The /etc/yum.conf
file is the primary configuration file for the YUM Package Manager, which is used by RPM-based Linux distributions to manage software packages. This file contains default options like repository sources, network settings, and more that dictate how packages are handled, installed, upgraded, and removed.
Improper configuration of the /etc/yum.conf
file can lead to several issues, such as:
Adjusting cache settings can help manage disk space and improve performance. Set keepcache=0
to clean the cache after an install, or keepcache=1
to retain all files:
keepcache=1
Modify the timeout setting to avoid long delays in case of unreachable repositories. A lower value can reduce wait times:
timeout=10
Limiting bandwidth can be crucial on networks with bandwidth constraints. Use the throttle
option to limit YUM's download rate:
throttle=50k
Enabling the fastest mirror plugin can enhance download speeds by selecting the best mirror based on connection speed:
fastestmirror=True
Setting priorities for repositories, especially for security updates, ensures that essential patches are applied first. Use the priorities
plugin and configure it appropriately:
[main]
enabled=1
gpgcheck=1
