ipa-server-install - Configure an IPA server
SYNOPSIS
ipa-server-install [OPTION]...
DESCRIPTION
Configures the services needed by an IPA server. This includes setting up a Kerberos Key Distribution Center (KDC) and a Kadmin daemon with
an LDAP back-end, configuring Apache, configuring NTP and optionally configuring and starting an LDAP-backed DNS server. By default a dog-
tag-based CA will be configured to issue server certificates.
OPTIONS
BASIC OPTIONS
-r REALM_NAME, --realm=REALM_NAME
The Kerberos realm name for the IPA server. You will not be able to estabilish trust with Active Directory unless the realm name is
uppercased domain name.
-n DOMAIN_NAME, --domain=DOMAIN_NAME
Your DNS domain name
-p DM_PASSWORD, --ds-password=DM_PASSWORD
The password to be used by the Directory Server for the Directory Manager user
-P MASTER_PASSWORD, --master-password=MASTER_PASSWORD
The kerberos master password (normally autogenerated)
-a ADMIN_PASSWORD, --admin-password=ADMIN_PASSWORD
The password for the IPA admin user
--mkhomedir
Create home directories for users on their first login
--hostname=HOST_NAME
The fully-qualified DNS name of this server. If the hostname does not match system hostname, the system hostname will be updated
accordingly to prevent service failures.
--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.
-N, --no-ntp
Do not configure NTP
--idstart=IDSTART
The starting user and group id number (default random)
--idmax=IDMAX
The maximum user and group id number (default: idstart+199999). If set to zero, the default value will be used.
--no_hbac_allow
Don't install allow_all HBAC rule. This rule lets any user from any host access any service on any other host. It is expected that
users will remove this rule before moving to production.
--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.
-d, --debug
Enable debug logging when more verbose output is needed
-U, --unattended
An unattended installation that will never prompt for user input
CERTIFICATE SYSTEM OPTIONS
--external-ca
Generate a CSR to be signed by an external CA
--external_cert_file=FILE
PEM file containing a certificate signed by the external CA. Must be given with --external_ca_file.
--external_ca_file=FILE
PEM file containing the external CA chain
--dirsrv_pkcs12=FILE
PKCS#12 file containing the Directory Server SSL Certificate
--http_pkcs12=FILE
PKCS#12 file containing the Apache Server SSL Certificate
--dirsrv_pin=DIRSRV_PIN
The password of the Directory Server PKCS#12 file
--http_pin=HTTP_PIN
The password of the Apache Server PKCS#12 file
--subject=SUBJECT
The certificate subject base (default O=REALM.NAME)
DNS OPTIONS
--setup-dns
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.
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)).
--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.
--reverse-zone=REVERSE_ZONE
The reverse DNS zone to use
--no-reverse
Do not create reverse DNS zone
--zonemgr
The e-mail address of the DNS zone manager. Defaults to hostmaster@DOMAIN
--no-host-dns
Do not use DNS for hostname lookup during installation
--no-dns-sshfp
Do not automatically create DNS SSHFP records.
UNINSTALL OPTIONS
--uninstall
Uninstall an existing IPA installation
-U, --unattended

EXIT STATUS
