< p > This runs two (2) instances. Apache/httpd is configured to send < code > /mirrorlist< / code >
to one and < code > /debuglist< / code > to the other.< / p >
< ul >
< li >
< p > Every fifteen (15) minutes: Mirrorlist cache is regenerated< / p >
< ul >
< li > This queries the database for active mirrors and other information and writes a protobuf. The mirrorlist-server reads the protobuf and responds accordingly.< / li >
< / ul >
< / li >
< li >
< p > Every twenty (20) minutes: Service hosting < code > /mirrorlist< / code > is restarted< / p >
< / li >
< li > Every twenty-one (21) minutes: Service hosting < code > /debuglist< / code > is restarted< / li >
< / ul >
< p > Note that the timing for the restart of the mirror list instances are arbitrary.< / p >
< h3 id = "mirror-manager-2" > Mirror Manager 2< a class = "headerlink" href = "#mirror-manager-2" title = "Permanent link" > ¶ < / a > < / h3 >
< p > This is a uwsgi service fronted by an apache/httpd instance. This is responsible
for everything else that is not < code > /mirrorlist< / code > or < code > /debuglist< / code > . This allows the
mirror managers to, well, manage their mirrors.< / p >
< h3 id = "cdn" > CDN< a class = "headerlink" href = "#cdn" title = "Permanent link" > ¶ < / a > < / h3 >
< p > Fastly sits in front of mirror manager. VPN is required to access the < code > /admin< / code > endpoints.< / p >
< p > 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 < code > AppStream/x86_64/os< / code > directory on dl.rockylinux.org. Note that this isn't perfect, but it helps in potential down time or patching.< / p >

< h3 id = "new-release" > New Release< a class = "headerlink" href = "#new-release" title = "Permanent link" > ¶ < / a > < / h3 >
< p > For the following steps, the following must be completed:< / p >
< ul >
< li > Production rsync endpoints should have all brand new content< / li >
< li > New content root should be locked down to 750 (without this, mirror manager cannot view it)< / li >
< li >
< p > Disable mirrormanager user cronjobs< / p >
< / li >
< li >
< p > Update the database with the new content. This is run on a schedule normally (see previous section) but can be done manually.< / p >
< p > a. As the mirror manager user, run the following:< / p >
< / li >
< / ul >
< div class = "highlight" > < pre > < span > < / span > < code > /opt/mirrormanager/scan-primary-mirror-0.4.2/target/debug/scan-primary-mirror --debug --config $HOME/scan-primary-mirror.toml --category ' Rocky Linux'

< / code > < / pre > < / div >
< ol >
< li >
< p > Update the redirects for < code > $reponame-$releasever< / code > < / p >
< p > a. Use psql to mirrormanager server: < code > psql -U mirrormanager -W -h mirrormanager_db_host mirrormanager_db< / code >
b. Confirm that all three columns are filled and that the second and third columns are identical: < code > 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;< / code >
c. Change the < code > majorversion< / code > redirects to point to the new point release, for example: < code > update repository_redirect set to_repo = regexp_replace(to_repo, '9\.0', '9.1') where from_repo ~ '(\w+)-9';< / code > < / p >
< / li >
< li >
< p > Generate the mirrorlist cache and restart the debuglist and verify.< / p >
< / li >
< / ol >
< p > Once the bitflip is initiated, restart mirrorlist and reenable all cronjobs.< / p >

< p > 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'.< / p >
