linux啓動jmeter，執行./jmeter.sh報錯解決方法
1.l-bash: ./jmeter.sh: Permission denied
解決辦法：jmeter.sh的執行權限改改，是權限不夠
chmod 777 jmeter.sh
2.An error occurred:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
步驟一：linux負載機環境下,切換到root用戶，運行以下命令安裝X11，該linux機器需能訪問外網：
yum -y install xorg-x11-xauth
yum install xorg-x11-server-utils
yum install xorg-x11-server-Xnest
yum install libXtst
安裝完成後再重新登錄，提示/usr/bin/xauth: creating new authority file /home/upload/.Xauthority
步驟二：本地機器安裝Xming-6-9-0-31-setup.exe，安裝成功後並運行。
步驟三：本地機器安裝putty，putty進行如下配置，選擇SSH—>X11,選中Enable X11 forwarding，X display location中填寫：localhost:0。
