Ich parke das mal hier, damit ich das nicht noch mal vergesse. Hat mich eben mal wieder eine Stunde gekostet 😞

Ich wollte meine VMs im Proxmox mit meiner Dockerinstallation auf meinem Haupt-PC überwachen, bis ich feststellte, das diese Dockerinstallation kein IPv6 kann. Mein Netzwerk ist voll IPv6 fähig. Eine kurze Recherche ergab, das das bei Docker gar nicht soo einfach ist. Also wurde der Plan fallen gelassen.
Nun musste was auf dem Proxmox ran. Da ich die Container auch mal wieder ausprobieren wollte, habe ich mir gedacht, gut machen wir so Kurze Anmerkung, es ist im Normalfall nicht sinnvoll, das so zu machen, da man die Server von extern überwachen soll / muss! Für mich ist das aber nicht so wichtig. Was mir wichtiger ist, das ich ab und zu mal schauen kann, wie so der Status der Raids ist, wie voll sind die Platten und son Zeug.....
Die Installation von checkmk nach Dokumentation vorgenommen.
Ich stelle hier direkt fest, das ich mit dem Apachen auf Kriegsfuß stehe. Ich mag das Konzept einfach nicht. Ich hatte mich also nun mal wieder an dieser Konfiguration herangetraut und es nach einiger Zeit auch geschafft. Die Installation war ein Debian Minimal Container.

# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.

# SSL Protocol Adjustments:
# The safe and default but still SSL/TLS standard compliant shutdown
# approach is that mod_ssl sends the close notify alert but doesn't wait for
# the close notify alert from client. When you need a different shutdown
# approach you can use one of the following variables:
# o ssl-unclean-shutdown:
# This forces an unclean shutdown when the connection is closed, i.e. no
# SSL close notify alert is send or allowed to received. This violates
# the SSL/TLS standard but is needed for some brain-dead browsers. Use
# this when you receive I/O errors because of the standard approach where
# mod_ssl sends the close notify alert.
# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection is closed, i.e. a
# SSL close notify alert is send and mod_ssl waits for the close notify
# alert of the client. This is 100% SSL/TLS standard compliant, but in
# practice often causes hanging connections with brain-dead browsers. Use
# this only for browsers where you know that their SSL implementation
# works correctly.
# Notice: Most problems of broken clients are also related to the HTTP
# keep-alive facility, so you usually additionally want to disable
# keep-alive for those clients, too. Use variable "nokeepalive" for this.
# Similarly, one has to force some clients to use HTTP/1.0 to workaround
# their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
# "force-response-1.0" for this.
# BrowserMatch "MSIE [2-6]" \

Was stört mich am Apachen? Ich musste mal wieder irgendwelche Module hinterher installieren, so was wie ssl z.B. Leibe Macher, welche Seite lasst ihr ohne SSL laufen? Ok, vielleicht nur Kleinigkeiten. Weiter gehts mit irgendwelchen Configs, die man aktivieren muss. a2enconf usw. Ja, es mag sein, das ich das Konzept vom Apachen nicht verstehe, ich finde es einfach nur unkomfortabel.
NGINX installieren, Konfigurationsdateien erstellen, einmal neustarten und fertig
Ich habe oben beides angegeben, ihr könnt Euch dann das aussuchen was Euch liegt.
Der Ordnung halber, das Paket
dpkg -i /root/check-mk-free-2.0.0p11_0.buster_amd64.deb
hat eine Abhängikeit Apache2 Der installiert das also mit.
Ich musste am Ende wieder den Apachen installieren, da checkmk zu viele Abhängigkeiten hat. So was wie omd-apache2(?), wurde mir dann als Fehler angezeigt. Die Server waren auf einmal offline usw. Schade, aber letztendlich für den Container auch egal.
Oben im Apachen die SSL Sicherheit erhöht.
