　　部署校验
　　这货有一个自我检查的命令，可以知道在部署前还需要解决哪些问题
　　cobbler check

　　还有9个问题要处理，容我处理下
　　设置服务器IP
　　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.
　　vi /etc/cobbler/settings
　　cat /etc/cobbler/settings | grep -v ^# | grep -v ^$
　　改3个地方
　　bind_master: 192.168.10.10
　　next_server: 192.168.10.10
　　server: 192.168.10.10

　　禁用SELinux
　　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
　　systemctl stop firewalld
　　systemctl disable firewalld
　　sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
　　grep SELINUX=disabled /etc/selinux/config
　　setenforce 0
　　开启TFTP
　　change 'disable' to 'no' in /etc/xinetd.d/tftp
　　vi /etc/xinetd.d/tftp

　　开启rsync
　　enable and start rsyncd.service with systemctl
　　systemctl start rsyncd
　　systemctl enable rsyncd

　　安装fencing
　　fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
　　rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
　　yum install -y fence-agents

　　systemctl restart cobblerd
　　cobbler check
　　剩下4个问题

　　下载启动程序
　　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.
　　cobbler get-loaders

　　安装大便镜像package
　　debmirror package is not installed, it will be required to manage debian deployments and repositories
　　yum install -y debmirror.noarch

　　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
　　openssl passwd -1 -salt 'random-phrase-here' '12345.com'
　　$1$random-p$N2Gta7Jon4dskSI6zKe5C1
　　vi /etc/cobbler/settings
　　把default_password_crypted 替换成新密码

　　cobbler sync
　　cobbler check

　　还剩下2个问题
　　vi /etc/debmirror.conf
　　2行注释拿掉

　　应用配置文件
　　systemctl restart cobblerd
　　cobbler sync
　　cobbler check

　　all system go
　　开启dhcp和pxe
　　sed -i 's/manage_dhcp: 0/manage_dhcp: 1/g' /etc/cobbler/settings
　　cat /etc/cobbler/settings | grep manage_dhcp

　　sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings
　　cat /etc/cobbler/settings |grep pxe_just

　　设置dhcp ip 地址池
　　cp /etc/cobbler/dhcp.template /etc/cobbler/dhcp.template.original
　　vi /etc/cobbler/dhcp.template

　　systemctl restart dhcpd
　　systemctl enable dhcpd
　　挂载镜像

　　mount -t iso9660 -o ro /dev/cdrom /mnt

　　导入镜像
　　cobbler import --path=/mnt/ --name=CentOS-7.5-x86_64 --arch=x86_64

　　cobbler distro list

　　ls /var/www/cobbler/ks_mirror/

　　查看镜像文件信息
　　cobbler list
　　cobbler distro report --name=CentOS-7.5-x86_64

　　修改网卡配置，因为cenos 7之后网卡从eth0变成ens打头的了
　　cobbler profile report

　　cobbler profile edit --name=CentOS-7.5-x86_64 --kopts='net.ifnames=0 biosdevname=0'
　　cobbler profile report --name=CentOS-7.5-x86_64

　　同步下数据
　　cobbler sync

　　自定义pxe菜单
　　vi /etc/cobbler/pxe/pxedefault.template

　　眼睛一闭就好了

　　直接指定IP和MAC 绑定某一个安装菜单
　　cobbler system add --name=CentOS --mac=00:0C:29:D6:4F:57 --profile=CentOS-7.5-x86_64 --ip-address=192.168.10.100 --subnet=255.255.255.0 --gateway=192.168.10.2 --interface=eth0 --static=1 --hostname=linux_node --name-servers="8.8.8.8"
　　同步数据
　　cobbler system list
　　cobbler sync
　　问题 找不到boot，磁盘空间不足

　　容我修个错误
　　https://access.redhat.com/solutions/3353961
　　Root Cause

• The memory defined for the system is not sufficient hence it is unable to process/download the live image.
  
• Minimum of 2GB of memory should be allocated.
  

　　虚拟机给2G内存搞定
　　问题 禁止PXE
　　cobbler profile edit --name=CentOS-7.5-x86_64 --enable-gpxe=False
　　cobbler profile report --name=CentOS-7.5-x86_64

　　cat /etc/cobbler/modules.conf | grep -v ^$ | grep -v ^#
