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
