Build a CentOS7 server for: pxe boot, kickstart, reposync, repotrack, nfs, https (STEP 4)

STEP 4 – CONFIG RepoSync/RepoTrack to support multiple OS Distros, Releases, and Architectures:

As of 2019-03-22, on c7pxe, the c7x64 and c7x32 repos take about this much space…

REPOSYNC OPTIONS (not all of them):

-c CONFIG, –config=CONFIG

Config file to use (defaults to /etc/yum.conf).

CREATE extra YUM config files, one for each {Distro-Release-Arch} being sync’d:
- /etc/yumrsc7x64.conf # configure an exclude= line.
- /etc/yumrsc7x32.conf # configure an exclude= line.
CREATE extra YUM repo directory, one for each {Distro-Release-Arch} being sync’d:
- /etc/yumrsc7x64.repos.d
- /etc/yumrsc7x32.repos.d
CREATE matching repo files under each directory:
- /etc/yumrsc7x64.repos.d/c7x64.repo # {base,extras,updates,epel}
- /etc/yumrsc7x32.repos.d/c7x32.repo # {base,extras,updates}
EDIT each YUM config files to specify where to find it’s “*.repo” files:
- IN “/etc/yumrsc7x64.conf”, add the line “reposdir=/etc/yumrsc7x64.repos.d“
- IN “/etc/yumrsc7x32.conf”, add the line “reposdir=/etc/yumrsc7x32.repos.d“
define reposync CONFIG OPTION for each {Distro-Release-Arch} being sync’d (for the reposync script(s):
- –config=/etc/yumrsc7x64.conf
- –config=/etc/yumrsc7x32.conf

-a ARCH, –arch=ARCH

Act as if running the specified arch (default: current arch,

note: does not override $releasever. x86_64 is a superset for

i*86.).

–arch= # can skip this option/flag for the x64 version, default already works.
–arch= # for the x32… I’m not sure whether it is supposed to be “i386”, “i686”, or something else.
- note: 2019-03-22, seems to working without actually using this flag.

-r REPOID, –repoid=REPOID

Specify repo ids to query, can be specified multiple times

(default is all enabled).

This flag refers to the [repo name] in the configured “*.repo” files.
“REPOID” must match a name in the targeted /etc/yum{$}.repos.d/{$}.repo file(s).
So, if you keep the names simple there, then this flag remains much simpler.
the options used by my repo configs and reposync/repotrack scripts:
- –repoid=base
- –repoid=extras
- –repoid=updates
- –repoid=epel

-d, –delete

Delete local packages no longer present in repository.

-p DESTDIR, –download_path=DESTDIR

Path to download packages to: defaults to current directory.

My local repos are being stored/served in these locations (don’t put this syntax in the script):
- /var/www/html/repos/c7x64/{base,extras,updates,epel}
- /var/www/html/repos/c7x32/{base,extras,updates}
note: the reposync utility will make (or use existing) subfolder(s) matching the repo name, so, my reposync scripts only need:
- –download_path=/var/www/html/repos/c7x64/
- –download_path=/var/www/html/repos/c7x32/

-u, –urls

Just list urls of what would be downloaded, don’t download.

-n, –newest-only

Download only newest packages per-repo.
