需求场景

在Windows环境下测试，并发数过大，整个主机直接崩掉

依赖说明

在Linux系统中运行JMeter脚本，需要有两个前提

1、Linux系统中配置好Java环境

2、Linux系统中配置好JMeter环境。（因为JMeter的运行需要Java环境）

环境说明

Java版本

java -version
openjdk version "17.0.3" 2022-04-19
OpenJDK Runtime Environment (build 17.0.3+7-Ubuntu-0ubuntu0.20.04.1)
OpenJDK 64-Bit Server VM (build 17.0.3+7-Ubuntu-0ubuntu0.20.04.1, mixed mode, sharing)

Linux操作系统

Ubuntu 20.04.4 LTS

下载JMeter

JMeter下载地址：http://jmeter.apache.org/download_jmeter.cgi

参数解释

-n：表示non gui mode，就是非图形化模式。
-t：指定JMX脚本路径，即test plan（测试计划）。后面跟需要运行的JMeter 脚本的路径和脚本名称。
-l：指定结果文件路径。后面跟输出结果文件路径和结果文件名称。-e：设置测试完成后生成测试报表。-e：设置测试完成后生成测试报表。-m：设置测试完成后生成测试报表。
- 1）若没有指定指定结果文件路径，则自动创建，可以生成.csv文件或者.jtl文件。
- 2）若只写脚本名称，则默认是在当前目录查找或创建。
-e：设置测试完成后生成测试报表。
-o：指定测试报表生成文件夹。文件夹必须为空或不存在。

开始测试

/root/apache-jmeter-5.4.1/bin/jmeter -n -t /root/33.jmx -l 33-result.jtl

翻阅官方文档 https://jmeter.apache.org/usermanual/get-started.html

启动 JMeter 时使用的 JVM 内存设置。默认值

-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m

通过设置变量 JVM_ARGS 将覆盖默认预定义的设置

JVM_ARGS="-Xms1024m -Xmx1024m" jmeter -t test.jmx [etc.]

重新改写命令，设置内存为4G

JVM_ARGS="-Xms4024m -Xmx4024m" /root/apache-jmeter-5.4.1/bin/jmeter -n -t /root/33.jmx -l 33-result.jtl

再次运行结果（异常问题已解决）

# JVM_ARGS="-Xms4024m -Xmx4024m" /root/apache-jmeter-5.4.1/bin/jmeter -n -t /root/33.jmx -l 33-result.jtl
