04. LetsEncrypt
----------------------

## Let's make sure that the Nginx domain conf is avaliable
sudo nano /etc/nginx/sites-available/example.com.conf

# # # # # # # # # # # # # # # # # # # # # #
server {
    ...
    ...
    server_name  example.com www.example.com;
    ...
    ...
}
# # # # # # # # # # # # # # # # # # # # # #

## Let's Install Let’s Encrypt Nginx Client
sudo apt-get install python-certbot-nginx -y

## If python-certbot-nginx isn’t already installed, you may have to add its PPA repository and install the package.
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-nginx -y

## Please repleace the below example.com text with your own domain name.
sudo certbot --nginx --agree-tos --email admin@example.com --redirect --hsts -d example.com -d www.example.com

# # # # # # # # # # # # # # # # # # # # # #
## The commands options above are explained below:
### –nginx: Use the Nginx Let’s Encrypt installer
### –agree-tos: Agree to Let’s Encrypt terms of service
### –redirect: Adds 301 redirect.
### –email: Contact email address.
### –hsts: Adds the Strict-Transport-Security header to every HTTP response.
### – d flag is followed by domains you want to secure.
# # # # # # # # # # # # # # # # # # # # # #

## Now, the SSL client should install the cert and configure your website to redirect all traffic over HTTPS.
## The below highlighted code block should be added to your Nginx site configuration file automatically by Let’s Encrypt certbot.
## Your site is ready to be used over HTTPS.

# # # # # # # # # # # # # # # # # # # # # #
server {
    ...
    ...
    server_name  example.com www.example.com;
    ...
    ...
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

    if ($scheme != "https") {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    # Redirect non-https traffic to https
    # if ($scheme != "https") {
    #     return 301 https://$host$request_uri;
    # } # managed by Certbot
    ...
    ...
}
# # # # # # # # # # # # # # # # # # # # # #

## Let's add Let’s Encrypt certificate auto renewal process using crontab 
sudo crontab -e

## Add the line below and save
# # # # # # # # # # # # # # # # # # # # # #
0 1 * * * /usr/bin/certbot renew & > /dev/null
# # # # # # # # # # # # # # # # # # # # # #

## Manual Let's Encrypt Renewal command is below
sudo certbot renew --dry-run


05. HTTP/2
----------------------

## Requirements
### Nginx version 1.9.5 or greater. You can check your Nginx version by running (nginx -v) command.
### OpenSSL version 1.0.2 or greater. You can check your OpenSSL version by running (OpenSSL version) command.
### SSL/TLS certificate from Let's Encrypt or a self-signed certificate.
### TLS 1.2 or higher protocol enabled. Otherwise, you will not be able to use HTTP/2. Implementations of HTTP/2 must use TLS version 1.2 or higher for HTTP/2 over TLS.

## Open the nginx domain conf file
sudo nano /etc/nginx/sites-available/example.com.conf

## Enable the HTTP/2 protocol by adding the http2 parameter to the listen directive in our virtual host:
listen 443 ssl http2;

## Lets reload nginx service
sudo systemctl reload nginx.service

## Examples of nginx virtual server configuration
# # # # # # # # # # # # # # # # # # # # # #
server {
  listen 443 ssl http2;
  listen [::]:443 ssl http2;
  ...
  ...
  ...
  ssl_protocols TLSv1.2;
}
# # # # # # # # # # # # # # # # # # # # # #

## Verify that HTTP/2 is Working from here: https://tools.keycdn.com/http2-test


06. phpMyAdmin
-------------------

## Lets Install phpMyAdmin
sudo apt install phpmyadmin -y

# # # # # # # # # # # # # # # # # # # # # #
## When prompted to choose "Configuring phpmyadmin"
Web server to reconfigure automatically: don’t select anything… just skip and continue. 
Configure database for phpmyadmin with dbconfig-common: Yes
Create a password for phpMyAdmin: Please provide a password for phpmyadmin to register with the database…
# # # # # # # # # # # # # # # # # # # # # #

## Lets create phpMyAdmin code snippets
sudo nano /etc/nginx/snippets/phpmyadmin.conf

## Then copy and paste the code below in the file and save...
# # # # # # # # # # # # # # # # # # # # # #
location /phpmyadmin {
    root /usr/share/;
    index index.php index.html index.htm;
    location ~ ^/phpmyadmin/(.+\.php)$ {
        try_files $uri =404;
        root /usr/share/;
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include /etc/nginx/fastcgi_params;
    }

    location ~* ^/phpmyadmin/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
        root /usr/share/;
    }
}
# # # # # # # # # # # # # # # # # # # # # #

## Lets create your Nginx site configuration file for your domain
sudo nano /etc/nginx/sites-available/example.com.conf

## Then copy and paste the configurations below and save...
# # # # # # # # # # # # # # # # # # # # # #
server {
    listen 80;
    listen [::]:80;
    root /var/www/html/example.com;
    index  index.php index.html index.htm;
    server_name  example.com www.example.com;

     client_max_body_size 100M;

     autoindex off;
  
     location / {
        try_files $uri $uri/ /index.php?$query_string;
      }

    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;
    }

   include snippets/phpmyadmin.conf;
}
# # # # # # # # # # # # # # # # # # # # # #

## Lets enable the site
sudo ln -s /etc/nginx/sites-available/example.com.conf /etc/nginx/sites-enabled/
sudo systemctl restart nginx.service
sudo systemctl restart php7.2-fpm.service

## Now change your domain DNS (A) record and add your server IP as (A) record value.
## Wait few minutes 1-30 minutes (normally but can take up to 72 hours)
## Now browse yourdomain.com/phpmyadmin and try to use (root) user login and password.
## Can't login there? Because, (root) user login is not permitted! Lets fix it below...
sudo mysql -u root
use mysql;
update user set plugin='' where User='root';
flush privileges;
exit
sudo systemctl restart mariadb.service


07. IonCube
----------------------

## Create a php info file in html folder and use your IP to browse it.
## http://your_server_ip/info.php
sudo nano /var/www/html/info.php

## Then paste the below lines from the box without hashes and save and exit.
# # # # # # # # # # # # # # # # # # # # # #
<?php
phpinfo();
# # # # # # # # # # # # # # # # # # # # # #

## Lets Download and unzip IonCube Loader Zip file inside /tmp directory
cd /tmp && wget http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz
tar xfz ioncube_loaders_lin_*.gz

## Then paste the below lines from the box without hashes and save and exit.
# # # # # # # # # # # # # # # # # # # # # #
## Lets find the PHP extensions directory on the system
php -i | grep extension_dir
## example below of the result and remember the directory
extension_dir => /usr/lib/php/20170718 => /usr/lib/php/20170718
# # # # # # # # # # # # # # # # # # # # # #

## Now copy the ioncube loader inside the above extension_dir
sudo cp /tmp/ioncube/ioncube_loader_lin_7.2.so /usr/lib/php/20170718/

## Lets create a file inside /etc/php/7.2/fpm/conf.d/
sudo nano /etc/php/7.2/fpm/conf.d/00-ioncube.ini

## Then paste the below lines from the box without hashes and save and exit.
# # # # # # # # # # # # # # # # # # # # # #
zend_extension = "/usr/lib/php/20170718/ioncube_loader_lin_7.2.so"
# # # # # # # # # # # # # # # # # # # # # #

## Lets restart the web server to take effect.
sudo systemctl restart nginx.service
sudo systemctl restart php7.2-fpm.service

## Lets Verify the ionCube Installation on browser
## Back on the http://your_server_ip/info.php page, refresh the page and search for the "ionCube" keyword.

## Let's create a directory and copy the ioncube file there
sudo mkdir /var/www/ioncube
sudo cp /tmp/ioncube/ioncube_loader_lin_7.2.so /var/www/ioncube/

## Lets install the ioncube inside the server otherwise encryptrd files with ioncube will not work inside server
sudo nano /etc/php/7.2/fpm/php.ini

## Now search for "; End:" to go the bottom of this php.ini.
## Then paste the below lines from the box without hashes and save and exit.
# # # # # # # # # # # # # # # # # # # # # #
zend_extension = /var/www/ioncube/ioncube_loader_lin_7.2.so
# # # # # # # # # # # # # # # # # # # # # #

## Now restart few service to take effect of the php.ini file
sudo systemctl restart nginx.service
