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
- 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
