Your JMeter installation may be broken.
You can possibly try the following:

您的 JMeter 安装可能已损坏。
您可能可以尝试以下操作：

1. try to use a fresh installation of last available JMeter versioninstead of your current - if using 2.6 is no requirement in your case;
2. check the integrity of downloaded JMeter archive against PGP or MD5 signatures;
3. class org.apache.jmeter.JMetershould be in the file JMETER_HOME/lib/ext/ApacheJMeter_core.jar. Check if this is there or not. Check that jar is not broken;
4. check that $JAVA_HOMEis defined and points to actual JDK.

1. 尝试使用最新安装的最新可用 JMeter 版本而不是当前版本- 如果在您的情况下不需要使用 2.6；
2. 根据PGP 或 MD5 签名检查下载的 JMeter 存档的完整性；
3. 类org.apache.jmeter.JMeter应该在文件中JMETER_HOME/lib/ext/ApacheJMeter_core.jar。检查这是否存在。检查罐子没有破损；
4. 检查$JAVA_HOME已定义并指向实际 JDK。

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 binfolder and click on the ApacheJmeter.Jar. This will launch the Jmeter UI instance. Also make sure you the Java JDK and JRE installed in your system.

基本上没有安装Jmeter，你不执行或安装文件来安装它。当您从 Apache 站点解压缩下载 zip/gzipbin文件时，导航到该文件夹并单击ApacheJmeter.Jar. 这将启动 Jmeter UI 实例。还要确保您的系统中安装了 Java JDK 和 JRE。

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

您能告诉我们您尝试安装的操作系统版本吗？

ClassNotFoundException has 2 possible meanings:

ClassNotFoundException 有两种可能的含义：

1. You don't have a jar with the class defined
2. You have duplicatedefinitions of that class.

1. 你没有定义类的 jar
2. 您对该类有重复的定义。

Maybe you are stuck with some jar in a folder common to all your java programs? e.g your path, or libraries/java/extensions

也许您在所有 Java 程序共有的文件夹中都被某个 jar 卡住了？例如您的路径，或库/java/扩展

Looks like your JMeter installation is not successful.

看起来您的 JMeter 安装不成功。

java.lang.ClassNotFoundException: org.apache.jmeter.JMeter

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

类 org.apache.jmeter.JMeter 应该在 jar 文件中<JMETER_HOME>/lib/ext/ApacheJMeter_core.jar。运行以下 jar 命令以检查该文件是否存在于 jar 中。

jar -tf <JMETER_HOME>/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.

这听起来可能很奇怪，但我已经看到许多 Java 程序在使用 CentOS 默认附带的 openjdk 运行时会引发此类随机错误。在这种情况下，我可以使用 SUN/Oracle JDK 运行相同的程序。

You should try that if everything else fail.

如果其他一切都失败了，您应该尝试一下。

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

您必须适当地设置 JAVA_HOME 和 PATH，其中包含较新的 java。

Check your JDK version. It should always be the latest for jmeter.

检查您的 JDK 版本。它应该始终是 jmeter 的最新版本。

Below are possbile issues

以下是可能的问题

1. Either Java Path not set properly
2. Your installation of JMeter is not proper
3. Trying to run JMeter from a Invalid directory structure where the necessary lib files are not found
4. Finally your Java version compatibility.

1. Java 路径设置不正确
2. 您的 JMeter 安装不正确
3. 尝试从无效的目录结构运行 JMeter，其中找不到必要的 lib 文件
4. 最后是您的 Java 版本兼容性。

Quick fix:

快速解决：

1. Check your Java Installation from cmd promt with java -version which should be 1.7 or greater
2. If above step works download and unzip/untar JMeter into a new directory and try again.

1. 从 cmd promt 使用 java -version 检查您的 Java 安装，该版本应为 1.7 或更高
2. 如果上述步骤有效，请下载 JMeter 并将其解压缩/解压到新目录中，然后重试。
