New setup for Wordpress 2023.

Standard Hetzner setup. Enable firewall. Move SSH to port 2222. 

     apt update
     apt upgrade
     apt install apache2 php php-mysql
     apt install mariadb-server mariadb-client

Generate a strong password, e.g. with 

   openssl rand -base64 32

Then disable external access, remove anon users, etc, etc: 

     mysql_secure_installation

Create baseline setup with: 

     mysql -u root -p

And give the SQL commands: 

     CREATE DATABASE wordpress_db;
     CREATE USER 'wp_user'@'localhost' IDENTIFIED BY 'PPPPP';
     GRANT ALL ON wordpress_db.* TO 'wp_user'@'localhost' IDENTIFIED BY 'password';
     FLUSH PRIVILEGES;
     Exit;

Where 'PPPPP' is that password generated above.

Fetch the latest Wordpress and check: 

  cd /tmp && wget https://wordpress.org/latest.tar.gz
  openssl sha256 https://wordpress.org/latest.tar.gz
  1. Check sha256 against the Wordpress website.
  cd /var/www/html
  tar zxf /tmp/latest.tar.gz
  cp -R wordpress /var/www/html
  rm /tmp/latest.tar.gz
  chown -R www-data:www-data /var/www/html/wordpress/
  chmod -R 755 /var/www/html/wordpress/
  mkdir /var/www/html/wordpress/wp-content/uploads
  chown -R www-data:www-data /var/www/html/wordpress/wp-content/uploads/

Updated the docroot to Wordpress: 

  vi sites-enabled/000-default.conf

Add settings to /etc/php/*/php.ini: 

   upload_max_filesize=128M 
   post_max_size=128M 
   memory_limit=256M

And restart apache 

  apachectl restart

Then go to the website; and fill out the above details (e.g. wordpress_db, wp_user and password PPPPP).

Backups

Backups have been set up as a variation on Server backups / Duplicity. The main change is that only wordpress and its database are backed up.

The GPG key was set up with the commands: 

    mkdir /etc/duplicity
    cd /etc/duplicity
    export GNUPGHOME=`pwd`
    gpg --generate-key

The passphrase is shown as ZZZZ in below. An easy way to generate a strong passphrase is with: 

    openssl rand -base64 32

Obtain key ID (YYYY in below): 

    gpg --list-secret-keys

The trustee decruption key was taken from the Server backups / Duplicity process and its key id also obtained (XXXX in below): 

    gpg --import public-key.###
    gpg --list-keys

Then edit the trust in this key to `ultimate' 

    gpg --edit-key XXXXXX
    option 5, yes, save

The standard run.sh script was adapted as per below. Note a different MySQL location (change in ubuntu). 

 #!/bin/sh
 set -e
 umask 077
 
 DIR=/etc/duplicity
 W=incremental
 if [ $# != 0 ]; then
 	W=$1
 	shift
 fi
 T=
 if [ $W = full -o $W = incremental ];then
 	T=/
  	mysqldump --all-databases --single-transaction --quick --lock-tables=false  |\
               gzip -9 > /var/lib/mysql/mysql-dump.gz
 fi
  
  # Verbose level 2 is errors and warnings; this way we skip
  # notices and quell all output if the backup is a success.
  #
  VERBOSE=${VERBOSE:-2}
  
  PASSPHRASE="ZZZZZ" LANG=en_US.UTF8  LC_CTYPE=C HOME=$DIR GNUPGHOME=$DIR  \

 			--sign-key           YYY \
 			--ssh-options="-i $DIR/backup.sftp -oUserKnownHostsFile=$DIR/knownhosts" \
 			--no-print-statistics \
 	\
       --include /var/www \
       --include /etc \
 	--include /var/lib/mysql/mysql-dump.gz \
 	--exclude /etc/duplicity/.cache \
 	--exclude '**' \
 	\
 	$T \
 	sftp://xxxx@xxxx.com/backups 2>&1 |\
               tee /var/log/last-duplcity-backup.new |\
               grep -v DeprecationWarning | grep -v algorithm=hashes.SHA1
 	mv /var/log/last-duplcity-backup.new /var/log/duplicity.log
	mv /var/log/duplicity.log.gz /var/log/duplicity.prevlog.gz || true
 	gzip /var/log/duplicity.log || true
 exit $?

And the crons where installed:
