CentOS安装配置freeIPA
FreeIPA是Linux开源安全解决方案，提供用户账户管理和集中身份验证。
FreeIPA在CentOS 7、Fedora和Ubuntu14.04 /16.04上能够非常直接地将计算机添加到您的IPA域中。其他操作系统可以使用SSSD或LDAP对FreeIPA进行身份验证。
freeIPA的部署：
1、设置主机名：
hostnamectl set-hostname ipaserver.changchunhua.cloud2、升级软件和系统内核：
yum update -y3、设置防火墙：
systemctl stop firewalld && systemctl disable firewalld4、配置hosts文件：
vim /etc/hosts
192.168.17.120 ipaserver.changchunhua.cloud ipaserver5、配置随机数生成器：
yum install -y rng-tools
systemctl start rngd
systemctl enable rngd
systemctl status rngd6、安装Bind软件并启动：
yum -y install bind bind-utils bind-dyndb-ldap
systemctl start named
systemctl enable named
systemctl status named
vim /etc/resolv.conf
nameserver 127.0.0.17、安装ipa-server软件包：
yum -y install ipa-server ipa-server-dns8、配置ipa-server:
[root@ipaserver ~]# ipa-server-install --allow-zone-overlap
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 the KDC to enable PKINIT
To accept the default shown in brackets, press the Enter key.

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
9、验证freeIPA服务功能
通过尝试为admin用户初始化kerberos令牌来验证Kerberos域是否已正确安装。
[root@vm1 ~]# kinit admin
Password for [email protected]:
[root@ipaserver ~]# klist
Ticket cache: KEYRING:persistent:0:0
Default principal: [email protected]
Valid starting Expires Service principal
11/12/2022 02:32:36 11/13/2022 02:32:33 krbtgt/[email protected]
10、验证IPA服务器是否正常运行
[root@ipaserver ~]# ipa user-find admin
--------------
1 user matched
--------------
User login: admin
Last name: Administrator
Home directory: /home/admin
Login shell: /bin/bash
Principal alias: [email protected]
UID: 229800000
GID: 229800000
Account disabled: False
----------------------------
Number of entries returned 1
----------------------------
然后我这边通过浏览器访问https://ipaserver.changchunhua.cloud/ipa/ui出现问题。
这个问题，我估计是什么DNS的问题。更新了电脑上的DNS的配置。
然后就能看到这个页面了。
通过ping命令，可以解析成功。
使用admin的账号和配置的密码登录：
11、查看IPA组件状态：
[root@ipaserver ~]# ipactl status
Directory Service: RUNNING
krb5kdc Service: RUNNING
kadmin Service: RUNNING
named Service: RUNNING
httpd Service: RUNNING
ipa-custodia Service: RUNNING
ntpd Service: RUNNING
pki-tomcatd Service: RUNNING
ipa-otpd Service: RUNNING
ipa-dnskeysyncd Service: RUNNING
ipa: INFO: The ipactl command was successful
[root@ipaserver ~]# ipactl --help
Usage: ipactl start|stop|restart|status
Options:
-h, --help show this help message and exit
-d, --debug Display debugging information
-f, --force Force IPA to start. Combine options --skip-version-
check and --ignore-service-failures
--ignore-service-failures
If any service start fails, do not rollback the
services, continue with the operation
--skip-version-check skip version check
2023年3月6日：
然后我这边再试着按照docker的方式来部署freeIPA：
docker run --rm --name freeipa -ti \
--read-only \
--sysctl net.ipv6.conf.all.disable_ipv6=0 \
-h ipaserver.changchunhua.cloud \
-p 443:443 -p 8009:389 \
-v /sys/fs/cgroup:/sys/fs/cgroup:ro \
-v /data/webapps/ipa:/data:Z \
freeipa/freeipa-server:centos-8-stream
