站長資訊網1、修改YUM倉庫
vim /etc/yum.repos.d/my.repo
[epel]
name=epel
baseurl=https://mirrors.aliyun.com/epel/7Server/x86_64/
enabled=1
gpgcheck=0
2、安裝cobbler
yum install dhcp httpd xinetd tftp cobbler cobbler-web -y
3、修改cobbler配置文件
生成加密密碼：openssl passwd -1 -salt bw.com 123456
vim /etc/cobbler/settings
server: 192.168.100.100
next_server: 192.168.100.100
default_password_crypted: "$1$stu.com$Pp0HQwZhSF…mXIxjJAH." #root管理員密碼
4、配置DHCP
vim /etc/dhcpd/dhcp.conf
option domain-name "stu.com";
option domain-name-servers 192.168.100.100;
default-lease-time 36000;
max-lease-time 72000;
log-facility local7;
subnet 192.168.100.0 netmask 255.255.255.0 {
range 192.168.100.110 192.168.100.150;
option routers 192.168.100.1;
option broadcast-address 192.168.100.255;
next-server 192.168.100.100;
filename "pxelinux.0";
}
systemctl start dhcpd
systemctl enable dhcpd
5、配置tftp
vim /etc/xinetd.d/tftp
disable= no
systemctl start xinetd
systemctl enable xinetd
6、下載啟動引導文件
cobbler get-loaders
7、導入光盤鏡像文件
cobbler import –path=/mnt/cdrom –name=c75 –arch=x86_64
vim /var/lib/cobbler/kickstarts/c75.ks
#platform=x86, AMD64, Intel EM64T
#version=DEVEL
#Install OS instead of upgrade
install
#Keyboard layouts
keyboard 'us'
#Root password
rootpw –iscrypted $default_password_crypted #見第3步
#System timezone
timezone Asia/Shanghai
#Use network installation
url –url=$tree
#System language
lang en_US.UTF-8
#Firewall configuration
firewall –disabled
#System authorization information
auth –useshadow –enablemd5
#Use graphical install
text
firstboot –disable
#SELinux configuration
selinux –disabled
#Reboot after installation
reboot
#System bootloader configuration
bootloader –location=mbr
#Clear the Master Boot Record
zerombr
#Partition clearing information
clearpart –all –initlabel
#Disk partitioning information
part /boot –fstype="xfs" –size=256
part swap –fstype="swap" –size=1024
part / –fstype="xfs" –ondisk=sda –size=1 –grow #使用全部剩余空間
#Network information
$SNIPPET('network_config')
%pre
$SNIPPET('log_ks_pre')
$SNIPPET('kickstart_start')
$SNIPPET('pre_install_network_config')
#Enable installation monitoring
$SNIPPET('pre_anamon')
%end
%packages@^minimal
br>@core

%end
%addon com_redhat_kdump –disable –reserve-mb='auto'
%end
%post
#Start yum configuration

%post
sed -i "1s/5/0/" /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg
rm -f /etc/yum.repos.d/CentOS*
yum remove NetworkManager -y
%end
二、cobbler配置
1、編輯profile
cobbler profile edit –name=c75-x86_64 –kickstart=/var/lib/cobbler/kickstarts/c75.ks
cobbler profile edit –name=c75-x86_64 –kopts='net.ifnames=0 biosdevname=0 ipv6.disable=1'
2、客戶端默認local啟動
vim /etc/cobbler/pxe/pxedefault.template
DEFAULT menu
PROMPT 0
MENU TITLE Cobbler | http://cobbler.github.io/
TIMEOUT 1
TOTALTIMEOUT 6000
ONTIMEOUT $pxe_timeout_profile
LABEL local
MENU LABEL (local)
MENU DEFAULT
LOCALBOOT -1
$pxe_menu_items
MENU end
cobbler system add –name=default –profile=c75-x86_64
cobbler sync
3、配置IP信息及主機名
cobbler system add –name=lbmaster –profile=c75-x86_64 –kickstart=/var/lib/cobbler/kickstarts/c75.ks
–interface=eth0 –static=1 –mac=00:50:56:20:38:C8 –ip-address=192.168.100.10 –subnet=255.255.255.0 –gateway=192.168.100.1
–name-servers="192.168.100.100" –hostname=lbmaster.stu.com
4、配置YUM倉庫
(1)同步網絡YUM倉庫
cobbler repo add –name=openstack –mirror=https://mirrors.aliyun.com/centos/7.5.1804/cloud/x86_64/openstack-ocata/ –arch=x86_64 –breed=yum
cobbler repo add –name=zabbix –mirror=https://mirrors.aliyun.com/zabbix/zabbix/3.5/rhel/7/x86_64/ –arch=x86_64 –breed=yum
cobbler reposync
cobbler profile edit –name=c75-x86_64 –kickstart=/var/lib/cobbler/kickstarts/c75-cobbler.ks –repos="openstack"
測試、生產環境中，有時并不需要在本地安裝一個mysql server服務，只需要安裝一個登錄mysql server 的mysql的客戶端client
centos6系統上安裝mysql-client的方式：
yum install mysql-clent mysql-devel -y
centos7的系統上安
測試、生產環境中，有時并不需要在本地安裝一個mysql server服務，只需要安裝一個登錄mysql server 的mysql的客戶端client
centos6系統上安裝mysql-client的方式：
yum install mysql-clent mysql-devel -y
centos7的系統上安裝mysql client的方式：

裝mysql client的方式：
yum install -y mariadb.x86_64 mariadb-libs.x86_64
/> crontab -e
cobbler reposync –tries=3 –no-fail
(2)修改默認YUM倉庫配置文件
vim /var/www/cobbler/ks_mirror/config/c75-x86_64.repo
[core-0]name=core-0
baseurl=http://@@http_server@@/cobbler/ks_mirror/c75-x86_64
br>name=core-0
baseurl=http://@@http_server@@/cobbler/ks_mirror/c75-x86_64
gpgcheck=0
priority=$yum_distro_priority
[epel]
names=epel
baseurl=https://mirrors.aliyun.com/epel/7Server/x86_64/
enabled=1
gpgcheck=0
systemctl start cobblerd
systemctl enable cobblerd
cobbler sync
