How to Install FreeIPA Server on RHEL 8 | Rocky Linux 8 | AlmaLinux 8
|
||||
======
|
||||
|
||||
Are you looking for an easy guide on how to install FreeIPA server on Linux ?
|
||||
|
||||
The step-by-step guide on this page will show how to install FreeIPA server on RHEL 8 , Rocky Linux 8 and AlmaLinux 8.
|
||||
|
||||
[FreeIPA][1]is a free and open source centralized identity and access management tool for Linux-based systems, it is the upstream project for Red Hat identity manager. Using FreeIPA, we can easily manage centralized authentication along with account management, policy (host-based access control) and audit.
|
||||
|
||||
FreeIPA is based on the following Open Source projects,
|
||||
|
||||
- LDAP Server – based on the 389 project
|
||||
- KDC – based on MIT Kerberos implementation
|
||||
- PKI based on Dogtag project
|
||||
- Samba libraries for Active Directory integration
|
||||
- DNS Server based on BIND and the Bind-DynDB-LDAP plugin
|
||||
- NTP
|
||||
|
||||
##### Prerequisites
|
||||
|
||||
- Pre Installed RHEL 8 or Rocky Linux 8 or AlmaLinux 8
|
||||
- Sudo User with admin rights
|
||||
- RAM = 2 GB
|
||||
- CPU =2 vCPU
|
||||
- Disk = 12 GB free space on /
|
||||
- Internet connectivity
|
||||
|
||||
##### Lab Details for FreeIPA
|
||||
|
||||
- IP Address = 192.168.1.102
|
||||
- Hostanme = ipa.linuxtechi.lan
|
||||
- OS: RHEL 8 or Rocky Linux 8 or AlmaLinux 8
|
||||
|
||||
Without further ado, let’s deep dive into FreeIPA installation steps,
|
||||
|
||||
### 1) Set Hostname and Install Updates
|
||||
|
||||
Open the terminal of your server and set the hostname using hostnamectlcommand,
|
||||
|
||||
```
|
||||
$ sudo hostnamectl set-hostname "ipa.linuxtechi.lan"
|
||||
$ exec bash
|
||||
```
|
||||
|
||||
Install updates using yum/dnf command and then reboot it
|
||||
|
||||
```
|
||||
$ sudo dnf update -y
|
||||
$ sudo reboot
|
||||
```
|
||||
|
||||
### 2) Update the hosts file & Set SELinux as Permissive
|
||||
|
||||
Run the below tee command to update /etc/hosts file, replace the ip address and hostname as per your setup.
|
||||
|
||||
```
|
||||
$ echo -e "192.168.1.102\tipa.linuxtechi.lan\t ipa" | sudo tee -a /etc/hosts
|
||||
```
|
||||
|
||||
Set the selinux as permissive, run following commands,
|
||||
|
||||
```
|
||||
$ sudo setenforce 0
|
||||
$ sudo sed -i 's/^SELINUX=.*/SELINUX=permissive/g' /etc/selinux/config
|
||||
]$ getenforce
|
||||
Permissive
|
||||
$
|
||||
```
|
||||
|
||||
### 3) Install FreeIPA and its Components
|
||||
|
||||
FreeIPA packages and its dependencies are available in the Appstream package repositories. As we are planning to install integrated DNS of FreeIPA, so we will also install “ipa-server-dns & bind-dyndb-ldap”
|
||||
|
||||
Run the below command to install FreeIPA and its dependencies
|
||||
|
||||
```
|
||||
$ sudo dnf -y install @idm:DL1
|
||||
$ sudo dnf install freeipa-server ipa-server-dns bind-dyndb-ldap -y
|
||||
```
|
||||
|
||||
### 4) Start FreeIPA Installation
|
||||
|
||||
Once FreeIPA package and it’s dependencies are installed successfully then use the below command to start the freeipa installation setup,
|
||||
|
||||
It will prompt couple of things like to configure Integrated DNS, Host name, Domain Name and Realm Name.
|
||||
|
||||
```
|
||||
$ sudo ipa-server-install
|
||||
```
|
||||
|
||||
Output of above command would be something like below
|
||||
|
||||
After pressing yes in above window, it will take some time to configure your FreeIPA server and once it has been setup successfully then we will get output something like below,
|
||||
|
||||
Above output confirms that FreeIPA has been installed successfully.
|
||||
|
||||
### 5) Allow FreeIPA ports in Firewall
|
||||
|
||||
In case OS firewall is running on your server then run beneath firewall-cmd commands to allow FreeIPA ports,
|
||||
|
||||
```
|
||||
$ sudo firewall-cmd --add-service={http,https,dns,ntp,freeipa-ldap,freeipa-ldaps} --permanent
|
||||
$ sudo firewall-cmd --reload
|
||||
```
|
||||
|
||||
### 6) Access FreeIPA admin portal
|
||||
|
||||
Execute the below ipactl command to check whether all services of FreeIPA are running or not
|
||||
|
||||
```
|
||||
[[email protected] ~]$ ipactl status
|
||||
You must be root to run ipactl.
|
||||
[[email protected] ~]$ sudo ipactl status
|
||||
Directory Service: RUNNING
|
||||
krb5kdc Service: RUNNING
|
||||
kadmin Service: RUNNING
|
||||
named Service: RUNNING
|
||||
httpd Service: RUNNING
|
||||
ipa-custodia Service: RUNNING
|
||||
pki-tomcatd Service: RUNNING
|
||||
ipa-otpd Service: RUNNING
|
||||
ipa-dnskeysyncd Service: RUNNING
|
||||
ipa: INFO: The ipactl command was successful
|
||||
[[email protected] ~]$
|
||||
```
|
||||
|
||||
Let’s verify whether admin user will get token via Kerberos using the kinit command, use the same password of admin user that we supplied during FreeIPA installation.
|
||||
|
||||
```
|
||||
$ kinit admin
|
||||
$ klist
|
||||
```
|
||||
|
||||
Output of above commands,
|
||||
|
||||
Perfect, output above confirms that admin gets the token. Now, try to access FreeIPA Web Console, type following url on web browser,
|
||||
|
||||
https://ipa.linuxtechi.lan/ipa/ui
|
||||
|
||||
or
|
||||
|
||||
https://<Server-IPAddress>/ipa/ui
|
||||
|
||||
Use the user name as admin and the password that we specify during the installation.
|
||||
|
||||
For FreeIPA web console, self-signed ssl certificates are used that’s why we got this window, so click on “Accept the Risk and Continue”
|
||||
|
||||
After entering the credentials, click on ‘Log in‘
|
||||
|
||||
This confirms that we have successfully setup FreeIPA on RHEL 8/Rocky Linux 8 / AlmaLinux8.
|
||||
|
||||
That’s all from this, I hope you have found it informative. Kindly do post your queries and feedback in below comments section.

事不宜迟，让我们深入了解 FreeIPA 安装步骤。
|
||||
|
||||
### 1) 设置主机名并安装更新
|
||||
|
||||
打开服务器的终端并使用 hostnamectl 命令设置主机名：
|
||||
|
||||
```
|
||||
$ sudo hostnamectl set-hostname "ipa.linuxtechi.lan"
|
||||
$ exec bash
|
||||
```
|
||||
|
||||
使用 yum/dnf 命令安装更新，然后重新启动它：
|
||||
|
||||
```
|
||||
$ sudo dnf update -y
|
||||
$ sudo reboot
|
||||
```
|
||||
|
||||
### 2) 更新 host 文件并将 SELinux 设置为 Permissive
|
||||
|
||||
运行以下 tee 命令更新 /etc/hosts 文件，根据你的设置替换 IP 地址和主机名。
|
||||
|
||||
```
|
||||
$ echo -e "192.168.1.102\tipa.linuxtechi.lan\t ipa" | sudo tee -a /etc/hosts
|
||||
```
|
||||
|
||||
将 selinux 设置为 permissive，运行以下命令：
|
||||
|
||||
```
|
||||
$ sudo setenforce 0
|
||||
$ sudo sed -i 's/^SELINUX=.*/SELINUX=permissive/g' /etc/selinux/config
|
||||
]$ getenforce
|
||||
Permissive
|
||||
$
|
||||
```
|
||||
|
||||
### 3) 安装 FreeIPA 及其组件
|
||||
|
||||
Appstream 包仓库中提供了 FreeIPA 包及其依赖项。由于我们计划安装集成 DNS 的 FreeIPA，因此我们还将安装 “ipa-server-dns 和 bind-dyndb-ldap”。
|
||||
|
||||
运行以下命令安装 FreeIPA 及其依赖项。
|
||||
|
||||
```
|
||||
$ sudo dnf -y install @idm:DL1
|
||||
$ sudo dnf install freeipa-server ipa-server-dns bind-dyndb-ldap -y
|
||||
```
|
||||
|
||||
### 4）开始安装FreeIPA
|
||||
|
||||
成功安装 FreeIPA 包及其依赖项后，使用以下命令启动 freeipa 安装设置。
|
||||
|
||||
它将提示几件事，例如配置集成 DNS、主机名、域名和 Realm。
|
||||
|
||||
```
|
||||
$ sudo ipa-server-install
|
||||
```
|
||||
|
||||
上述命令的输出如下所示。
|
||||
|
||||
![][2]
|
||||
|
||||
![][3]
|
||||
|
||||
在上面的窗口中按是后，需要一些时间来配置你的 FreeIPA 服务器，设置成功后，我们将得到下面的输出。
|
||||
|
||||
![][4]
|
||||
|
||||
以上输出确认 FreeIPA 已成功安装。
|
||||
|
||||
### 5) 在防火墙中允许 FreeIPA 端口
|
||||
|
||||
如果系统防火墙正在你的服务器上运行，那么在 firewall-cmd 命令下运行命令允许 FreeIPA 端口：
|
||||
|
||||
```
|
||||
$ sudo firewall-cmd --add-service={http,https,dns,ntp,freeipa-ldap,freeipa-ldaps} --permanent
|
||||
$ sudo firewall-cmd --reload
|
||||
```
|
||||
|
||||
### 6) 访问 FreeIPA 管理门户
|
||||
|
||||
执行下面的ipactl命令查看FreeIPA的所有服务是否都在运行：
|
||||
|
||||
```
|
||||
[[email protected] ~]$ ipactl status
|
||||
You must be root to run ipactl.
|
||||
[[email protected] ~]$ sudo ipactl status
|
||||
Directory Service: RUNNING
|
||||
krb5kdc Service: RUNNING
|
||||
kadmin Service: RUNNING
|
||||
named Service: RUNNING
|
||||
httpd Service: RUNNING
|
||||
ipa-custodia Service: RUNNING
|
||||
pki-tomcatd Service: RUNNING
|
||||
ipa-otpd Service: RUNNING
|
||||
ipa-dnskeysyncd Service: RUNNING
|
||||
ipa: INFO: The ipactl command was successful
|
||||
[[email protected] ~]$
|
||||
```
|
||||
|
||||
让我们使用 kinit 命令验证管理员用户是否会通过 Kerberos 获取令牌，使用我们在 FreeIPA 安装期间提供的相同管理员用户密码。
|
||||
|
||||
```
|
||||
$ kinit admin
|
||||
$ klist
|
||||
```
|
||||
|
||||
以上命令的输出。
|
||||
|
||||
![][5]
|
||||
|
||||
完美，上面的输出确认管理员获得了令牌。现在，尝试访问 FreeIPA Web 控制台，在网络浏览器上输入以下 url：
|
||||
|
||||
https://ipa.linuxtechi.lan/ipa/ui
|
||||
|
||||
或者
|
||||
|
||||
https://<Server-IPAddress>/ipa/ui
|
||||
|
||||
使用我们在安装过程中指定的用户名 admin 和密码。
|
||||
|
||||
![][6]
|
||||
|
||||
对于 FreeIPA Web 控制台，使用自签名 ssl 证书，这就是我们看到此窗口的原因，因此单击“接受风险并继续”。
|
||||
|
||||
![][7]
|
||||
|
||||
输入凭据后，单击“登录”
|
||||
|
||||
![][8]
|
||||
|
||||
这证实我们已在 RHEL 8/Rocky Linux 8 / AlmaLinux8 上成功设置 FreeIPA。
|
||||
|
||||
这就是全部，我希望你觉得它提供了很多信息。请在下面的评论部分中发表你的疑问和反馈。
