Docker Spielereien

January 7, 2016January 7, 2016 by buyenne

Ein paar Docker Spielereien… auf Ubuntu 14.04 LTS

Alternativ bietet sich seitens Canonical noch LXD an. Kenne mich damit jedoch noch zuwenig aus.

Die passende Cheat Sheet

Install Docker

echo deb http://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list
apt-key adv --keyserver pgp.mit.edu --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
apt-get update
apt-get upgrade
apt-get install -y lxc-docker-1.7.1
ln -sf /usr/bin/docker /usr/local/bin/docker

echo deb http://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list

apt-key adv --keyserver pgp.mit.edu --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9

apt-get update

apt-get upgrade

apt-get install -y lxc-docker-1.7.1

ln -sf /usr/bin/docker /usr/local/bin/docker

Geht inzwischen noch schneller mit

wget -qO- https://get.docker.com/ | sh

1	wget -qO- https://get.docker.com/ \| sh

PHP Memcached unter Plesk / Ubuntu / NGINX aktivieren

October 3, 2015October 3, 2015 by buyenne

Falls memcached noch nicht auf dem System installiert ist:

apt-get install memcached php5-memcached

Bilder Gallerie und ImageMagick unter Plesk 12 / Ubuntu

September 30, 2015 by buyenne

Ich habe ein Album benötigt und habe zuallererst Gallery3 genommen da es schon als Anwendung unter Plesk verfügbar war.

Ich hatte jedoch das Problem, daß es partout nicht das ImageMagick Toolkit nehmen wollte sondern nur GD.

Die fehlende Einstellung fand sich dann bei den PHP Settings unter Plesk.

Plesk Hosting hardening

August 10, 2015 by buyenne

Die aktuelle Basiskonfiguration von Plesk beim Hosting läßt einige Wünsche offen.

Die Bewertung beim Qualys SSL Test war miserabel. Aber es läßt sich relativ einfach beheben.

NGINX dient als Reverse Proxy und das Hosting findet unter Apache statt.

Die ersten Schritte sind hier bestens beschrieben.

Nun werden noch die dhparam angepaßt.

openssl dhparam -out /etc/ssl/dh4096.pem 4096

1	openssl dhparam -out /etc/ssl/dh4096.pem 4096

Weiter geht es mit diesen Änderungen in den folgenden Dateien.

/usr/local/psa/admin/conf/templates/custom/nginxWebmailPartial.php
/usr/local/psa/admin/conf/templates/custom/domain/nginxDomainVirtualHost.php
/usr/local/psa/admin/conf/templates/custom/server/nginxVhosts.php

IPFire – nginx reverse Proxy

August 9, 2015August 9, 2015 by buyenne

Ursprünglich wollte ich Pound als Reverse Proxy nehmen. Jedoch konnte ich keine Weiterleitung auf Ports einrichten. Daher entschied ich mich dann für NGINX,

nginx mit pakfire installieren.

Dann wollen wir den gesamten externen Verkehr auf SSL umstellen. Der Einfachheit halber werden die jeweiligen Server als Virtual Host konfiguriert. Diese kommen in den sites-available Ordner und im sites-enabled per Symlink verknüpft.

cd /etc/nginx/
mkdir sites-available
mkdir sites-enabled

cd /etc/nginx/

mkdir sites-available

mkdir sites-enabled

Anschließend die nginx.conf anpassen.

nano /etc/nginx/nnginx.conf

# Virtual Hosts - am Ende der Datei einfügen

include /etc/nginx/sites-enabled/*;

nano /etc/nginx/nnginx.conf

# Virtual Hosts - am Ende der Datei einfügen

include /etc/nginx/sites-enabled/*;

OpenNebula 4.12 unter Ubuntu 14.10

Diese Lösung schien in manchen Fälle Probleme zu bereiten.

Folgender Weg funktioniert definitiv:

Entsprechenden Agent unter diesem Link herunter laden: http://repo.zabbix.com/zabbix/2.0/debian/pool/main/z/zabbix/

cd ~
mkdir zabbix
cd zabbix
wget http://repo.zabbix.com/zabbix/2.0/debian/pool/main/z/zabbix/zabbix-agent_2.0.6-2+wheezy_amd64.deb
dpkg -i zabbix-agent_2.0.6-2+wheezy_amd64.deb
nano /etc/zabbix/zabbix_agentd.conf

cd ~

mkdir zabbix

cd zabbix

wget http://repo.zabbix.com/zabbix/2.0/debian/pool/main/z/zabbix/zabbix-agent_2.0.6-2+wheezy_amd64.deb

dpkg -i zabbix-agent_2.0.6-2+wheezy_amd64.deb

nano /etc/zabbix/zabbix_agentd.conf

Die üblichen Änderung an der Agent konfiguration kann nun vorgenommen werden (Server IP / Log Verzeichnis / UserParameter usw.)

Der Agent wird mit
[code lang=”bash”]/etc/init.d/zabbix-agent restart[/code]
neu gestartet

Für die UserParameter fehlen noch z.B. die SmartMonTools.

Diese werden mit

apt-get install smartmontools

1	apt-get install smartmontools

nachinstalliert.

UserParameter Einstellungen befinden sich auf der Zabbix Konfigurationsseite.
