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 FreeIPA サーバーを構築します。

[1] | FreeIPA をインストールします。 |
[root@dlp ~]# yum -y install ipa-server bind bind-dyndb-ldap
|
[2] | FreeIPA をセットアップします。 |
[root@dlp ~]# ipa-server-install --setup-dns The log file for this installation can be found in /var/log/ipaserver-install.log =========================================================== This program will set up the IPA Server. This includes: * Configure a stand-alone CA (dogtag) for certificate management * 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. # DNS を設定する (BIND の既存設定が上書きされる) Existing BIND configuration detected, overwrite? [no]: yes 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. # ホスト名を確認して Enter Server host name [dlp.srv.world]: The domain name has been determined based on the host name. # ドメイン名を確認して Enter Please confirm the domain name [srv.world]: The kerberos protocol requires a Realm name to be defined. This is typically the domain name converted to uppercase. # realm 名を確認、または変更して Enter Please provide a realm name [SRV.WORLD]: 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 のパスワード設定 Directory Manager password: Password (confirm): The IPA server requires an administrative user, named 'admin'. This user is a regular system account used for IPA server administration. # IPA admin のパスワード設定 IPA admin password: Password (confirm): # DNS forwarder を設定しない場合は no で応答 Do you want to configure DNS forwarders? [yes]: Enter the IP address of DNS forwarder to use, or press Enter to finish. # DNS forwarder を設定する場合、forwarder の IP を指定 Enter IP address for a DNS forwarder: 10.0.0.10 DNS forwarder 10.0.0.10 added # DNS forwarder を全て指定したら空Enter で応答 Enter IP address for a DNS forwarder: # 逆引きゾーンを設定しないなら no で応答 Do you want to configure the reverse zone? [yes]: # 逆引きゾーンを設定する場合のゾーン名 Please specify the reverse zone name [0.0.10.in-addr.arpa.]: The IPA Master Server will be configured with: Hostname: dlp.srv.world IP address: 10.0.0.30 Domain name: srv.world Realm name: SRV.WORLD BIND DNS server will be configured to serve IPA domain with: Forwarders: 10.0.0.10 Reverse zone: 0.0.10.in-addr.arpa. # 設定を確認して yes で進む Continue to configure the system with these values? [no]: yes The following operations may take some minutes to complete. Please wait until the prompt is returned. Configuring NTP daemon (ntpd) ... ... ... ========================================================== 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 |
