# pxelinux.cfg directory
(/afs/psi.ch/service/linux/tftpboot/pxelinux.cfg /tftpboot/pxelinux.cfg)
There are several syntax variants, which can be used for specific pxelinux configuration files. It can do hostnames, ip addresses, hexa encoded expressions of either an IP or a subnet, partial or full MACs. etc.. For details see: https://wiki.syslinux.org/wiki/index.php?title=PXELINUX
# grub.cfg files

Beside the default `grub.cfg` there can similar to `pxelinux` a host or network specific `grub` configuration files.
For details see the [Grub Manual](https://www.gnu.org/software/grub/manual/grub/grub.html#Network), but note that the MAC address documentation is wrong: smiliar as for `pxelinux` the MAC address must be prepended with `01-` to denote the network hardware type Ethernet.

# repo00
This machine is a RHEL7 system **not** under Puppet control. This machine has no AFS dependencies.
The basic service provided by this system is: httpd
This machine acts as a mirror for the RHEL7 iso images.
The installer iso images are downloaded from https://id-sat-prd.ethz.ch/pub/isos/ and put into /var/www/html/iso manually
The iso images in `/var/www/html/iso` then (automatically) mounted as loop devices by the `pli-mount-iso-images.service`. This is an enabled service and it runs once on system boot automatically. Otherwise changes are not monitored, if one puts an iso there and wants it mounted, a manual restart of the service is required for anything to happen.

The `pli-repo-mirror.timer` runs a daily sync (at 21:30), which pulls the repos into `/var/www/html/el7/sources` . The name is misleading, these are actually all the latest repos.
From the above, a weekly snapshot (at Sun 23:30) is taken by the `pli-repo-snapshot.timer`.
The `/opt/pli/libexec/pli-repo-zoom.sh` is run via the `pli-repo-zoom.timer` timer, it maintains the zoom repo at /var/www/html/zoom/
The `/opt/pli/libexec/pli-repo-yfs` script is run via the `pli-repo-yfs.timer` timer. It syncs the auristor repo and apparently also create tags.
The scripts and files in /opt/pli (as well as a copy of the systemd files) can be found in this repository:

# Questions / TODO
- I added the /opt/pli directory under git control, the repo is https://git.psi.ch/linux-infra/repo00_pli-scripts. Ideally the pli-* service files in /etc/systemd/system should be replaced with links to the /opt/pli/systemd/pli* files. Could you please do that and test whether things still work.
- SELinux is enforcing, this will not work.
- Can you explain a little bit more the structure of the /var/www/html/ directory (what is where, who is responsible for certain directories, what are they needed for, ...). The content of the web directory:
```

```
* el7 - where the automated mirroring and snapshotting is done
* iso - where the images are placed and mounted
* zoom - zoom repo
The rest were put there by hand. Much of it is probably not needed, but wouldn't know who needed them.
- Is there any additional documentation on how this system was set up? Where can I find this? If not, could you add here some more details which packages and configs are important (beside the /opt/pli scripts/services)
- I know of no further documentation and it was set up by Kai, years ago. It would take quite a bit of trial and error to reproduce.
- Is the mentiond httpd config everything that is needed, who is taking care of this certificate, how is it installed? how is the expiration monitored?
- I don't think anything further is needed. The cert is requested from SWITCH and placed here manually. It is not monitored. The owner/admin of this server must take care of this.
- Could you replace the files in /etc/httpd/conf.d/25* with a link to /opt/pli/httpd/25* and see whether things still work (this way also the httpd config would be versioned).
- No, SELinux.
- Who belongs this repo? https://repo00.psi.ch/mt86/ (I guess mt86 is a person short code - unfortunately I cannot find this code in the phonebook)
- It's memory test for x86 systems, not a person at PSI.

# repo01.psi.ch
This machine is a RHEL8 system **not** under Puppet control. This machine has no AFS dependencies.
The basic service provided by this system is: httpd
This machine acts as a mirror for the RHEL8 iso images.
Repo01 is connected to the Satelitte server from ETH Zürich. The Red Hat repositories are synced from there.
The installer iso images are downloaded from https://access.redhat.com/downloads and put into `/var/www/html/iso` manually
The iso images in `/var/www/html/iso` are then (automatically) mounted as loop devices by the pli-mount-iso-images.service under `/etc/systemd/system/`. Otherwise changes are not monitored, if a new iso is put there, a manual restart of the service is required for anything to happen.
```bash
df -kh | grep /var/www
/dev/loop0 11G 11G 0 100% /var/www/html/iso/rhel85 /dev/loop1 6.7G 6.7G 0 100% /var/www/html/iso/rhel80
```
Under `/opt/pli/libexec` exist five shell scripts that run with systemctl timer.
The pli-repo-mirror runs a daily sync (at 21:30) via `/etc/systemd/system/pli-repo-mirror.timer`, which pulls the latest repos into `/var/www/html/el8/sources`.
The `gen-snapshot-page` is the basic script to generate a snapshot.
From the above, a weekly snapshot (at Sun 23:30) is taken by the `pli-repo-snapshot` via the `pli-repo-snapshot.timer`
From there the snapshot_is_prodable checks wheter the new snapshot is ready for a new prod tag.
It will check if the latest yfs kernel module corresponds with the latest rhel8 kernel.
If the kernel and the yfs module version correspond a prod snapshot is made under `/var/www/html/el8/tags`
The `pli-repo-zoom` is run via the `pli-repo-zoom.timer`. It maintains the zoom repo at `/var/www/html/zoom/`
The `pli-repo-yfs` script is run via the `pli-repo-yfs.timer`. It syncs the auristor repo and apparently also create tags.
In case of emergency, you can run a snapshot by force. Then you have to add the version before you can run the script
```bash
$./pli-repo-snapshot el8
```
Under `/etc/systemd/system/` we have all the `pli-repo*` timer and service configurations.
In order to start a new timer/service, the service and timer have to be a enabled.
Under `/opt/pli/etc/mirror/` you find the repolist, cuda and yum.conf
Under `/etc/yum.repos.d/` you find the redhat.repo. This are the Red Hat repositories that are synced from ETH.
Under `/var/www/html/el8/keys/` you find the rpm-gpg-keys
Under `/var/www/html/el8/manual/` you find the repos for nxserver. There is no automatic synchronisation for the rpms, they will be downloaded manually from the responsible person.
Under `/var/www/html/el8/snapshots/` you will find all the preprod snapshots
Under `/var/www/html/el8/sources` you will find the packages and repodata from synced rpms.
Under `/var/www/html/el8/tags/` you will find all prod tags
Under `/var/www/html/ipxe` is for testing purposes
Under `/var/www/html/iso` you find the rhel-8.0 and the rhel-8.5 iso image.
Under `/var/www/html/ks-test` you find the new kickstart directory, for testing. If all works this can be deleted.
The URI is https://repo01.psi.ch/el8/sources/
