4.3 Configuration
4.3.1 check
[root@node01 yum.repos.d]# 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. # this is the address of the cobbler server -- as it is used # by systems during the install process, it must be the address # or hostname of the system as those systems can see the server. # if you have a server that appears differently to different subnets # (dual homed, etc), you need to read the --server-override section # of the manpage for how that works. >>server: 127.0.0.1 ==> server: 192.168.1.99 # Change the server to your IP 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. # if using cobbler with manage_dhcp, put the IP address # of the cobbler server here so that PXE booting guests can find it # if you do not set this correctly, this will be manifested in TFTP open timeouts. >>next_server: 127.0.0.1 ==> server: 192.168.1.99 3 : change 'disable' to 'no' in /etc/xinetd.d/tftp >>disable = yes ==> disable = no 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 ensu re 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. >> run command "cobbler get-loaders" 5 : enable and start rsyncd.service with systemctl >> rum command "systemctl enable rsyncd.service" 6 : debmirror package is not installed, it will be required to manage debian deployments and repositories >> Can be ignored. No package for CentOS 7. If you are using CentOS 6, try http://rpmfind.net/linux/rpm2html/search.php?query=debmirror 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: "o penssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one8 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them >> openssl passwd -1 -salt 'cobbler' 'Passw0rd' Restart cobblerd and then run 'cobbler sync' to apply changes.
