标签:cobbler自动装机centos7   cobbler web登录   在CentOS7中 部署cobbler   

Cobbler是一个Linux安装服务器,它允许快速安装网络安装环境。它聚合并自动化了许多相关的Linux任务,因此在部署新系统时,不必在许多不同的命令和应用程序之间跳跃,在某些情况下,还需要更改现有的系统。Cobbler可以帮助配置、管理DNS和DHCP、包更新、电源管理、配置管理业务流程等等。

 实验需要的安装包:
    cobbler(linux安装服务器)     
    cobbler-web(前端界面管理  可以通过网页形式进行管理)   dhcp(自动分配IP)  
    tftp-server (文件传输协议    用于放压缩内核和引导文件)
    pykickstart(用于阅读和编写kickstart文件)  
     rsync(数据镜像备份工具,远程同步管理和支持本地复制)  
    xinetd(网络守护进程服务程序   用于管理rsync 和 tftp)
    httpd  (这里用于检查cobbler文件安装 和web管理)

.

实验的系统环境
 虚拟机:centos7系统  (网卡选用NET模式   选定dhcp     可以实现访问网络)
 # vim /etc/sysconfig/network-scripts/ifcfg-ens33  //编辑网卡
        ONBOOT=yes   (修改成yes)
    # systemctl restart network.service  //重启网络服务

    # mount.cifs //192.168.198.128/gx /opt/   //挂载共享文件到/opt
    # rpm -ivh /opt/epel-release-latest-7.noarch.rpm  //安装epel-release-latest-7.noarch.rpm
    # mount /dev/sr0 /mnt  //挂载cdrom
    # yum list   //加载yum  (直接下载安装包)

.

1:安装  配置cobber
# yum install cobbler cobbler-web dhcp tftp-server pykickstart httpd rsync xinetd -y
//安装cobbler cobbler-web dhcp tftp-server pykickstart httpd rsync xinetd
#vim /etc/cobbler/settings  //编辑cobbler主配置文件
    next_server: 192.168.235.129          //指定PXE位置
    server: 192.168.235.129
    manage_dhcp: 1                 //管理dhcp启动

2:重启服务关闭防火墙
    # systemctl restart httpd.service        //重启httpd服务
    # systemctl start cobblerd.service     //开启cobbler服务
    # systemctl stop firewalld.service      //关闭防火墙
    # setenforce 0                          //关闭增强安全功能
    # cobbler check    //cobble 检测
------------------------提示内容:需要优化-------------------------- 
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 : 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
4 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/tftp
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
Restart cobblerd and then run ‘cobbler sync‘ to apply changes.

.

    3:设置装机后的根密码
     # openssl passwd -1 -salt ‘123456‘ ‘123456‘    //给密码123456 盐值加密
     $1$123456$wOSEtcyiP2N/IfIl15W6Z0   (复制生成的密码的加密代码)
     # vim /etc/cobbler/settings       //修改配置文件
     default_password_crypted: " $1$123456$wOSEtcyiP2N/IfIl15W6Z0 ."    //粘贴上面复制代码

     4:下载引导操作系统文件、 启动rsncd服务 、编辑tftp 
         # cobbler get-loaders                //下载引导操作系统文件
         # systemctl start rsyncd.service      //启动服务
         #  vim /etc/xinetd.d/tftp          //编辑tftp
                 disable   = no     //启用
         # systemctl restart xinetd.service      //重启服务

         5:配置dhcp
         # vim /etc/cobbler/dhcp.template       //cobbler控制的dhcp服务模板
                 subnet 192.168.198.0 netmask 255.255.255.0 {
                 option routers             192.168.198.1;     //修改网关
                 option domain-name-servers 192.168.198.2;     //修改DNS
                 option subnet-mask         255.255.255.0;
                 range dynamic-bootp        192.168.198.100 192.168.198.200;   //修改地址池
            # cobbler sync       //帮助同步生成DHCP配置文件
            # systemctl restart dhcpd.service    //启动dhcpd服务

        6:使用cobbler check再次检查
         # cobbler check //cobble 检测
         下面三条可以忽略不去处理

            7:导入镜像
            # cobbler import --path=/mnt/ --name=CentOS-7-x86_64 --arch=x86_64  //导入iso镜像
            # cobbler list     //查看导入结果
            # cobbler distro list   //查看发行版本
            # yum install tree -y //安装tree
            # tree /var/lib/tftpboot/images   //查看内核和初始化文件在tftp server 共享目录

            8:服务全重启一遍
                    # systemctl restart cobblerd.service
                    # systemctl restart dhcpd.service
                    # systemctl restart xinetd.service
                    # systemctl restart httpd.service
                    # cobbler profile report         //查看cobbler概要报告      

.

            9:新建虚拟机测试安装
            选择稍后安装
            虚拟机为centos 64位       
            网络选择和服务器一样的NAT网卡 
            内存2G   硬盘40G
            然后开启虚拟机 进入安装
