新建一个虚拟机查看日志
下面是内存不给2G 的报错信息
yum install wireshark -y
tshark -ni eth1
也可把抓到的数据包写到文件中，然后放到windows中，使用wireshark打开
tshark -ni eth1 -w kickstart.pcap
安装
yum -y install tftp-server
启动
systemctl start tftp.socket
逐步观看，逐步处理
问题1：
处理方法：
上面报错是在TFTP服务的根目录找不到启动文件
pxelinux.0
[root@kickstart ~]# cd /var/lib/tftpboot/ # TFTP服务的根目录
[root@kickstart tftpboot]# ls
[root@kickstart tftpboot]#
yum -y install syslinux
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/问题2：
首先排除最简单故障原因：selinux是否关闭，防火墙是否关闭
查看tftp服务器日志/var/log/messages
处理方法：
上面的错误是因为pxelinux.0这个小系统的配置文件（default）不存在，或者文件名不对
如何找到这个配置文件
第一步：挂载镜像
mkdir -p /var/www/html/CentOS7
mount /dev/cdrom /var/www/html/CentOS7
第二步：从镜像中找到相关的配置文件
cp -a /var/www/html/CentOS7/isolinux/* /var/lib/tftpboot/
mkdir -p /var/lib/tftpboot/pxelinux.cfg
cp /var/www/html/CentOS7/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
配置完成

作用1：提供自动应答文件下载
作用2：提供安装系统所需的所有rpm包下载
yum -y install httpd
systemctl start httpd.service
检查步骤
http://10.0.0.201/CentOS7/
curl http://172.16.1.201/CentOS7/
方法1：新装CentOS系统/root/anaconda-ks.cfg
方法2：图形CentOS系统提供的图形工具
方法3：了解ks文件语法，编写ks文件。（推荐）
官网参考https://access.redhat.com/documentation/zh-cn/red_hat_enterprise_linux/7/html/installation_guide/chap-kickstart-installations1.1 ks文件组成
命令段
包组段 以%packages开头，以%end结束
脚本段 以%post开头，以%end结束，在安装完系统之后执行的相关Linux命令、脚本
以%pre开头，以%end结束，在安装完系统之前执行的相关Linux命令、脚本
1.2 kickstart文件语法检查
yum install pykickstart
ksvalidator /var/www/html/ks_config/CentOS-7-ks.cfg
请记住这个验证工具有其局限性。Kickstart 文件可能会很复杂；ksvalidator 可保证其语法正确，且该文件不包含淘汰的选项，但它无法保证安装会成功。它也不会尝试验证 Kickstart 文件的 %pre、%post 和 %packages 部分。

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 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/tftp
4 : 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.
5 : enable and start rsyncd.service with systemctl
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
7 : 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
8 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

找到下面
https://github.com/cobbler/cobbler/issues/1717
原因是本地dango版本为1.11，上面的依赖包在django1.10就被移除了。所以找不到次依赖包，暂时就降低django版本
#下载pip.py
wget https://bootstrap.pypa.io/get-pip.py
#调用本地python运行pip.py脚本
python get-pip.py
#安装django
会移除现有版本，安装指定版本
pip install Django==1.8.9
#查看版本
python -c "import django; print(django.get_version())"
#重启httpd
systemctl restart httpd
