下载
wget http://home.tiscali.cz/~cz210552/distfiles/webbench-1.5.tar.gz
解压
tar -zxvf ./webbench-1.5.tar.gz
安装编译环境
yum install -y gcc ctags
编译
cd ./webbench-1.5
make &make install
make clean
如果遇到如下问题：
install: cannot create regular file '/usr/local/man/man1': No such file or directory
make: *** [install] Error 1
网上有说
mkdir /usr/local/man
但是我发现man目录是存在的，那问题只可能是权限了,修改好权限，问题解决。
chmod 777 /usr/local/man
使用
webbench [option]... URL
-f|--force Don't wait for reply from server.
-r|--reload Send reload request - Pragma: no-cache.
-t|--time <sec> Run benchmark for <sec> seconds. Default 30.
-p|--proxy <server:port> Use proxy server for request.
-c|--clients <n> Run <n> HTTP clients at once. Default one.
-9|--http09 Use HTTP/0.9 style requests.
-1|--http10 Use HTTP/1.0 protocol.
-2|--http11 Use HTTP/1.1 protocol.
--get Use GET request method.
--head Use HEAD request method.
--options Use OPTIONS request method.
--trace Use TRACE request method.
-?|-h|--help This information.
-V|--version Display program version.
这里time和clients比较重要，
- time是benchmark持续多久
- clients是指time时间内请求多少次。
比如我们测试百度, 启动100个客户端同时请求百度首页，持续60S：
webbench -t 60 -c 100 http://www.baidu.com/
运行结果
Webbench - Simple Web Benchmark 1.5
