This article uses simple and easy to understand examples to introduce you need to install apache ab?, The code is very detailed, interested friends can refer to it, I hope it can help everyone.

ab is Apache's own website stress testing tool, very simple and convenient to use, not only can Apache server for website access stress testing, but also for other types of servers for stress testing, such as nginx,tomcat, IIS, etc., can be installed as needed.

1: Installation

First of all, download and install it.

Here only talk about window under download installation

Official download address: ,(https://www.apachehaus.com/cgi-bin/download.plx)

Unzip after download

I unzipped it directly into apacheab on disk d.

Modify the port configuration of the conf/httpd.conf file under the unzipped root directory. The default is port 80, which should be occupied and cannot be installed. You can modify it yourself. I modified it here to port 8088.

Extract the file to the local folder, if not extract it in drive c, you need to set the parameters:

My decompression to D disk, need to set parameters, conf->httpd.conf open using a text editor,

There are three areas that need to be modified:

start testing

If you need to type ab test under any path on the command line, you can add the bin directory path to the path of the environment variable

I opened the command line in the bin directory

Note that you need to add/path after the domain name

ab -n 100 -c 10 http://www.baidu.com/s

-n is the number of requests, -c is the number of concurrency.

s is path, indicating that the test address is specified. If it is not specified, an "ab: invalid url" error may be reported.

And then there's-t, which is how many concurrent requests are made in s.

The test results are as follows:
