$wgServer = "http://uweheuer.goip.de";

• call http://192.168.178.35/mediawiki/
• to avoid not logged-in users to view or edit anything added the following lines to LocalSettings.php

apachectl -k graceful

• to make owncloud accessible via goip uweheuer domain added to /var/www/html/owncloud/config/config.php in trusted domains

 'trusted_domains' => 
 array (
   0 => '192.168.178.35',
   1 => 'uweheuer.goip.de',
 )

• to make it accessible only via SSL added to /etc/apache2/sites-enabled/000-default.conf

Redirect /owncloud https://uweheuer.goip.de/owncloud

Contacts

• Contacts-App via Market installed
• CardDav URL https://uweheuer.goip.de/owncloud/remote.php/dav/addressbooks/users/uwe.heuer@gmail.com/contacts/ by Contacts -> Settings -> ... -> Link -> Copy URL to Clipboard

• for client configuration see e.g. Samsung Tablet

Upgrade

• user (right top corner) -> settings
• admin area (left area) -> General -> Scroll down to Updater
• install apps again

Backup

Because of rsync errors this approach seems not to work, therefore relying on RaspberryPi3B#Backup

Create DB backup by:

• create /media/ubunturoot permanently
• start Ubuntu HomePC
• login (as root) to Raspberry e.g. by Putty from Windows or Ubuntu
• mount directory for backup by

sudo mount -t cifs -o username=uwe //192.168.178.202/shareroot /media/ubunturoot/
<ROOT_PWD>

• change to Owncloud directory by

cd /var/www/html/owncloud/

• backup DB by

mysqldump --single-transaction -h localhost -u root -p  owncloud > /media/ubunturoot/media/uwe/Data/backup/raspberry/owncloud/DB_<YYYY-MM-DD>.txt

• unmount directory by

umount /media/ubunturoot

PHP

• installed via OwnCloud installation
• increased max file upload size for Wordpress by setting

upload_max_filesize = 4M // before 2M
service apache2 restart

PHPMyAdmin

• installed by

apt-get install phpmyadmin
root root

• add to /etc/apache2/apache2.conf at the end (marked by UH)

Include /etc/phpmyadmin/apache.conf

• changed URL in /etc/phpmyadmin/apache.conf by

Alias /phpxmyadmin /usr/share/phpmyadmin 

• restart apache

SSL

• edit /etc/apt/sources.list and add

deb http://ftp.debian.org/debian jessie-backports main

• update

apt-get update

• install

sudo apt-get install python-certbot-apache
sudo apt-get install certbot -t jessie-backports
sudo certbot --apache
uweheuer.goip.de uwe.heuer@gmail.com

• creates among others /etc/letsencrypt

UweHeuer

• create database mysql505 with PHPMyAdmin
• export and import database
• create /wildfly/wildfly-11.0.0.Final/standalone/data/uweheuer
• copy abc.tmp and /wildfly/wildfly-11.0.0.Final/standalone/data
• download mysql-connector-java-5.1.44-bin.jar from MySQL site
• deploy it via the Wildfly admin console
• create datasources via Web admin console with

MySQLDS
jdbc:mysql://localhost/mysql505?autoReconnect=true
root root
...
UwesWikiDS
...

• after SSL setup added to /etc/apache2/sites-enabled/000-default-le-ssl.conf

ProxyPass /uweheuer ajp://localhost:8009/uweheuer
ProxyPassReverse /uweheuer http://localhost/uweheuer

• /etc/apache2/000-default.conf permanent redirect to SSL

Redirect permanent /uweheuer https://uweheuer.goip.de/uweheuer

• create /myprogs and copy DisAndEnableUweHeuer.bat
• Wildfly logger configuratoin according to here

Wildfly

• create /wildfly directory and chmod 777
• copy wildfly-11.0.0.Final.zip to /wildfly
• unzip
• enable remote access to Wildfly by editing /wildfly/wildfly-11.0.0.Final/standalone/configuration/standalone.xml and replace (save old version to standalone.xml_20171110):

<interface name="management">
  <inet-address value="${jboss.bind.address.management:127.0.0.1}"/>
</interface>
<interface name="public">
  <inet-address value="${jboss.bind.address:0.0.0.0}"/>
</interface>
with
<interface name="management">
  <any-address/>
</interface>
<interface name="public">
  <any-address/>
</interface>

• enable remote CLI access by adding native interface configuration to /wildfly/wildfly-11.0.0.Final/standalone/configuration/standalone.xml (save old version to standalone.xml_20171112)
• set Wildfly as a service by (there is a debian script in the doc directory and a description in the internet, but it didn't work, so used the approach from HomePC New):

create /etc/init.d/uweswildfly
sudo chmod 755 /etc/init.d/uweswildfly
sudo update-rc.d uweswildfly defaults // log goes to /var/log/uwes.log

• enable ajp communication to Apache2 by Web admin -> Configuration -> Subsystems -> Web/HTTP - Untertow -> Http -> View -> default server -> View -> AJP Listeners -> Add 'ajp' 'ajp'

Manual Operation

• cd /wildfly/wildfly-11.0.0.Final/bin
• start server by

./standalone.sh &
disown

• stop server by

./jboss-cli.sh --connect command=:shutdown

• restart server by

./jboss-cli.sh --connect command=:reload

• get server status by

./jboss-cli.sh -c --commands="read-attribute server-state"

Wordpress

Installation

cd /var/wwww/html
wget https://wordpress.org/latest.zip
unzip latest.zip
sudo chown -R www-data:www-data wordpress

• create database wordpress via phpmyadmin
• call https://uweheuer.goip.de/wordpress

user = uwe.heuer@gmail.com
password = Halloo0@1

Increased maximum upload file size by editing PHP.INI.

Plugins

Analyze Network Access

From http://www.lug-erding.de/artikel/nts.html:

telnet <IP|Domain> 80
GET / HTTP/1.1
<ENTER>
Host: <Domain>
<ENTER><ENTER>

If

Trying <IP>

then name resolution works and if

Connected to <IP|Domain>

then TCP is fine and errors are located in higher layers. If

Connection refused

then probably no one listening at port or firewall otherwise see answer.

ping -c <NumberOfPings> -s <Size>

If size is e.g. 4000 pakets have to fragmented which could give hints for the error.

traceroute -n <IP> // Linux
tracert <IP> // Windows

DNS problems could be checked

nslookup <Domain>

Detailled analysis via

tcpdump

Reboot

sudo reboot

Shutdown

sudo shutdown -h 0

Update

sudo apt-get update
