Install Boto3 AWS SDK for Python

Boto3 is the Amazon Web Services (AWS) SDK for Python, which allows Python developers to write software that makes use of Amazon services like S3 and EC2. Boto provides an easy to use, object-oriented API as well as low-level direct service access.

To install on Mac

sudo easy_install pip
sudo pip install —ignore-installed six boto3

sudo easy_install pip sudo pip install —ignore-installed six boto3

You need to set up your credentials and config file to authenticate to AWS first. The files are:

.aws/credentials
.aws/config

After it’s installed and configured, try using Boto3 to fetch your AWS S3 buckets.

import boto3
s3 = boto3.resource('s3')
for bucket in s3.buckets.all():
  print(bucket.name)

import boto3 s3 = boto3.resource('s3') for bucket in s3.buckets.all(): print(bucket.name)

Your S3 buckets will be listed after execution.

Boto3 has access to other AWS resources like EC2, meaning you can start and stop instances via Python and Boto3.

Install AWS CLI on Ubuntu

The advantage of running Amazon Linux on AWS is that you already have the AWS CLI (command line interface) loaded as part of the image. In addition, Amazon Linux has rolling updates. It means you don’t have to perform major upgrades as you go to from one version to another. It’s all part of the process when you perform periodical updates. However, if you’re running Ubuntu, it’s no slouch. It’s a popular distro which many administrators have chosen to use due to its simplicity and robust repository. So, if you’re running Ubuntu, you might want to install the AWS CLI to give you the tools you need similar to what Amazon Linux has. Here’s how to install AWS CLI on Ubuntu.

$ sudo apt install awscli

$ sudo apt install awscli

You will need to run the configuration before you can start using AWS CLI. See example below.

$ sudo aws configure
AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default region name [None]: us-west-2
Default output format [None]: json

$ sudo aws configure AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY Default region name [None]: us-west-2 Default output format [None]: json

Obviously, you will need your own Access Key and Secret Key that you’ll need to generate from your AWS Console under IAM.

NextCloud Install

NextCloud is an open-source next-generation file sharing and file synching web-application that you can run and install on your own Linux server. It’s similar to Dropbox, the file-sharing cloud application. The big difference between Dropbox and NextCloud is that you get to run your own cloud storage on your own server. The following are instructions on how to install NextCloud on an Ubuntu Server 16.04 LTS server.

Run Updates First

$ sudo apt-get update
$ sudo apt-get upgrade -y
$ sudo apt-get dist-upgrade -y

$ sudo apt-get update $ sudo apt-get upgrade -y $ sudo apt-get dist-upgrade -y

Install Apache

$ sudo apt-get install apache2

$ sudo apt-get install apache2

Install MySQL Server

$ sudo apt-get install mysql-server mysql-client
$ sudo mysql_secure_installation

$ sudo apt-get install mysql-server mysql-client $ sudo mysql_secure_installation

Install PHP

$ sudo apt-get install php libapache2-mod-php php-mbstring php-zip php-xml php-mysql php-gd
$ sudo apt-get install php-json php-curl php-intl php-mcrypt php-imagick php-dom unzip

$ sudo apt-get install php libapache2-mod-php php-mbstring php-zip php-xml php-mysql php-gd $ sudo apt-get install php-json php-curl php-intl php-mcrypt php-imagick php-dom unzip

Edit php.ini change the memory limit and upload and post file sizes to something bigger. Restart Apache.

$ sudo nano /etc/php/7.0/apache2/php.ini
memory_limit = 512M
upload_max_filesize = 500M
post_max_size = 500M
$ sudo service apache2 restart

$ sudo nano /etc/php/7.0/apache2/php.ini memory_limit = 512M upload_max_filesize = 500M post_max_size = 500M $ sudo service apache2 restart

Create Database and User. Flush privileges.

$ mysql -u root -p
mysql> create database nextcloud;
mysql> grant all privileges on nextcloud.* to 'ncuser'@'localhost' identified by 'password';
mysql> flush privileges;
mysql> exit;

$ mysql -u root -p mysql> create database nextcloud; mysql> grant all privileges on nextcloud.* to 'ncuser'@'localhost' identified by 'password'; mysql> flush privileges; mysql> exit;

Download and Install the latest Nextcloud. Give permissions to Apache.

$ cd /var/www/html
$ sudo wget https://download.nextcloud.com/server/releases/nextcloud-11.0.2.zip
$ sudo unzip nextcloud-11.0.2.zip
$ sudo chown -R www-data:www-data nextcloud

$ cd /var/www/html $ sudo wget https://download.nextcloud.com/server/releases/nextcloud-11.0.2.zip $ sudo unzip nextcloud-11.0.2.zip $ sudo chown -R www-data:www-data nextcloud

Setup Apache

$ sudo nano /etc/apache2/sites-available/nextcloud.conf
 
Alias / "/var/www/html/nextcloud/"
 
 Options +FollowSymlinks
 AllowOverride All
 
  Dav Off
 
 SetEnv HOME /var/www/html/nextcloud
 SetEnv HTTP_HOME /var/www/html/nextcloud

$ sudo nano /etc/apache2/sites-available/nextcloud.conf Alias / "/var/www/html/nextcloud/" Options +FollowSymlinks AllowOverride All Dav Off SetEnv HOME /var/www/html/nextcloud SetEnv HTTP_HOME /var/www/html/nextcloud

Enable Nextcloud. Disable default.

$ sudo a2ensite nextcloud.conf
$ sudo a2dissite 000-default.conf

$ sudo a2ensite nextcloud.conf $ sudo a2dissite 000-default.conf

Enable the following

$ sudo a2enmod rewrite
$ sudo a2enmod headers
$ sudo a2enmod env
$ sudo a2enmod dir
$ sudo a2enmod mime
$ sudo service apache2 restart

$ sudo a2enmod rewrite $ sudo a2enmod headers $ sudo a2enmod env $ sudo a2enmod dir $ sudo a2enmod mime $ sudo service apache2 restart

Open your browser and access your server via IP address or domain name to complete the NextCloud install.

You will be asked to enter a new username and password. Also enter your database credentials to complete the installation.

Working With AWS LightSail

Just a quick demo how to work with AWS LightSail. LightSail is AWS lightweight VPS at a fixed price point. You can install just the OS. You can choose either Amazon Linux or Ubuntu OS. If you prefer, you can install any of the several ready-made applications provided by AWS in conjunction with Bitnami. In this example, I installed Ubuntu and Apache just demonstrate how to easy it is to work with LightSail.

Nextcloud

Nextcloud is the next generation open source file storage and file synching platform. It’s similar to Dropbox, Google Drive and Microsoft OneDrive. The main difference is that you run the software on your own server. This is a perfect solution if you’re worried about mass surveillance. It’s safe enough to place on the cloud. Better yet, you can run it on your local network at home. It behaves somewhat similar to a NAS (Network Attached Storage) but with a better web interface, and a few more apps.

In addition, you can install the client software on your Desktop (PC, MAC and Linux) or to any mobile device (iOS, Android and Windows). The clients automatically sync data to the server software that’s installed on a Linux server. Files can also be accessed using WebDav as well. It has an online office, a video chat feature and Outlook email integration, but I’m not really interested with those additional features. I use it primarily for storage and file synching only. It works great by the way.

Give Nextcloud a try.
