FreeIPA : サーバーの設定2018/11/27 |
|
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:~# apt -y install freeipa-server freeipa-server-dns
# レルム名を指定 +------------------+ Configuring Kerberos Authentication +------------------+ | When users attempt to use Kerberos and specify a principal or user name | | without specifying what administrative Kerberos realm that principal | | belongs to, the system appends the default realm. The default realm may | | also be used as the realm of a Kerberos service running on the local | | machine. Often, the default realm is the uppercase version of the local | | DNS domain. | | | | Default Kerberos version 5 realm: | | | | IPA.SRV.WORLD____________________________________________________________ | | | | <Ok> | | | +---------------------------------------------------------------------------+ # FreeIPAサーバーのホスト名を指定 +-----------------+ Configuring Kerberos Authentication +-----------------+ | Enter the hostnames of Kerberos servers in the IPA.SRV.WORLD Kerberos | | realm separated by spaces. | | | | Kerberos servers for your realm: | | | | dlp.ipa.srv.world______________________________________________________ | | | | <Ok> | | | +-------------------------------------------------------------------------+ # FreeIPAサーバーのホスト名を指定 +------------------+ Configuring Kerberos Authentication +------------------+ | Enter the hostname of the administrative (password changing) server for | | the IPA.SRV.WORLD Kerberos realm. | | | | Administrative server for your Kerberos realm: | | | | dlp.ipa.srv.world________________________________________________________ | | | | <Ok> | | | +---------------------------------------------------------------------------+ |
| [2] | FreeIPA サーバーをセットアップします。当例では FreeIPA サーバー上には同時に内蔵 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
# KDC DB 初期化 root@dlp:~# kdb5_util create -s -r IPA.SRV.WORLD
Loading random data
Initializing database '/var/lib/krb5kdc/principal' for realm 'IPA.SRV.WORLD',
master key name 'K/M@IPA.SRV.WORLD'
# 任意の DB パスワードを設定
You will be prompted for the database Master Password.
It is important that you NOT FORGET this password.
Enter KDC database master key:
Re-enter KDC database master key to verify:
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 FreeIPA 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 フォワーダーを設定する場合は yes Do you want to configure DNS forwarders? [yes]: no No DNS forwarders configured # リバースゾーン検索する場合は yes Do you want to search for missing reverse zones? [yes]: 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 The CA will be configured with: Subject DN: CN=Certificate Authority,O=IPA.SRV.WORLD Subject base: O=IPA.SRV.WORLD Chaining: self-signed BIND DNS server will be configured to serve IPA domain with: Forwarders: No forwarders 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) ..... ..... ..... ============================================================================== 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 passwordroot@dlp:~# chmod 755 /var/lib/krb5kdc root@dlp:~# touch /var/log/kadmind.log /etc/krb5kdc/kadm5.acl root@dlp:~# systemctl restart krb5-admin-server |
| [3] | Kerberos チケットを取得しておきます。また、デフォルトシェルを Bash に変更しておきます。 |
