性能测试工具目前最常见的有以下几种：ab、http_load、webbench、siege。下面讲一下webbench。

webbench最多可以模拟3万个并发连接去测试网站的负载能力，我们可以安装使用。

webbench依赖于ctags，在shell中只需输入ctags即知有没有安装，如果没有要先安装ctags。

ctags安装

安装比较简单：

sudo apt-get install ctags

[root@localhost ~]# yum install ctags
已加载插件：fastestmirror, product-id, search-disabled-repos, subscription-manager

This system is not registered with an entitlement server. You can use subscription-manager to register.

[root@localhost ~]#

webbench安装

进入到用户主目录下：

cd ~

下载压缩包：

wget http://home.tiscali.cz/~cz210552/distfiles/webbench-1.5.tar.gz

解压缩：

tar zxvf webbench-1.5.tar.gz

进入解压缩后的包：

cd webbench-1.5

根据 Makefile文件编译：

sudo make

看一下Makefile文件内容：

CFLAGS?=    -Wall -ggdb -W -O
CC?=        gcc
LIBS?=
LDFLAGS?=
PREFIX?=    /usr/local
VERSION=1.5
TMPDIR=/tmp/webbench-$(VERSION)

all:   webbench tags

tags:  *.c
    -ctags *.c

install: webbench
    install -s webbench $(DESTDIR)$(PREFIX)/bin    
    install -m 644 webbench.1 $(DESTDIR)$(PREFIX)/man/man1    
    install -d $(DESTDIR)$(PREFIX)/share/doc/webbench
    install -m 644 debian/copyright $(DESTDIR)$(PREFIX)/share/doc/webbench
    install -m 644 debian/changelog $(DESTDIR)$(PREFIX)/share/doc/webbench

webbench: webbench.o Makefile
    $(CC) $(CFLAGS) $(LDFLAGS) -o webbench webbench.o $(LIBS) 

clean:
    -rm -f *.o webbench *~ core *.core tags
    
tar:   clean
    -debian/rules clean
    rm -rf $(TMPDIR)
    install -d $(TMPDIR)
    cp -p Makefile webbench.c socket.c webbench.1 $(TMPDIR)
    install -d $(TMPDIR)/debian
    -cp -p debian/* $(TMPDIR)/debian
    ln -sf debian/copyright $(TMPDIR)/COPYRIGHT
    ln -sf debian/changelog $(TMPDIR)/ChangeLog
    -cd $(TMPDIR) && cd .. && tar cozf webbench-$(VERSION).tar.gz webbench-$(VERSION)

webbench.o:    webbench.c socket.c Makefile

.PHONY: clean install all tar

安装：

sudo make install

压测

查看一下帮助：

> webbench -help

输出：

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.

一般常用的是：

> webbench -c 500 -t 30 http://127.0.0.1/test.php

-c 500  并发客户端数
-t 30  时间(秒)

Speed 为每分钟多少个请求，是根据Requests计算出来的

Requests 指定时间内成功多少个请求，失败多少个请求

看一下baidu.com的请求，不过webbench不支持https请求：

ab压测工具使用

ab(Apache Bench)是apache下的一个工具，主要用于做web站点的压力测试。我们下面安装这个工具并压测一下。

安装：

> sudo apt install apache2-utils

压测：

> ab -n 1000 -c 50 http://127.0.0.1/test.php

-n 1000  请求次数
-c 50  并发量 

用https和http访问baidu.com看一下：
