4、Jmeter

官网下载地址：http://jmeter.apache.org/download_jmeter.cgi
wget https://mirrors.tuna.tsinghua.edu.cn/apache//jmeter/binaries/apache-jmeter-3.2.zip

#### windows


#### mac
	配置文件 vim ~/.bash_profile
	添加环境变量配置
		# jmeter
		export JMETER=/Users/chengjiade/Downloads/apache-jmeter-5.1.1     ← Jmeter目录路径
		export CLASSPATH=$JMETER/lib/ext/ApacheJMeter_core.jar:$JMETER/lib/jorphan.jar:$JMETER/lib/logkit-2.0.jar:$CLASSPATH
		export PATH=$PATH:$JMETER/bin  
	source ~/.bash_profile    ← 使配置生效
	jmeter -v	← 查看配置配置是否生效

#### linux
	配置文件vi /etc/profile
	添加环境变量:
		# jmeter
		export JMETER=/Users/chengjiade/Downloads/apache-jmeter-5.1.1     ← Jmeter目录路径
		export CLASSPATH=$JMETER/lib/ext/ApacheJMeter_core.jar:$JMETER/lib/jorphan.jar:$JMETER/lib/logkit-2.0.jar:$CLASSPATH
		export PATH=$PATH:$JMETER/bin
	source /etc/profile    ← 使配置生效
	jmeter -v	← 查看配置配置是否生效
	附：失败提示：
		1、-bash: jmeter: command not found
		很可能是环境变量配置有错，查看路径，名称等是否和jmeter安装文件所在目录一致
		2、-bash: /usr/local/jmeter/apache-jmeter-3.2/bin/jmeter: Permission denied
		说明没有对jmeter的操作权限，需要设置，如下
			chmod 777 filename
			eg:chmod 777 /usr/Jmeter/apache-jmeter-3.2/bin/jmeter
