Using Apache ab to perform http performance testing

Mac comes with Apache environment

Open Terminal and enter sudo apachectl -v (you may need to enter your machine secret). The Apache version is shown below

Then enter sudo apachectl start and Apache will start. Open the Safari browser and enter "http://localhost" in the address bar. You should see a page with the content "It works!". It is located in "/Library/WebServer/Documents/", which is the default root directory of Apache.

Apache's installation directory is: /etc/apache2/, etc is hidden by default. There are three ways to view:

1. Right-click Finder in the dock, select "Go to Folder", and enter "/etc"
2. In finder -> Go -> Go to folder, then enter /etc
3. You can enter "open /etc" in the terminal

Windows can go to http://httpd.apache.org/download.cgi to download, or install from the command line

1. Install Apache

sudo port install apache2

Start Apache: sudo apachectl start

2. brew install pcre

3. wget http://ftp.yz.yamagata-u.ac.jp/pub/network/apache//httpd/httpd-2.4.4.tar.bz2

(1) Decompression
(2) ./configure
(3) make && make install
(4) sudo cp support/ab /usr/sbin

4. ab -n 1000 -c 10 http://localhost:3000/ The last slash is essential

For this ab -n1000 -c10 http://localhost:3000/ command, under the Windows system, you need to first use the cd command to locate the bin folder of your Apache installation directory. . .

-n The number of requests to execute

-c The number of concurrent

-t Maximum time to wait for return

-b TCP send and receive buffer size, unit (byte)
