相关服务

systemctl start httpd
systemctl start cobblerd
systemctl enable cobblerd
systemctl enable httpd

三、通过cobbler check 核对当前设置是否有问题

cobbler check

四、修改/etc/cobbler/settings配置文件

sed -i 's/^server: 127.0.0.1/server: 10.0.0.42/' /etc/cobbler/settings
sed -i 's/^next_server: 127.0.0.1/next_server: 10.0.0.42/' /etc/cobbler/settings
 vim /etc/xinetd.d/tftp

disable                 = no  # yes修改为no
cobbler get-loaders

五、添加rsync到自启动并启动rsync

systemctl enable rsyncd
systemctl start rsyncd

六、修改密码为123456 ，salt后面是常用的方式加密

[root@ c7-42 ~]# openssl passwd -1 -salt '123456' '123456'
$1$123456$wOSEtcyiP2N/IfIl15W6Z0
[root@ c7-42 ~]# vim /etc/cobbler/settings # 修改settings配置文件中下面位置，把新生成的密码加进去
default_password_crypted: "$1$123456$wOSEtcyiP2N/IfIl15W6Z0"

再次执行cobbler check

[root@ c7-42 ~]# cobbler check

七、配置cobbler-DHCP

[root@ c7-42 ~]# vim /etc/cobbler/settings
manage_dhcp: 1

修改dhcp.templates配置文件

subnet 10.0.0.0 netmask 255.255.255.0 { 
     option routers             10.0.0.42; #本机ip
     option domain-name-servers 10.0.0.42; #本机ip
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        10.0.0.100 10.0.0.254; #新建的虚拟机ip范围
     default-lease-time         21600;
     max-lease-time             43200;

重启服务并同步配置，改完dhcp必须要sync同步配置

[root@ c7-42 ~]# systemctl restart cobblerd.service
[root@ c7-42 ~]# cobbler sync

*** TASK COMPLETE ***

检查dhcp

[root@ c7-42 ~]# netstat -lnup|grep dhcp
udp        0      0 0.0.0.0:67              0.0.0.0:*                           3265/dhcpd

3、导入CentOs-7的镜像

一、挂载光盘镜像

[root@ c7-42 ~]# mount /dev/cdrom  /mnt
mount: /dev/sr0 is write-protected, mounting read-only

二、cobbler导入镜像

[root@ c7-42 ~]# cobbler import --path=/mnt --name=Centos-7.7 --arch=x86_64
task started: 2020-05-04_181209_import
task started (id=Media import, time=Mon May  4 18:12:09 2020)
Found a candidate signature: breed=redhat, version=rhel6
Found a candidate signature: breed=redhat, version=rhel7
Found a matching signature: breed=redhat, version=rhel7
Adding distros from path /var/www/cobbler/ks_mirror/Centos-7.7-x86_64:
creating new distro: Centos-7.7-x86_64
trying symlink: /var/www/cobbler/ks_mirror/Centos-7.7-x86_64 -> /var/www/cobbler/links/Centos-7.7-x86_64
creating new profile: Centos-7.7-x86_64
associating repos
checking for rsync repo(s)
checking for rhn repo(s)
checking for yum repo(s)
starting descent into /var/www/cobbler/ks_mirror/Centos-7.7-x86_64 for Centos-7.7-x86_64
processing repo at : /var/www/cobbler/ks_mirror/Centos-7.7-x86_64
need to process repo/comps: /var/www/cobbler/ks_mirror/Centos-7.7-x86_64
looking for /var/www/cobbler/ks_mirror/Centos-7.7-x86_64/repodata/*comps*.xml
Keeping repodata as-is :/var/www/cobbler/ks_mirror/Centos-7.7-x86_64/repodata
*** TASK COMPLETE ***

# --path 镜像路径
# --name 为安装源定义一个名字
# --arch 指定安装源是32位、64位、ia64, 目前支持的选项有: x86│x86_64│ia64
# 安装源的唯一标示就是根据name参数来定义，本例导入成功后，安装源的唯一标示就是：CentOS-7.1-x86_64，如果重复，系统会提示导入失败

三、导入完镜像以后，那么就使查看下cobbler

[root@ c7-42 ~]# cobbler list
distros:
   Centos-7.7-x86_64

profiles:
   Centos-7.7-x86_64

systems:

repos:

images:

mgmtclasses:

packages:

files:

四、配置ks

[root@ c7-42 ~]# cd /var/lib/cobbler/kickstarts
[root@ c7-42 kickstarts]# cp sample_end.ks CentOS7.7-x86_64.ks
[root@ c7-42 kickstarts]# cobbler profile list
   Centos-7.7-x86_64
[root@ c7-42 kickstarts]# cobbler profile edit --name Centos-7.7-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS7.7-x86_64.ks
[root@ c7-42 kickstarts]# cobbler profile edit --name Centos-7.7-x86_64 --kopts='net.ifnames=0 biosdevname=0'
