From Ubuntu 20.04 LTS

# Packages
    sudo apt update
    sudo apt upgrade
# Create User
    sudo adduser darknoon

Add user to sudo group

    sudo usermod -aG sudo darknoon
# SSH Config

Warn : Each step need to be tested here as it could break the ssh connectivity


## Configure Default SSH port


    sudo vi /etc/ssh/sshd_config

uncomment Port line and set a new port :

    Port 3421

Before closing the SSH window, try the connection using a new SSH client. If its not working revert PasswordAuthentification to yes and reload the service.

# Firewall Config
## Update OpenSSH Profile in UFW Apps with your custom port


    sudo vi /etc/ufw/applications.d/openssh-server

Change line ports to :


    ports=3421/tcp

Enable Firewall with OpenSSH App


    sudo ufw enable
    sudo ufw allow 'Openssh’
    sudo ufw status

Before closing the SSH window, try the connection using a new SSH client. 
If its not working :


    sudo ufw disable

## Set Web Server Working Folder


    mkdir /srv/www/ogspy.fr

Set Correct rights on that folder


    sudo chown ww-data:www-data  -R .

sudo chmod -R 

## Configure Nginx for HTTP

Edit 
Configure a simple Http Server to get your first certificate (See well-known part)

Edit /etc/nginx/sites.available/default


    # Default server configuration
    #
    server {
            listen 80 default_server;
            listen [::]:80 default_server;
            server_name ogspy.fr www.ogspy.fr pma-darkcity.ogspy.fr;
           
    
            root /srv/www/ogspy.fr; #Your root folder
             #Lets Encrypt
            location ~ /.well-known {
                    allow all;
            }
            location / {
            return 301 https://$host$request_uri; # Redirection HTTPS
            }
    }

Start Server

    sudo service nginx start


## Prerequisites HTTPS

Configure Lets Encrypt Certificate


    sudo apt install certbot


    certbot certonly --webroot -w /srv/www/ogspy.fr -d ogspy.fr

Your certificate is now available in /etc/letsencrypt/live/ogspy.fr

## Configure Diffie Hellman Dhparam

https://wiki.openssl.org/index.php/Diffie_Hellman


    cd /etc/ssl/certs
    sudo openssl dhparam -out dhparam.pem 4096


## Configure SSL in NGINX

Nginx : Add this section to your default configuration (/etc/nginx/sites-available/default


    server {
            # SSL configuration
            #
            listen 443 ssl http2 default_server;
            listen [::]:443 ssl http2 default_server;
            #
            # Note: You should disable gzip for SSL traffic.
            # See: https://bugs.debian.org/773332
            #
            # Read up on ssl_ciphers to ensure a secure configuration.
            # See: https://bugs.debian.org/765782
            #
            # Self signed certs generated by the ssl-cert package
            # Don't use them in a production server!
            #
            include snippets/ssl-ogspy.fr.conf; # Will be created just after
            include snippets/ssl-params.conf; # Will be created just after
    
            root /srv/www/ogspy.fr;
    
            #Configurations        
            client_max_body_size 64M;
    
    
            # Add index.php to the list if you are using PHP
            index index.php index.html index.htm index.nginx-debian.html;
    
            server_name ogspy.fr www.ogspy.fr;
    
            location / {
                    # First attempt to serve request as file, then
                    # as directory, then fall back to displaying a 404.
                    try_files $uri $uri/ =404;
            }
    
            # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
            #
            location ~ \.php$ {
                    include snippets/fastcgi-php.conf;
                    
                    # With php7.4-fpm:
                     fastcgi_pass 127.0.0.1:9001;
    #                fastcgi_pass unix:/run/php/php7.0-fpm.sock; #Socket Option
            }
            # deny access to .htaccess files, if Apache's document root
            # concurs with nginx's one
            #
            location ~ /\.ht {
                    deny all;
            }
            #Lets Encrypt
            location ~ /.well-known {
                    allow all;
            }
            # Block xmlrpc.php access
            location = /xmlrpc.php {
                    deny all;
            }
    }

We will now create mentioned files in the snippets folder :
 
Create the file /etc/nginx/snippets/ssl-ogspy.fr.conf for the link with your certificate


    ssl_certificate /etc/letsencrypt/live/ogspy.fr/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/ogspy.fr/privkey.pem;

Create the file /etc/nginx/snippets/ssl-params.conf for the SSL configuration


    # from https://cipherli.st/
    # and https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html

## PHP-FPM

Configure the default Pool :

Open file /etc/php/7.4


    sudo vi /etc/php/7.4/fpm/pool.d/www.conf

Change socket to port 9001

    ; The address on which to accept FastCGI requests.
    ; Valid syntaxes are:
    ;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
    ;                            a specific port;
    ;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
    ;                            a specific port;
    ;   'port'                 - to listen on a TCP socket to all addresses
    ;                            (IPv6 and IPv4-mapped) on a specific port;
    ;   '/path/to/unix/socket' - to listen on a unix socket.
    ; Note: This value is mandatory.
    ;listen = /run/php/php7.4-fpm.sock
    listen = 127.0.0.1:9001 # Configure here
    


You can now try to start your Nginx Server 🙂 

    sudo service nginx start


## MariaDB

Configure Root Access
(Root access is accessible by unix socket)


    sudo mysql_secure_installation

Connect to MariaDb console


    mysql -u root -p

Create User 

    CREATE USER 'darknoon'@localhost IDENTIFIED BY 'password';
    GRANT ALL PRIVILEGES ON *.* TO 'darknoon'@localhost IDENTIFIED BY 'password';
    FLUSH PRIVILEGES;
    SHOW GRANTS FOR 'darknoon'@localhost;

You should now be able to connect to the SQL Server using HeidiSQL for example. Connection using SSH.


## Backup

Create a backup user to allow access from outside.


    sudo adduser userbackup

Add user to sudo group

    sudo usermod -aG backup userbackup

Create for a SSH Keys that you will define in its home folder :  .ssh/authorized_keys (Public key)

Here is the backup script, we can set it anywhere in the filesystem. I use to put it in the root folder but its your choice 🙂 


    #!/bin/bash
    ####################################
    #
    # Backup Files
    #
    ####################################
    
    # What to backup.
    backup_files="/home /etc /root /srv/www"
    
    # Where to backup to.
    dest="/var/archives"
    
    # Create archive filename.
    day=$(date +%F)
    hostname=$(hostname -s)
    archive_file="$hostname-$day.tgz"
    
    # Print start status message.
    echo "Backing up $backup_files to $dest/$archive_file"
    
    if [ ! -f "$dest/$archive_file" ];
    then
    
            # Backup the files using tar.
            tar czf $dest/$archive_file $backup_files
    else
            echo "Backup already generated today"
    fi
    
    ####################################
    #
    # Backup SQL DB
    #
    ####################################
    
    # Print start status message.
    echo "Backing up SQL DB"
    
    for DB in $(mysql -e 'show databases' -s --skip-column-names); do
            if [ ! -f "$dest/$hostname-$day-sql-$DB.gz" ];
            then
                    mysqldump $DB | gzip > "$dest/$hostname-$day-sql-$DB.gz";
            fi
    done
    
    #######################################
    #
    #       Clean Up
    #
    #######################################
    
    find $dest/. -type f ! -name "$hostname-$day*" -execdir rm -i {} +
    chown userbackup:backup $dest/*
    
    # Print end status message.
    echo
    echo "Backup finished"
    date
    
    # Long listing of files in $dest to check file sizes.
    ls -lh $dest


## Set Backup Execution Time


    sudo crontab -e

Select your favorite Editor and add the line :


    0 02 * * * /root/backup.sh

Will run every Day at 2AM.  (https://www.adminschoice.com/crontab-quick-reference)
