在Linux系统中运行JMeter时遇到了启动报错，提示不要使用GUI模式进行负载测试。通过设置DISPLAY环境变量为:0.0，安装并使用xhost+，成功解决了启动JMeter图形界面的问题。但启动后出现关于字体创建失败的警告。

做各种不同项目的性能测试，都需要在项目本地压测服务器配置jmeter，需要时还要调出jmeter图形化界面来调试jmeter脚本。

标题中的问题遇过多次，这次做个记录。

1. 启动jmeter报错

　　在配置好jmeter环境变量的linux系统执行jmeter命令，报错如下：

[root@localhost ~]# jmeter
= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =  = =
Don't use GUI mode for load testing !, only for Test creation and Test debugging. 
For load testing, use CLI Mode (was NON GUI):
    jmeter -n -t [jmx file] -l [results file] -e -a [Path to web report falder]
& increase Java Heap to meet your test requirements:
    Modify current env variable HEAP="-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m" in the jmeter batch file 
Check:https://jmeter.apache.org/usermanual/best-practices.html

An error occurred: Can't connect to X11 window server using 'lacalhost:12.0' as the value of the display variable.

2. 解决问题

2.1 设置DISPLAY变量

[root@localhost ~]# export DISPLAY=:0.0

2.2 安装xhost

[root@localhost ~]# yum -y install xhost

　　执行xhost+

[root@localhost ~]# xhost +

3. 启动jmeter

　　至此，问题解决。执行jmeter命令启动图形化界面。

[root@localhost ~]# jmeter

    jmeter -n -t [jmx file] -l [results file] -e -o [Path to web report folder]
