This guide will help us deploy a flask application on a VPS via SSH. There are several ways to deploy python based apps but in this case, we will use Apache and Phusion Passenger \u2013 the same software used in shared hosting.<\/p>\n
The steps involved are as follows:<\/p>\n
1.Install needed software (Python3, Apache, Passenger and Git)<\/p>\n
2.Upload you website<\/p>\n
3.Setup server configuration<\/p>\n
Lets get started<\/p>\n
The software needed are python3, Apache, Passenger and Git<\/p>\n
Uninstall Python 2<\/p>\n
$ sudo apt remove python2<\/pre>\n$ sudo apt remove python-is-python2<\/pre>\n$ sudo apt autoremove --purge<\/pre>\nInstall Python 3<\/p>\n
$ sudo apt-get update<\/pre>\n$ sudo apt-get install -y python3 python3-pip<\/pre>\nInstall Apache<\/p>\n
$ sudo apt-get install apache2<\/pre>\nInstall Passenger and needed Apache modules<\/p>\n
$ sudo apt-get install -y dirmngr gnupg\r\n$ sudo apt-key adv --keyserver hkp:\/\/keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7\r\n$ sudo apt-get install -y apt-transport-https ca-certificates\r\n$ sudo apt-get install -y libapache2-mod-passenger\r\n$ sudo a2enmod passenger\r\n$ systemctl restart apache2<\/pre>\nInstall Git<\/p>\n
$ sudo apt-get install -y git<\/pre>\nUpload your website<\/h2>\n
We will use git to upload our website. To do this, you need to have your website already available in a repo such as Github or Gitlab.<\/p>\n
Create a user for your app. We will call our user\u00a0appuser<\/strong><\/p>\n
$ useradd appuser<\/pre>\n$ passwd appuser<\/pre>\nCreate your application directory<\/p>\n
$ sudo mkdir -p \/var\/www\/awesomeapp<\/pre>\n$ sudo chown appuser: \/var\/www\/awesomeapp<\/pre>\nClone your app<\/p>\n
$ cd \/var\/www\/awesomeapp && sudo -u appuser -H git clone https:\/\/gitlab.com\/username\/awesomeapp.git<\/pre>\nNote<\/strong>: If you do not have an app in a repo such as Github or Gitlab already, please manually upload your app files to
\/var\/www\/awesomeapp<\/code><\/p>\nSetup server configuration<\/h2>\n
The next thing is to complete the set up of our app. This means we install the application requirements and configure Apache<\/p>\n
Install app requirements<\/p>\n
Your app should have a requirements.txt file. Run the command below to install required files<\/p>\n
$ pip3 install -r requirements.txt<\/pre>\nCreate an Apache VHOST file using the following command. We\u2019ll assume your domain is called truehosttestdomain.com<\/p>\n
$ sudo vim \/etc\/apache2\/sites-enabled\/awesomeapp.conf<\/pre>\nCopy the content below<\/p>\n
<VirtualHost *:80>\r\n ServerAdmin webmaster@truehosttestdomain.com\r\n ServerName truehosttestdomain.com\r\n ServerAlias truehosttestdomain.com\r\n \r\n # Tell Apache and Passenger where your app's code directory is\r\n DocumentRoot \/var\/www\/awesomeapp\/code\/\r\n PassengerAppRoot \/var\/www\/awesomeapp\/code\r\n \r\n # Tell Passenger that your app is a Python app\r\n PassengerAppType wsgi\r\n PassengerStartupFile passenger_wsgi.py\r\n \r\n ErrorLog \/var\/www\/truehosttestdomain.com\/logs\/error.log\r\n CustomLog \/var\/www\/truehosttestdomain.com\/logs\/access.log combined\r\n \r\n Alias \/static\/ \/var\/www\/awesomeapp\/static\r\n <Directory \/var\/www\/awesomeapp\/static>\r\n Order allow,deny\r\n Allow from all\r\n <\/Directory>\r\n \r\n<\/VirtualHost>\r\n<\/code><\/pre>\nRestart apache and check your domain online!<\/p>\n
