一父款、配置chrony服務(wù)，實現(xiàn)服務(wù)器時間自動同步
1、安裝chrony
yum -y install chrony #安裝服務(wù)
systemctl enable chronyd #開機啟動
systemctl start chronyd #啟動服務(wù)
2簸州、服務(wù)端配置
vim /etc/chrony.conf 清空默認配置,添加如下配置內(nèi)容
server s1a.time.edu.cn iburst #添加外部時間源
server s1a.time.edu.cn iburst
server ntp.aliyun.com iburst
local stratum 10 #網(wǎng)絡(luò)時間同步失敗醇坝，將本地時間同步給client
allow 192.168.1.0/24 #允許客戶端連接的網(wǎng)段
3延蟹、客戶端配置
vim /etc/chrony.conf 清空默認配置窍仰，添加如下配置內(nèi)容
server 192.168.1.1 iburst #添加chrony服務(wù)器IP
4将硝、查看同步情況
chronyc sources –v
二岩四、實現(xiàn)cobbler+pxe自動化裝機
1哭尝、安裝初始環(huán)境并啟動服務(wù)
yum install httpd dhcp tftp-server xinetd -y
service dhcpd start
service httpd start
vim /etc/xinetd.d/tftp
disable = no
service xinetd start
2、關(guān)閉selinux及防火墻
systemctl disabled firewalld && systemctl stop firewalld
setenforce 0
3剖煌、安裝cobbler
yum install cobbler -y
4材鹦、檢查cobbler配置
cobbler check
5逝淹、編輯cobbler配置文件
next_server: 172.16.23.242
manage_dhcp: 1
server: 172.16.23.242 。
default_password_crypted: "$1$og3rjhWd$iBVqBzuesn5S25lwzdB6C/" #初始密碼123456
systemctl restart cobblerd
6桶唐、編輯dhcp模板
vi /etc/cobbler/dhcp.template
subnet 172.16.23.0 netmask 255.255.255.0 {
option routers 172.16.23.242;
option domain-name-servers 172.16.23.242;
option subnet-mask 255.255.255.0;
range dynamic-bootp 172.16.23.230 172.16.23.245;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
}
7栅葡、下載loader文件并同步配置
cobbler get-loaders
cobbler sync
8、鏡像準(zhǔn)備
mkdir -p /mnt/cdrom
mount /dev/cdrom /mnt/cdrom/
cobbler import --path=/mnt/cdrom --name=centos7 --arch=x86_64
9尤泽、為鏡像創(chuàng)建自動應(yīng)答文件
cp /root/anaconda-ks.cfg /var/lib/cobbler/kickstarts/centos7-ks.cfg
vi /var/lib/cobbler/kickstarts/centos7-ks.cfg
install
url --url=$tree
cobbler profile edit --name=centos7-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos7-ks.cfg
cobbler sync
10欣簇、客戶端配置
客戶端與cobbler在同一個網(wǎng)段
開機進入bios，選擇從網(wǎng)卡啟動
