Select Install a new system or upgrade an existing system :. I assume that you use a locally attached hard drive, so you should select Basic Storage Devices here:.
As we want a fresh Fedora installation, click on the Yes, discard any data button next:. Next we do the partitioning. Select Replace Existing Linux System s. Now we select the software we want to install. Uncheck Graphical Desktop and check Web Server instead. Then check Customize now. As the last two repositories need an Internet connection, a new window pops up where you have to configure your network card.
Select your network card and click on OK :. Mark the Connect automatically checkbox and go to the IPv4 Settings tab and select Manual in the Method drop-down menu. Nameserver Zones. The resource record is usually a fully qualified domain name FQDN of a host, and is broken down into multiple sections organized into a tree-like hierarchy. This hierarchy consists of a main trunk, primary branches, secondary branches, and so on. The following is an example of a resource record:.
Each level of the hierarchy is divided by a period that is,. In the example above, com defines the top-level domain , example its subdomain, and sales the subdomain of example. In this case, bob identifies a resource record that is part of the sales. With the exception of the part furthest to the left that is, bob , each of these sections is called a zone and defines a specific namespace. Zones are defined on authoritative nameservers through the use of zone files , which contain definitions of the resource records in each zone.
Zone files are stored on primary nameservers also called master nameservers , where changes are made to the files, and secondary nameservers also called slave nameservers , which receive zone definitions from the primary nameservers. Both primary and secondary nameservers are authoritative for the zone and look the same to clients.
Depending on the configuration, any nameserver can also serve as a primary or secondary server for multiple zones at the same time. Nameserver Types. This category includes both primary master and secondary slave nameservers. Hostname Requirements. The hostname must be a fully-qualified domain name. For example, ipaserver. This must be a valid DNS name, which means only numbers, alphabetic characters, and hyphens - are allowed.
Other characters, like underscores, in the hostname will cause DNS failures. The server's machine name must be set and resolve to its public IP address. The fully-qualified domain name cannot resolve to the loopback address.
It must resolve to the machine's public IP address, not to The output of the hostname command cannot be localhost or localhost6. The reverse of the address that the hostname resolves to must match the hostname. The DNS must be correctly configured to resolve forward and reverse addresses. Directory Server. There must not be any instances of Directory Server installed on the host machine.
System Files. The server script overwrites system files to set up the FreeIPA domain. System Ports. FreeIPA uses a number of ports to communicate with its services. These ports, listed in Table 2. They cannot be in use by another service or blocked by a firewall.
To make sure that these ports are available, try iptables to list the available ports or nc , telnet , or nmap to connect to a port or run a port scan. The iptables man page has more information on opening and closing ports on a system. If a server is being installed on a virtual machine, that server should not run an NTP server. During the installation, FreeIPA displays a message similar to the following:. COM realm:. The nscd service is extremely useful for reducing the load on the server, and for making clients more responsive, but there can be problems when a system is also using SSSD, which performs its own caching.
Because nscd performs both positive and negative caching, if a request determines that a specific FreeIPA user does not exist, it marks this as a negative cache.
