FreeIPA : サーバーの設定2015/03/21 |
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 ipa-server-dns
|
[2] | FreeIPA をセットアップします。当例では FreeIPA サーバー上に同時に FreeIPA 内蔵 DNS もセットアップします。 |
# 自身のホスト名を hosts に登録 [root@dlp ~]# echo '10.0.0.30 dlp.ipa.srv.world dlp' >> /etc/hosts [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) * Configure DNS (bind) * Configure the KDC to enable PKINIT To accept the default shown in brackets, press the Enter key. WARNING: conflicting time&date synchronization service 'chronyd' will be disabled in favor of ntpd 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.ipa.srv.world]: Warning: skipping DNS resolution of host dlp.ipa.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 [ipa.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 [IPA.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): Checking DNS domain ipa.srv.world., please wait ... # DNS forwarder を設定しない場合は no で応答 Do you want to configure DNS forwarders? [yes]: Following DNS servers are configured in /etc/resolv.conf: 10.0.0.10 # DNS forwarder を設定する場合 且つ resolv.conf と同設定で OK ではない場合は no で応答 Do you want to configure these servers as DNS forwarders? [yes]: All DNS servers from /etc/resolv.conf were added. You can enter additional addresses now: Enter an IP address for a DNS forwarder, or press Enter to skip: Checking DNS forwarders, please wait ... DNS server 10.0.0.10: answer to query '. SOA' is missing DNSSEC signatures (no RRSIG data) Please fix forwarder configuration to enable DNSSEC support. (For BIND 9 add directive "dnssec-enable yes;" to "options {}") WARNING: DNSSEC validation will be disabled Do you want to search for missing reverse zones? [yes]: The IPA Master Server will be configured with: Hostname: dlp.ipa.srv.world IP address(es): 10.0.0.30 Domain name: ipa.srv.world Realm name: IPA.SRV.WORLD BIND DNS server will be configured to serve IPA domain with: Forwarders: 10.0.0.10 Forward policy: only Reverse zone(s): No reverse zone # 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) [1/4]: stopping ntpd [2/4]: writing configuration [3/4]: configuring ntpd to start on boot [4/4]: starting ntpd Done configuring NTP daemon (ntpd). Configuring directory server (dirsrv). Estimated time: 30 seconds [1/45]: creating directory server instance [2/45]: enabling ldapi [3/45]: configure autobind for root ..... ..... Client configuration complete. The ipa-client-install command was successful ============================================================================== 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 * 53: bind UDP Ports: * 88, 464: kerberos * 53: bind * 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 certificates stored in /root/cacert.p12 These files are required to create replicas. The password for these files is the Directory Manager password |
[3] | Kerberos チケットを取得し、デフォルトシェルを明示的に bash に変更しておきます。 |

[4] | Firewalld を有効にしている場合は FreeIPA サービス、および内蔵 DNS を使用している場合は DNS サービスの許可が必要です。 |
[root@dlp ~]# firewall-cmd --add-service={freeipa-ldap,freeipa-ldaps,dns,ntp} --permanent success [root@dlp ~]# firewall-cmd --reload success |
