Install Sendy on a Subdirectory with Nginx and Virtualmin

Nginx rewrite rules for Sendy on a subdirectory with WordPress on document root

I’ve previously covered installing Sendy on an Ubuntu 16.04 VPS with nginx and Virtualmin. That tutorial works for both domains and subdomains, if installing Sendy on public_html directory. What if someone what to install Sendy on a subdirectory? That tutorial doesn’t work for that. But this tutorial will show you how to install Sendy on a subdirectory with Nginx and Virtualmin.

The reason that tutorial doesn’t work is due to nginx rewrite rules. Nginx rewrite rules on that tutorial doesn’t work for subdirectories. The installation process is similar. But we’ll upload Sendy files to a subdirectory instead of public_html directory. And there is a slight difference in nginx rewrite rules which makes it all work. So let’s install Sendy on a subdirectory with Nginx.

Prerequisites

These prerequisites are for a fresh server setups. I know there is a good chance you’ve already configured your VPS following one of my previous tutorials. In that case you can skip to the next section. And for the people who’s starting fresh, you need to get a Ubuntu 16.04 VPS and perform following tasks to prepare your server for sendy.

Completing above steps will configure your VPS with Virtualmin v6.03 GPL, Nginx v1.10.3, PHP v7.0.30 and MySQL v5.7.23. This setup is known as LEMP. I highly recommend completing all steps whether they are optional or not. You may also install WordPress or any other software on document root prior to installing Sendy. But that can be done later too.

Upload Sendy to the Server

We’ll start by creating a directory inside public_html to hold Sendy. I’ll call this directory email. So login to your VPS as domain admin user and create a directory named email with this command.

mkdir $HOME/public_html/email

Now connect to your server with Filezilla and upload Sendy files to the directory you just created. Remember to use domain admin user for this as well. Using root account will result in permission errors later on.

Create a MySQL database for Sendy

Virtualmin automatically creates a MySQL database for each virtual server you create. But it’s not going to be enough for us here since we’re hosting two apps on same virtual server. Fortunately, creating a new database is easy with Virtualmin. Login to Virtualmin and select your domain. And then click ‘Edit Databases’. From there, you’ll see a button to create a new database.
Virtualmin Additional MySQL Database
This will create a new MySQL database for the selected domain. Both databases will have user assigned to them. Which is the domain’s admin user.

Prepare Sendy for Installation

Now that everything is ready on the server, we need to make some changes to Sendy config.php file. This is the file that holds MySQL credentials. Open Sendy config.php with nano text editor.

nano /home/AdminUser/public_html/email/includes/config.php

Search for following line and replace your_sendy_installation_url with your domain name.

define('APP_PATH', 'https://example.com/email');

Then search for following lines and add database credentials within apostrophe marks. You can get MySQL database credentials from Virtualmin.

	$dbHost = ''; //MySQL Hostname
	$dbUser = ''; //MySQL Username
	$dbPass = ''; //MySQL Password
	$dbName = ''; //MySQL Database Name

Close the file with Ctrl+X keys. Now change permissions of the uploads directory to 777.

chmod -R 777 /home/AdminUser/public_html/email/uploads

Add nginx Rewrite Rules for Sendy on Subdirectory

Open virtual host file for the domain with nano text editor. Replace example.com with your domain or sub domain. You need to be logged in as root for this part.

nano /etc/nginx/sites-available/example.com.conf

Search for following line,

fastcgi_param HTTPS $https;

And paste following rules below it in a new line.

location ^~ /email {
root /home/AdminUser/public_html/;
     error_log /var/log/nginx/sendy.error.log;
     index index.php index.html index.htm;
     try_files $uri $uri/ $uri.php?$args;
     rewrite ^/email/w/([a-zA-Z0-9/]+)$ /email/w.php?i=$1 last;
     rewrite ^/email/l/([a-zA-Z0-9/]+)$ /email/l.php?i=$1 last;
     rewrite ^/email/t/([a-zA-Z0-9/]+)$ /email/t.php?i=$1 last;
     rewrite ^/email/subscribe/([a-zA-Z0-9/]+)$ /email/subscribe.php?i=$1 last;
     rewrite ^/email/unsubscribe/([a-zA-Z0-9/]+)$ /email/unsubscribe.php?i=$1 last;
     location ~ \.php$ {
              try_files $uri =404;
              fastcgi_pass unix:/var/php-nginx/XXXXXXXXXXXXXX.sock/socket;
     }
}

Now before you save this file, there are couple of changes you should make. First you need to change the AdminUser. Then change the email if you used a different directory. Finally change XXXXXXXXXXXXXX with your socket number. You can find this number within the same file. This is how file should look like after making changes. Note the socket number.
nginx Rewrite Rules for Sendy on Subdirectory

Close the file and restart nginx.

systemctl restart nginx.service

Install Sendy on a Subdirectory with nginx

Sendy should be ready to be installed now. You can run the compatibility check to see if you’re setup everything properly. Compatibility check script is available from,

http://example.com/email/_compatibility.php?i=1
The 8/9 score is due to mod_rewrite is being disabled. mod_rewrite is an Apache module and therefore not enabled on your server. Since you’ve already added nginx rewrite rules to the server, mod_rewrite is not required to run Sendy. The compatibility check script only check for availability of mod_rewrite. Sendy will run normally without it.

Now open your Sendy URL on browser. You’ll see a page similar to this image.
install sendy on VPS
Follow the instructions on that page to complete the Sendy installation. Once you do that Sendy installation is complete for the most part. But Sendy requires Cron jobs set up for campaign scheduling and autoresponders.

Setup Sendy Cron Jobs

Virtualmin gives a nice GUI to create and manage cronjobs at Webmin > System > Scheduled Cron Jobs. But I find it easier to do it from command line. So login to your VPS as domain admin user and execute following command.

crontab -e

You’ll be asked to select an editor if this is your first time editing crontab. Select the easiest option which is Nano. Then add following rules towards the end of the file.

*/5 * * * * php /home/AdminUser/public_html/email/scheduled.php > /dev/null 2>&1
*/1 * * * *  php /home/AdminUser/public_html/email/autoresponders.php > /dev/null 2>&1

These two rules execute commands for Sendy campaign scheduler and Sendy autoresponder. Autoresponder is called every minute and scheduler is called every 5 minutes. Close the file. Your Sendy should be fully configured now.

If you have issues with these instructions or the installation create a topic on server administration forum.
