软件包安装并关闭SELinux

– 配置epel源，直接使用yum安装

yum install cobbler cobbler-web dhcp bind pykickstart tftp -y

需要注意dhcp/bind需要单独安装一下，cobbler没依赖dhcp/bind

sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config
setenforce 0
```bash
systemctl restart cobblerd

配置cobbler参数 – 修改/etc/cobbler/settings的参数


allow_dynamic_settings: 1
```bash
default_password_crypted: "$1$random-p$yqLCVPP/OBjIT02WekZic1"

next_server: 192.168.117.134 manage_dhcp: 1 manage_dns: 1 server: 192.168.117.134 manage_rsync: 1 pxe_just_once: 1 #防止循环装机 manage_forward_zones: [‘gnuers.org’]

manage_reverse_zones: ['10.0.0', '192.168', '172.16.123']
- 修改dhcp池配置 /etc/cobbler/dhcp.template

subnet 192.168.117.0 netmask 255.255.255.0 { option routers 192.168.117.2; option domain-name-servers 192.168.117.2; option subnet-mask 255.255.255.0; range dynamic-bootp 192.168.117.10 192.168.117.20;

- 修改/etc/cobbler/named.template配置，named监听所有IP

options { listen-on port 53 { any; }; directory “/var/named”; dump-file “/var/named/data/cache_dump.db”; statistics-file “/var/named/data/named_stats.txt”;

memstatistics-file "/var/named/data/named_mem_stats.txt";

allow-query { localhost; }; recursion yes; };

- 获取网络loader（本机有syslinux可以不安装）

cobbler get-loaders

- 开启cobbler服务
systemctl enable cobblerd &&
systemctl start cobblerd
systemctl enable httpd &&
systemctl start httpd
systemctl enable rsyncd.service &&
systemctl start rsyncd.service
systemctl enable tftp &&
systemctl start tftp

配置cobbler-web的密码

htdigest /etc/cobbler/users.digest "Cobbler" cobbler

配置后可以打开https://192.168.117.134/cobbler_web 登陆web页面– 确认cobbler配置

cobbler check

导入安装镜像

– 挂载ISO到本地并导入cobbler直接导入会给建立一个默认的profile，使用的ks是 /var/lib/cobbler/kickstarts/sample_end.ks

mount CentOS-7u2.iso /mnt/CentOS7U2

cobbler import –arch=x86_64 –breed=redhat –os-version=rhel7 –path=/mnt/CentOS7U2/ –name=CentOS7U2

查看命令

cobbler profile list
cobbler profile remove --name CentOS7U2-x86_64
cobbler distro list
cobbler distro remove --name CentOS7U2-x86_64

添加自己的profile

– 先配置自己的ks文件，再做profile添加新增自己修改过的ks文件到var/lib/cobbler/kickstarts/7u2diy.ks

cobbler profile add –name=Centos7U2-DIY –distro=CentOS7U2-x86_64 –kickstart=/var/lib/cobbler/kickstarts/7u2diy.ks

- 设置自动运行的profile直接修改/var/lib/tftpboot/pxelinux.cfg/default 中ONTIMEOUT为Centos7U2-DIY

创建system给特定的机器按指定的模板做自动安装

cobbler system add –name=VMDIY –profile=Centos7U2-DIY –interface=eth0 –mac=00:0c:29:e7:a2:e4 –gateway=192.168.117.2 –ip-address=192.168.117.66 –netmask=255.255.255.0 –static=1 –dns-name=test.alipay.com mac地址为00:0c:29:e7:a2:e4的服务器开启后会按预设的模板进行装机，并分配指定IP如果想重装已经装过的服务器，需要先设置netboot标志

cobbler system edit –name=VMDIY –netboot-enabled=1

cobbler sync

    ## 命令说明
1. 镜像相关的操作

[root@Centos kickstarts]# cobbler distro ## usage

cobbler distro add cobbler distro copy cobbler distro edit cobbler distro find cobbler distro list cobbler distro remove cobbler distro rename cobbler distro report

1. 安装模板配置

[root@Centos kickstarts]# cobbler profile usage

cobbler profile add cobbler profile copy cobbler profile dumpvars cobbler profile edit cobbler profile find cobbler profile getks cobbler profile list cobbler profile remove cobbler profile rename cobbler profile report

添加发型版支持编辑 /var/lib/cobbler/distro_signatures.json [root@Centos kickstarts]# cobbler signature reload usage ===== cobbler signature reload cobbler signature report cobbler signature update

    ## 遇到的问题
1. 内存不足，VM 只分了1G 内存
mount: wrong fs type, bad option, bad superblock on /dev/loop0

missing codepage or helper program, or other error in some cases useful info is found in syslog - try

dmesg | tail or so
umount: /run/initramfs/squashfs: not mounted
```bash
/sbin/dmsquash-live-root: line 273: printf: write error: no space left on device
1. 开启gpxe后无法安装因为渲染出来的启动菜单的参数有问题,启动不了的时候都可以看看pxe的菜单内的参数是否正常 /var/lib/tftpboot/pxelinux.cfg/default
