How to check Apache ab for benchmarking is installed or not?

[Dipak Bhoi]

Hello Guys,

The Apache ab (apache benchmark) tool typically comes default with RHEL and CentOS systems. It can be used for benchmarking differences in a website (such as before and after optimizing a page) or changing PHP handlers.

You can check if it is install or not by running following command.

#whereis ab

You will get the below output if it is installed on your server.

# whereis ab
ab: /usr/bin/ab /usr/share/man/man1/ab.1.gz

If it is not then you have to remove httpd* from /etc/yum.conf exclude line and run following command to install it.

#yum install httpd-tools

That's all, enjoy !!
