说明
yum-versionlock is a yum plugin that allows administrators to lock specific packages to their currently installed versions, preventing them from being updated during system upgrades. This is useful for maintaining stability when newer package versions might break compatibility or when specific versions are required for compliance. When a package is locked, yum will skip it during yum update operations, even if newer versions are available in configured repositories. The lock persists across reboots and update sessions until explicitly removed. Locked packages are stored in /etc/yum/pluginconf.d/versionlock.list (or similar path depending on the distribution). Each entry follows the NEVRA format: name-epoch:version-release.arch. The plugin must be installed separately via yum install yum-plugin-versionlock (RHEL/CentOS 7) or dnf install python3-dnf-plugin-versionlock (Fedora/RHEL 8+). On newer systems using DNF, the command syntax is dnf versionlock.
