To update the software source list using YUM (Yellowdog Updater Modified), you can use the following command:
sudo yum update
This command not only updates the existing packages to their latest versions but also refreshes the metadata of the repositories, ensuring that you have the most recent information about available packages.
If you want to update only the metadata without upgrading any packages, you can use:
sudo yum clean all
sudo yum makecache
The yum clean all command removes any cached data, and yum makecache regenerates the cache, effectively updating the software source list.
For example, if you are managing a server and want to ensure that all software packages are up-to-date and that the repository information is current, running sudo yum update would be the appropriate action.
In the context of cloud computing, if you are using a cloud service provider like Tencent Cloud, you might manage your server instances through their console or APIs. Updating the software source list on these instances would follow the same YUM commands as described above. Additionally, Tencent Cloud offers services like Tencent Cloud Container Registry (TCR) and Tencent Cloud TKE (Tencent Kubernetes Engine), where managing software updates and repository configurations can be automated and integrated into your CI/CD pipelines.
