PHP

PHP5

• installed via OwnCloud installation. Is is not clear which ini-file is used:

./etc/php5/cli/php.ini
./etc/php5/apache2/php.ini // this one is used according phpinfo()

• increased max file upload size for Wordpress by setting

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

PHP7.2

• installation according to here

sudo apt update
sudo apt install php7.2
sudo apt install php7.2 php7.2-cli php7.2-cgi php7.2-common php7.2-curl php7.2-gd php7.2-json php7.2-mbstring php7.2-mysql php7.2-opcache php7.2-readline php7.2-xml libapache2-mod-php7.2

• and in order to make Owncloud work with 7.2

apt-get install php7.2-intl
apt-get install php7.2-zip
service apache2 restart

• and in order to make Msupload extension of Mediawiki to work

apt-get install php7.2-bcmath
service apache2 restart

• ini-files:

./etc/php/7.2/cli/php.ini
./etc/php/7.2/apache2/php.ini // this one is used according phpinfo()

• switch to PHP7.2 (PHP5 remains installed)

a2dismod php5
a2enmod php7.2
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

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 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 reboot for JBoss to work properly

• easiest is to reboot and than restart Wildfly (Wildfly is not startet automatically after reboot)

TCPDump

• sudo apt-get install tcpdump

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

• create datasources via Web admin console with

MySQLDS (see File:RaspberryMySQL505Configuration.pdf)
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
ProxyPass /uweheuer_qa ajp://localhost:8009/uweheuer_qa
ProxyPassReverse /uweheuer_qa http://localhost/uweheuer_qa

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>
