IPAサーバー構築2011/11/20 |
|
各サーバー間でユーザーのアカウント情報を共有できるようにIPAサーバーを構築します。
設定するホストはDNSで正引き/逆引きが正常にできるようにしておいてください。

| [1] | FreeIPAインストール |
|
[root@master ~]#
vi /etc/hosts # 自身のIPアドレスとホスト名を登録しておく 10.0.0.100 master.srv.world master
[root@master ~]#
[root@master ~]# yum -y install ipa-server ipa-server-install # セットアップ The log file for this installation can be found in /var/log/ipaserver-install.log ============================================================================== This program will set up the FreeIPA Server. This includes: * Configure the Network Time Daemon (ntpd) * Create and configure an instance of Directory Server * Create and configure a Kerberos Key Distribution Center (KDC) * Configure Apache (httpd) To accept the default shown in brackets, press the Enter key. Enter the fully qualified domain name of the computer on which you're setting up server software. Using the form <hostname>.<domainname> Example: master.example.com.Server host name [master.srv.world]: # ホスト名を確認してEnter
The domain name has been calculated based on the host name.
Please confirm the domain name [srv.world]:
# ドメイン名を確認してEnter The IPA Master Server will be configured with Hostname: master.srv.world IP address: 10.0.0.100 Domain name: srv.world The kerberos protocol requires a Realm name to be defined. This is typically the domain name converted to uppercase.Please provide a realm name [SRV.WORLD]: # realm名を確認してEnter
Certain directory server operations require an administrative user.
This user is referred to as the Directory Manager and has full access
to the Directory for system management tasks and will be added to the
instance of directory server created for IPA.
The password must be at least 8 characters long.
Directory Manager password:
# Directory Manager のパスワード設定 Password (confirm): # 確認再入力
The IPA server requires an administrative user, named 'admin'.
This user is a regular system account used for IPA server administration.
IPA admin password:
# IPA admin のパスワード設定 Password (confirm): # 確認再入力
The following operations may take some minutes to complete.
Please wait until the prompt is returned.

==============================================================================
Setup complete
Next steps:
1. You must make sure these network ports are open:
TCP Ports:
* 80, 443: HTTP/HTTPS
* 389, 636: LDAP/LDAPS
* 88, 464: kerberos
UDP Ports:
* 88, 464: kerberos
* 123: ntp
2. You can now obtain a kerberos ticket using the command: 'kinit admin'
This ticket will allow you to use the IPA tools (e.g., ipa user-add)
and the web user interface.
Be sure to back up the CA certificate stored in /root/cacert.p12
This file is required to create replicas. The password for this
file is the Directory Manager password

| [2] | Kerberos チケットを取得し、デフォルトシェルを bash に変更しておきます。また ntp の参照先が変更されているので元に戻しておきます。 |
