To install Nginx server, run the commands below:
sudo apt update sudo apt install nginx
After installing Nginx, the commands below can be used to stop, start and enable Nginx service to always start up with the server boots,
sudo systemctl stop nginx.service sudo systemctl start nginx.service sudo systemctl enable nginx.service
Now that Nginx is installed. to test whether the web server is working, open your browser and browse to the URL below.
https://localhost
If you see the page above, then Nginx is successfully installed.
WordPress also requires a database server to store its content.If you’re looking for a truly open source database server, then MariaDB is a great place to start. To install MariaDB run the commands below:
sudo apt-get install mariadb-server mariadb-client
After installing MariaDB, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.
Run the following commands
sudo systemctl stop mysql.service sudo systemctl start mysql.service sudo systemctl enable mysql.service
Next, run the commands below to secure the database server with a root password if you were not prompted to do so during the installation.
sudo mysql_secure_installation
When prompted, answer the questions below by following the guide.
Enter current password for root (enter for none): Just press the Enter
Set root password? [Y/n]: Y
New password: Enter password
Re-enter new password: Repeat password
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]: Y
Reload privilege tables now? [Y/n]: Y
Now that MariaDB is installed, to test whether the database server was successfully installed, run the commands below.
sudo mysql -u root -p
type the root password when prompted.
run the commands below to install PHP 7.2-FPM and related modules.
sudo apt install php7.2-fpm php7.2-common php7.2-mysql php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-gd php7.2-xml php7.2-cli php7.2-zip
After installing PHP 7.2, run the commands below to open PHP default configuration file for Nginx…
sudo nano /etc/php/7.2/fpm/php.ini
The lines below is a good settings for most PHP based CMS. Update the configuration file with these and save,
file_uploads = On
allow_url_fopen = On
short_open_tag = On
memory_limit = 256M
cgi.fix_pathinfo = 0
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = America/Chicago
Everytime you make changes to PHP configuration file, you should also restart Nginx web server. To do so, run the commands below:
sudo systemctl restart nginx.service
Now that you’ve installed all the packages that are required for WordPress to function, continue below to start configuring the servers. First run the commands below to create a blank WordPress database.
To logon to MariaDB database server, run the commands below.
sudo mysql -u root -p
Then create a database called wordpress
CREATE DATABASE wordpress;
Create a database user called user with a new password
CREATE USER 'user'@'localhost' IDENTIFIED BY 'new_password_here';
Then grant the user full access to the database.
GRANT ALL ON wordpress.* TO 'user'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;
Finally, save your changes and exit.
FLUSH PRIVILEGES;
EXIT;
To get WordPress latest release you will need to go to its official download page and get it from there… The link below is where to find WordPress latest archive versions…
https://wordpress.org/download/
cd /tmp
wget https://wordpress.org/latest.tar.gz
tar -xvzf latest.tar.gz
sudo mv wordpress /var/www/html/example.com
Then run the commands below to set the correct permissions for WordPress root directory and give Nginx control,
sudo chown -R www-data:www-data /var/www/html/example.com/
sudo chmod -R 755 /var/www/html/example.com/
Run the commands below to create a new configuration file called example.com
sudo nano /etc/nginx/sites-available/example.com
Then copy and paste the content below into the file and save it. Replace the highlighted line with your own domain name and directory root location.
Also make sure to reference the certificate files created above during Cloudflare setup.
server {
listen 80;
listen [::]:80;
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name example.com www.example.com;
root /var/www/html/example.com;
index index.php;
ssl_certificate /etc/ssl/certs/cloudflare_example.com.pem;
ssl_certificate_key /etc/ssl/private/cloudflare_example.com.pem;
ssl_client_certificate /etc/ssl/certs/origin-pull-ca.pem;
ssl_verify_client on;
client_max_body_size 100M;
autoindex off;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
Save the file and exit.
After configuring the VirtualHost above, enable it by running the commands below
sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/
sudo systemctl restart nginx.service
Then open your browser and browse to the server domain name. You should see WordPress setup wizard to complete. Please follow the wizard carefully.
https://example.com/
Then follow the on-screen instructions, Select the installation language then click Continue
You will need to know the following items before proceeding…. Use the database connection info you created above….
Database name
Database username
Database password
Database host
Table prefix (if you want to run more than one WordPress in a single database)
Finish the setup,
and coming to the final part as we have to update ip resolver into cloudflare dns record.
we have to run a script and update your details,
#!/bin/bash
# Cloudflare as Dynamic DNS
# From: https://letswp.io/cloudflare-as-dynamic-dns-raspberry-pi/
# Based on: https://gist.github.com/benkulbertis/fff10759c2391b6618dd/
# Original non-RPi article: https://phillymesh.net/2016/02/23/setting-up-dynamic-dns-for-your-registered-domain-through-cloudflare/
# Update these with real values
auth_email="email@example.com"
auth_key="global_api_key_goes_here"
zone_name="example.com"
record_name="home.example.com"
# Don't touch these
ip=$(curl -s http://ipv4.icanhazip.com)
ip_file="ip.txt"
id_file="cloudflare.ids"
log_file="cloudflare.log"
# Keep files in the same folder when run from cron
current="$(pwd)"
cd "$(dirname "$(readlink -f "$0")")"
log() {
if [ "$1" ]; then
echo -e "[$(date)] - $1" >> $log_file
fi
}
log "Check Initiated"
if [ -f $ip_file ]; then
old_ip=$(cat $ip_file)
if [ $ip == $old_ip ]; then
log "IP has not changed."
exit 0
fi
fi
if [ -f $id_file ] && [ $(wc -l $id_file | cut -d " " -f 1) == 2 ]; then
zone_identifier=$(head -1 $id_file)
record_identifier=$(tail -1 $id_file)
else
zone_identifier=$(curl -s -X GET "https://api.cloudflare.com/client/v4/zones?name=$zone_name" -H "X-Auth-Email: $auth_email" -H "X-Auth-Key: $auth_key" -H "Content-Type: application/json" | grep -Po '(?<="id":")[^"]*' | head -1 )
record_identifier=$(curl -s -X GET "https://api.cloudflare.com/client/v4/zones/$zone_identifier/dns_records?name=$record_name" -H "X-Auth-Email: $auth_email" -H "X-Auth-Key: $auth_key" -H "Content-Type: application/json" | grep -Po '(?<="id":")[^"]*')
echo "$zone_identifier" > $id_file
echo "$record_identifier" >> $id_file
fi
update=$(curl -s -X PUT "https://api.cloudflare.com/client/v4/zones/$zone_identifier/dns_records/$record_identifier" -H "X-Auth-Email: $auth_email" -H "X-Auth-Key: $auth_key" -H "Content-Type: application/json" --data "{\"id\":\"$zone_identifier\",\"type\":\"A\",\"name\":\"$record_name\",\"content\":\"$ip\"}")
if [[ $update == *"\"success\":false"* ]]; then
message="API UPDATE FAILED. DUMPING RESULTS:\n$update"
log "$message"
echo -e "$message"
exit 1
else
message="IP changed to: $ip"
echo "$ip" > $ip_file
log "$message"
echo "$message"
fi
save the file as cloudflare.sh inside pi directory,
run the command,
bash cloudflare.sh
I have done the same as above, https://blog.techiebouncer.com
 using Cloudflare,NGINX - Part 2){kind=link}
