安装WebBench
mkdir /tools
cd /tools
wget http://www.ha97.com/code/webbench-1.5.tar.gz
tar zxvf webbench-1.5.tar.gz
cd webbench-1.5
make && make install
WebBench使用
webbench -c 1000 -t 60 http://192.168.80.157/phpinfo.php
webbench -c 并发数 -t 运行测试时间 URL
make install安装报错
cannot create regular file '/usr/local/man/man1': No such file or directory
解决方案：mkdir /usr/local/man 然后在make install
