I wanted to self host my WordPress blog and for that I’ve chosen a hosting provider which I no longer recommend..

Because I’m lazy and I don’t know how to configure web servers that well I’ve used XXX’s WordPress one click install, the package installed WordPress and did the following things:

  • Enables the UFW firewall to allow only SSH (port 22, rate limited), HTTP (port 80), and HTTPS (port 443) access.
  • Sets the MySQL root password, runs mysql_secure_installation, and creates a wordpress user with the necessary permissions.
  • Sets up the debian-sys-maint user in MySQL so the system’s init scripts for MySQL will work without requiring the MySQL root user password.
  • Creates the initial WordPress configuration file to set up salt keys and allow the WordPress instance to connect to the database.
  • Disables XML-RPC to help prevent DDoS and other brute force attacks. (Should you require xmlrpc, run “a2disconf block-xmlrpc” from the terminal to disable blocking
  • Modifies some of PHP’s settings to increase the maximum filesize and execution time.
  • Enables the Apache rewrite module so the WordPress permalink feature will work.
  • Configures Apache with UseCanonicalName On to mitigate CVE-2017-8295.

This is pretty convenient as you can setup a fully functional blog in less than 10 minutes, the only thing that is missing is a email configuration.

But, there’s is a problem. Apache2 is old, harder to configure, secure and maintain… I didn’t like it so I wanted to replace it with Nginx.

Initial Preparation

The first step I did was to turn off Apache2 and block the web ports via XXX’s cloud firewall. Blocking the ports is important because I don’t want to serve my initial WordPress configuration file as a txt by accident.

sudo systemctl stop apache2

Next, I’ve installed the necessary dependencies:

sudo apt update
sudo apt install nginx
sudo apt install python-certbot-nginx
sudo apt install php7.2-cli php7.2-fpm php7.2-mysql php7.2-json php7.2-opcache php7.2-mbstring php7.2-xml php7.2-gd php7.2-curl

Configuring Nginx

I’ve deleted the default configuration file from Nginx and created the configuration file for my WordPress blog.

sudo rm /etc/nginx/sites-available/default /etc/nginx/sites-enabled/default
sudo touch /etc/nginx/sites-available/wp-blog
sudo ln -s /etc/nginx/sites-available/wp-blog /etc/nginx/sites-enabled/

Open /etc/nginx/sites-available/wp-blog paste the following things:

# Redirect HTTP -> HTTPS
server {
    listen 80;
    server_name www.domain.tld domain.tld;
    include snippets/letsencrypt.conf;
    return 301 https://domain.tld$request_uri;
# Listen to HTTPS
server {
    listen 443 ssl http2;
    server_name domain.tld;
    root /var/www/html;
    index index.php;
    # SSL parameters
    ssl_certificate /etc/letsencrypt/live/domain.tld/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/domain.tld/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/domain.tld/chain.pem;
    include snippets/ssl.conf;
    include snippets/letsencrypt.conf;
    # log files
    access_log /var/log/nginx/domain.tld.access.log;
    error_log /var/log/nginx/domain.tld.error.log;
    location = /favicon.ico {
        log_not_found off;
        access_log off;
    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    location / {
        try_files $uri $uri/ /index.php?$args;
    location ~ .php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
    location ~* .(js|css|png|jpg|jpeg|gif|ico|svg)$ {
        expires max;
        log_not_found off;

Next, create /etc/nginx/snippets/letsencrypt.conf and paste:

location ^~ /.well-known/acme-challenge/ {
  allow all;
  root /var/lib/letsencrypt/;
  default_type "text/plain";
  try_files $uri =404;

And finally create /etc/nginx/snippets/ssl.conf and paste:

ssl_dhparam /etc/ssl/certs/dhparam.pem;
ssl_session_timeout 1d;
ssl_session_cache shared:SSL:50m;
ssl_session_tickets off;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_stapling on;
ssl_stapling_verify on;
resolver valid=300s;
resolver_timeout 30s;
add_header Strict-Transport-Security "max-age=15768000; includeSubdomains; preload";
add_header X-Frame-Options SAMEORIGIN;
add_header X-Content-Type-Options nosniff;

The last thing we need is to create the dh-param.pem file:

sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

Now, to test that our configuration is valid we run nginx -t. You shouldn’t see any errors.

Note: You should replace the domain.tld with our own domain. I already had the Let’s Encrypt certificate on the machine, if you don’t have one then you should generate one using certbot.

Uninstalling Apache2

You should start the website and check if it’s running correctly, then you may uninstall apache2.

sudo apt-get purge apache2
sudo rm -rf /etc/apache2 


I got rid of Apache2 in less than 20 minutes and the blog is up and running. If you’re going to attempt to do this please make a backup first!
