Use a specific CentOS mirror
Contents
I want my server to get updates from the CentOS package mirror mirror.nus.edu.sg, here we disable the fastestmirror plugin; e.g.,
$ cat /etc/yum/pluginconf.d/fastestmirror.conf
[main]
enabled=0
verbose=0
socket_timeout=3
hostfilepath=/var/cache/yum/timedhosts.txt
maxhostfileage=10
maxthreads=15
#exclude=.gov, facebook
Now set the mirrorlist, baseurl and failovermethod values for CentOS-Base.repo for the various sections (base, updates, addons, extras, centosplus, contrib). The baseurl value is configured on a per-section basis, so edit carefully.
Here’s mine, reproduced in full:
$ cat /etc/yum.repos.d/CentOS-Base.repo
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
