I accidental deleted the configuration file stored in /etc/ directory and the latest backup were made yesterday. How do I resinstall the package using the yum command under RHEL / CentOS Linux server?
You can use the yum command with reinstall option. This will reinstall the identically versioned package as is currently installed. The syntax is as follows:
yum reinstall packageName yum reinstall packageName1 packageName2

Note: This does not work for “installonly” packages such as RHEL kernels packages.Share this tutorial on:
