Linux how to install and use http_load for stress testing on the server, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can get something.

Http_load is a performance testing tool based on linux platform. Run in parallel reuse to test the throughput and load of the web server and test the performance of web pages.

1. Download

Official website: http://acme.com/software/http_load/

The code is as follows:

Cd / root

Wget http://acme.com/software/http_load/http_load-12mar2006.tar.gz

Tar xzf http_load-12mar2006.tar.gz

2. Installation

The code is as follows:

Cd http_load-12mar2006

Make

After executing make, a http_ load binary file is generated in the current directory.

3. Usage

The code is as follows:

Root@www:~/http_load-12mar2006#. / http_load--help

Usage:. / http_load [- checksum] [- throttle] [- proxy host:port] [- verbose] [- timeout secs] [- sip sip_file]

-parallel N |-rate N [- jitter]

-fetches N |-seconds N

Url_file

One start specifier, either-parallel or-rate, is required.

One end specifier, either-fetches or-seconds, is required.

Description of main parameters:

-parallel abbreviation-p: means the number of concurrent user processes.

-rate abbreviation-r: means the frequency of visits per second

-fetches abbreviation-f: means the total number of visits

-seconds abbreviation-s: means total visit time

When selecting parameters,-parallel and-rate choose one of them, and-fetches and-seconds choose one of them.

4. Example:

The code is as follows:

Http_load-parallel 50-s 10 urls.txt

This command line uses 50 processes at the same time and randomly accesses the list of URLs in urls.txt for a total of 10 seconds.

The code is as follows:

Http_load-rate 50-f 5000 urls.txt

50 requests per second, for a total of 5000 stops.

Test the average number of visits a site can take per second:

The code is as follows:

Http_load-parallel 5-fetches 1000urls.txt

This command line uses five processes at the same time and randomly accesses the list of URLs in urls.txt for a total of 1000 visits. The result after running:

1000 fetches, 5 max parallel, 6e+06 bytes, in 58.1026 seconds

6000 mean bytes/connection

17.2109 fetches/sec, 103266 bytes/sec

Msecs/connect: 0.403263 mean, 68.603 max, 0.194 min

Msecs/first-response: 284.133 mean, 5410.13 max, 55.735 min

HTTP response codes:

Code 200-1000

Judging from the above running results, the target website can only withstand 17 visits per second, which is not strong enough.
