cobbler服务端部署
说明：虚拟机网卡采用NAT模式或者仅主机模式，不要使用桥接模式，因为后面会搭建DHCP服务器，在同一个局域网多个DHCP服务会有冲突。
环境准备
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# setenforce 0
[root@localhost ~]# sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/sysconfig/selinux
安装cobbler
# 配置epel源
[root@localhost ~]# yum -y install epel-release
# 安装cobbler以及相关的软件
[root@localhost ~]# dnf module enable cobbler:3 -y
[root@localhost ~]# yum -y install httpd dhcp* tftp tftp-server cobbler cobbler-web pykickstart rsync rsync-daemon
# 启动服务并设置开机自启
[root@localhost ~]# systemctl enable --now httpd
[root@localhost ~]# systemctl enable --now rsyncd
[root@localhost ~]# systemctl enable --now tftp
[root@localhost ~]# systemctl enable --now cobblerd
配置cobbler
[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:
1: The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or automatic installation features will not work. This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
2: For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
3: SELinux is enabled. Please review the following wiki page for details on ensuring Cobbler works correctly in your SELinux environment:
https://github.com/cobbler/cobbler/wiki/Selinux
4: some network boot-loaders are missing from /var/lib/cobbler/loaders. If you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, and yaboot.
5: reposync is not installed, install yum-utils or dnf-plugins-core
6: yumdownloader is not installed, install yum-utils or dnf-plugins-core
7: debmirror package is not installed, it will be required to manage debian deployments and repositories
8: The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one
9: 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.
看到上面出现的问题，然后一个一个的进行解决，先进行设置为可以动态配置，也可以直接更改配置文件。
