RedHat搭建IPA-Server

ipa-server是红帽身份验证的一个完整解决方案，上游的开源项目是freeIPA，它本身不提供具体功能，而是整合了389-ds、ipa-server-dns、krb5-server等核心软件包，形成一个以389-ds（ldap）为数据存储后端，krb5-server为验证前端，ipa-server-dns为主机识别，apache+tomcat提供的一个web管理界面，统一的命令行管理界面的身份识别系统。

存储的是主机名（域名）、IP地址、用户名、密码等，以读为主，因此非常适合ldap的特性。

RedHat搭建IPA-Server

验证服务: Kerberos KDC
存储服务: Red Hat Directory Server
证书系统: Red Hat Certificate System
域名解析服务: DNS
安全管理服务: SSSD
时间同步服务: NTP

Servers Servers manage all of the services used by domain members.

Replicas Replica are copies of servers. Once a replica is installed, it is functionally identical to a server.

Clients Clients, which belong to the Kerberos domains, receive certificates and tickets issued by the servers, and use other centralized services for authentication and authorization.

IPA-Server

设置机器名

# hostnamectl set-hostname ipa.example.com

开放防火墙端口

# firewall-cmd --permanent --add-port={80/tcp,443/tcp,389/tcp,636/tcp,88/tcp,464/tcp,53/tcp,88/udp,464/udp,53/udp,123/udp}

# firewall-cmd --reload

安装软件包

# yum install ipa-server ipa-server-dns

ipa-server-install参数

--hostname=host name

-r realm_name

-n domain_name

--subject=subject_DN

-a ipa_admin_password

-p directory_manager_password

-P kerberos_master_password

--idmax=number

--idstart=number

--ip-address

--setup-dns

--forwarder=forwarder

--no-forwarders

--no-reverse

安装IPA Server

# ipa-server-install --hostname ipa.example.com --ip-address=192.168.136.251 \

--setup-dns --forwarder=192.168.136.2 \

-r EXAMPLE.COM -n EXAMPLE.COM \

-p DM_password -a admin_password

注：

DM_password 是kerberos的管理员密码

admin_password 是389-ds的管理员密码

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)

卸载IPA Server

# ipa-server-install --uninstall

IPA-Replica

设置机器名

# hostnamectl set-hostname replica.example.com

开放防火墙端口

# firewall-cmd --permanent --add-port={80/tcp,443/tcp,389/tcp,636/tcp,88/tcp,464/tcp,53/tcp,88/udp,464/udp,53/udp,123/udp}

# firewall-cmd --reload

安装软件包

# yum install ipa-server ipa-server-dns

生成gpg文件

在IPA Server上运行

# ipa-replica-prepare replica.example.com --ip-address 192.168.136.252

# scp /var/lib/ipa/replica-info-replica.example.com.gpg root@replica:/var/lib/ipa/

安装IPA Replica

# ipa-replica-install /var/lib/ipa/replica-info-replica.example.com.gpg \
--setup-dns --forwarder 192.168.136.2 \
-p DM_password -w admin_password

测试IPA Replica

# ipa user-add test_user --first=Test --last=User
# ipa user-show test_user

卸载IPA Replica

# ipa-replica-manage del replica.example.com

# ipa-server-install --uninstall

IPA-Client

设置机器名

# hostnamectl set-hostname client1.example.com

开放防火墙端口

# firewall-cmd --permanent --add-port={80/tcp,443/tcp,389/tcp,636/tcp,88/tcp,464/tcp,53/tcp,88/udp,464/udp,53/udp,123/udp}

# firewall-cmd --reload

安装软件包

# yum install ipa-client

安装IPA Client

# ipa-client-install --enable-dns-updates --domain EXAMPLE.COM --mkhomedir --no-ntp -p admin

IPA 管理

服务管理

# ipactl start|stop|restart|status （IPA服务启动，停止，重启，状态）

用户管理

添加用户

# ipa user-add jsmith

修改用户

# ipa user-mod jsmith --title="Editor III"

删除用户

# ipa user-del jsmith
查找用户
# ipa user-find smith
