ipa-replica-install — Create an IPA replica


Domain Level 0

ipa-replica-install [OPTION]... [replica_file]

Domain Level 1

ipa-replica-install [OPTION]...


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.


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.

-p PASSWORD, --password=PASSWORD

One Time Password for joining a machine to the IPA realm.

-k, --keytab

Path to host keytab.


The fully qualified domain name of the IPA server to enroll to.

-n, --domain=DOMAIN

Set the domain name to DOMAIN.

-r, --realm=REALM_NAME

Set the IPA realm name to REALM_NAME.


The hostname of this machine (FQDN). If specified, the hostname will be set and the system configuration will be updated to persist over reboot.

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


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 this option can be used multiple times to specify more IP addresses of the server (e.g. multihomed and/or dualstacked server).


Create home directories for users on their first login

-N, --no-ntp

Do not configure NTP


Do not automatically redirect to the Web UI.


Configure OpenSSH client to trust DNS SSHFP records.


Do not configure OpenSSH client.


Do not configure OpenSSH server.


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


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


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.


Disables pkinit setup steps


File containing the Directory Server SSL certificate and private key


File containing the Apache Server SSL certificate and private key


File containing the Kerberos KDC SSL certificate and private key


The password to unlock the Directory Server private key


The password to unlock the Apache Server private key


The password to unlock the Kerberos KDC private key


Name of the Directory Server SSL certificate to install


Name of the Apache Server SSL certificate to install


Name of the Kerberos KDC SSL certificate to install


Skip check for updated CA DS schema on the remote master

DNS Options


Generate a DNS zone if it does not exist already and configure the DNS server. This option requires that you either specify at least one DNS forwarder through the --forwarder option or use the --no-forwarders option.


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.


Do not add any DNS forwarders. Root DNS servers will be used instead.


Add DNS forwarders configured in /etc/resolv.conf to the list of forwarders used by IPA DNS.


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.


The reverse DNS zone to use. This option can be used multiple times to specify multiple reverse zones.


Do not create new reverse DNS zone. If a reverse DNS zone already exists for the subnet, it will be used.


Create necessary reverse zones


Create DNS zone even if it already exists


Do not use DNS for hostname lookup during installation


Do not automatically create DNS SSHFP records.


Disable DNSSEC validation on this server.

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
