#### 任何修改后，重新同步cobbler配置，配置生效 ```shell cobbler sync ``` #### 導入安裝鏡像 **掛載光盤** ``` mount -t iso9660 -o loop /tmp/CentOS-7-x86_64-DVD-1611.iso /mnt/ ``` **掛載Centos 6.8光盤鏡像到/mnt目錄下，導入** ```shell cobbler import --name=Centos-6.8 --path=/mnt/ --arch=x86_64 ``` **掛載Centos 7.3光盤鏡像到/mnt目錄下，導入** ```shell cobbler import --name=Centos-7.3 --path=/mnt/ --arch=x86_64 ``` **掛載ESXI 5.5光盤鏡像到/mnt目錄下，導入** ```shell cobbler import --path=/mnt/ --name=ESXI-5.5.0 --arch=x86_64 ``` #### 查看distro配置 ```shell cobbler distro report ``` #### 定義自動安裝的應答文件，文件放到/var/lib/cobbler/kickstarts/目錄下 > Cobbler通過讀取該文件，執行相關安裝步驟請查看1.5 Cobbler 配置文件 #### 為可用鏡像配置默認ks文件 **Centos 6.8** ```shell cobbler profile edit --name=Centos-6.8-x86_64 --kickstart=/var/lib/cobbler/kickstarts/Centos-6.8-x86_64.cfg ``` **Centos 7.3** ```shell cobbler profile edit --name=Centos-7.3-x86_64 --kickstart=/var/lib/cobbler/kickstarts/Centos-7.3-x86_64.cfg ``` **ESXI 5.5** ```shell cobbler profile edit --name=ESXI-5.5.0-x86_64 --kickstart=/var/lib/cobbler/kickstarts/esxi5.5.cfg ``` #### 調整網卡內核參數（標準化，名稱統一,關閉IPv6） **Centos 7.3** ```shell cobbler profile edit --name=Centos-7.3-x86_64 --kopts='net.ifnames=0 biosdevname=0 noipv6' ``` #### 查看profile配置 ```shell cobbler profile report ``` #### 建立本地yum源 **Centos 6.8** ```shell cobbler repo add --name=Centos-6-x86_64 --mirror=https://mirrors.aliyun.com/centos/6.9/os/x86_64/ --arch=x86_64 --breed=yum --keep-update=Y cobbler repo add --name=Centos-6-epel-x86_64 --mirror=https://mirrors.aliyun.com/epel/6Server/x86_64/ --arch=x86_64 --breed=yum --keep-update=Y ``` **Centos 7.x** ```shell cobbler repo add --name=Centos-7-x86_64 --mirror=https://mirrors.aliyun.com/centos/7.4.1708/os/x86_64/ --arch=x86_64 --breed=yum --keep-update=Y cobbler repo add --name=Centos-7-epel-x86_64 --mirror=https://mirrors.aliyun.com/epel/7Server/x86_64/ --arch=x86_64 --breed=yum --keep-update=Y cobbler repo add --name=zabbix3.0-Centos7 --mirror=http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/ --arch=x86_64 --breed=yum --keep-update=Y ``` #### 查看repo配置 ```shell cobbler repo report ``` **執行同步任務** ```shell cobbler reposync ``` 錯誤一例： Exception occured: <class 'cobbler.cexceptions.CX'> Exception value: 'cobbler reposync failed' 解決方法1：把--breed=yum更換為rsync或wget **建立任務計劃，每周六同步一次** ```shell echo "0 23 * * 6 /usr/bin/cobbler reposync >> /app/log/cobbler.log 2>&1" >> /var/spool/cron/root ``` **重啟Cron** **Centos 6.8** ```shell /etc/init.d/crond restart ``` **Centos 7.3** ```shell systemctl restart crond ``` #### 為鏡像配置本隊YUM源 **Centos 6.8** ```shell cobbler profile edit --name=Centos-6.8-x86_64 --repos="Centos-6-epel-x86_64 Centos-6.8-x86_64-extras Centos-6.8-x86_64-os Centos-6.8-x86_64-updates Centos-6.8-x86_64-cr Centos-6.8-x86_64-gfs zabbix3.0-Centos6" ``` **Centos 7.3** ```shell cobbler profile edit --name=Centos-7.3-x86_64 --repos="Centos-7.3-x86_64-os Centos-7.3-x86_64-updates Centos-7.3-x86_64-extras Centos-7-epel-x86_64 Centos-7.3-x86_64-cloud-l Centos-7.3-x86_64-gfs zabbix3.0-Centos7" ``` #### 根據MAC地址零交互安裝 ** 創建一個新的自定義安裝** ```shell cobbler system add --name=odb01.prod.ding --mac=00:0c:29:34:58:f1 --profile=Centos-6.8-x86_64 --ip-address=192.168.0.20 --subnet=255.255.255.0 --gateway=192.168.0.1 --interface=eth0 --static=1 --hostname=odb01.prod.ding --name-servers="114.114.114.114" ``` #### 修改自定義安裝（name不可修改） ```shell cobbler system edit --name=odb01.prod.ding --mac=00:0c:29:34:58:f1 --profile=Centos-6.8-x86_64 --ip-address=192.168.0.20 --subnet=255.255.255.0 --gateway=192.168.0.1 --interface=eth0 --static=1 --hostname=odb01.prod.ding --name-servers="114.114.114.114" ``` #### 查看system配置 ```shell cobbler system report ``` #### 修改展示頁面內容 ```shell [root@Centos-souce kickstarts]# cat /etc/cobbler/pxe/pxedefault.template DEFAULT menu PROMPT 0 MENU TITLE Cobbler | 系統自動化部署 TIMEOUT 200 TOTALTIMEOUT 6000 ONTIMEOUT $pxe_timeout_profile LABEL local MENU LABEL (local) MENU DEFAULT LOCALBOOT -1 $pxe_menu_items MENU end ``` #### 自動重裝系統（注意：客戶機配置）問題：雖然可以重裝系統，但是不能設置IP、DNS、主機名解決： - 重裝時候，生成專門為這臺機器使用的一次性系統profile,用完即刪 - 將自定義操作交由saltstack或者ansible來做，但是IP地址怎么分配呢？ - 通過dell的IDRAC等遠程管理卡的遠程界面，手工PXE啟動（個人推薦） **安裝epel源，安裝koan** ```shell yum install koan -y ``` **獲取Cobbler服務器上的可用系統列表** ```shell [root@openstack ~]# koan --server=192.168.0.232 --list=profiles - looking for Cobbler at http://192.168.0.232:80/cobbler_api Centos-7.3-x86_64 ``` **選擇要重裝的系統，執行安裝命令** ```shell koan --replace-self --server=192.168.0.232 --profile=Centos-7.3-x886_64 ``` #### 1.2.3 Cobbler WEB配置 ```shell https://192.168.0.232/cobbler_web ```
