wrk 命令安装：

-bash/zsh: wrk: command not found

#Debian
apt-get install wrk

#Ubuntu
apt-get install wrk

#Alpine
apk add wrk

#OS X
brew install wrk

#Raspbian
apt-get install wrk

#Docker
docker run cmd.cat/wrk wrk

wrk 命令补充说明：

wrk 相对于 ab 命令 来说最大的优点是它支持多线程，可以有更大的并发量。

注意：运行 wrk 的机器必须有足够数量的可用临时端口，并且应该快速回收关闭的套接字。为了处理初始连接突发，服务器的 listen(2) backlog 应该大于正在测试的并发连接数。

wrk 命令语法：

wrk -t12 -c400 -d30s http://127.0.0.1:8080/index.html

wrk 命令选项：

-c, --connections: total number of HTTP connections to keep open with
                   each thread handling N = connections/threads

-d, --duration:    duration of the test, e.g. 2s, 2m, 2h

-t, --threads:     total number of threads to use

-s, --script:      LuaJIT script, see SCRIPTING

-H, --header:      HTTP header to add to request, e.g. "User-Agent: wrk"

    --latency:     print detailed latency statistics

    --timeout:     record a timeout if a response is not received within
                   this amount of time.

wrk 做压力测试：

wrk -c 100 -d 30m -t 1 -s test/wrk/rand.lua --latency http://localhost/ -- /path/to/rand-str.txt

以上 wrk 命令输出结果：

wrk -c 100 -d 30m -t 1 -s ngx_waf/test/wrk/rand.lua --timeout 1m --latency http://localhost/ -- /usr/local/src/ngx_waf/txt.txt
