  • 基于Centos7.2搭建Cobbler自动化批量部署操作系统服务

    1       Cobbler服务器端系统环境配置

    1.1     系统基本环境准备

    [root@cobbler-server ~]# cat /etc/redhat-release 
    CentOS Linux release 7.2.1511 (Core) 
    [root@cobbler-server ~]# uname -r
    3.10.0-327.el7.x86_64
    [root@cobbler-server ~]# getenforce
    Disabled
    [root@cobbler-server ~]# hostname
    cobbler-server
    [root@cobbler-server ~]# python -V
    Python 2.7.5
    [root@cobbler-server ~]# firewall-cmd --state
    not running 
    [root@cobbler-server ~]# ifconfig eth0 | awk -F " " 'NR==2{print $2}'
    172.16.0.2
    [root@cobbler-server ~]# echo "172.16.0.2 cobbler-server" >> /etc/hosts
    [root@cobbler-server ~]# ping cobbler-server
    PING cobbler-server (172.16.0.2) 56(84) bytes of data.
    64 bytes from cobbler-server (172.16.0.2): icmp_seq=1 ttl=64 time=0.058 ms
    64 bytes from cobbler-server (172.16.0.2): icmp_seq=2 ttl=64 time=0.059 ms

    1.1     安装配置阿里云epel源

    [root@cobbler-server ~]# rpm -Uvh https://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
    Retrieving https://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm

    [root@cobbler-server ~]# ls -lh /etc/yum.repos.d/epel*
    -rw-r--r-- 1 root root  951 Oct  3  2017 /etc/yum.repos.d/epel.repo

    [root@cobbler-server ~]# yum clean all
    [root@cobbler-server ~]# yum makecache

     注意:我们选择Vmware Workstation虚拟机演示,故需要关闭NAT模式下的DHCP服务

    2       Cobbler服务部署配置

    2.1     安装Cobbler组件服务

    [root@cobbler-server ~]# yum -y install cobbler cobbler-web dhcp tftp-server pykickstart httpd

    2.3     启动cobblerd、httpd服务并加入到开机启动

    [root@cobbler-server ~]# systemctl start cobblerd
    [root@cobbler-server ~]# systemctl enable cobblerd
    Created symlink from /etc/systemd/system/multi-user.target.wants/cobblerd.service to /usr/lib/systemd/system/cobblerd.service.
    [root@cobbler-server ~]# systemctl start httpd
    [root@cobbler-server ~]# systemctl enable httpd
    Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

    2.4     检查cobbler配置

    [root@cobbler-server ~]# 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 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 : 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.
    4 : enable and start rsyncd.service with systemctl
    5 : debmirror package is not installed, it will be required to manage debian deployments and repositories
    6 : 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
    7 : 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.
