就是通过网络 安装linux
首先简单介绍一下Centos7的一些功能
systemctl 启动，重启，暂停服务,还可以设置开机自启动
systemctl enable httpd.service 开启自启动
systemctl start httpd service 启动服务
防火墙变成了 firewalld
关闭防火墙 systemctl disable firewalld
====================================
开始安装cobbler
yum install cobbler cobbler-web dhcp tftp-server pykickstart httpd -y
如果报错Django>=1.4 下载django，安装
http://cbs.centos.org/koji/buildinfo?buildID=1027
安装好后，清除yum缓存，yum clean all
启动
/etc/init.d/httpd start
/etc/init.d/cobblerd start
查看cobbler
cobbler check
#如果出现一堆错误，就重新启动一下bobbler
出现下面这样，然后一条一条解决
#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 : 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.
4 : change 'disable' to 'no' in /etc/xinetd.d/rsync
5 : debmirror package is not installed, it will be required to manage debian deployments and repositories
6 : 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
7 : 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.
解决：
第1,2问题
vim /etc/cobbler/settings
#pxe的位置
next_server: 10.0.0.123
server: 10.0.0.123
#管理dhcp，启动
manage_dhcp: 1
第3问题
执行
cobbler get-loaders
第4问题
disable = no
vim /etc/xinetd.d/rsync
重启/etc/init.d/xinetd restart
第6问题
#修改密码
openssl passwd -1 -salt '12345' '12345' $1$12345$4Gam1JX4790weMm6hLf9I/ 复制到 vim /etc/cobbler/settings default_password_crypted: "$1$12345$4Gam1JX4790weMm6hLf9I/"
重启
etc/init.d/cobblerd restart
Stopping cobbler daemon: [确定]
Starting cobbler daemon: [确定]
测试

剩下的可以不解决
yum install -y debmirror yum-utils fence-agents #装不装都行
#修改cobbler 下面的dhcp
vim /etc/cobbler/dhcp.template subnet 10.0.0.0 netmask 255.255.255.0 { option routers 10.0.0.2; #网关 option domain-name-servers 8.8.8.8; #dns option subnet-mask 255.255.255.0; range dynamic-bootp 10.0.0.100 10.0.0.200;#ip段 default-lease-time 21600; max-lease-time 43200; next-server $next_server; class "pxeclients" {
执行
cobbler sync
