  • Cobbler自动装机--2

     自动重装工具--koan


    客户机已经通过cobbler安装centos7系统完毕。

    安装koan,能实现重装,安装之前先安装epel源

    koan是kickstart-over-a-network的缩写,它是cobbler的客户端帮助程序,koan允许你通过网络提供虚拟机

    也允许你重装已经存在的客户端。当运行时,koan会从远端的cobbler server获取安装信息,然后根据获取的安装信息进行安装。

    cobbler-web


    火狐浏览器打开

    https://192.168.58.11/cobbler_web

    用户名密码默认cobbler

     

    用户和密码其实在配置文件中

    user.conf是用户文件   ,users.digest是密码文件

    [root@linux-node1 ~]# cd /etc/cobbler/
    [root@linux-node1 cobbler]# ls
    auth.conf               iso             reporting           users.digest
    cheetah_macros          ldap            rsync.exclude       version
    cobbler_bash            modules.conf    rsync.template      zone.template
    completions             mongodb.conf    secondary.template  zone_templates
    dhcp.template           named.template  settings
    dnsmasq.template        power           tftpd.template
    import_rsync_whitelist  pxe             users.conf
    [root@linux-node1 cobbler]# tail -5 users.conf 
    
    [admins]
    admin = ""
    cobbler = ""
    
    [root@linux-node1 cobbler]# cat users.digest 
    cobbler:Cobbler:a2d6bae81669d707b72c0bd9806e01f3
    [root@linux-node1 cobbler]# 
    

      

     更改cobbler密码为123123

    前面的“Cobbler”其实是用户描述,后面小写的cobbler才是用户名

    [root@linux-node1 cobbler]# htdigest /etc/cobbler/users.digest "Cobbler" cobbler
    Changing password for user cobbler in realm Cobbler
    New password: 
    Re-type new password: 
    [root@linux-node1 cobbler]# 
    

      

    通过密码123123登录cobbler-web成功

    可以查看配置文件

    内核参数这些东西就可以在web界面上更改

     这里也可以选择ks文件

     还可以在这上面编辑ks文件

     也可以通过页面导入dvd

    小技巧--更改cobbler装机时提示界面
     
    更改cobbler装机时提示界面
    [root@linux-node1 cobbler]# cd
    [root@linux-node1 ~]# vim /etc/cobbler/pxe/pxedefault.template
    

    这里更改为自定义的地址。

    更改之后如果想让配置生效需要执行cobbler sync 来同步最新的配置信息

    测试安装显示界面

    新建一个client

     变化了,上面链接变了

    cobbler常用目录介绍

     repo_mirror目录是默认yum仓库存放位置,这里还没有文件,因为我们还没配置自己的yum仓库

    [root@linux-node1 ~]# cd /var/www/cobbler
    [root@linux-node1 cobbler]# ls
    aux  images  ks_mirror  links  localmirror  pub  rendered  repo_mirror  svc
    [root@linux-node1 cobbler]# ls ks_mirror/
    CentOS-6-x86_64  CentOS-7-x86_64  config
    [root@linux-node1 cobbler]# ls repo_mirror/
    [root@linux-node1 cobbler]# 
    

      

    下面目录都是系统启动需要的文件

    [root@linux-node1 cobbler]# cd /var/lib/cobbler/
    [root@linux-node1 cobbler]# ls
    config                  kickstarts  lock     snippets  web.ss
    distro_signatures.json  loaders     scripts  triggers  webui_sessions

    [root@linux-node1 cobbler]# 
    
     
    cd /etc/cobbler 里面是存放所有的配置文件

    [root@linux-node1 cobbler]# 
    

      

    cobbler还可以管理dns(dnsmasq.template),其实生产中一般都是单独的dns服务器。不使用cobbler

    目前用的是cobbler2.8,  不同版本是不一样的

    [root@linux-node1 ~]# rpm -qa | grep cobbler
    cobbler-2.8.0-4.el7.x86_64
    cobbler-web-2.8.0-4.el7.noarch
    [root@linux-node1 ~]#
    

      

    Cobbler 配置结构



      Cobbler 的配置结构基于一组注册的对象。每个对象表示一个与另一个实体相关联的实体(该对象指向另一个对象,或者另一个对象指向该对象)。当一个对象指向另一个对象时,它就继承了被指向对象的数据,并可覆盖或添加更多特定信息。

    以下对象类型的定义为:
      发行版:表示一个操作系统。它承载了内核和 initrd 的信息,以及内核参数等其他数据。
      配置文件:包含一个发行版、一个 kickstart 文件以及可能的存储库,还包含更多特定的内核参数等其他数据。
      系统:表示要配给的机器。它包含一个配置文件或一个镜像,还包含 IP 和 MAC 地址、电源管理(地址、凭据、类型)以及更为专业的数据等信息。
      存储库:保存一个 yum 或 rsync 存储库的镜像信息。
      镜像:可替换一个包含不属于此类别的文件的发行版对象(例如,无法分为内核和 initrd 的对象)。
      基于注册的对象以及各个对象之间的关联,Cobbler 知道如何更改文件系统以反映具体配置。
    因为系统配置的内部是抽象的,所以您可以仅关注想要执行的操作。下面是Cobbler各对象之间的关系图,

    repository类似自定义yum源
    使用cobbler自定义yum源

     下面地址可以周到Openstack的mitaka版本的yum源

    https://mirrors.aliyun.com/centos/7.3.1611/cloud/x86_64/openstack-mitaka/

    怎么把这些源加载到自己yum仓库呢,如果你不加,得从公网下载了。很慢
    使用cobbler添加yum源
    [root@linux-node1 ~]# cobbler repo add --name=openstack-mitaka --mirror=https://mirrors.aliyun.com/centos/7.3.1611/cloud/x86_64/openstack-mitaka/ --arch=x86_64 --breed=yum
    [root@linux-node1 ~]# 
    
    这样就添加了Openstack的yum源
    公网的yum源不仅仅支持http,还支持ftp和rsync
    开始同步yum源

    同步之前先查看本地cobbler的目录中是否有文件,方便同步之后比较,目前是没有任何rpm包的

    [root@linux-node1 cobbler]# cd /var/www/cobbler
    [root@linux-node1 cobbler]# ls
    aux  images  ks_mirror  links  localmirror  pub  rendered  repo_mirror  svc
    [root@linux-node1 cobbler]# cd repo_mirror/
    [root@linux-node1 repo_mirror]# ls
    [root@linux-node1 repo_mirror]# pwd
    /var/www/cobbler/repo_mirror
    [root@linux-node1 repo_mirror]# ls
    [root@linux-node1 repo_mirror]# 
    

      

    执行下载操作,省略一部分输出

    [root@linux-node1 ~]# cobbler reposync
    .
    .
    .
    .

    received on stdout: 
    received on stderr: 
    *** TASK COMPLETE ***
    [root@linux-node1 ~]# 
    

      

     再次查看cobbler存放rpm包的位置,把Openstack-mitaka相关的包都下载了

    [root@linux-node1 repo_mirror]# pwd
    /var/www/cobbler/repo_mirror
    [root@linux-node1 repo_mirror]# ls
    openstack-mitaka
    [root@linux-node1 repo_mirror]# ls openstack-mitaka/* | wc -l
    2456
    [root@linux-node1 repo_mirror]# 
    

    总共700多MB

    [root@linux-node1 repo_mirror]# du -sh openstack-mitaka/
    732M	openstack-mitaka/
    [root@linux-node1 repo_mirror]# 
    
    它会自动帮你把阿里云下面的rpm包下载到本地,并且自动帮你创建repo文件

     

    怎么让装机的时候把Openstack的repo文件生成呢。cobbler端如下操作。
    [root@linux-node1 ~]# cobbler profile edit --name=CentOS-7-x86_64 --repo="openstack-mitaka"
    [root@linux-node1 ~]# 
    
     
    setting配置文件里面有下面东西。等于1 表示默认是开启的
    vim /etc/cobbler/settings

    ks文件里也写进去
    vim /var/lib/cobbler/kickstarts/CentOS-7-x86_64.cfg
    添加一行,如下$yum_config_stanza

    修改完毕,同步下cobbler配置信息,可以看到它在同步repo文件。
    [root@linux-node1 ~]# cobbler reposync
    task started: 2017-04-03_224404_reposync
    task started (id=Reposync, time=Mon Apr  3 22:44:04 2017)
    hello, reposync
    run, reposync, run!
    creating: /var/www/cobbler/repo_mirror/openstack-mitaka/config.repo
    creating: /var/www/cobbler/repo_mirror/openstack-mitaka/.origin/openstack-mitaka.repo
    running: /usr/bin/reposync -l -n -d --config=/var/www/cobbler/repo_mirror/openstack-mitaka/.origin/openstack-mitaka.repo --repoid=openstack-mitaka --download_path=/var/www/cobbler/repo_mirror -a x86_64
    

    添加计划任务,定期跟新yum仓库

    [root@linux-node1 ~]# echo "1 3 * * * /usr/bin/cobbler reposync --tries=3 --no-fail" >> /var/spool/cron/root
    [root@linux-node1 ~]# crontab -l
    1 3 * * * /usr/bin/cobbler reposync --tries=3 --no-fail
    [root@linux-node1 ~]# 
    

      

    总结以上过程

    1、添加repo
    cobbler repo add --name=openstack-mitaka --mirror=https://mirrors.aliyun.com/centos/7.3.1611/cloud/x86_64/openstack-mitaka/ --arch=x86_64 --breed=yum
    
    2、同步repo
    cobbler reposync
    
    3、添加repo到对应的profile
    cobbler profile edit --name=CentOS-7-x86_64 --repo="openstack-mitaka"
    
    4、修改kickstart文件,添加。(在%post %end中间)
    %post
    systemctl disable postfix.service
    
    $yum_config_stanza
    %end
    
    5、添加定时任务,定期同步repo
    echo "1 3 * * * /usr/bin/cobbler reposync --tries=3 --no-fail" >> /var/spool/cron/root
    

     

    学习使用cobbler-web界面修改,运维。安全第一。页面修改也不low
    cobbler自定义系统安装
    通过它能进行定制的需求,比如装机时mac地址和ip地址的对应,让指定的mac地址的机器获取指定的IP
    通过下面选中的部分实现此功能

     实际生产中会有很多kickstart文件,即使相同系统的kickstart文件也有不同,比如根据业务,对应不同的分区方案(web服务器和数据库服务器对磁盘分区要求就不同)

    比如新建一台虚拟机,根据mac地址给它指定一个IP地址

    规划下,给它分配这个IP
    00:50:56:31:E4:ED
    IP:192.168.58.12
    主机名:linux-node2.nmap.com
    掩码:255.255.255.0
    网关:192.168.58.2
    DNS:192.168.58.2

    自定义配置,注意下面配置需要在一行命令,这里处于美观写成了3行

    注意--name不是主机名,就是自定义的一个配置规划的名字

    [root@linux-node1 ~]# ls /var/lib/cobbler/kickstarts/CentOS-7-x86_64.cfg 
    /var/lib/cobbler/kickstarts/CentOS-7-x86_64.cfg
    [root@linux-node1 ~]# cobbler system add --name=linux-node2.nmap.com --mac=00:50:56:31:E4:ED --profile=CentOS-7-x86_64 
    --ip-address=192.168.58.12 --subnet=255.255.255.0 --gateway=192.168.58.2 --interface=eth0 --static=1 
    --hostname=linux-node2.nmap.com --name-servers="192.168.58.2" --kickstart=/var/lib/cobbler/kickstarts/CentOS-7-x86_64.cfg
    [root@linux-node1 ~]# 
    

     

    查看是否添加成功

    [root@linux-node1 ~]# cobbler system list
       linux-node2.nmap.com
    [root@linux-node1 ~]# 
    

      

    执行cobbler sync  让配置生效

    这里省略了一些输出

    [root@linux-node1 ~]# cobbler sync

     查看dhcp配置文件。末尾部分可以看到自定义的配置vim /etc/dhcp/dhcpd.conf 

     新建一个客户机并启动

    都不经过选择系统,它自动安装了,没手工干预

    下面还可以看到它的IP地址是192.168.58.12

     查看安装完毕的系统

    cobbler-api


    相关一些python脚本

    [root@linux-node1 ~]# mkdir /scripts -p
    [root@linux-node1 ~]# cd /scripts/
    [root@linux-node1 scripts]# vim cobbler_list.py
    

    新建一个cobbler_list.py 的脚本

    [root@linux-node1 scripts]# cat cobbler_list.py 
    #!/usr/bin/python
    import xmlrpclib
    server = xmlrpclib.Server("http://192.168.58.11/cobbler_api")
    print server.get_distros()

    print server.get_systems()
    print server.get_images()
    print server.get_repos()
    [root@linux-node1 scripts]# 
    

    它能通过调用cobbler的api输出一些当前信息。格式是列表 

    api的文档可以通过官网查看,它的官方文档地址
    cobbler.github.io
     
    下面通过api实现指定mac地址的机器自动装机

    生成一个mac地址

     脚本内容如下

    注意mac地址是取上面的,规划给这个mac地址的主机分配IP是192.168.58.111,主机名是cobbler-api-test

    注意cobbler-api的用户名和密码和网页登录的一致

    #!/usr/bin/env python 
    # -*- coding: utf-8 -*-
    import xmlrpclib 
    class CobblerAPI(object):
        def __init__(self,url,user,password):
            self.cobbler_user= user
            self.cobbler_pass = password
            self.cobbler_url = url
        def add_system(self,hostname,ip_add,mac_add,profile):
            '''
            Add Cobbler System Infomation
            '''
            ret = {
                "result": True,
                "comment": [],
            }
            #get token
            remote = xmlrpclib.Server(self.cobbler_url) 
            token = remote.login(self.cobbler_user,self.cobbler_pass) 
            #add system
            system_id = remote.new_system(token) 
            remote.modify_system(system_id,"name",hostname,token) 
            remote.modify_system(system_id,"hostname",hostname,token) 
            remote.modify_system(system_id,'modify_interface', { 
                "macaddress-eth0" : mac_add, 
                "ipaddress-eth0" : ip_add, 
                "dnsname-eth0" : hostname, 
            }, token) 
            remote.modify_system(system_id,"profile",profile,token) 
            remote.save_system(system_id, token) 
            try:
                remote.sync(token)
            except Exception as e:
                ret['result'] = False
                ret['comment'].append(str(e))
            return ret
    def main():
        cobbler = CobblerAPI("http://192.168.58.11/cobbler_api","cobbler","123123")
        ret = cobbler.add_system(hostname='cobbler-api-test',ip_add='192.168.58.111',mac_add='00:50:56:27:EC:40',profile='CentOS-7-x86_64')
        print ret
    if __name__ == '__main__':
        main()
    

      

     通过执行上面脚本,在cobber在自己系统里加入一条记录,关于此mac地址的主机配置要求

    [root@linux-node1 scripts]# vim cobbler_system_api.py
    [root@linux-node1 scripts]# pwd
    /scripts
    [root@linux-node1 scripts]# ll
    total 8
    -rw-r--r-- 1 root root  234 Apr  3 23:51 cobbler_list.py
    -rw-r--r-- 1 root root 1533 Apr  4 00:01 cobbler_system_api.py
    [root@linux-node1 scripts]# 
    

      

    添加成功,这个mac地址的机器启动之后就自动装机了

    [root@linux-node1 scripts]# cobbler system list
       linux-node2.nmap.com
    [root@linux-node1 scripts]# python cobbler_system_api.py 
    {'comment': [], 'result': True}
    [root@linux-node1 scripts]# cobbler system list
       cobbler-api-test
       linux-node2.nmap.com
    [root@linux-node1 scripts]# 
    

      

     启动此新建的机器。看到自动装机了,获取的IP地址就是上面指定的

     安装完毕,登录检查

    安装完的系统,yum源也会多出之前定义的Openstack-mitaka的源

    之所以kickstart能装机后配置IP和主机名等,就是上面这些脚本实现的
    [root@linux-node1 scripts]# cd /var/lib/cobbler/snippets/
    [root@linux-node1 snippets]# ll post_install_network_config
    -rw-r--r-- 1 root root 16281 Nov 17 03:09 post_install_network_config
    [root@linux-node1 snippets]# ls

    查看官方文档,网卡绑定部分

    http://cobbler.github.io/manuals/2.8.0/

    这里能实现,装机后多网卡绑定
    下面4条命令可以实现
    mode=1 表示主备模式,mode=0表示负载均衡
