YUM

OTHER not


How can I mirror the Yum channels?
A:The latest YUM repository files are hosted at https://yum.oracle.com/mirror

To create local mirrors of repositories on yum.oracle.com, follow these directions:
Download the repository files for those repos you want to synchronize to /etc/yum.repos.d directory, using curl or wget
For example:
# wget https://yum.oracle.com/mirror/ol8/x86_64/oracle-linux-ol8-x86_64.repo -O /etc/yum.repos.d/oracle-linux-ol8-x86_64.repo
Or
# curl https://yum.oracle.com/mirror/ol8/x86_64/oracle-linux-ol8-x86_64.repo -o /etc/yum.repos.d/oracle-linux-ol8-x86_64.repo

In each .repo file, change enabled=0 to enabled=1 for the repositories you want to sync

If you plan to sync repositories for multiple architectures, be sure to update repository names to avoid duplicates

Start the download using the reposync command, for example:
Oracle Linux 8:
# dnf reposync --download-path <download path> --download-metadata

Oracle Linux 7:
# reposync --download_path <download path> --download-metadata


proxy not

How do I use Oracle Linux yum server if my system is behind a proxy server?
A: To configure yum to use a proxy for all users on a systen, add your proxy server details to /etc/yum.conf. Note that both a http://or https:// prefix and TCP port are required.

     proxy=http://proxy.mydomain.com:8080
If your proxy server requires authentication, add these settings to /etc/yum.conf:

      proxy_username=<proxy username>
      proxy_password=<proxy password>
To configure a proxy server for a single user or session, set the https_proxy or http_proxy environment variable and optionally add these settings to ~/.bash_profile. Note that a protocol prefix is optional:

      https_proxy=proxy.mydomain.com:8080
      export https_proxy
If you've configured proxy settings for a non-root user or session only, remember that many yum commands require root privileges. So, when using sudo, you must use -E to preserve the existing environment. For example:

      sudo -E yum install <some package>
