• Cobbler的使用(三)


    一、挂载并导入ISO镜像

    • 加载镜像
    shell> mount -t auto -o loop CentOS-6.9-x86_64-bin-DVD1.iso /mnt/
    
    • 导入ISO镜像
    # --path 镜像路径
    # --name 为安装源定义一个名字
    # --arch 指定安装源是32位或64位,目前支持的选项有:x86 | x86_64 | ia64
    # 安装源的唯一标识就是根据name参数来定义的,本例导入成功后,标识就是CentOS-6.9-x86_64,如果重复,系统会提示导入失败。
    shell> cobbler import --path=/mnt/ --name=CentOS-6.9-x86_64 --arch=x86_64
    

    二、配置ks.cfg

    • 查看安装镜像文件信息
    # 在第一次导入系统镜像后,cobbler会给镜像指定一个默认的kickstart自动安装文件在 /var/lib/cobbler/kickstarts下的sample_end.ks
    shell> cobbler profile report --name=CentOS-6.9-x86_64
    Name : CentOS-6.9-x86_64
    TFTP Boot Files : {}
    Comment : 
    DHCP Tag : default
    Distribution : CentOS-6.9-x86_64
    Enable gPXE? : 0
    Enable PXE Menu? : 1
    Fetchable Files : {}
    Kernel Options : {}
    Kernel Options (Post Install) : {}
    Kickstart : /var/lib/cobbler/kickstarts/sample_end.ks
    
    • 创建ks.cfg文件(节选)
    shell> cat CentOS-6.9-x86_64.ks
    unsupported_hardware
    install
    text
    url --url=$tree
    lang en_US.UTF-8
    keyboard us
    skipx
    network --device em1 --bootproto dhcp --noipv6 --onboot=no --hostname 91donkeyOS
    rootpw --iscrypted $default_password_crypted
    firewall --disable
    authconfig --enableshadow --enablemd5
    selinux --disabled
    timezone --utc Asia/Shanghai
    firstboot --disable
    %include /tmp/fdisk
    reboot
    
    %post
    /bin/mv -fv /etc/udev/rules.d/70-persistent-net.rules /etc/sysconfig/network-scripts/ifcfg-em* /etc/sysconfig/network-scripts/ifcfg-p* /tmp/
    /bin/cp -fv /boot/grub/grub.conf /tmp/
    
    i=0
    for IfCard in `find /tmp/ -type f -name "ifcfg-*" | sort`
    do
        sed "s/DEVICE=.*/DEVICE=eth${i}/g" $IfCard > /etc/sysconfig/network-scripts/ifcfg-eth${i} # device=ethX
        sed -ci 's/ONBOOT=no/ONBOOT=yes/g' /etc/sysconfig/network-scripts/ifcfg-eth* # onboot=yes
        #sed -i 's/(BOOTPROTO=).*/1static/g' /etc/sysconfig/network-scripts/ifcfg-eth* # bootproto=static
        sed -ci 's/(BOOTPROTO=).*/1dhcp/g' /etc/sysconfig/network-scripts/ifcfg-eth* # bootproto=dhcp 
        echo "ARPCHECK=no" >> /etc/sysconfig/network-scripts/ifcfg-eth${i}
        i=`echo $(($i+1))`
    done
    
    # disable grub:rhgb
    sed -ci 's/rhgb//' /etc/grub.conf
    
    # disable ipv6
    cat << EOF >> /etc/modprobe.d/dist.conf
    options ipv6 disable=1
    EOF
    
    cat << EOF >> /etc/sysconfig/network
    NETWORKING_IPV6=off
    EOF
    
    
    • 编辑profile,修改关联的ks文件
    shell> cobbler profile edit --name=CentOS-6.9-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS-6.9-x86_64.ks
    
    • 再次查看安装镜像文件信息,kickstart的配置cfg文件地址被改变了。
    shell> cobbler profile report --name=CentOS-6.9-x86_64
    Name : CentOS-6.9-x86_64
    TFTP Boot Files : {}
    Comment : 
    DHCP Tag : default
    Distribution : CentOS-6.9-x86_64
    Enable gPXE? : 0
    Enable PXE Menu? : 1
    Fetchable Files : {}
    Kernel Options : {}
    Kernel Options (Post Install) : {}
    Kickstart : /var/lib/cobbler/kickstarts/CentOS-6.9-x86_64.ks
    
    • 同步cobbler数据,每次修改完都要镜像同步
    shell> cobbler sync
