背景
在 linux 中执行 Jmeter 脚本时候，大家是否始终应用【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，明天简略介绍下 shell 命令执行, 前置条件须要配置 Jmeter 环境变量，如果没有配置，须要在脚本中批改相应地位。
成果
shell 脚本
Jmeter 环境变量配置参考
vi ~/.bash_profile#jmeter: 门路 JMETER_HOME=/root/tools/apache-jmeter-3.3PATH=$PATH:$HOME/bin:$JMETER_HOME/bin:export PATH
执行失效：source ~/.bash_profile
验证
shell 脚本参考代码

解释：
第一步
脚本执行办法：
先给予可执行权限：chomd a+x startJmeter.sh
执行办法：sh startJmeter.sh 脚本名字 并发数 执行工夫 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 #执行工夫
mark=$4 #备注
resultDataFileName=”resultData.csv” #csv 命令保留数据
hostIps=”101.201.210.163″
#如果是多台机器须要勾销该正文，把压力机器全副加上
要害中央解释：
阐明：通过 sed -i 替换执行并发数、执行工夫等信息
sed -i “s#name=\”ThreadGroup.num_threads\”>2<#name=\”ThreadGroup.num_threads\”>$((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：
阐明：通过封装 Jmeter -n -t。。。等信息去执行脚本，该执行命令能够依据本人须要批改
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
后果保留解释：
阐明：通过插件 JMeterPluginsCMD.sh 执行获取 csv 数据，如果想晓得该插件详细信息能够百度查问怎么应用。
${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
脚本写法须要留神
下面脚本写法须要多多留神，否则在通过脚本执行会达不到本人成果；
脚本替换 xml 阐明
实际上 shell 脚本是替换【ThreadGroup.num_threads”>1</stringProp>】
脚本寄存目录
第三步
shell 脚本寄存地位
第四步
执行后果
示意以后执行的脚本名字
示意原始脚本
csc 后果保留
执行脚本后果目录阐明
阐明：
关上脚本
vim 日志
通过查看日志能够看出执行全副信息，这样不便脚本调试脚本与谬误跟踪
下载报告
tar 命令
解包：tar zxvf FileName.tar
打包：tar zcvf FileName.tar DirName
sz filename.tar
下载解压后关上
tps
总结
通过 shell 脚本顺利执行 Jmeter 脚本，如果是长时间执行能够采纳后盾执行办法，加上【nohup sh startJm.sh 脚本 并发数据 执行工夫 备注 &】这样执行不必放心 ssh 窗口执行 Jmeter 失败，通过 tail -f nohup.log 查看执行日志。
