Apache ab压力测试

Windows安装Apache

下载Apache 2.4.39

官网：https://httpd.apache.org

单击Download，打开了下图。

单击a number of third party vendors，得到下图。

选择第一个，打开后，网址为 https://www.apachehaus.com/cgi-bin/download.plx#APACHE24VC14
根据目前系统，选择x64。

下载网址为：https://www.apachehaus.com/downloads/httpd-2.4.39-o102s-x64-vc14.zip

解压

下载后，解压目录为 E:\Program Files\Apache24

配置

修改配置文件 E:\Program Files\Apache24\conf\httpd.conf
a. 38行，注意路径中的空格需要转义。

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#

Define SRVROOT "E:\Program\ Files\Apache24"
ServerRoot "${SRVROOT}"

b. 60行

# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the 
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 8088

c. 225行

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName localhost:8088

添加系统路径
将E:\Program Files\Apache24\bin添加至系统路径。

CentOS 7安装Apache

yum -y install httpd-tools

示例

无参

ab -n 800 -c 800 http://192.168.0.10/
（-n发出800个请求，-c模拟800并发，相当800人同时访问，后面是测试url）

ab -t 60 -c 100 http://192.168.0.10/
在60秒内发请求，一次100个请求。

GET传参

get传参，URL前后必须加双引号，否则 & 符号后面的参数不能被提交。
ab -n 1 -c 1 "http://sy7.net/tests/index.php?name=张三&age=130"

POST参数

ab -n 1 -c 1 -T application/x-www-form-urlencoded -p p.txt http://sy7.net/tests/index.php
p.txt 是和ab.exe在一个目录
p.txt 中可以写参数，如 name=张三&age=120

POST raw

ab -n 1 -c 1 -T application/json -p p.txt http://sy7.net/tests/index.php
ab -n 1 -c 1 -T application/text -p p.txt http://sy7.net/tests/index.php
p.txt内容为：

{
	"name":"张三",
	"age":100
}

携带cookie

-C “Apache=1234; Client=5678”
ab -n 1 -c 1 -C "Apache=1234; Client=5678" http://sy7.net/tests/index.php

命令执行后的输出信息：

ab -n 800 -c 800 http://sy7.net/phpinfo.php
