Ghost Blog Auto Setup with Nginx and Naxsi

Ghost is a simple, modern WordPress alternative which puts the excitement back into blogging. It is beautifully designed, easy to use, completely open source, and free for everyone. Ghost can be run behind Nginx (as a reverse proxy) with Naxsi for better performance and security. This blog is proudly published using Ghost.

Naxsi Logo

"Naxsi is an open source, high performance, low rules maintenance, Web Application Firewall module for Nginx, the infamous web server and reverse-proxy. Its goal is to help people securing their web applications against attacks like SQL Injections, Cross Site Scripting, Cross Site Request Forgery, Local & Remote file inclusions."
  - From the NAXSI Project (GitHub).

To the best of my knowledge, this tutorial is the first to discuss how to install Ghost blog with both Nginx and Naxsi. To keep things simple, I will link to other guides on the web where appropriate.

Getting a VPS

Before installing Ghost, you need to get a virtual private server (VPS) which can run Linux. A minimum of 512MB RAM is recommended.

DigitalOcean is the provider that I use. DigitalOcean also provides a pre-built Ghost app.

Install and Configure Ghost

Note: Users upgrading their Ghost blog, follow these steps.

An excellent guide named Dude looks like a Ghost outlines the process of installing Ghost with ModSecurity. Most of the steps can be re-used for Naxsi. For your convenience, I have compiled everything into this fully automated setup script, after adding important fixes and optimizations. It can be used with Ubuntu LTS, Debian 9/8 and CentOS 7/6. You may install multiple blogs on the same server.

Link to the script:

I try to keep the software versions up-to-date in the script above. For your information, the latest releases can be found at:

Ghost blog: Check for new versions at
Nginx: Official download page:

Users who prefer ModSecurity over Naxsi, see my other tutorial.

Documentations for Naxsi, including how to configure whitelists and set up learning tools, can be found at this official wiki.

Set Up HTTPS for Your Blog

You can get a FREE SSL certificate and set up HTTPS for your blog!

Let’s Encrypt is a new Certificate Authority (CA) that is free, automated, and open. Sponsored by major companies such as Mozilla, Cisco and Facebook, Let's Encrypt is officially leaving beta on April 12, 2016.

Here is a list of client implementations for Let's Encrypt. Besides the official client, the more popular ones include Get HTTPS for Free, No Sudo Client, Simp LE and ACME Tiny. Read the documentation, visit the community, and check out this tutorial. It is worth mentioning that the Caddy web server, written in Go, has built-in support for Let's Encrypt.

StartCom is another well-known CA providing free SSL certificates. To get started, follow this guide. Note that the step(s) to generate your private key and Certificate Signing Request (CSR) can be simplified to:

openssl req -new -newkey rsa:2048 -nodes \

The output file YOUR.DOMAIN.NAME.csr will contain your CSR. Continue with the guide above, and at the "Submit CSR" page, copy that file's content and paste into the text box. Proceed with the remaining steps, and follow the official instructions to install the certificate. For security, make sure your private key YOUR.DOMAIN.NAME.pem is only readable by root.

Sitemap, Robots.txt and Extras

Note: Newer Ghost blog versions now automatically generate a sitemap and robots.txt. If you wish to instead create and use your own files, uncomment the corresponding location block in nginx-blog1.conf and restart Nginx.

To generate a sitemap for your blog, look at Ghost sitemap generator, which provides a script for this. Change url to your blog's domain name, and if you followed the first guide above, you need to edit webroot to e.g. /var/www/YOUR.DOMAIN.NAME/public (create that public folder first). After running the script, your sitemap.xml will be generated inside it.

Adding robots.txt to your site is easy. A basic example is:

User-agent: *  
Disallow: /ghost/  
Disallow: /signout/  
Sitemap: http://YOUR.DOMAIN.NAME/sitemap.xml  

Put this file under /var/www/YOUR.DOMAIN.NAME/public. Refer to my nginx.conf below. The same config block can also be used for site verification html files from e.g. Google Webmaster Tools, just place them under public and add the filenames to that location regex.

There's a nice trick to let your blog's links open in a new tab or window, just add " target="_blank before the closing ). In addition, if you want to add Disqus comments to your posts, see this guide by Christoph Voigt. Browse to this post by George Liu for how to load comments on demand as well as add comment counts to post titles.

Want to add Google Analytics to your blog? It's easy. After signing up to get tracking code, edit the file content/themes/casper/default.hbs and put it just before the </head> tag, then restart Ghost. Also want to track outbound links that your visitors click on your blog pages? No problem, see this great how-to. To use that code "inline", remember to wrap it in <script>...</script> tags.

Finally, if you use DigitalOcean to host your blog, learn how to set up your hostname or domain with DigitalOcean's DNS.

My Nginx Configuration

An example nginx.conf is shown below. To save it, click on "view raw" at bottom-right corner, Ctrl-A to select all, Ctrl-C to copy, then paste into your favorite editor. Remember to replace every YOUR.DOMAIN.NAME with your blog's full domain name. If you don't need SSL, comment out listen 443 and all lines starting with ssl_.

Also, here is the actual Nginx configuration for this blog, using ModSecurity instead of Naxsi. This is for your reference only.

Setting Up E-Mail on Ghost

To configure email, read the official instructions. Remember to restart Ghost. If using Amazon SES, try this alternative configuration (credit):

mail: {  
    transport: 'SMTP',
 // For a list of all Amazon SES SMTP endpoints, see:
    host: 'ssl://',
    options: {
        port: 465,
        service: 'SES',
        auth: {
            user: 'YOUR_SES_SMTP_CREDENTIAL_ID',

Upgrading Your Ghost Blog

To upgrade your Ghost blog, see: How to upgrade Ghost blog.

Follow the instructions below ONLY IF you had used my script to install Ghost. Replace every YOUR.DOMAIN.NAME with your actual domain name.

# Stop running Ghost process  
su - ghost -s /bin/bash  
forever stopall  
# Make a Backup. VERY IMPORTANT! cd /var/www/ cp --archive YOUR.DOMAIN.NAME YOUR.DOMAIN.NAME-OLD
# Create temp dir, download the ghost source and unzip cd YOUR.DOMAIN.NAME mkdir temp cd temp/ wget unzip
# Replace files and set correct owners cp *.js *.json *.md LICENSE ../ cd .. chown ghost:ghost *.js *.json *.md LICENSE rm -rf core cp -R temp/core ./ chown -hR ghost:ghost core rm -rf content/themes/casper cp -R temp/content/themes/casper content/themes/ chown -hR ghost:ghost content/themes/casper

Not done yet! Now is a good time to go into your YOUR.DOMAIN.NAME-OLD backup folder and look for files you had customized before, e.g. files in content/themes/casper. Manually add those customizations to your new Ghost install in YOUR.DOMAIN.NAME. Then edit the config file config.js as needed. When finished, proceed with upgrading Ghost:

# Upgrade Ghost  
su - ghost -s /bin/bash  
cd /var/www/YOUR.DOMAIN.NAME/  
npm install --production
# If you see no error, start Ghost blog process ./ exit
# Remove temporary dir when finished rm -rf /var/www/YOUR.DOMAIN.NAME/temp

Congratulations! You have successfully upgraded your Ghost blog.
