红帽全球峰会15.2. Kickstart file for client installation
You can use a Kickstart file to install an Identity Management (IdM) client. The contents of the Kickstart file must meet certain requirements as outlined here.
- The
ipa-clientpackage in the list of packages to install Add the
ipa-clientpackage to the %packages section of the Kickstart file. For example:%packages ... ipa-client ...- Post-installation instructions for the IdM client
The post-installation instructions must include:
- An instruction for ensuring SSH keys are generated before enrollment
An instruction to run the
ipa-client-installutility, while specifying:- All the required information to access and configure the IdM domain services
- The password which you set when pre-creating the client host on the IdM server. in 第 15.1 节 “Installing a client with Kickstart”.
For example, the post-installation instructions for a Kickstart installation that uses a one-time password and retrieves the required options from the command line rather than via DNS can look like this:
%post --log=/root/ks-post.log # Generate SSH keys; ipa-client-install uploads them to the IdM server by default /usr/libexec/openssh/sshd-keygen rsa # Run the client install script /usr/sbin/ipa-client-install --hostname=client.example.com --domain=EXAMPLE.COM --enable-dns-updates --mkhomedir -w secret --realm=EXAMPLE.COM --server=server.example.com
Optionally, you can also include other options in the Kickstart file, such as:
-
For a non-interactive installation, add the
--unattendedoption toipa-client-install. To let the client installation script request a certificate for the machine:
-
Add the
--request-certoption toipa-client-install. Set the system bus address to
/dev/nullfor both thegetcertandipa-client-installutility in the Kickstartchrootenvironment. To do this, add these lines to the post-installation instructions in the Kickstart file before theipa-client-installinstruction:# env DBUS_SYSTEM_BUS_ADDRESS=unix:path=/dev/null getcert list # env DBUS_SYSTEM_BUS_ADDRESS=unix:path=/dev/null ipa-client-install
-
