关于操作系统安装方面的自动化，早前我们使用 RedHat 推出的 Kickstart 来批量安装操作系统，近年来 RedHat 又推出一个 Cobbler 。
Cobbler 使用 Python 开发，小巧轻便，能够完成系统安装、甚至一些服务的管理。（ 号称是补鞋匠都能学会的工具 ）
Cobbler 支持命令行管理、web 界面管理、还提供了 API 接口，以便二次开法。
## 关闭 SELinux 、iptables ！！！
一、支撑环境安装
shell > yum -y install epel-release ## 安装 epel 源
shell > yum -y install cobbler httpd rsync tftp-server xinetd dhcp pykickstart fence-agents
二、配置 Tftp 、Rsync
shell > vim /etc/xinetd.d/tftp
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no ## 原为 yes
per_source = 11
cps = 100 2
flags = IPv4
}
shell > vim /etc/xinetd.d/rsync
service rsync
{
disable = no ## 原为 yes
flags = IPv6
socket_type = stream
wait = no
user = root
server = /usr/bin/rsync
server_args = --daemon
log_on_failure += USERID
}
shell > vim /etc/httpd/conf
ServerName 127.0.0.1:80
## 这个东西大家都知道。
二、配置 Cobbler
shell > openssl passwd -1 -salt 'random-phrase-here' '123456'
$1$random-p$mzxQ/Sx848sXgvfwJCoZM0
## 生成 root 密码（ 此密码为新安装的客户机 root 密码 ）
shell > vim /etc/cobbler/settings
manage_dhcp: 1 ## 原为 0
manage_tftpd: 1
manage_rsync: 1 ## 原为 0
next_server: 192.168.214.10 ## 本机 IP
server: 192.168.214.10 ## 本机 IP
default_password_crypted: "$1$random-p$mzxQ/Sx848sXgvfwJCoZM0" ## 生成的 root 密码
三、配置 DHCP
shell > vim /etc/cobbler/dhcp.template ## 直接修改这个文件即可
subnet 192.168.214.0 netmask 255.255.255.0 {
option routers 192.168.214.2;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.214.100 192.168.214.120;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
## 只修改这个区域的 IP 为合适的 IP 即可
shell > chkconfig --add httpd
shell > chkconfig --add xinetd
shell > chkconfig --add dhcpd
shell > chkconfig --add cobblerd
shell > service httpd start
正在启动 httpd：
shell > service xinetd start
正在启动 xinetd： [确定]
shell > service dhcpd start
正在启动 dhcpd： [失败]
shell > service cobblerd start
Starting cobbler daemon: [确定]
shell > cobbler check ## 检查配置

shell > cobbler get-loaders （ 解决方法 ）
[shell > cobbler check ## 再次检查
The following are potential configuration items that you may want to fix:
1 : service dhcpd is not running
2 : debmirror package is not installed, it will be required to manage debian deployments and repositories
Restart cobblerd and then run 'cobbler sync' to apply changes.
## 1 ：提示 dhcpd 没有运行，先不管
## 2 ：提示 debmirror 没有安装。如果不是安装 debian 之类的系统，可以忽略此提示。
（如需安装，下载地址为：?query=debmirror）
