  • cobbler自动安装系统(Centos7.X)

    环境:

    [root@kickstart ~]# cat /etc/redhat-release
    CentOS Linux release 7.4.1708 (Core)
    [root@kickstart ~]# uname -r
    3.10.0-693.el7.x86_64
    [root@kickstart ~]# getenforce
    Disabled
    [root@kickstart ~]# systemctl status  firewalld.service
    ● firewalld.service - firewalld - dynamic firewall daemon
       Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
       Active: inactive (dead)
         Docs: man:firewalld(1)
    [root@kickstart ~]# hostname -I
    10.0.0.201 172.16.1.201

    前言

    cobbler安装比较简单,主要是网页操作,点点点,相对于PXE+kickstart网络安装更简单。

    如果大家不了解PXE+kickstart网络安装系统过程原理的话,建议大家去看看我写的 <PXE+kickstart网络安装CentOS7.4系统及过程中各种报错>   <-- 快戳我

    cobbler安装

    1、下载cobbler及相关软件

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

    2、检查更改配置

    注意:CentOS7上需要启动httpd服务和cobbler服务才能检查

    [root@Cobbler ~]# systemctl start cobblerd.service httpd.service
    [root@Cobbler ~]# 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 : change 'disable' to 'no' in /etc/xinetd.d/tftp
    4 : 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.
    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.

    根据这些检查条目,进行更改相关的检查项

    sed -i 's/server: 127.0.0.1/server: 172.16.1.202/' /etc/cobbler/settings
    sed -i 's/next_server: 127.0.0.1/next_server: 172.16.1.202/' /etc/cobbler/settings
    sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings
    sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings
    sed -ri "/default_password_crypted/s#(.*: ).*#1"`openssl passwd -1 -salt 'oldboy' '123456'`"#" /etc/cobbler/settings
    sed -i 's#yes#no#' /etc/xinetd.d/tftp
    
    systemctl start rsyncd
    systemctl enable rsyncd
    systemctl enable tftp.socket
    systemctl start tftp.socket 
    systemctl restart cobblerd.service

    修改dhcp模板配置文件

    sed -i.ori 's#192.168.1#172.16.1#g;22d;23d' /etc/cobbler/dhcp.template

    同步所有配置

    注意:不同步会报错

    cobbler使用操作

    博主使用虚拟机操作

    https://10.0.0.202/cobbler_web    浏览器访问网址
    账号密码默认均为cobbler

    导入镜像(import DVD)

     说明:首先虚拟机保证下列以操作

     

    根据镜像位置,进行挂载

    因为镜像位置写的mnt,所以要将镜像挂载到mnt下
    [root@Cobbler pxelinux.cfg]# mount /dev/cdrom /mnt/
    [root@Cobbler pxelinux.cfg]# df -h
    Filesystem      Size  Used Avail Use% Mounted on
    /dev/sda3        98G  5.8G   93G   6% /
    devtmpfs        902M     0  902M   0% /dev
    tmpfs           912M     0  912M   0% /dev/shm
    tmpfs           912M  8.7M  903M   1% /run
    tmpfs           912M     0  912M   0% /sys/fs/cgroup
    /dev/sda1      1014M  135M  880M  14% /boot
    tmpfs           183M     0  183M   0% /run/user/0
    /dev/sr0        4.3G  4.3G     0 100% /mnt
    查看进程,看是否在导入
    [root@Cobbler ~]# ps -ef|grep rsync
    root    15923      1  0 09:49 ?    00:00:00 /usr/bin/rsync --daemon --no-detach
    root    17237  15973 15 10:53 ?    00:00:03 rsync -a /mnt/ /var/www/cobbler/ks_mirror/CentOS7.4-x86_64 --progress
    root    17238  17237  0 10:53 ?    00:00:00 rsync -a /mnt/ /var/www/cobbler/ks_mirror/CentOS7.4-x86_64 --progress
    root    17239  17238 11 10:53 ?    00:00:02 rsync -a /mnt/ /var/www/cobbler/ks_mirror/CentOS7.4-x86_64 --progress

     ks文件组成

    命令段

        install开头,到%pre

    包组段

        以%packages开头,以%end结束

    脚本段

        以%post开头,以%end结束,在安装完系统之后执行的相关Linux命令、脚本

        以%pre开头,以%end结束,在安装完系统之前执行的相关Linux命令、脚本

    kickstart文件语法检查

    下载语法检查软件

    yum install pykickstart -y

    检查命令

    [root@CentOS7 tftpboot]# ksvalidator /var/www/html/ks_config/CentOS-7-ks.cfg 
    说明:请记住这个验证工具有其局限性。Kickstart 文件可能会很复杂;ksvalidator 可保证其语法正确,且该文件不包含淘汰的选项,但它无法保证安装会成功。它也不会尝试验证 Kickstart 文件的 %pre、%post 和 %packages 部分。

    root加密密码生成

    密码:123456

    [root@CentOS7 ~]# python -c 'import crypt; print(crypt.crypt("123456"))'
    $6$02PfimLMqN53z6Io$ov2Xbjm7ZC36X2tFvqnI0HymvqMY0vI/UOCxze0L/zMX722PkDJOz/JTWwVHaksawGf/bfR0k3GCpubodKTdV0

    CentOS7的ks文件添加
