CentOS部署FreeIPA Server和FreeIPA Client

FreeIPA是针对Linux/UNIX网络环境的统一身份验证和访问控制解决方案,详细的介绍你可以参考官网

本文将在CentOS 7下部署FreeIPA Server,我曾尝试在CentOS 8下面部署FreeIPA Server,但是很不幸,各种错误源源不断,并无法解决,无奈只能在CentOS 7下面部署,且非常顺利,FreeIPA Client将在CentOS 8下部署。

环境

主域我们将会使用corp.ansheng.me

主机名 内部IP 外部IP 系统 描述
ipa.corp.ansheng.me 10.170.0.41 34.92.40.93 CentOS 7 服务端
client.corp.ansheng.me 10.170.0.42 35.220.235.42 CentOS 8 客户端

下面是每个机器的初始化操作,主要执行以下操作

  1. 关闭SELINUX
  2. 设置主机名
  3. 更新系统
  4. 添加hosts解析或者设置DNS

FreeIPA Server

$ whoami
root
$ free -h
              total        used        free      shared  buff/cache   available
Mem:           3.7G        196M        3.3G        8.4M        171M        3.3G
Swap:            0B          0B          0B
$ cat /proc/cpuinfo | grep processor | wc -l
2
$ sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config
$ setenforce 0
$ hostnamectl set-hostname ipa.corp.ansheng.me
$ yum update -y
$ reboot
$ cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

如果你用的是GCP,在重启之后hostname会恢复成原来的样子,所以你需要再次执行下面的指令

$ hostnamectl set-hostname ipa.corp.ansheng.me
$ hostname
ipa.corp.ansheng.me

添加HOSTS解析

$ vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.170.0.41 ipa.corp.ansheng.me ipa # 要放在127下面,并在其他host记录前面
........

FreeIPA Client

$ whoami
root
$ free -h
              total        used        free      shared  buff/cache   available
Mem:          818Mi       231Mi       283Mi       5.0Mi       303Mi       464Mi
Swap:            0B          0B          0B
$ cat /proc/cpuinfo | grep processor | wc -l
2
$ sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config
$ setenforce 0
$ hostnamectl set-hostname client.corp.ansheng.me
$ dnf update -y
$ reboot
$ cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)

如果你用的是GCP,在重启之后hostname会恢复成原来的样子,所以你需要再次执行下面的指令

$ hostnamectl set-hostname client.corp.ansheng.me
$ hostname
client.corp.ansheng.me

在部署之前,我建议你先看一下FreeIPA官方的部署建议

FreeIPA Server

安装所需要的软件包

$ yum install ipa-server ipa-server-dns -y

初始化

$ ipa-server-install \
  -r CORP.ANSHENG.ME \
  --mkhomedir \
  --setup-dns \
  --forwarder=8.8.8.8 \
  --forwarder=1.1.1.1 \
  --no-dnssec-validation \
  --ds-password ds-password \
  --admin-password admin-password
选项 描述
-r CORP.ANSHENG.ME 主域,大写
--mkhomedir 用户首次登录自动创建家目录
--setup-dns 配置DNS
--forwarder=8.8.8.8 上游DNS1
--forwarder=1.1.1.1 上游DNS2
--no-dnssec-validation 禁用dnssec验证
--ds-password ds-password 目录管理员密码
--admin-password admin-password 管理员用户密码

下面是执行ipa-server-install之后输出的log

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.

Server host name [ipa.corp.ansheng.me]: # 回车

Warning: skipping DNS resolution of host ipa.corp.ansheng.me
The domain name has been determined based on the host name.

Please confirm the domain name [corp.ansheng.me]: # 回车

Checking DNS domain corp.ansheng.me., please wait ...
Do you want to search for missing reverse zones? [yes]: # 回车

The IPA Master Server will be configured with:
Hostname:       ipa.corp.ansheng.me
IP address(es): 10.170.0.41
Domain name:    corp.ansheng.me
Realm name:     CORP.ANSHENG.ME

BIND DNS server will be configured to serve IPA domain with:
Forwarders:       8.8.8.8, 1.1.1.1
Forward policy:   only
Reverse zone(s):  No reverse zone

WARNING: Realm name does not match the domain name.
You will not be able to establish trusts with Active Directory unless
the realm name of the IPA server matches its domain name.

Continue to configure the system with these values? [no]: yes # yes

==============================================================================
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

安装的速度取决于你的机器配置,我尝试过在1GB内存的机器上面安装会失败,调整到4GB就可以了,2GB没测试。

  • 开放端口

上面安装完成之后我们需要开放一些端口才能够进行正常的访问,如果你的防火墙已经disable了,则可以跳过这一步,否则请执行下面的指令

$ firewall-cmd --add-service={http,https,freeipa-ldap,freeipa-ldaps,dns,ntp,kerberos} --permanent
success
$ firewall-cmd --reload
success
$ firewall-cmd --list-all

如果你可以成功通过SSH连接到ansheng@ipa.corp.ansheng.me,则说明FreeIPA Server已经配置完成。

  • Web UI

FreeIPA还为我们提供了非常好用的UI界面,如果要使用,请在本地hosts文件下添加一条解析记录

$ sudo vim /etc/hosts
......

$ ping -c 3 ipa.corp.ansheng.me

通过浏览器打开ipa.corp.ansheng.me这个地址,由于FreeIPA使用的是自签名证书,所以浏览器会提示SSL错误,不过没关系,我们跳过即可

1605769312

进入登陆界面,输入账号admin和密码admin-password

1605769341

这就是FreeIPA的WebUI了,里面有很多功能,大家慢慢研究

1605769353

FreeIPA Client

首先我们需要把DNS改为FreeIPA Server的地址,因为都在同一个内网,所以我们只需要填内网的地址就即可

$ vi /etc/resolv.conf
# Generated by NetworkManager
search asia-east2-a.c.rosy-algebra-275509.internal c.rosy-algebra-275509.internal google.internal corp.ansheng.me
nameserver 10.170.0.41  # 把FreeIPA Server DNS写在前面
nameserver 169.254.169.254

然后通过ping测试看看能否解析

$ ping -c 5 ipa.corp.ansheng.me
PING ipa.corp.ansheng.me (10.170.0.41) 56(84) bytes of data.
64 bytes from 10.170.0.41 (10.170.0.41): icmp_seq=1 ttl=64 time=1.44 ms

$ dnf distro-sync -y
$ dnf install ipa-client -y
