cobbler安装、部署、测试

cobbler功能介绍

官网：http://cobbler.github.io

安装

yum install -y httpd tftp dhcp cobbler cobbler-web pykickstart xinetd
/etc/httpd/conf.d目录下存在cobbler的配置文件，如下图中cobbler.conf、cobbler_web.conf

启动apache

systemctl start httpd

查看开启服务

netstat -ntlp

启动cobbler

systemctl start cobblerd

检查cobbler

cobbler check

根据上图可以看到，使用cobbler需要完成的9个步骤。

修改 vim /etc/cobbler/settings

1) 找到next_server这行，将ip地址修改，next_server参数的值为提供PXE服务的主机相应的IP地址

2) 找到server这行，将ip地址修改，server参数的值为提供cobbler服务的主机相应的IP地址或主机名

3) 关闭并确认SELinux 处于关闭状态
vi /etc/sysconfig/selinux
SELINUX=disabled #修改为disabled

4) vim /etc/xinetd.d/tftp

将disable设置为no

5)执行 cobbler get-loaders 命令

6) 启动rsyncd服务

systemctl start rsyncd.service

7) openssl passwd -1 -salt 'cobbler' 'cobbler'

生成一串密码

vim /etc/cobbler/settings

将生成的密码写入default_password_crypted

8) yum -y install cman fence-agents

9) 重启systemctl restart cobblerd

配置DHCP

vim /etc/cobbler/settings

将manage_dhcp的值改成1

修改dhcp的模板文件

vim /etc/cobbler/dhcp.template

systemctl restart cobblerd

systemctl start xinetd

同步cobbler

cobbler sync

cat /etc/dhcp/dhcpd.conf

查看生成的dhcp配置文件

管理cobbler

mount /dev/cdrom /mnt/ #挂在ISO光盘至服务器

cobbler import --path=/mnt/ --name=CentOS-7.1-x86_64 --arch=x86_64 # 导入镜像文件

# --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

镜像存放目录，cobbler会将镜像中的所有安装文件拷贝到本地一份，放在/var/www/cobbler/ks_mirror下的CentOS-7.1-x86_64-distro-x86_64目录下。因此/var/www/cobbler目录必须具有足够容纳安装文件的空间。

管理profile

cobbler profile

cobbler profile list 查看导入的镜像文件

cobbler profile report 查看profile的内容

cobbler profile edit --name=CentOS-7.1-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS-7-x86_64.cfg

cobbler profile edit --name=CentOS-6.8-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS-6-x86_64.cfg

修改名称为CentOS-7.1-x86_64和CentOS-6.8-x86_64的自定义的kickstart文件
