一、环境变量配置：
1. JMETER_HOME ：jmeter安装的路径（浏览目录：定位到jmeter-zip包的解压目录）
2. CLASSPATH： 变量值后新增：
;%JMETER_HOME%\lib\ext\ApacheJMeter_core.jar;%JMETER_HOME%\lib\jorphan.jar;
二、jmeter界面永久设置为中文
找到jmeter下的bin目录，打开jmeter.properties 文件。
language=zh_CN，去掉前面的#，以后打开就是中文界面了。
三、jmeter更改字体大小（来自官网说明）

JMeter with a HiDPI screen on Linux or Windows
22.4 JMeter with a HiDPI screen on Linux or Windows
The HiDPI mode isn't currently support by the Swing API in Java on Linux, MacOS or Windows. Therefore JMeter can be very hard to read with a HiDPI screen (little icons and chars).
You can improve the JMeter's display on HiDPI screen by changing some properties:
jmeter.hidpi.mode
set to true to activate a 'pseudo'-hidpi mode allowing to increase size of some UI elements
jmeter.hidpi.scale.factor
set to 2.0 to scale the size of some UI elements
jmeter.toolbar.icons.size
with these values: 22x22 (default size), 32x32 or 48x48 (Suggested value for HiDPI)
jmeter.tree.icons.size
with these values: 19x19 (default size), 24x24, 32x32 (Suggested value for HiDPI) or 48x48
Additionally you can increase the font size of the text areas in some elements like JSR223 sampler by changing theses properties:
jsyntaxtextarea.font.family
set to Hack to activate and to change the font and their size
jsyntaxtextarea.font.size
set to a greater value, like 28 (Suggested value for HiDPI)
This is not a full HiDPI support and only affects
JMeter tree nodes
Icons in the toolbar
Tables content
Font size into text area
我的设置如下：
jmeter.hidpi.mode = true
jmeter.hidpi.scale.factor= 2.0
jmeter.toolbar.icons.size= 32x32
jmeter.tree.icons.size= 32x32
jsyntaxtextarea.font.family= 微软雅黑
jsyntaxtextarea.font.size= 25
