This runs two (2) instances. Apache/httpd is configured to send `/mirrorlist`
to one and `/debuglist` to the other.
* Every fifteen (15) minutes: Mirrorlist cache is regenerated
* This queries the database for active mirrors and other information and writes a protobuf. The mirrorlist-server reads the protobuf and responds accordingly.
* Every twenty (20) minutes: Service hosting `/mirrorlist` is restarted
* Every twenty-one (21) minutes: Service hosting `/debuglist` is restarted
Note that the timing for the restart of the mirror list instances are arbitrary.
### Mirror Manager 2
This is a uwsgi service fronted by an apache/httpd instance. This is responsible
for everything else that is not `/mirrorlist` or `/debuglist`. This allows the
mirror managers to, well, manage their mirrors.
### CDN
Fastly sits in front of mirror manager. VPN is required to access the `/admin` endpoints.
If the backend of the CDN is down, it will attempt to guess what the user wanted to access and spit out a result on the dl.rockylinux.org website. For example, a request for AppStream-8 and x86_64 will result in a `AppStream/x86_64/os` directory on dl.rockylinux.org. Note that this isn't perfect, but it helps in potential down time or patching.
b. Confirm that all three columns are filled and that the second and third columns are identical:
```
select rr.from_repo AS "From Repo", rr.to_repo AS "To Repo", r.prefix AS "Target Repo" FROM repository_redirect AS rr LEFT JOIN repository AS r ON rr.to_repo = r.prefix GROUP BY r.prefix, rr.to_repo, rr.from_repo ORDER BY r.prefix ASC;`
```
c. Change the `majorversion` redirects to point to the new point release, for example:
insert into repository_redirect (from_repo,to_repo) select REGEXP_REPLACE(rr.from_repo,'9\.2','9.3'),REGEXP_REPLACE(rr.to_repo,'9\.2','9.3')FROM repository_redirect AS rr WHERE from_repo ~ '(\w+)-9.2';
1. Get current shasum of repomd.xml. For example: `shasum=$(curl https://dl.rockylinux.org/pub/rocky/9.3/BaseOS/x86_64/os/repodata/repomd.xml | sha256sum)`
This will generate a table. You can take the IDs in the first column and use the database to disable them by ID (table name: hosts) or go to https://mirrors.rockylinux.org/mirrormanager/host/ID and uncheck 'User active'.
Users can change user active, *but* they cannot change admin active. It is better to flip user active in this case.
Admins can also view https://mirrors.rockylinux.org/mirrormanager/admin/all_sites if necessary.
These mirrors are here soley as an example and not to call anyone out, every mirror shows up on here at one point, for some reason, due to natural variations in how mirrors sync.
