FreeRadius is an implementation of RADIUS server. Its support multiple types of authentication. This article will help you to setup freeradius authentication with OpenLDAP.
Step 1: Setup OpenLDAP Server
First its required to setup openldap server to complete below setup. Use below link to install it.
Step 2: Install freeradius Packages
Install all freeradius2 server packages on your system using following command.
I managed to install coova-chilli with freeradius and postgresql via apt-get and chilli's deb package in Ubuntu. And it works. And it works. For a couple of days, I'm struggling to install the same in CentOS 6.2.
Step 3: Download Schema File
Download radius ldap schema file and copy to ldap schema directory using below commands.
3.1 Download File
3.2 Copy file in schema directory
3.3 Include file in ldap configuration file /etc/openldap/slapd.conf
Step 4: Edit Radius LDAP Files
Edit radius ldap file /etc/raddb/modules/ldap and add below ldap server details.
Edit /etc/freeradius/ldap.attrmap add following details.
Step 5: Enable LDAP Authentication
After updating above files, Lets enable LDAP authentication in /etc/raddb/sites-available/inner-tunnel and /etc/raddb/sites-available/default by uncomment below lines.
Step 6: Test Setup
Finally setup your setup by using following command
If you get rad_recv: Access-Accept then authentication is successes.

Introduction
This tutorial will show you how to install Java on CentOS 7 (also 6 and 6.5), modern Fedora releases, and RHEL. Java is a popular software platform that allows you to run Java applications and applets.
The installation of the following versions of Java are covered:
- OpenJDK 8
- OpenJDK 7
- OpenJDK 6
- Oracle Java 9
- Oracle Java 8
Feel free to skip to your desired section using the Contents button on the sidebar!
Prerequisites
Before you begin this guide, you should have a regular, non-root user with
sudo
privileges configured on both of your servers–this is the user that you should log in to your servers as. You can learn how to configure a regular user account by following the steps in our initial server setup guide for Centos 7.Variations of Java
There are three different editions of the Java Platform: Standard Edition (SE), Enterprise Edition (EE), and Micro Edition (ME). This tutorial is focused on Java SE (Java Platform, Standard Edition).
There are two different Java SE packages that can be installed: the Java Runtime Environment (JRE) and the Java Development Kit (JDK). JRE is an implementation of the Java Virtual Machine (JVM), which allows you to run compiled Java applications and applets. JDK includes JRE and other software that is required for writing, developing, and compiling Java applications and applets.
There are also two different implementations of Java: OpenJDK and Oracle Java. Both implementations are based largely on the same code but OpenJDK, the reference implementation of Java, is fully open source while Oracle Java contains some proprietary code. Most Java applications will work fine with either but you should use whichever implementation your software calls for.
You may install various versions and releases of Java on a single system, but most people only need one installation. With that in mind, try to only install the version of Java that you need to run or develop your application(s).

Install Oracle Java 9
This section of the guide will show you how to install Oracle Java 9 JRE and JDK (64-bit), the latest release of these packages at the time of this writing.
Throughout this section we will be using the
wget
command to download the Oracle Java software packages. wget
may not be included by default on your Linux distribution, so in order to follow along you will need to install it by running:Note: You must accept the Oracle Binary Code License Agreement for Java SE, which is one of the included steps, before installing Oracle Java.
Install Oracle Java 9 JRE
Note: In order to install Oracle Java 9 JRE, you wil need to go to the Oracle Java 9 JRE Downloads Page, accept the license agreement, and copy the download link of the appropriate Linux
.rpm
package. Substitute the copied download link in place of the highlighted part of the wget
command.Change to your home directory and download the Oracle Java 9 JRE RPM with these commands:
Then install the RPM with this yum command (if you downloaded a different release, substitute the filename here):
At the confirmation prompt, enter

Set Default Java
If you installed multiple versions of Java, you may want to set one as your default (i.e. the one that will run when a user runs the
java
command). Additionally, some applications require certain environment variables to be set to locate which installation of Java to use. This section will show you how to do this.By the way, to check the version of your default Java, run this command:
Using Alternatives
The
alternatives
command, which manages default commands through symbolic links, can be used to select the default Java command.To print the programs that provide the
java
command that are managed by alternatives
, use this command:Here is an example of the output:
Simply enter the a selection number to choose which
java
executable should be used by default.Using Environment Variables
Many Java applications use the
JAVA_HOME
or JRE_HOME
environment variables to determine which java
executable to use.For example, if you installed Java to
/usr/java/jdk1.8.0_161/jre/bin
(i.e. java
executable is located at /usr/java/jdk1.8.0_161/jre/bin/java
), you could set your JAVA_HOME
environment variable in a bash shell or script like so:If you want
JAVA_HOME
to be set for every user on the system by default, add the previous line to the /etc/environment
file. An easy way to append it to the file is to run this command:Conclusion
Congratulations, you are now set to run and/or develop your Java applications!
