背景

        在linux中执行Jmeter脚本时候，大家是否一直使用【jmeter -n -t [jmx file] -l [results file] -e -o [Path to web report folder]】命令执行，是否想过通过shell命令执行或者python执行，今天简单介绍下shell命令执行,前置条件需要配置Jmeter环境变量，如果没有配置，需要在脚本中修改相应位置。

 

效果

shell脚本

Jmeter环境变量配置参考

vi ~/.bash_profile``#jmeter:路径``JMETER_HOME=/root/tools/apache-jmeter-3.3``PATH=$PATH:$HOME/bin:$JMETER_HOME/bin:``export PATH

```#执行生效：``source ~/.bash_profile`

验证

shell脚本参考代码

#!/bin/bash

```# author:liwen`

```# 7DGroup`

```# 2019/12/08/20/50`

```cmdsh="/home/gaolou/apache-jmeter-3.1/bin/JMeterPluginsCMD.`

sh"``case=$1

```mNum=$`

```mark=$4`

```resultDataFileName="resultData.csv"`

```#hostIps="101.201.210.163"`

```` nowPwd=pwd ``` ``echo -e "\033[32m-压力机开始执行。。请等待-\033[1m"`

```````echo testcaseName:{case}_{mNum}_{durationTime}_{mark}`

```if [ -z ${case} ];then`

解释：

第一步

脚本执行方法：

• 先给予可执行权限：chomd a+x startJmeter.sh
• 执行方法：sh startJmeter.sh 脚本名字 并发数  执行时间  备注

解释：

cmdsh="/home/gaolou/apache-jmeter-3.1/bin/JMeterPluginsCMD.sh"

```case=$1 #脚本名字`

```mNum=$2 #并发数`

```durationTime=$3 #执行时间`

```mark=$4 #备注`

```resultDataFileName="resultData.csv"  #csv命令保存数据`

```#hostIps="101.201.210.163" `

```  #如果是多台机器需要取消该注释，把压力机器全部加上`

关键地方解释：

说明：通过sed -i 替换执行并发数、执行时间等信息

sed -i "s#name="ThreadGroup.num_threads">2<#name="ThreadGroup.num_threads">$((2*mNum))<#g" ${filename}.jmx

```sed -i "s#name="ThreadGroup.num_threads">1<#name="ThreadGroup.num_threads">((1*mNum))<#g" {filename}.jmx`

```sed -i "s#ERRORXML#${nowPwd}/${case}/${filename}/${filename}_ERROR.xml#g" ${filename}.jmx`

```sed -i "s#ThreadGroup.scheduler">.*</#ThreadGroup.scheduler">true</#g" ${filename}.jmx`

```sed -i "s#LoopController.loops">.*</#LoopController.loops">-1</#g" ${filename}.jmx`

```sed -i "s#LoopController.continue_forever">.*</#LoopController.continue_forever">true</#g" ${filename}.jmx`

```sed -i "s#ThreadGroup.duration">.*</#ThreadGroup.duration">{durationTime}</#g" {filename}.jmx`

命令执行解释：

说明：通过封装Jmeter -n -t 。。。等信息去执行脚本，该执行命令可以根据自己需要修改

if [ -z ${hostIps} ];then

```#jmeter -n -t ${filename}.jmx -l${filename}.jtl -j ${filename}.log`

```jmeter -n -t ${filename}.jmx -l${filename}.jtl -j ${filename}.log -e -o${filename}`

```else`

```jmeter -n -t ${filename}.jmx -R${hostIps} -l ${filename}.jtl -j${filename}.log -e -o ${filename}`

```#jmeter -n -t ${filename}.jmx -R${hostIps} -l ${filename}.jtl -j${filename}.log`

```fi`

结果保存解释：

说明：通过插件 JMeterPluginsCMD.sh执行获取csv数据，如果想知道该插件详细信息可以百度查询怎么使用。

${cmdsh} --generate-csv ${filename}.csv --input-jtl ${filename}.jtl --plugin-type AggregateReport

```` local sumThread=grep "<stringProp name="ThreadGroup.num_threads">" ${filename}.jmx |awk -F> '{print $2}'|awk -F< 'BEGIN{sum=0}{sum=sum+$1}END{print sum}' ``

```if [ -z ${hostIps} ];then`

```hostNum=1`

```else`

```` hostNum=echo ${hostIps}|awk -F, '{print NF}' ``

```let sumThread=sumThread*hostNum`

```let mNum=mNum*hostNum`

```fi`

```sed -n '2,$p'${filename}.csv|grep -v TOTAL| awk -F, -v case=${filename} -v tnum=${sumThread} -v duration=${durationTime}`

'{printf("%s,%s,%s,%s,%s,%s,%s,%s,90%time:%s;95%time:%s;99%time:%s\n",case,tnum,duration,

```$1,$2,$11,$10,$3,$5,$6,$7)}' >> sDGroup`

```` local totalGroup=cat sDGroup|wc -l ``

```for((i=1;i<=${totalGroup};i++))`

```do`

```sed -n "${i}p" sDGroup|awk -F, -v tnum=${mNum} '{printf("%s,%s,%s,%s,%s,%s,%s,%s,%s,%s\n",$1,$2,$3,$4,tnum,$5,$6,$7,$8,9)}' >>../{resultDataFileName}`

```done`

第二步

脚本写法需要注意

上面脚本写法需要多多注意，否则在通过脚本执行会达不到自己效果；

脚本替换xml说明

实际上shell脚本是替换【ThreadGroup.num_threads">1】

脚本存放目录

第三步

shell脚本存放位置

第四步

执行结果

1. 表示当前执行的脚本名字
2. 表示原始脚本
3. csc结果保存

执行脚本结果目录说明

说明：

打开脚本

vim日志

通过查看日志可以看出执行全部信息，这样方便脚本调试脚本与错误跟踪

 

下载报告

tar命令

```解包：tar zxvf FileName.tar`

```打包：tar zcvf FileName.tar DirName`

sz filename.tar

 

下载解压后打开

tps

 

总结

     通过shell脚本顺利执行Jmeter脚本，如果是长时间执行可以采用后台执行方法，加上【nohup sh startJm.sh 脚本 并发数据 执行时间 备注 &】这样执行不用担心ssh窗口执行Jmeter失败，通过tail -f nohup.log查看执行日志。
