[root@dlp ~]#
vi /etc/hosts # add own IP address and hostname 10.0.0.30 dlp.srv.world dlp
[root@dlp ~]#
[root@dlp ~]# yum -y install freeipa-server ipa-server-install # setup The log file for this installation can be found in /var/log/ipaserver-install.log ============================================================================== This program will set up the FreeIPA Server. This includes: * Configure the Network Time Daemon (ntpd) * Create and configure an instance of Directory Server * Create and configure a Kerberos Key Distribution Center (KDC) * Configure Apache (httpd) To accept the default shown in brackets, press the Enter key. Enter the fully qualified domain name of the computer on which you're setting up server software. Using the form <hostname>.<domainname> Example: master.example.com.Server host name [dlp.srv.world]: # Enter if hostname is OK
The domain name has been calculated based on the host name.
Please confirm the domain name [srv.world]:
# Enter if domainname is OK The kerberos protocol requires a Realm name to be defined. This is typically the domain name converted to uppercase.Please provide a realm name [SRV.WORLD]: # Enter if realm is OK
Certain directory server operations require an administrative user.
This user is referred to as the Directory Manager and has full access
to the Directory for system management tasks and will be added to the
instance of directory server created for IPA.
The password must be at least 8 characters long.
Directory Manager password:
# set Directory Manager's password Password (confirm): # confirm
The IPA server requires an administrative user, named 'admin'.
This user is a regular system account used for IPA server administration.
IPA admin password:
# set IPA admin's password Password (confirm): # confirm The IPA Master Server will be configured with: Hostname: dlp.srv.world IP address: 10.0.0.30 Domain name: srv.world Realm name: SRV.WORLDContinue to configure the system with these values? [no]: yes # Yes *** *** Be sure to back up the CA certificate stored in /root/cacert.p12 This file is required to create replicas. The password for this file is the Directory Manager password |
| [2] | Get Kerberos ticket and change default shell to bash. Furthermore, restore NTP settings because it was changed. |
