Is it possible to specify a mirror for YUM to target when doing updates? I've noticed on my CentOS 6.2 servers that it takes up to a minute for YUM to respond from a given command. I did some Googling and found that YUM reads from a timedhosts.txt file, so I viewed the contents and it was pretty nasty. There were 49 lines, 32 of which had a value of 99999999999, which I assume to be a timeout.

Do you have the fastest-mirror plugin installed? centos wikiYou could edit the base link, in /etc/yum.repos.d/CentOS-Base.repo, to reflect the repo you would like. I am not sure this is best though.similiar to how this was done with the local repo

CentOS mirror installation media, which currently ships with Foreman, is set to $major/os/$arch. This will not work for CentOS 8 and most likely for next versions as structure of the directories changed due to modularization. Therefore we need to reflect this because the overall goal is that CentOS provisioning should work out of box, even when Katello is not used (which handles this in its own way).

I will then go ahead and rebase my initial PR to a simple installation mirror addition (and rename) since everything else works perfectly. No ther changes in Foreman core are needed and Katello-managed repositories should also work automatically with 8.0 due to the template change (additional_repos) in the 2.1 version.

could you not make this s simple process of just creating two CentOS medias, CentOS current and CentOS Legacy - and as CentOS 7 goes EOL (not doubt around the time of a later Foreman release) just remove CentOS legacy ?

The fastest mirror could vary widely from one geographic location to the next, day to day, hour to hour. It depends on how much traffic your upstream provider has to handle from everywhere, how much their upstream provider has to handle from everywhere, how many other people are hitting the same mirror, how many people are hitting some other service that might live down the same tubes as the mirror, how many things that mirror hosts in addition to Centos, and how many of those things just announced a major release.

In order to help ease the workload for our primary mirror network, the source rpms are not kept in the same tree as the binary packages. If you need the source packages used to build CentOS, you can find them in our vault vault.centos.org.

The VM works on other machines (Windows 7 desktop and an Windows 8.1 laptop), just not the one I need it to work on. I am able to ping the host from the guest and the guest from the host, so there is a connection to the internet.

I think another reason for this error message is if your release is no longer supported. None of the suggestions in this thread worked for me, and my internet connectivity was fine, but then I realized that I'm running Centos 5 (I know, ancient...) which reached its end-of-life on 2017 Mar 31 - right around when the yum repo error started showing up.

This happened to a system I support on a remote network and I determined it was due to the customer's Check Point firewall interfering with normal HTTP traffic. I ran a sudo tcpdump -nn -c 500 -s0 -X port 80 and watched yum get redirected to some kind of portal:

Funny thing is, it was hard to reproduce with curl, which retrieved the mirror list without any problem. I found I had to add the User-agent: urlgrabber/3.1.0 yum/3.2.22 HTTP header that yum uses to trigger Check Point interfering, like this:

Googling for UserCheck/PortalMain shows this is Check Point Firewall. And the IP I obscured there (x.x.x.x) belonged to the customer. This was sufficient proof to tell the customer he needed to make some kind of change to his firewall to allow my system unobstructed internet access (I have no idea what, but I hope he and/or his network team can figure it out).

The answer from @Steve Kehlet above got me on the correct path after finding this Q&A searching for the same symptom. More generally though, the answer turns out to be any sort of filtering web proxy (frequently employed within Corp environments) can cause this when it redirects yum's "http" request. In many of these cases, vendors provide a "web proxy" of some sort (specific to each particular firewall/filtering implementation - ask your sysadmins).

If you see the above error means first you need to check the internet is working or not (ping 8.8.8.8) , if the internet is working means you can debug otherwise check your firewall and get the internet.

The primary vault is going to be regularly overloaded by people trying to get 7.9 items, please use a mirror of the vault like -vault/ or similar.

In order to make this work, you should edit the /etc/CentOS-Base.repo to comment out the

Indeed. What I did was create my own private CentOS 7 repo on a staging server and then created a Cloudflare R2 S3 bucket and uploaded the CentOS 7 repo contents to Cloudflare R2 S3 bucket and enabled subdomain public access and added Cloudflare CDN caching and updated the repo urls to point to my private CentOS 7 repo

I am trying to do a yum update and all of the mirrors fail with a 404. I put the url into my browser and the error is correct, the url does not exist. YUM is looking for a package that does not exist on the mirrors. See below for the error message:

I have a Centos 7 system with an Nvidia Quadro K620 card that has a display port and a DVI output. I have a small display on the DVI output and an Ultra-HD display on the display port through a DP to HDMI adapter.

I went to settings - display settings to configure my monitors and they both show up with the ability to set resolution and rotation but I don't see anything that allows mirroring the monitors. The monitors are spanning each other.

How do I mirror an HDTV Monitor(3480x,1950) from Display Port with a HP monitor (1920x1200) on the DVI port through an Nvidia K620 quadro card using Centos 7 (Without having to drop down to a common lower resolution)?

We are having an issue that seems to have appeared since last week with building OOD on our centos platform and using the rhel-server-rhscl-7-rpms repo. In fact it appears to have emerged just over the past day. Yesterday I could work around it by forcing a specific baseurl for this repo. Today, even the base url I used yesterday is not working.

My Motivation is similar to the last post: I started building my homelab with virtual machines. Most of them are based on a minimal CentOS 7 installation, and as such I have a lot of very similar systems. Yes, I could probably use containers to great effect. But I prefer the separation/isolation that I get from virtual machines on ESXi.

We need a TFTP server and some Syslinux packages. Those two enable booting kernels over the network. The CentOS mirrors provide appropriate images, which we will be using later. Furthermore, a simple HTTP server is required to serve our kickstart configuration and all the packages later.

Point your DHCP clients to this mirror by specifying (at least) [options]( List of DHCP options) 67 and 150. I am using a router flashed with LEDE, so the options can be configured in a single field under Network > DHCP and DNS > TFTP Settings:

Use gpxelinux.0 here to be able to use links to your kernel and initrd in your pxelinux configuration and avoids the need to copy the pxeboot images into the TFTP root seperately. Speaking of configuration ..

Pxelinux expects to find its initial configuration in $tftproot/pxelinux.cfg/default. Thus, create the directory /var/lib/tftpboot/pxelinux.cfg and create a configuration in the file default. A very minimalistic file is sufficient for a single kickstart target:

Adjust kbdmap and the hostname in menu title, kernel, initrd and append lines to fit your network. If you left out the ks=... assignment in the append, you would boot into a minimal CentOS installer by default. To further automate the process we need to create this kickstart configuration next.

I hope this tutorial was somewhat helpful to you. I have created a repository on GitHub to track some of the relevant files and additional post-installation scripts. Take a look and leave a comment if you like!

A CentOS mirror near me has ceph-octopus and ceph-pacific directories. (Stream-8 mirror there has ceph-pacific and ceph-quincy.)

So, there seem to be SIG repos for some recent Ceph versions.

(Nautilus remains that latest for CentOS 7, apparently.)

In this case (my case but I saw also and in other printscreen in this topic, @fasttech, that there are no centos mirrors), I think it was only a matter of yum cache which was solved with the last two commands:

In this case, I tested with just those two commands, and also tried with yum clean all (and done some other tests), and there were still no centos mirrors. But changing the version number (directly in the mirrorlist like @giordy kindly suggested or the distroversion var) succeeded.

If I simply point a server to the Elastic Yum repo at using a copy of the Yum repo config file provided from the elastic web site, it is able to reach out and retrieve the Yum/RPM packages (assuming outbound Internet access is allowed).

But we normally mirror public Yum repos on an internal Pulp server and then point our servers there. Neither the pulp-admin command nor wget can reach out and retrieve the top-level web page at packages/7.x/yum and I get similar issues with various web browsers on my laptop.

It seems like the web server on the elastic side is perhaps looking for specific user-agent strings or something else that distinguishes reposync from a web browser. Usually, Yum repos are viewable via a web browser to the repo URL.
