自动化安装适用于IDC机房批量安装服务器；
现在我们的自动化安装的方法有两种；今天我们来实现一下Cobbler的配置；
1.PXE，这种配置起来比较麻烦；
2.Cobbler，这种批量安装的方法，也是基于PEX结构执行的，但是Cobbler省去了我们配置文件的步骤，都交给了Cobbler来完成；
1）安装软件；查看服务是否启动
[[email protected] ~]# yum install tftp-server rsync xinetd httpd dhcp [[email protected] ~]# systemctl enable xinetd [[email protected] ~]# systemctl enable tftp [[email protected] ~]# systemctl start xinetd [[email protected] ~]# yum install cobbler [[email protected] ~]# systemctl start cobblerd [[email protected] ~]# systemctl restart httpd
[[email protected] ~]# 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 featuresot 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.
3 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your S
https://github.com/cobbler/cobbler/wiki/Selinux
4 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/tftp
5 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run ‘cobbler get-loaders‘ to download sure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely.s, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The ‘cobbler get-loaders‘ command is the easiest way to
6 : enable and start rsyncd.service with systemctl
7 : debmirror package is not installed, it will be required to manage debian deployments and repositories
8 : ksvalidator was not found, install pykickstart
9 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/co"openssl passwd -1 -salt ‘random-phrase-here‘ ‘your-password-here‘" to generate new one
10 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fe
Restart cobblerd and then run ‘cobbler sync‘ to apply changes.
2）挂载光盘镜像
[[email protected] ~]# mount /dev/cdrom /mnt/ [[email protected] ~]# cobbler import --path=/mnt --name=CentOS_7
从上面显示信息所知，cobbler会将镜像中的内容拷贝到本地一份，放在/var/www/cobbler/ks_mirror下的CentOS_7目录下。同时会创建一个名字为CentOS_7-x86_64的一个发布版本
3)配置cobbler配置文件
首先修改cobbler配置，让cobbler来管理dhcp服务，编辑文件/etc/cobbler/settings [[email protected] ~]# vim /etc/cobbler/settings
4）修改cobbler中的dhcp配置文件；
[[email protected] ~]# systemctl restart cobblerd 同步cobbler配置
5）配置完成
[[email protected] ~]# cobbler sync
cobbler会自动进行初始化工作，移除已经存在的启动项，然后根据模板拷贝loader文件。之后再生成pxe的配置文件，生成dhcp的配置文件，最后再重启dhcp服务。接下来，就可以测试cobbler安装了。
6）配置安装文件，到这里我们自动安装就配置完成了，初始化密码为：cobbler
[[email protected] ~]# vim /var/lib/tftpboot/pxelinux.cfg/default
这个命令可以让我们自定义ks文件
[[email protected] ~]# cobbler profile edit --name=CentOS_7-x86_64 --distro=CentOS_7-x86_64 --kickstart=/var/lib/cobbler/kickstarts/sample_end.ks
Web页面配置
Web界面 web 界面的管理是一个非常简便的方法, 只需要安装cobbler_web 软件包即可 [[email protected] ~]# yum install cobbler-web [[email protected] ~]# systemctl restart cobblerd [[email protected] ~]# systemctl restart httpd 注意：地址是 https://192.168.88.101/cobbler
错误解决办法：
[[email protected] ~]# yum install python-pip [[email protected] ~]# pip install Django==1.8.9 [[email protected] ~]# systemctl restart httpd
