CentOS7下部署Cobbler实现PXE+Kickstart自动化安装的操作步骤
1、使用腾讯软件源站点https://mirrors.cloud.tencent.com/
下载epel镜像源配置文件
wget -O /etc/yum.repos.d/epel.repo http://mirrors.cloud.tencent.com/repo/epel-7.repo
2、 yum install cobbler cobbler-web
3、安装cobbler会用到的一些组件包
yum install dhcp tftp-server pykickstart httpd rsync xinetd
4、启动cobblerd和httpd服务
systemctl start cobblerd.service systemctl start httpd.service
cobbler check检查配置
5、根据上面cobbler check检查配置给出的提示，一一进行配置
1)cd /etc/cobbler/ cp settings settings_default_bak
2)278行net_server:127.0.0.1改成192.168.31.200
390行server: 127.0.0.1改成192.168.31.200
3)vi /etc/xinetd.d/tftp
改disable=yes为disable= no
然后
systemctl enable xinetd systemctl enable tftp systemctl start xinetd systemctl start tftp
4)cobbler get-loaders
下载操作系统引导文件
5)启动rsyncd服务，并设为开机自启动
systemctl enable rsyncd systemctl start rsyncd
6)vi /etc/cobbler/dhcp.template
7)vi /etc/cobbler/settings
manage_dhcp: 0改为manage_dhcp: 1
8)重启服务，同步配置文件
systemctl restart cobblerd cobbler sync
9)cobbler check检查配置
10)openssl passwd -1 -salt 'root' 'admin@2020'
vi /etc/cobbler/settings
default_password_crypted: "$1$root$afc2RZysD6SOx07LLBnwB0"
这时再重启cobblerd服务
systemctl restart cobblerd
cobbler sync同步配置
cobbler check 这时只有一个无关紧要的提示项
6、配置基本完成后，挂载CentOS7.7.1908版本的官方ISO镜像包
7、导入镜像
1）cobbler import --path=/mnt/cdrom --name=CentOS_7.7.1908
2）cobbler list
3）systemctl restart cobblerd.service
cobbler sync
8、验证Web是否可以正常访问
http://192.168.31.200/cobbler/ks_mirror/
9、新建一台虚拟机，测试PXE安装
10、关于定制Kickstart实现一键安装的操作步骤
1)cd /var/lib/cobbler/kickstarts/ vi CentOS7.ks
关于ks文件可以参考之前的文章
CentOS系统下PXE服务器的搭建与部署
PXE+Kickstart实现无人值守自动化安装CentOS系统
CentOS6.9下制作一键安装的ISO系统镜像
kickstart配置文件如下，
#platform=x86, AMD64, or Intel EM64T #version=DEVEL # Install OS instead of upgrade install # Keyboard layouts keyboard 'us' # Root password rootpw --iscrypted $1$.V2f7Wsz$0EdykaW/HEQoy./Zs3Tfu. # System language lang en_US # System authorization information auth --useshadow --passalgo=sha512 # Use network installation url --url="http://192.168.31.200/cobbler/ks_mirror/CentOS_7.7.1908" # Use graphical install graphical # SELinux configuration selinux --disabled # Do not configure the X Window System skipx # Firewall configuration firewall --disabled # Network information network --bootproto=dhcp --device=ens33 --onboot=on # Reboot after installation reboot # System timezone timezone Asia/Shanghai --isUtc # System bootloader configuration bootloader --location=mbr # Clear the Master Boot Record zerombr # Partition clearing information clearpart --all --initlabel # Disk partitioning information part /boot --fstype=ext4 --asprimary --size=1024 part / --fstype=ext4 --asprimary --size=20480 part swap --asprimary --size=16384 part pv.008006 --grow --size=200 volgroup vg_centos --pesize=4096 pv.008006 logvol /opt --fstype=ext4 --name=lv_opt --vgname=vg_centos --grow --size=200 %packages @^infrastructure-server-environment @base @core @debugging @development @file-server @ftp-server @ha chrony kexec-tools %end
关于profile默认使用的ks是/var/lib/cobbler/kickstarts/sample_end.ks
使用cobbler profile edit 进行编辑
cobbler profile edit --name=CentOS_7.7.1908-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS7.ks
3)
mount -t iso9660 /CentOS_ISO/CentOS-7-x86_64-DVD-1908.iso /temp_cdrom/ cd /temp_cdrom/ cp -r * /mnt/cdrom/
4）先删除前面的cobbler profile 和distro
5)cobbler import --path=/mnt/cdrom --name=CentOS_7.7.1908
重新导入镜像并修改profile
6）重新启动cobblerd服务，并同步配置
systemctl restart cobblerd.service cobbler sync
7)测试一键PXE+Kickstart自动安装，如下图所示全程无需操作可以直接实现一键安装
本次实验实现过程参考如下文章完成
