[root@crobbler-90111 ~]# cobbler check   #检测cobbler

 #修改主配置文件

[root@cobbler-90111 ~]# cp /etc/cobbler/settings /etc/cobbler/settings.back

#重启cobbler服务，再次检测cobbler服务

[root@crobbler-90111 ~]# systemctl restart cobblerd

[root@cobbler-90111 ~]# cobbler check

 

【配置DHCP】

[root@crobbler-90111 ~]# vim /etc/cobbler/dhcp.template

 [root@cobbler-90111 ~]#sed -i '/^subnet/s/192.168.1.0/10.15.90.0/' /etc/cobbler/dhcp.template

[root@cobbler-90111 ~]# sed -i '/domain-name-servers/s/192.168.1.1/144.144.144.144/' /etc/cobbler/dhcp.template
[root@cobbler-90111 ~]# sed -i '/dynamic-bootp/s/192.168.1.100 192.168.1.254/10.15.90.100 10.15.90.150/' /etc/cobbler/dhcp.template

 

#绑定dhcp，tftp以及rsyncd服务托管

[root@cobbler-90111 ~]# sed -i '/manage_dhcp:/s/0/1/' /etc/cobbler/settings

[root@cobbler-90111 ~]# sed -i '/manage_rsync:/s/0/1/' /etc/cobbler/settings

[root@cobbler-90111 ~] sed -i '/manage_tftpd:/s/0/1/' /etc/cobbler/settings

#检查三个服务时候托管

[root@cobbler-90111 ~]# sed -n -e '/manage_tftpd:/p' -e '/manage_dhcp:/p' -e '/manage_rsync:/p' /etc/cobbler/settings
manage_dhcp: 1
manage_tftpd: 1
manage_rsync: 1

root@cobbler-90111 ~]# systemctl restart cobblerd   #重启cobbler服务

[root@cobbler-90111 ~]# cobbler sync   #设置sync同步

 

[root@cobbler-90111 ~]# cat /etc/dhcp/dhcpd.conf   #重启cobbler服务之后，检查dhcp配置文件中的配置是否生成！

 [配置系统安装镜像]

[root@cobbler-90111 ~]# mkdir /mnt/centos7.6
[root@cobbler-90111 ~]# mount -o loop CentOS-7-x86_64-DVD-1810.iso /mnt/centos7.6/   #挂载cnetos7.6镜像
mount: /dev/loop0 is write-protected, mounting read-only

[root@cobbler-90111 ~]# cobbler import --path=/mnt/centos7.6 --name=Centos7.6-x86_64 --arch=x86_64   #导入centos镜像到cobbler服务中
