suj · 06-12-2012, 09:16 AM

Hi,

I'm facing some difficulutlies with yum install. When ever I try to install something with yum install it will start updating the repos and taking much time. How should i turn off this updates. it is very much time consuming and waste..

well those aren't yum updates, but the metadata. Try increasing the metadata_expire value for the repos which is, in seconds, the maximum age of the repo contents.

You could also run yum with the "--cacheonly" ("-C") option to make it try to perform the operation using only the cached data.

I have tried using -C option. but get the following error

yum install mod_security -C

mod_security-2.5.12-4.fc15.i686: Caching enabled but no local cache of /var/cache/yum/i386/16/fedora/packages/mod_security-2.5.12-4.fc15.i686.rpm from fedora

Looks like info for that package is not in your cache, so you can't use the -C option.

Another thought, what about scheduling a daily cron job to run:

Code:

yum makecache

       makecache
              Is used to download and make usable all  the  metadata  for  the
              currently enabled yum repos.

Then set metadata_expire=never in /etc/yum.conf. (In RHEL6 mine is set to 90m as the default.)

Then it should be updated in the background daily without causing any delay for you. Best of both worlds as your cache remains current without delays to you.
