Your JMeter installation may be broken. 
You can possibly try the following:
<ol>
<li>try to use a fresh installation of <a href="http://jmeter.apache.org/download_jmeter.cgi#binaries" rel="nofollow noreferrer">last available JMeter version</a> instead of your current - if using 2.6 is no requirement in your case;</li>

<li>class <code>org.apache.jmeter.JMeter</code> should be in the file <code>JMETER_HOME/lib/ext/ApacheJMeter_core.jar</code>. Check if this is there or not. Check that jar is not broken;</li>
<li>check that <code>$JAVA_HOME</code> is defined and points to <a href="https://jmeter.apache.org/usermanual/get-started.html#java_versions" rel="nofollow noreferrer">actual JDK</a>.</li>

There is basically no installation of the Jmeter, you don't execute or the set up file to install it. When you download the zip/gzip from the Apache site unzip, navigate to the <code>bin</code> folder and click on the <code>ApacheJmeter.Jar</code>. This will launch the Jmeter UI instance. Also make sure you the Java JDK and JRE installed in your system.

Can you please let us know the OS version you are trying to install?

Looks like your JMeter installation is not successful.

<pre><code>java.lang.ClassNotFoundException: org.apache.jmeter.JMeter
</code></pre>

The class org.apache.jmeter.JMeter should be in the jar file <code>&lt;JMETER_HOME&gt;/lib/ext/ApacheJMeter_core.jar</code>. Run the below jar command to check if the file exists in the jar.

<pre><code>jar -tf &lt;JMETER_HOME&gt;/lib/ext/ApacheJMeter_core.jar

This may sound wierd, but I have seen many java program raise such random errors, when run with openjdk which ships by default with CentOS. In such cases, I could run same programs with SUN/Oracle JDK.

You should try that if everything else fail.

You will have to appropriately set JAVA_HOME and PATH, which has newer java in it.

The only thing needed to run Jmeter is JDK and JRE(which JDK/JRE sersion to be installed depends on the Jmeter version you are installing), which should be installed on your system. And the JRE path should be set in Environment variables. This should be enough to run Jmeter.
