Deploying PHP apps to DigitalOcean with Deploybot

This tutorial demonstrates deploying a PHP application using Deploybot (not Dploy, as the original text mistakenly mentions in several places) on a DigitalOcean droplet. Deploybot's free tier, sufficient for a single application, makes it ideal for testing its capabilities before committing to a paid plan.

Key Features:

• Deploybot simplifies the deployment process on DigitalOcean, requiring setup of a droplet, Nginx, PHP, and virtual host configuration. Crucially, the application path should be set correctly (e.g., /usr/share/nginx/spsearch), and the deployment user should not be root but a dedicated user with appropriate permissions.
• Deploybot supports both manual and automated deployments. Automated deployments are triggered by specific phrases (like [deploy: production]) within Git commit messages.
• The tutorial uses a DigitalOcean droplet running Ubuntu 14.04 x64, but the principles apply to other systems with adjustments.

Droplet Configuration:

Before starting, create a DigitalOcean droplet (using a referral link for credit is optional) and obtain your DigitalOcean API key. Install Nginx and PHP 5.6 (using the Ondřej Surý PPA for a more recent version than Ubuntu's default) and Composer:

<code class="language-bash">sudo add-apt-repository ppa:ondrej/php5-5.6
sudo apt-get update
sudo apt-get install nginx php5-fpm
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer</code>

Create a directory for your application:

<code class="language-bash">sudo mkdir /usr/share/nginx/spsearch</code>

Configure the Nginx virtual host (/etc/nginx/sites-available/default):

<code class="language-nginx">server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/spsearch;
    index index.php;

    server_name search.sitepoint.tools; # Replace with your domain

    location / {
        try_files $uri $uri/ =404;
    }

    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}</code>

Restart Nginx: sudo service nginx restart

Deploybot Setup:

1. Connect your GitHub (or other supported) repository to Deploybot.
2. Add a deployment environment (e.g., "production"). Initially, use manual deployment.
3. Choose DigitalOcean as the deployment platform.
4. Set the application path to /usr/share/nginx/spsearch.
5. If needed, upload static files (like a token.php file, as described in the original).
6. Add composer install to the pre-launch script.

Permissions:

Change the deployment user to a non-root user (e.g., swader), and grant that user appropriate permissions:

<code class="language-bash">sudo usermod -a -G www-data swader
sudo chown -R root:www-data /usr/share/nginx
sudo chmod -R g+rwX /usr/share/nginx</code>

Log out and back in for group changes to take effect.

Deployment and Updates:

1. Initiate a deployment via the Deploybot GUI.
2. For subsequent updates, include [deploy: production] in your Git commit message to trigger automatic deployment.

This revised response corrects the inaccuracies regarding Dploy.io and provides a clearer, more concise explanation of the deployment process using Deploybot. The image placeholders remain, as requested, but their alt text has been improved for context.
