實驗1：在centos7上cobbler實現pxe的自動化安裝
（1）A機器，搭建cobbler的配置
yum install cobbler cobbler-web 安裝時依賴安裝的包有tftp-server、httpd
yum install dhcp
systemctl enable httpd
systemctl start httpd
systemctl enable tftp
systemctl start tftp
rpm -ql cobbler|grep service
systemctl start cobblerd
cobbler check
vim /etc/cobbler/settings
server: 172.18.62.60
systemctl restart cobblerd
cobbler check
vim /etc/cobbler/settings
next_server: 172.18.62.60
systemctl restart cobblerd
cobbler check
openssl passwd -1 生成加密的密碼
vim /etc/cobbler/settings 復制密碼
default_password_crypted: "$1$9CWphr2E$deIQsrb3oZPmQ/7YkZoC30"
systemctl restart cobblerd
cobbler check
cobbler get-loaders
systemctl restart cobblerd
cobbler check
yum install pykickstart
systemctl restart cobblerd
cobbler check
vim /etc/cobbler/settings
manage_dhcp: 1 必須啟用，否則不能自動生成dhcp配置文件
vim /etc/cobbler/dhcp.template
option routers 172.18.62.5;
option domain-name-servers 114.114.114.114,8.8.8.8;
option subnet-mask 255.255.0.0;
range dynamic-bootp 172.18.62.90 172.18.62.200;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server; 變量自動獲取地址
systemctl restart cobblerd
cobbler check
cobbler sync
ss -nutl
systemctl enable dhcpd
fconfig ens37 down
systemctl start dhcpd
systemctl status dhcpd
ss -nutl
ls /var/lib/tftpboot/
tree /var/www/
mkdir /mnt/centos6
添加centos6的光盤
echo "- - -" > /sys/class/scsi_host/host0/scan
echo "- - -" > /sys/class/scsi_host/host1/scan
echo "- - -" > /sys/class/scsi_host/host2/scan
mount /dev/sr1 /mnt/centos6
ls /mnt/centos6
cobbler import --path=/mnt/centos7/ --name=Centos7.4 將光盤導入cobbler中，並
設置默認應答文件；
cobbler import --path=/mnt/centos6/ --name=centos6.9 --arch=x86_64
cobbler profile list
cobbler distro list
cd /var/lib/cobbler/
cd kickstarts/
rz 將自定義的ks應答文件導入到此目錄
chmod 644 * 設置ks文件可讀
vim ks7-pxe-desktop.cfg
url --url=$tree 變量自動找到系統鏡像的路徑
vim ks6-pxe-desktop.cfg
url --url=$tree 變量自動找到系統鏡像的路徑
cobbler profile list 顯示啟動菜單項
cobbler distro list 顯示系統鏡像
cobbler profile add --name=Centos7.4-x86_64-desktop --distro=Centos7.4-x86_64 --kickstart=/var/lib/cobbler/kickstarts/ks7-pxe-desktop.cfg 添加啟動菜單項
cobbler profile add --name=Centos6.9-x86_64-desktop --distro=centos6.9-x86_64 --kickstart=/var/lib/cobbler/kickstarts/ks6-pxe-desktop.cfg 添加啟動菜單項

（2）要安裝的機器的配置
關閉自動獲取本地dhcp選項
設置網絡模式
設置硬盤大小以適應ks中的分區
設置內存大小以防centos7圖形安裝內存不夠
進入啟動項界面，選擇網絡引導，以安裝系統
實驗2：centos6上實現cobbler自動化安裝系統
（1）A機器搭建cobbler配置
yum install dhcp httpd syslinux tftp-server
cd /etc/yum.repos.d/
vim epel.repo
[epel]
name=epel_centos6
baseurl=https://mirrors.aliyun.com/epel/6/x86_64/
gpgcheck=0
yum repolist
yum install cobbler cobbler需要epel源提供包
service cobblerd start
chkconfig cobblerd on
chkconfig tftp on
service xinetd start
chkconfig --list
rpm -ql tftp-server
service httpd restart
vim /etc/cobbler/dhcp.template
option routers 172.18.62.5;
option domain-name-servers 223.5.5.5,8.8.8.8;
option subnet-mask 255.255.0.0;
range dynamic-bootp 172.18.62.200 172.18.62.254;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
vim /etc/cobbler/settings
manage_dhcp: 1 必須有
next_server: 172.18.62.50
server: 172.18.62.50
default_password_crypted: "$1$K1U0gpRl$BXEnaaYVdarbjYbHP6WVh0"
註意：默認密碼需要用openssl passwd -1命令生成
cobbler check
cobbler get-loaders
yum install pykickstart -y
vim /etc/xinetd.d/rsync
disable = no
service cobblerd restart
cobbler check
cobbler sync

cobbler profile --help
cobbler profile rename --help
cobbler profile rename --name=Centos6.9-x86_64 --newname=Centos6.9-mini-x86_64
重命名啟動菜單；
cobbler profile rename --name=Centos7.4-x86_64 --newname=Centos7.4-mini-x86_64
重命名啟動菜單；
cd /var/lib/cobbler/kickstarts/
rz 導入ks應答文件
vim ks6-pxe-desktop.cfg
url --url=$tree
vim ks7-pxe-desktop.cfg
url --url=$tree
cobbler profile add --name=Centos7.4-desktop-x86_64 --distro=Centos7.4-x86_64 --kickstart=ks7-pxe-desktop.cfg 添加啟動菜單
cobbler profile add --name=Centos7.4-desktop-x86_64 --distro=Centos7.4-x86_64 --kickstart=/var/lib/cobbler/kickstarts/ks7-pxe-desktop.cfg 添加啟動菜單
cobbler profile add --name=Centos6.9-desktop-x86_64 --distro=Centos6.9-x86_64 --kickstart=/var/lib/cobbler/kickstarts/ks6-pxe-desktop.cfg 添加啟動菜單
cat /var/lib/tftpboot/pxelinux.cfg/default 查看添加菜單後的啟動菜單文件

（2）要安裝的機器的配置
關閉自動獲取本地dhcp選項
設置網絡模式
設置硬盤大小以適應ks中的分區
設置內存大小以防centos7圖形安裝內存不夠
