Scenario
- IPA cluster consists of 2 RHEL 6.6 servers
- Windows Server 2012 will be used for the Active Directory component
- IPA will manage a sub domain of the Active Directory domain (ipa.demo.net)
- IPA realm is (IPA)
- Active Directory domain is (demo.net)
- Active Directory realm is (WINDOWS)
- No existing DNS service is pre-existing
Using
- RHEL 6.6
- ipa-server 3.0.0
Build Master IPA Server
Fix the servers network identity
- /etc/sysconfig/network
- /etc/sysconfig/network-scripts/ifcfg-eth0
- /etc/resolv.conf (DNS to resolve Red Hat Satellite service)
- /etc/ntp.conf
- /etc/hosts (no existing DNS so add an entry for this host)
echo '192.168.1.53 ipa1.ipa.demo.net ipa1' >> /etc/hosts
Enable NTP
[root@ipa1 ~]# chkconfig ntpdate on
[root@ipa1 ~]# chkconfig ntpd on
Update software
[root@ipa1 ~]# yum update
Reboot
[root@ipa1 ~]# init 6
Log back in and make sure it is as you expect it to be:
[root@ipa1 ~]# hostname
[root@ipa1 ~]# ntpq -c lpeers
[root@ipa1 ~]# route -n
Install IPA
[root@ipa1 ~]# yum install ipa-server bind bind-dyndb-ldap
[root@ipa1 ~]# ipa-server-install --hostname=ipa1.ipa.demo.net -n ipa.demo.net -r IPA --setup-dns
The log file for this installation can be found in /var/log/ipaserver-install.log
==============================================================================
This program will set up the IPA Server.
This includes:
* Configure a stand-alone CA (dogtag) for certificate management
* 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)
* Configure DNS (bind)
To accept the default shown in brackets, press the Enter key.
Existing BIND configuration detected, overwrite? [no]: yes
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.

Warning: skipping DNS resolution of host ipa1.ipa.demo.net
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:
Password (confirm):
The IPA server requires an administrative user, named 'admin'.
This user is a regular system account used for IPA server administration.

==============================================================================
Setup complete
Next steps:
1. You must make sure these network ports are open:
TCP Ports:
* 80, 443: HTTP/HTTPS
* 389, 636: LDAP/LDAPS
* 88, 464: kerberos
* 53: bind
UDP Ports:
* 88, 464: kerberos
* 53: bind
* 123: ntp
2. You can now obtain a kerberos ticket using the command: 'kinit admin'
This ticket will allow you to use the IPA tools (e.g., ipa user-add)
and the web user interface.
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
Login and Test IPA Master
Ensure your web browser can resolve the fully-qualified host name of the ipa1 server. Even if this means adding an entry to the hosts file.
Point a web browser to:
https://ipa1.ipa.demo.net
Username: admin
Password: <as typed during installation>
Build Replica IPA Server
On the Master IPA Server
Prepare the initialisation file for the Replica:
[root@ipa1 ~]# ipa-replica-prepare ipa2.ipa.demo.net --ip-address 192.168.122.54
Directory Manager (existing master) password:
Preparing replica for ipa2.ipa.demo.net from ipa1.ipa.demo.net
Creating SSL certificate for the Directory Server
Creating SSL certificate for the dogtag Directory Server
Creating SSL certificate for the Web Server
Exporting RA certificate
Copying additional files
Finalizing configuration
Packaging replica information into /var/lib/ipa/replica-info-ipa2.ipa.demo.net.gpg
