cobbler批量安裝客戶端
阿新 • • 發佈：2018-12-16
關閉防火牆、selinux然後重啟一下虛擬機器
配置yum源
[[email protected] ~]# curl -o /etc/yum.repos.d/CentOS7-Base-163.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
[[email protected] ~]# sed -i 's/\$releasever/7/g' /etc/yum.repos.d/CentOS7-Base-163.repo
[[email protected] ~]# sed -i 's/^enabled=.*/enabled=1/g' /etc/yum.repos.d/CentOS7-Base-163.repo
[ 安裝cobbler以及相關的軟體
[[email protected] ~]# yum -y install httpd dhcp tftp python-ctypes cobbler xinetd cobbler-web pykickstart
安裝過程略。。。
啟動服務並設定開機自啟
[[email protected] ~]# systemctl start httpd.service
[[email protected] 下載缺失檔案
[[email protected] ~]# cobbler get-loaders

啟動rsync並設定開機自啟
[[email protected] ~]# systemctl start rsyncd
[[email protected] ~]# systemctl enable rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.
生成加密的密碼
[[email protected] ~]# openssl passwd -1 -salt "$RANDOM" 'wangqing123!'
$1$16884$gNXHahIREtcHhmHVTxzGF. //這是密碼加密後的形式
//將新生成的加密密碼加入到配置檔案
[[email protected] ~]# vim /etc/cobbler/settings
。。。
default_password_crypted: "$1$16884$gNXHahIREtcHhmHVTxzGF."
。。。
重啟cobbler
[[email protected] ~]# systemctl restart cobblerd.service
[[email protected] ~]# ss -antl

通過cobbler check核對當前設定是否有問題
[[email protected] ~]# cobbler check
The following are potential configuration items that you may want to fix:
1 : debmirror package is not installed, it will be required to manage debian deployments and repositories
2 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
Restart cobblerd and then run 'cobbler sync' to apply changes.
//以上兩個是關於debian系統的錯誤，請忽略
配置cobbler dhcp
修改cobbler配置檔案，讓cobbler控制dhcp
登入：賬號密碼都為cobbler
設定manage_dhcp為1
配置dhcp
[[email protected] ~]# vim /etc/cobbler/dhcp.template
subnet 192.168.102.0 netmask 255.255.255.0 {
option routers 192.168.102.11;
option domain-name-servers 192.168.102.11;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.102.100 192.168.102.120;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
重啟服務並同步配置，改完dhcp必須要sync同步配置
