cobbler批量安装客户端

xiaoxiao2025-04-13 21

关闭防火墙、selinux然后重启一下虚拟机

配置yum源

[root@server ~]# curl -o /etc/yum.repos.d/CentOS7-Base-163.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo [root@server ~]# sed -i 's/\$releasever/7/g' /etc/yum.repos.d/CentOS7-Base-163.repo [root@server ~]# sed -i 's/^enabled=.*/enabled=1/g' /etc/yum.repos.d/CentOS7-Base-163.repo [root@server ~]# yum -y install epel-release 安装过程略。。。

安装cobbler以及相关的软件

[root@server ~]# yum -y install httpd dhcp tftp python-ctypes cobbler xinetd cobbler-web pykickstart 安装过程略。。。

启动服务并设置开机自启

[root@server ~]# systemctl start httpd.service [root@server ~]# systemctl start cobblerd.service [root@server ~]# systemctl enable httpd Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service. [root@server ~]# systemctl enable cobblerd.service Created symlink from /etc/systemd/system/multi-user.target.wants/cobblerd.service to /usr/lib/systemd/system/cobblerd.service. //修改server的ip地址为本机ip [root@server ~]# sed -i 's/^server: 127.0.0.1/server: 192.168.102.11/' /etc/cobbler/settings //设置tftp的ip地址为本机ip [root@server ~]# sed -i 's/^next_server: 127.0.0.1/next_server: 192.168.102.11/' /etc/cobbler/settings //开启tftp [root@server ~]# sed -i '/disable/s/yes/no/g' /etc/xinetd.d/tftp

下载缺失文件

[root@server ~]# cobbler get-loaders task started: 2018-10-28_222319_get_loaders task started (id=Download Bootloader Content, time=Sun Oct 28 22:23:19 2018) downloading https://cobbler.github.io/loaders/README to /var/lib/cobbler/loaders/README downloading https://cobbler.github.io/loaders/COPYING.elilo to /var/lib/cobbler/loaders/COPYING.elilo downloading https://cobbler.github.io/loaders/COPYING.yaboot to /var/lib/cobbler/loaders/COPYING.yaboot downloading https://cobbler.github.io/loaders/COPYING.syslinux to /var/lib/cobbler/loaders/COPYING.syslinux downloading https://cobbler.github.io/loaders/elilo-3.8-ia64.efi to /var/lib/cobbler/loaders/elilo-ia64.efi downloading https://cobbler.github.io/loaders/yaboot-1.3.17 to /var/lib/cobbler/loaders/yaboot downloading https://cobbler.github.io/loaders/pxelinux.0-3.86 to /var/lib/cobbler/loaders/pxelinux.0 downloading https://cobbler.github.io/loaders/menu.c32-3.86 to /var/lib/cobbler/loaders/menu.c32 downloading https://cobbler.github.io/loaders/grub-0.97-x86.efi to /var/lib/cobbler/loaders/grub-x86.efi downloading https://cobbler.github.io/loaders/grub-0.97-x86_64.efi to /var/lib/cobbler/loaders/grub-x86_64.efi *** TASK COMPLETE *** //看到这一条就说明成功了此时可以在游览器上访问https://192.168.102.11/cobbler_web

启动rsync并设置开机自启

[root@server ~]# systemctl start rsyncd [root@server ~]# systemctl enable rsyncd Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.

生成加密的密码

[root@server ~]# openssl passwd -1 -salt "$RANDOM" 'wangqing123!' $1$16884$gNXHahIREtcHhmHVTxzGF. //这是密码加密后的形式

//将新生成的加密密码加入到配置文件

[root@server ~]# vim /etc/cobbler/settings 。。。 default_password_crypted: "$1$16884$gNXHahIREtcHhmHVTxzGF." 。。。

重启cobbler

[root@server ~]# systemctl restart cobblerd.service [root@server ~]# ss -antl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:22 *:* LISTEN 0 100 127.0.0.1:25 *:* LISTEN 0 5 127.0.0.1:25151 *:* LISTEN 0 5 *:873 *:* LISTEN 0 128 :::80 :::* LISTEN 0 128 :::22 :::* LISTEN 0 100 ::1:25 :::* LISTEN 0 128 :::443 :::* LISTEN 0 5 :::873 :::*

通过cobbler check核对当前设置是否有问题

[root@server ~]# cobbler check The following are potential configuration items that you may want to fix: 1 : debmirror package is not installed, it will be required to manage debian deployments and repositories 2 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them Restart cobblerd and then run 'cobbler sync' to apply changes. //以上两个是关于debian系统的错误，请忽略

配置cobbler dhcp

修改cobbler配置文件，让cobbler控制dhcp

登入：账号密码都为cobbler 设置manage_dhcp为1

配置dhcp

[root@server ~]# vim /etc/cobbler/dhcp.template subnet 192.168.102.0 netmask 255.255.255.0 { option routers 192.168.102.11; option domain-name-servers 192.168.102.11; option subnet-mask 255.255.255.0; range dynamic-bootp 192.168.102.100 192.168.102.120; default-lease-time 21600; max-lease-time 43200; next-server $next_server;

重启服务并同步配置，改完dhcp必须要sync同步配置

[root@server ~]# systemctl restart cobblerd [root@server ~]# cobbler sync task started: 2018-10-28_230822_sync task started (id=Sync, time=Sun Oct 28 23:08:22 2018) running pre-sync triggers cleaning trees removing: /var/lib/tftpboot/pxelinux.cfg/default removing: /var/lib/tftpboot/grub/images removing: /var/lib/tftpboot/grub/grub-x86.efi removing: /var/lib/tftpboot/grub/grub-x86_64.efi removing: /var/lib/tftpboot/grub/efidefault removing: /var/lib/tftpboot/s390x/profile_list copying bootloaders trying hardlink /var/lib/cobbler/loaders/grub-x86.efi -> /var/lib/tftpboot/grub/grub-x86.efi trying hardlink /var/lib/cobbler/loaders/grub-x86_64.efi -> /var/lib/tftpboot/grub/grub-x86_64.efi copying distros to tftpboot copying images generating PXE configuration files generating PXE menu structure rendering DHCP files generating /etc/dhcp/dhcpd.conf rendering TFTPD files generating /etc/xinetd.d/tftp cleaning link caches running post-sync triggers running python triggers from /var/lib/cobbler/triggers/sync/post/* running python trigger cobbler.modules.sync_post_restart_services running: dhcpd -t -q received on stdout: received on stderr: running: service dhcpd restart received on stdout: received on stderr: Redirecting to /bin/systemctl restart dhcpd.service running shell triggers from /var/lib/cobbler/triggers/sync/post/* running python triggers from /var/lib/cobbler/triggers/change/* running python trigger cobbler.modules.scm_track running shell triggers from /var/lib/cobbler/triggers/change/* *** TASK COMPLETE *** [root@server ~]# netstat -anulp | grep dhcp udp 0 0 0.0.0.0:67 0.0.0.0:* 3944/dhcpd

导入Redhat7镜像

导入需要一点时间

看到这说明导入完成了

创建kickstarts自动安装脚本上面添加的内容那个一长条字符串是你虚拟机的加密密码，在/root/下有一个anaconda-ks.cfg，将这里的改成这个文件里的字符串登录密码就跟虚拟机一样了

配置网卡名称为传统网卡名称eth0

检查当前系统cobbler配置文件信息

为避免发生未知问题，先把服务端所有服务重启
