NAME
ipa-replica-install - Create an IPA replica
SYNOPSIS
DOMAIN LEVEL 0
ipa-replica-install [OPTION]... [replica_file]
DOMAIN LEVEL 1
ipa-replica-install [OPTION]...
DESCRIPTION
Configures a new IPA server that is a replica of the server. Once it has been created it is an exact copy
of the original IPA server and is an equal master. Changes made to any master are automatically
replicated to other masters.
To create a replica in a domain at domain level 0, you need to provide an replica file. The replica_file
is created using the ipa-replica-prepare utility.
To create a replica in a domain at domain level 1, you don't have to provide a replica file, the machine
only needs to be enrolled in the FreeIPA domain first. This process of turning the IPA client into a
replica is also referred to as replica promotion.
If you're starting with an existing IPA client, simply run ipa-replica-install to have it promoted into a
replica.
To promote a blank machine into a replica, you have two options, you can either run ipa-client-install in
a separate step, or pass the enrollment related options to the ipa-replica-install (see DOMAIN LEVEL 1
CLIENT ENROLLMENT OPTIONS). In the latter case, ipa-replica-install will join the machine to the IPA
realm automatically and will proceed with the promotion step.
If the installation fails you may need to run ipa-server-install --uninstall and ipa-client-install
before running ipa-replica-install again.
The installation will fail if the host you are installing the replica on exists as a host in IPA or an
existing replication agreement exists (for example, from a previously failed installation).
A replica should only be installed on the same or higher version of IPA on the remote system.
OPTIONS
DOMAIN LEVEL 1 OPTIONS
-P, --principal
The user principal which will be used to promote the client to the replica and enroll the client
itself, if necessary.
-w, --admin-password
The Kerberos password for the given principal.
DOMAIN LEVEL 1 CLIENT ENROLLMENT OPTIONS
To install client and promote it to replica using a host keytab or One Time Password, the host needs to
be a member of ipaservers group. This requires to create a host entry and add it to the host group prior
replica installation.
--server, --domain, --realm options are autodiscovered via DNS records by default. See manual page
ipa-client-install(1) for further details about these options.
-p PASSWORD, --password=PASSWORD
One Time Password for joining a machine to the IPA realm.
-k, --keytab
Path to host keytab.
--server
The fully qualified domain name of the IPA server to enroll to.
-n, --domain=DOMAIN
The primary DNS domain of an existing IPA deployment, e.g. example.com. This DNS domain should
contain the SRV records generated by the IPA server installer.
-r, --realm=REALM_NAME
The Kerberos realm of an existing IPA deployment.
--hostname
The hostname of this machine (FQDN). If specified, the hostname will be set and the system
configuration will be updated to persist over reboot.
--force-join
Join the host even if it is already enrolled.
DOMAIN LEVEL 0 OPTIONS
-p PASSWORD, --password=PASSWORD
Directory Manager (existing master) password
-w, --admin-password
Admin user Kerberos password used for connection check
BASIC OPTIONS
--ip-address=IP_ADDRESS
The IP address of this server. If this address does not match the address the host resolves to and
--setup-dns is not selected the installation will fail. If the server hostname is not resolvable,
a record for the hostname and IP_ADDRESS is added to /etc/hosts. This option can be used multiple
times to specify more IP addresses of the server (e.g. multihomed and/or dualstacked server).
--mkhomedir
Create home directories for users on their first login
--ntp-server=NTP_SERVER
Configure chronyd to use this NTP server. This option can be used multiple times and it is used to
specify exactly one time server.
--ntp-pool=NTP_SERVER_POOL
Configure chronyd to use this NTP server pool. This option is meant to be pool of multiple servers
resolved as one host name. This pool's servers may vary but pool address will be still same and
chrony will choose only one server from this pool.
-N, --no-ntp
Do not configure NTP client (chronyd).
--no-ui-redirect
Do not automatically redirect to the Web UI.
--ssh-trust-dns
Configure OpenSSH client to trust DNS SSHFP records.
--no-ssh
Do not configure OpenSSH client.
--no-sshd
Do not configure OpenSSH server.
--skip-conncheck
Skip connection check to remote master
-d, --debug
Enable debug logging when more verbose output is needed
-U, --unattended
An unattended installation that will never prompt for user input
--dirsrv-config-file
The path to LDIF file that will be used to modify configuration of dse.ldif during installation of
the directory server instance
CERTIFICATE SYSTEM OPTIONS
--setup-ca
Install and configure a CA on this replica. If a CA is not configured then certificate operations
will be forwarded to a master with a CA installed.
--no-pkinit
Disables pkinit setup steps. This is the default and only allowed behavior on domain level 0.
--dirsrv-cert-file=FILE
File containing the Directory Server SSL certificate and private key
--http-cert-file=FILE
File containing the Apache Server SSL certificate and private key
--pkinit-cert-file=FILE
File containing the Kerberos KDC SSL certificate and private key
--dirsrv-pin=PIN
The password to unlock the Directory Server private key
--http-pin=PIN
The password to unlock the Apache Server private key
--pkinit-pin=PIN
The password to unlock the Kerberos KDC private key
--dirsrv-cert-name=NAME
Name of the Directory Server SSL certificate to install
--http-cert-name=NAME
Name of the Apache Server SSL certificate to install
--pkinit-cert-name=NAME
Name of the Kerberos KDC SSL certificate to install
--skip-schema-check
Skip check for updated CA DS schema on the remote master
SECRET MANAGEMENT OPTIONS
--setup-kra
Install and configure a KRA on this replica. If a KRA is not configured then vault operations will
be forwarded to a master with a KRA installed.
DNS OPTIONS
--setup-dns
Configure an integrated DNS server, create a primary DNS zone (name specified by --domain or
taken from an existing deployment), and fill it with service records necessary for IPA deployment.
In cases where the IPA server name does not belong to the primary DNS domain and is not resolvable
using DNS, create a DNS zone containing the IPA server name as well.
This option requires that you either specify at least one DNS forwarder through the --forwarder
option or use the --no-forwarders option.
Note that you can set up a DNS at any time after the initial IPA server install by running ipa-
dns-install (see ipa-dns-install(1)). IPA DNS cannot be uninstalled.
--forwarder=IP_ADDRESS
Add a DNS forwarder to the DNS configuration. You can use this option multiple times to specify
more forwarders, but at least one must be provided, unless the --no-forwarders option is
specified.
--no-forwarders
Do not add any DNS forwarders. Root DNS servers will be used instead.
--auto-forwarders
Add DNS forwarders configured in /etc/resolv.conf to the list of forwarders used by IPA DNS.
--forward-policy=first|only
DNS forwarding policy for global forwarders specified using other options. Defaults to first if
no IP address belonging to a private or reserved ranges is detected on local interfaces (RFC
6303). Defaults to only if a private IP address is detected.
--reverse-zone=REVERSE_ZONE
The reverse DNS zone to use. This option can be used multiple times to specify multiple reverse
zones.
--no-reverse
Do not create new reverse DNS zone. If a reverse DNS zone already exists for the subnet, it will
be used.
--auto-reverse
Create necessary reverse zones
--allow-zone-overlap
Create DNS zone even if it already exists
--no-host-dns
Do not use DNS for hostname lookup during installation
--no-dns-sshfp
Do not automatically create DNS SSHFP records.
--no-dnssec-validation
Disable DNSSEC validation on this server.
AD TRUST OPTIONS
--setup-adtrust
Configure AD Trust capability on a replica.
--netbios-name=NETBIOS_NAME
The NetBIOS name for the IPA domain. If not provided then this is determined based on the leading
component of the DNS domain name. Running ipa-adtrust-install for a second time with a different
NetBIOS name will change the name. Please note that changing the NetBIOS name might break existing
trust relationships to other domains.
--add-sids
Add SIDs to existing users and groups as on of final steps of the ipa-adtrust-install run. If
there a many existing users and groups and a couple of replicas in the environment this operation
might lead to a high replication traffic and a performance degradation of all IPA servers in the
environment. To avoid this the SID generation can be run after ipa-adtrust-install is run and
scheduled independently. To start this task you have to load an edited version of ipa-sidgen-task-
run.ldif with the ldapmodify command info the directory server.
--add-agents
Add IPA masters to the list that allows to serve information about users from trusted forests.
Starting with FreeIPA 4.2, a regular IPA master can provide this information to SSSD clients. IPA
masters aren't added to the list automatically as restart of the LDAP service on each of them is
required. The host where ipa-adtrust-install is being run is added automatically.
Note that IPA masters where ipa-adtrust-install wasn't run, can serve information about users from
trusted forests only if they are enabled via ipa-adtrust-install run on any other IPA master. At
least SSSD version 1.13 on IPA master is required to be able to perform as a trust agent.
--rid-base=RID_BASE
First RID value of the local domain. The first Posix ID of the local domain will be assigned to
this RID, the second to RID+1 etc. See the online help of the idrange CLI for details.
--secondary-rid-base=SECONDARY_RID_BASE
Start value of the secondary RID range, which is only used in the case a user and a group share
numerically the same Posix ID. See the online help of the idrange CLI for details.
--enable-compat
Enables support for trusted domains users for old clients through Schema Compatibility plugin.
SSSD supports trusted domains natively starting with version 1.9. For platforms that lack SSSD or
run older SSSD version one needs to use this option. When enabled, slapi-nis package needs to be
installed and schema-compat-plugin will be configured to provide lookup of users and groups from
trusted domains via SSSD on IPA server. These users and groups will be available under
cn=users,cn=compat,$SUFFIX and cn=groups,cn=compat,$SUFFIX trees. SSSD will normalize names of
users and groups to lower case.
In addition to providing these users and groups through the compat tree, this option enables
authentication over LDAP for trusted domain users with DN under compat tree, i.e. using bind DN
uid=administrator@ad.domain,cn=users,cn=compat,$SUFFIX.
LDAP authentication performed by the compat tree is done via PAM 'system-auth' service. This
service exists by default on Linux systems and is provided by pam package as
/etc/pam.d/system-auth. If your IPA install does not have default HBAC rule 'allow_all' enabled,
then make sure to define in IPA special service called 'system-auth' and create an HBAC rule to
allow access to anyone to this rule on IPA masters.
As 'system-auth' PAM service is not used directly by any other application, it is safe to use it
for trusted domain users via compatibility path.
EXIT STATUS
0 if the command was successful
1 if an error occurred
3 if the host exists in the IPA server or a replication agreement to the remote master already exists
