检测cobbler
cobbler的运行依赖于dhcp、tftp、rsync及dns服务，其中dhcp可由dhcpd（isc）提供，也可由dnsmasq提供；tftp可由tftp-server程序包提供，也可由cobbler功能提供，rsync有rsync程序包提供，dns可由bind提供，也可由dnsmasq提供
cobbler可自行管理这些服务中的部分甚至是全部，但需要配置/etc/cobbler/settings文件中的“manange_dhcp”、“manager_tftpd”、“manager_rsync”、“manager_dns”分别来进行定义，另外，由于各种服务都有着不同的实现方式，如若需要进行自定义，需要通过修改/etc/cobbler/modules.conf配置文件中各服务的模块参数的值来实现
#重启httpd服务及cobbler服务后进行检测
[root@cobbler ~]# systemctl restart httpd
[root@cobbler ~]# systemctl restart cobblerd
[root@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 : change 'disable' to 'no' in /etc/xinetd.d/tftp
4 : 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.
5 : enable and start rsyncd.service with systemctl
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
7 : 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
8 : 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.
修改配置文件逐条解决上述8个问题
#先备份cobbler主配置文件
[root@cobbler ~]# cd /etc/cobbler/
[root@cobbler cobbler]# cp settings settings.bak
[root@cobbler cobbler]# ls
auth.conf dnsmasq.template modules.conf reporting settings.bak zone.template
cheetah_macros genders.template mongodb.conf rsync.exclude tftpd.template zone_templates
cobbler_bash import_rsync_whitelist named.template rsync.template users.conf
completions iso power secondary.template users.digest
dhcp.template ldap pxe settings version
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.
解决方法：
[root@cobbler cobbler]# vim /etc/cobbler/setting
378 # this is the address of the cobbler server -- as it is used
379 # by systems during the install process, it must be the address
380 # or hostname of the system as those systems can see the server.
381 # if you have a server that appears differently to different subnets
382 # (dual homed, etc), you need to read the --server-override section
383 # of the manpage for how that works.
384 server: 192.168.28.90 #将384行127.0.0.1修改为本机IP地址
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.
解决方法：
[root@cobbler cobbler]# vim /etc/cobbler/setting
269 # if using cobbler with manage_dhcp, put the IP address
270 # of the cobbler server here so that PXE booting guests can find it
271 # if you do not set this correctly, this will be manifested in TFTP open timeouts.
272 next_server: 192.168.28.90 #将272行127.0.0.1修改为本机IP地址，pxe服务器的IP，用Cobbler管理DHCP，所以填Cobbler服务器的IP
3 : change 'disable' to 'no' in /etc/xinetd.d/tftp
解决方法
[root@cobbler cobbler]# vim /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer \
# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware printers, \
# and to start the installation process for some operating systems.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no #将默认yes改为no
per_source = 11
cps = 100 2
flags = IPv4
}
4 : 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 : debmirror package is not installed, it will be required to manage debian deployments and repositories
解决办法：
提示说debmirror没安装
[root@cobbler cobbler]# yum install debmirror -y

解决办法：
