Using dnf or yum to Upgrade
This section describes how to update or roll back HCE 1.1. The methods for using dnf and yum are the same. In this section, dnf is used as an example.
- HCE 2.0 and later support both yum and dnf.
- HCE 1.1 supports only yum.
Prerequisites
The dnf component has been installed and the dnf commands are available.
[root@localhost bin]# dnf usage: dnf [options] COMMAND List of Main Commands: alias List or create command aliases autoremove remove all unneeded packages that were originally installed as dependencies check check for problems in the packagedb check-update check for available package upgrades clean remove cached data deplist [deprecated, use repoquery --deplist] List package's dependencies and what packages provide them distro-sync synchronize installed packages to the latest available versions downgrade Downgrade a package ......
Context
Yum is a package management utility for Linux distributions, like CentOS. Yum allows for automatic updates and package management on RPM-based distributions. dnf is a rewrite of yum and improves on yum in several ways: improved performance, less memory usage, and better resolution of dependency conflicts. To ensure compatibility, HCE also supports yum commands.
Upgrade Procedure
- Check what RPM package updates are available.
- Run dnf list updates to see the available updates.
