Perhaps the most popular and most widely used of all the VPS providers out there, DigitalOcean provides a range of VPS options. Starting at $5/mo for a 1 CPU, 1024MB system up to $960/mo for a 32 CPU, 192GB setup, DigitalOcean has solutions that can scale with you. All their servers are built with RAID SSD drives, modern hexa-core hardware, KVM Virtualization, and reliable Tier-1 bandwidth to ensure maximum performance. They are a fantastic option for hosting your Grav-based site.
After creating an account and depositing some credit into it, you can get started. DigitalOcean let's you create Droplets that represent a VPS instance. You simple click the Create Droplet button in your Control Panel, and fill in the form:
Simply pick a name for your Droplet, and choose a size based on price and server needs. Grav will run fine on any configuration even the base $5/mo option will run Grav quickly and efficiently.
Next, select a Region where your VPS will be located. It's best to pick a region that is going to serve your target audience the best. If the server is for development purposes only, pick one that is located closest to you.
Lastly you will need to select an Image to install. DigitalOcean lets you choose from a wide variety of stock Linux distributions, as well as complete Applications and even prior saved snapshots. For the purpose of this guide, we'll install the latest Ubuntu 18.04 LTS which is very popular and very well supported.
You can leave all the other options at their defaults. After clicking Create Droplet your Droplet will be created within 55 seconds, and you will see it listed in your list of Droplets. You should receive an email with your root password. Clicking on the Droplet you just created you will see various options.
The Access tab in the Droplet Manager allows you to quickly log on to your instance, but using SSH is a more enjoyable experience. Public key authentication is also recommended, and DigitalOcean has great SSH public key authentication documentation that walks you through the steps required.
At this point, you might want to either setup a local /etc/hosts
entry to give the IP provided a nice friendly name such as digitalocean.dev
. That way you can more easily SSH to your server with ssh [email protected]
.
After successfully SSH'ing to your server as root, the first thing you will want to do is update and upgrade all the installed packages. This will ensure you are running the latest-and-greatest:
[prism classes="language-bash command-line"]
[/prism]
Just answer Y
if prompted.
Before we go any further, let's remove Apache2 which we will replace with Nginx:
[prism classes="language-bash command-line"]
[/prism]
NOTE: You might not have this installed. But better safe than sorry!
Next you will want to install some essential packages:
[prism classes="language-bash command-line"]
[/prism]
This will install the complete VIM editor (rather than the mini version that ships with Ubuntu), Nginx web server, GIT commands, and PHP 7.2.
Once php-fpm is installed, there is a slight configuration change that needs to take place for a more secure setup.
[prism classes="language-bash command-line"]
[/prism]
Search for cgi.fix_pathinfo
. This will be commented out by default and set to '1'.
This is an extremely insecure setting because it tells PHP to attempt to execute the closest file it can find if the requested PHP file cannot be found. This basically would allow users to craft PHP requests in a way that would allow them to execute scripts that they shouldn't be allowed to execute.
Uncomment this line and change '1' to '0' so it looks like this
[prism classes="language-bash command-line"] cgi.fix_pathinfo=0 [/prism]
Save and close the file, and then restart the service.
[prism classes="language-bash command-line"]
[/prism]
Nginx has already been installed, but you should configure is so that it uses a user-specific PHP connection pool. This will ensure you are secure and avoid any potential file permissions when working on the files as your user account, and via the web server.
Navigate to the pool directory and create a new grav
configuration:
[prism classes="language-bash command-line"]
[/prism]
In Vim, you can paste the following pool configuration:
[prism classes="language-apache line-numbers"] [grav]
user = grav group = grav
listen = /var/run/php/php7.2-fpm.sock
listen.owner = www-data listen.group = www-data
pm = dynamic pm.max_children = 5 pm.start_servers = 2 pm.min_spare_servers = 1 pm.max_spare_servers = 3
chdir = / [/prism]
The key things here are the user
and group
being set to a user called grav
, and the listen socket having a unique name from the standard socket. Save and exit this file.
We need to create the dedicated grav
user now:
[prism classes="language-bash command-line"]
[/prism]
Provide a strong password, and leave the other values as default. We need to next create an appropriate location for Nginx to serve files from, so let's switch user and create those folder, and create a couple of test files:
[prism classes="language-bash command-line"]
$ mkdir -p www/html $ cd www/html [/prism]
Create a simple index.html
with the contents of:
[prism classes="language-html"]
[/prism]
..and a file called info.php
with the contents of:
[prism classes="language-php"] <?php phpinfo(); [/prism]
Now we can exit out of this user and return to root in order to setup the Nginx server configuration:
[prism classes="language-bash command-line"] $ exit
[/prism]
Then simply paste in this configuration:
[prism classes="language-nginx line-numbers"] server {
index index.html index.php;
## Begin - Server Info
root /home/grav/www/html;
server_name localhost;
## End - Server Info
## Begin - Index
# for subfolders, simply adjust:
# `location /subfolder {`
# and the rewrite to use `/subfolder/index.php`
location / {
try_files $uri $uri/ /index.php?$query_string;
}
## End - Index
## Begin - Security
# deny all direct access for these folders
location ~* /(\.git|cache|bin|logs|backup|tests)/.*$ { return 403; }
# deny running scripts inside core system folders
location ~* /(system|vendor)/.*\.(txt|xml|md|html|yaml|yml|php|pl|py|cgi|twig|sh|bat)$ { return 403; }
# deny running scripts inside user folder
location ~* /user/.*\.(txt|md|yaml|yml|php|pl|py|cgi|twig|sh|bat)$ { return 403; }
# deny access to specific files in the root folder
location ~ /(LICENSE\.txt|composer\.lock|composer\.json|nginx\.conf|web\.config|htaccess\.txt|\.htaccess) { return 403; }
## End - Security
## Begin - PHP
location ~ \.php$ {
# Choose either a socket or TCP/IP address
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
# fastcgi_pass unix:/var/run/php5-fpm.sock; #legacy
# fastcgi_pass 127.0.0.1:9000;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;
}
## End - PHP
} [/prism]
This is the stock nginx.conf
file that comes with Grav with 2 changes. 1) the root
has been adapted to our user/folder we just created and the fastcgi_pass
option has been set to the socket we defined in our grav
pool. Now we just need to link this file appropriately so that it's enabled:
[prism classes="language-bash command-line"]
[/prism]
You can test the configuration with the command nginx -t
. It should return the following.
[prism classes="language-bash command-line"] nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful [/prism]
Now all we have to do is restart Nginx and the php7-fpm process and test to ensure we have configured Nginx and the PHP connection pool correctly:
[prism classes="language-bash command-line"]
[/prism]
Now point your browser at your server: http://digitalocean.dev
and you should see the text: Working!
You can also test to ensure that PHP is installed and working correctly by pointing your browser to: http://digitalocean.dev/info.php
. You should see a standard PHP info page with APCu, Opcache, etc listed.
This is the easy part! First we need to jump back over to the Grav user, so either SSH as [email protected]
or su - grav
from the root login. then follow these steps:
[prism classes="language-bash command-line"] $ cd ~/www $ wget -O grav.zip https://getgrav.org/download/core/grav/latest $ unzip grav.zip $ rm -Rf html $ mv grav html [/prism]
Now That's done you can confirm Grav is installed by pointing your browser to http://digitalocean.dev
and you should be greeted with the Grav is Running! page.
Because you have followed these instructions diligently, you will also be able to use the Grav CLI and Grav GPM commands such as:
[prism classes="language-bash command-line"] $ cd ~/www/html $ bin/grav clear
Clearing cache
Cleared: cache/twig/ Cleared: cache/compiled/
Touched: /home/grav/www/html/user/config/system.yaml [/prism]
and GPM commands:
[prism classes="language-bash command-line"] $ bin/gpm index [/prism]
