* restart apache

===SSL===
====Obsolete installation via Backports Packages====
* edit /etc/apt/sources.list and add
 deb http://ftp.debian.org/debian jessie-backports main
* backports are recompiled packages from testing and unstable  in a stable environment so that they will run without new libraries
* update
 apt-get update
* install via Certbot, a script to install and update Let´s Encrypt SSL-certificats
 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

====Upgrade Cerbot from Homepage====
* goto [https://certbot.eff.org/ Certbot Homepage] and select 'Apache' and 'Debian 8 (jessie)' and follow instructions
 sudo apt-get remove certbot
 wget https://dl.eff.org/certbot-auto
 sudo mv certbot-auto /usr/local/bin/certbot-auto
 sudo chown root /usr/local/bin/certbot-auto
 sudo chmod 0755 /usr/local/bin/certbot-auto
* certbot-auto accepts the same flags as certbot
* decommented the backports entry in /etc/apt/sources.list
 sudo apt-get update
* then continue with Certbot configuration
 sudo /usr/local/bin/certbot-auto --apache -d uweheuer.spdns.de
 sudo /usr/local/bin/certbot-auto -d bbx0axbhewglhzf4.myfritz.net
 sudo /usr/local/bin/certbot-auto --apache delete --cert-name uweheuer.goip.de
 // this also edits /etc/apache2/sites-enabled/000-default-le-ssl.conf
* after Fritzbox 7490 to Fritzbox 7590 
 ./certbot-auto -d uweheuer.spdns.de --cert-name 36jjbpz29h1pyywz.myfritz.net
 sudo /usr/local/bin/certbot-auto delete --cert-name bbx0axbhewglhzf4.myfritz.net
 replace in /etc/apache2/sites-enabled/000-default-le-ssl.conf bbx0axbhewglhzf4 with 36jjbpz29h1pyywz
* edit file /etc/cron.d/certbot and decomment old entry from obsolete installation and add
 0 0,12 * * * python -c 'import random; import time; time.sleep(random.random() * 3600)' && /usr/local/bin/certbot-auto renew
=====Manual renew of SSL certificates=====
* login as root@raspberrypi with <STANDARD>:
 cd /usr/local/bin 
 ./certbot-auto renew // this might take very long if an update is needed, obviously requires [[RaspberryPi3B#Operation_3|reboot]] for JBoss to work properly
* easiest is to reboot and than [[RaspberryPi3B#Operation_4|restart Wildfly]] (Wildfly is not startet automatically after reboot)

===TCPDump===
* sudo apt-get install tcpdump

===UweHeuer===
* create database mysql505 with PHPMyAdmin

 ...
* after [[RaspberryPi3B#SSL|SSL]] setup added to [[#Site_Configuration|/etc/apache2/sites-enabled/]]000-default-le-ssl.conf
 ProxyPass /uweheuer ajp://localhost:8009/uweheuer
 ProxyPassReverse /uweheuer http://localhost/uweheuer
 ProxyPass /uweheuer_qa ajp://localhost:8009/uweheuer_qa

 Redirect /uweheuer https://uweheuer.spdns.de/uweheuer
 Redirect /uweheuerqs https://uweheuer.spdns.de/uweheuerqs
 Redirect /owncloud https://uweheuer.spdns.de/owncloud

* create <code>/myprogs</code> and copy DisAndEnableUweHeuer.bat
* Wildfly logger configuratoin according to [[Uweheuer#Server_Logging|here]]
* after deployment uweheuer.war is probably extracted to (vfs stands for virtual file system)
 /home/uwe/raspberry_root/wildfly/wildfly-11.0.0.Final/standalone/tmp/vfs/temp
