How to Install and Configure FreeIPA on CentOS 7 Server
FreeIPA is a free and open source identity management tool, it is the upstream project for Red Hat identity manager. Using FreeIPA tool, we can easily manage centralized authentication along with account management, policy (host-based access control) and audit. FreeIPA also provides the services like DNS and PKI.
FreeIPA is based on the following Open Source projects,
- 389 Directory Server(LDAP)
- MIT Kerberos
- Dogtag (Certificate System)
- NTP & DNS
In this article we will demonstrate how to install and configure FreeIPA tool on CentOS 7 Server. Following are the details of my test Lab Server (CentOS7),
- IP Address = 192.168.0.102
- Hostanme = ipa.linuxtechi.lan
- RAM = 2 GB
- CPU =2 vCPU
- Disk = 12 GB free space on /
- Internet Connection
Step:1 Set static Hostname and apply updates
Set the static host name of your server using the hostnamectl command,
[[email protected] ~]# hostnamectl set-hostname "ipa.linuxtechi.lan" [[email protected] ~]# exec bash [[email protected] ~]#
Update the server using yum update command and then reboot it
[[email protected] ~]# yum update -y;reboot
Step:2 Update the hosts file (/etc/hosts)
Run the below echo command to update /etc/hosts file, replace the ip address and hostname as per your setup.
[[email protected] ~]# echo -e "192.168.0.102\tipa.linuxtechi.lan\t ip" >> /etc/hosts [[email protected] ~]#
Step:3 Install FreeIPA packages using yum command
FreeIPA packages and its dependencies are available in the default package repositories. As we are planning to install integrated DNS of FreeIPA, so we will also install “ipa-server-dns”
Run the below command to install FreeIPA and its dependencies
[[email protected] ~]# yum install ipa-server ipa-server-dns -y
Step:4 Start the FreeIPA Installation setup using “ipa-server-install”
Once the packages 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
[[email protected] ~]# 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 it has been installed successfully.
Run the below command to allow User’s home directory creation automatically after authentication (or login)
[[email protected] ~]# authconfig --enablemkhomedir --update [[email protected] ~]#
Note: In case you get the below errors while installing FreeIPA on CentOS 7 server,
............. [error] CalledProcessError: Command '/bin/systemctl start certmonger.service' returned non-zero exit status 1 ipa.ipapython.install.cli.install_tool(CompatServerMasterInstall): ERROR Command '/bin/systemctl start certmonger.service' returned non-zero exit status 1 ipa.ipapython.install.cli.install_tool(CompatServerMasterInstall): ERROR The ipa-server-install command failed. See /var/log/ipaserver-install.log for more information .................
This seems to be known issue on CentOS 7, so to resolve this we have restart dbus service (service dbus restart) and uninstall freeipa using the command “ipa-server-install –uninstall” and then again try to install.
Step:5 Allow FreeIPA ports in OS Firewall
In case OS firewall is running on your centos 7 server then run the beneath firewall-cmd commands to allow or open ports for FreeIPA,
[[email protected] ~]# firewall-cmd --add-service=freeipa-ldap success [[email protected] ~]# firewall-cmd --add-service=freeipa-ldap --permanent success [[email protected] ~]# firewall-cmd --reload success [[email protected] ~]#
Step:6 Verification & Access FreeIPA admin portal
Use the below command to check whether all services of FreeIPA are running or not
[[email protected] ~]# 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 [[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.
[[email protected] ~]# kinit admin Password for [email protected]: [[email protected] ~]# klist Ticket cache: KEYRING:persistent:0:0 Default principal: [email protected] Valid starting Expires Service principal 11/26/2018 07:39:00 11/27/2018 07:38:55 krbtgt/[email protected] [[email protected] ~]#
Access the FreeIPA admin portal using the URL:
Use the user name as admin and the password that we specify during the installation.
Click on Login
This confirms that we have successfully setup FreeIPA on CentOS 7 Server. It also conclude the article, please do share your feedback and comments.
