1、配置EPEL源
[root@cobbler ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo yum clean all &&yum makecache2、安装cobbler
[root@cobbler ~]yum install -y httpd tftp dhcp cobbler cobbler-web pykickstart3、查看cobbler安装文件
[root@linux-node2 ~]# rpm -ql cobbler /etc/cobbler # 配置文件目录 /etc/cobbler/settings # cobbler主配置文件，这个文件是YAML格式，Cobbler是python写的程序。 /etc/cobbler/dhcp.template # DHCP服务的配置模板 /etc/cobbler/tftpd.template # tftp服务的配置模板 /etc/cobbler/rsync.template # rsync服务的配置模板 /etc/cobbler/iso # iso模板配置文件目录 /etc/cobbler/pxe # pxe模板文件目录 /etc/cobbler/power # 电源的配置文件目录 /etc/cobbler/users.conf # Web服务授权配置文件 /etc/cobbler/users.digest # 用于web访问的用户名密码配置文件 /etc/cobbler/dnsmasq.template # DNS服务的配置模板 /etc/cobbler/modules.conf # Cobbler模块配置文件 /var/lib/cobbler # Cobbler数据目录 /var/lib/cobbler/config # 配置文件 /var/lib/cobbler/kickstarts # 默认存放kickstart文件 /var/lib/cobbler/loaders # 存放的各种引导程序 /var/www/cobbler # 系统安装镜像目录 /var/www/cobbler/ks_mirror # 导入的系统镜像列表 /var/www/cobbler/images # 导入的系统镜像启动文件 /var/www/cobbler/repo_mirror # yum源存储目录 /var/log/cobbler # 日志目录 /var/log/cobbler/install.log # 客户端系统安装日志 /var/log/cobbler/cobbler.log # cobbler日志4、启动服务
[root@cobbler cobbler]# systemctl start httpd && systemctl start cobblerd5、检查cobbler
[root@cobbler cobbler]# 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 kickstarting 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 : change 'disable' to 'no' in /etc/xinetd.d/tftp 5 : Some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, 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, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements. 6 : enable and start rsyncd.service with systemctl 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.根据check信息修改配置文件
