centos7 cobbler安装

devil20

　　系统：

[iyunv@cobbler ~]# more /etc/redhat-release

　　CentOS Linux>　　一、安装基础软件：
　　 yum -y install wget net-tools curl epel-release
　　更新：
　　 yum -y update
　　 关闭iptables与selinux:
　　 [iyunv@cobbler ~]# vim /etc/selinux/config
　　 SELINUX=disabled
　　重启后查看：
　　 [iyunv@cobbler ~]# sestatus
　　 SELinux status:                 disabled
　　二、安装基础服务：
　　  yum -y install dhcp httpd xinetd tftp-server rsync fence-agents pykickstart
　　设置开机启动
　　  systemctl enable xinetd dhcpd httpd rsyncd
　　  systemctl start xinetd dhcpd httpd rsyncd
　　1、安装cobbler
　　  [iyunv@cobbler ~]# yum -y install cobbler-web
　　设置开机启动：
　　  systemctl enable cobblerd
　　  systemctl start cobblerd
　　2、效验cobbler安装条件
　　  [iyunv@cobbler ~]# cobbler check
　　  The following are potential configuration items that you may want to fix:
　　  1 : comment out 'dists' on /etc/debmirror.conf for proper debian support
　　  2 : comment out 'arches' on /etc/debmirror.conf for proper debian support
　　  Restart cobblerd and then run 'cobbler sync' to apply changes
　　3、随机生成一个密码
　　  [iyunv@cobbler ~]# openssl passwd -1 -salt "cobbler" "huangzai"
　　  $1$cobbler$zPOuqy9SLOb87DIQb3RbQ.
　　4、更改cobbler配置文件

[iyunv@cobbler ~]# vim /etc/cobbler/settings

　　·····
　　default_password_crypted: "$1$cobbler$zPOuqy9SLOb87DIQb3RbQ."   #第三步生成的密码
　　manage_dhcp: 1       #dhcp服务
　　manage_tftpd: 1        #xinetd服务
　　manage_rsync: 1       #rsyncd服务
　　next_server: 192.168.3.222    #替换成本机IP地址，dhcp服务地址
　　server: 192.168.3.222             #替换为本机IP地址，cobber服务地址
　　······
　　5、更新load信息：

[iyunv@cobbler ~]# cobbler get-loaders

　　task started: 2018-03-06_051434_get_loaders
　　task started (id=Download Bootloader Content, time=Tue Mar  6 05:14:34 2018)

　　6、设置tftp配置文件，‘disable'为'no'

[iyunv@cobbler ~]# cat /etc/xinetd.d/tftp | grep -v '^#'

service tftp
{
        disable                 = no
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -B 1380 -v -s /var/lib/tftpboot
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}　　7、修改dhcp配置文件

[iyunv@cobbler ~]# vim /etc/cobbler/dhcp.template

ddns-update-style interim;
allow booting;
allow bootp;
ignore client-updates;
set vendorclass = option vendor-class-identifier;
option pxe-system-type code 93 = unsigned integer 16;
subnet 192.168.3.0 netmask 255.255.255.0 {
     option routers             192.168.3.222;
     option domain-name-servers 202.96.209.5,202.96.209.133;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.3.60 192.168.3.100;
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                $next_server;
    >　　三、导入镜像进行配置
　　1、上传iso镜像到服务器
　　2、创建文件夹
　　  mkdir -p /data/centos7.0
　　3、将镜像文件挂载或copy到文件夹
　　  [iyunv@cobbler ~]# mount /dev/cdrom /data/centos7.0/
　　4、把挂载光盘镜像的mnt目录中的内容导入到cobbler

[iyunv@cobbler ~]# cobbler import --path=/data/centos7.0/ --name=cent7.0

　　task started: 2018-03-06_055628_import
