cobbler自动化安装操作系统

1 安装cobbler等依赖服务

yum install -y epel-release
yum install cobbler cobbler-web dhcp tftp-server pykickstart httpd rsync xinetd net-tools -y

2. 启动httpd和cobbler服务，并开机自启

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

**3. **firewall和selinux关闭并且重启系统

systemctl stop firewalld && systemctl disable firewalld
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/sysconfig/selinux
reboot

进行check

cobbler check
The following are potential configuration items that you may want to fix:

1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work.  This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
3 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
    https://github.com/cobbler/cobbler/wiki/Selinux
4 : change 'disable' to 'no' in /etc/xinetd.d/tftp
5 : Some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely.  Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.
6 : enable and start rsyncd.service with systemctl
7 : debmirror package is not installed, it will be required to manage debian deployments and repositories
8 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one
9 : 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.

5.修改/etc/cobbler/settings文件

1 vi /etc/cobbler/settings 
#将272行改为 next_server: 192.168.134.132（你的ip地址）
#将384行改为 server: 192.168.134.132
2vim /etc/xinetd.d/tftp
 #将disable改为no
  systemctl start tftp xinetd.service && systemctl enable tftp xinetd.service
3 cobbler get-loaders
4 systemctl start rsyncd && systemctl enable rsyncd

cobbler get-loaders显示以下log

6.使用openssl对密码加密

1 openssl passwd -1 -salt 'root' '123456' #前面的root为掩码，后面的为密码，可随意设置.
  $1$root$j0bp.KLPyr.u9kgQ428D10
2 vi /etc/cobbler/settings #将刚才的密码替换文档中101中的密码，然后修改242行，将manage_dncp改为1

7.修改/etc/cobbler/dhcp.template，执行cobbler sync

vi /etc/cobbler/dhcp.template
subnet 192.168.3.0 netmask 255.255.255.0 {   ------地址段
     option routers             192.168.3.1;  ------网关

     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.3.200 192.168.3.210; -------分配范围
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                $next_server;
     class "pxeclients" {
          match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
          if option pxe-system-type = 00:02 {
                  filename "ia64/elilo.efi";
          } else if option pxe-system-type = 00:06 {
                  filename "grub/grub-x86.efi";
          } else if option pxe-system-type = 00:07 {
                  filename "grub/grub-x86_64.efi";
          } else if option pxe-system-type = 00:09 {
                  filename "grub/grub-x86_64.efi";
          } else {
                  filename "pxelinux.0";
          }
     }

}

重启服务

systemctl restart cobblerd
