Create an rpm package in Centos

There are many friends who talk about RPM compilation and installation. RPM installation is a dumb installation.
In fact, RPM is a very effective centralized deployment solution.
Yum + RPM is a fast and convenient large-scale deployment solution.
The following describes how to create an rpm:
Taking cronolog as an example:
First download the source code package of cronolog.
Undo source package, tar xzvf cronolog-1.6.2.tar.gz
Find cronolog. spec. This file is a configuration file that customizes how to generate an RPM package.

Copy the code and copy the source code package to/usr/src/redhat/SOURCES/
Cronolog-1.6.2.tar.gz/usr/src/redhat/SOURCES/
Run rpmbuild-ba cronolog. spec
In this way, the RPM package is generated, ^ _ ^
