Sciblog: A blog with the appearance of a scientific paper.
Blog developed in django with the same appearance of a research paper written in Latex.
- CSS and Latex fonts integrated
- Posts are presented in two columns like a paper
- Formulas can be added with Latex notation
- Share in social networks
- RSS feed
- Post search
- Blog optimized for SEO
- Comments with disqus
- Easy writing with Ckeditor
- Responsive for mobile
- (Optional) Web optimization with CloudFlare
- (Optional) Installation of free SSL certificate
Example of sciblog: https://miguelgfierro.com
We need to install several libraries. In Linux the commands are:
$ git clone https://github.com/miguelgfierro/sciblog.git $ apt-get install -y python-dev libpq-dev python-pip git apache2 libapache2-mod-wsgi $ pip install -r requirements.txt
NOTE: Django version must be 1.7 and Python has to be version 2.7.
Set up the project in localhost
The first step is to generate the database. In the project folder:
$ cp sciblog/private.template.py sciblog/private.py $ python manage.py syncdb
When you are in localhost you have to set
DEBUG = True in
sciblog/private.py. You can set it to
False but you won't see the images the user uploaded through the admin dashboard. In production, this is handled by apache. You should also change
Django will ask you to create a superuser. You have to put the username and password. The email is optional. This will generate a file called
db.sqlite3 which is the database where all the blog content is stored.
After that, you have to make a migration, to create the tables in your database. To do that:
$ python manage.py makemigrations $ python manage.py migrate
In another terminal you have to run django development server:
$ python manage.py runserver
In a browser put the link: http://localhost:8000/admin/
The panel will ask you to add username and password. Once you are in Django dashboard you can start adding content to your blog.
To work with disqus comments you have to get your
DISQUS_WEBSITE_SHORTNAME. They can be obtained at https://disqus.com/api/applications/.
Set up the project in a Ubuntu VPS server
First make sure that you have installed
libapache2-mod-wsgi as explained before. Also, change the key in
$ cd /var/www $ git clone https://github.com/miguelgfierro/sciblog.git $ cd sciblog $ cp sciblog/private.template.py sciblog/private.py $ python manage.py syncdb $ python manage.py makemigrations $ python manage.py migrate
Set the correct permissions:
$ chown www-data:www-data /var/www/sciblog $ chown www-data:www-data /var/www/sciblog/db.sqlite3 $ chown www-data:www-data /var/www/sciblog/img
Configure apache (in sciblog.conf change example.com for your url):
$ cp sciblog.conf /etc/apache2/sites-available/ $ a2ensite sciblog.conf $ a2enmod wsgi $ a2enmod rewrite $ a2enmod expires $ a2enmod headers $ a2enmod deflate $ service apache2 restart
When you are in production you have to set
DEBUG_FLAG = False in
Add your first content to the blog
The first step is to configure the site. Also, the first time you enter in your admin console http://localhost:8000/admin/, you have to go to sites and edit the default site, which is
example.com. Change it for
localhost:8000, if you are in development or to the name of your site without
http:// (my case would be miguelgfierro.com).
This will set the first entry in the database to your site, which is related to the variable
SITE_ID = 1 in
sciblog/settings.py. You can see the number of the site in http://localhost:8000/admin/sites/site/1/. If you add another site, then it will have a different number in the database, so for everything to work you have to change the variable
SITE_ID. In my experience, it is better if you don't touch anything :-)
Press add in Post to add your first post. You can add different sections, images and formulas. For images the recommended width is
300px. If you use a formula please select the flag
Post with Latex formula. This will load the necessary js module to render the Latex code. If the flag is not activated, then the js is not added to the template (we don't want extra page load if we are not using formulas, right?).
Create flat pages: generic page, about page and privacy page
Go to the admin console and add your first flat page. A flat page is a static html code.
In Flat pages press add. In url put
/about/ (don't forget / in both sides). In title put your name, in sites put your site, in content put whatever you want and finally in template name put
/privacy/. I created a policy that is compliant with GDPR and that contains the typical systems and services of a normal personal blog: Google Analytics, cookies, RSS, etc. The text that I use can be found here. You can adapt your policy to your specific blog.
In case you want to add more flat pages, there is a generic html template that you can customize by modifying the file default.html.
Managing mobile view
In order to debug with a mobile phone first you need to set
DEBUG = True in
sciblog/settings.py. Then you have to run the django server in the computer's external IP. To do that:
$ python manage.py runserver 0.0.0.0:8000
Then you need to know the IP of your computer. In Linux and Mac the command is
ifconfig, in Windows is
ipconfig. Then, to access your computer's server from a mobile phone, you have to open a browser in the phone and put the IP you just get. Let's assume the IP in my computer is 192.168.1.5, then you put in your mobile browser:
Secure page with SSL certificate (optional)
You can install a free SSL certificate with Let's Encript. Google prioritizes pages with SSL security, so https has became a key element for SEO. The first step is to set to True the flag
HTTPS in settings.py.
The basic installation in an apache server is very straightforward, as it is explained here. In the file sciblog.conf you have the configuration to activate the SSL. Furthermore, it allows to redirect http://example.com, https://example.com, http://www.example.com to https://example.com.
$ wget https://dl.eff.org/certbot-auto $ chmod a+x certbot-auto $ ./certbot-auto --apache --email firstname.lastname@example.org $ a2enmod ssl $ service apache2 restart
When the certificate expires, you just need to renew it.
$ ./certbot-auto renew --quiet --no-self-upgrade $ service apache2 restart
Once the SSL certificate is installed, you can check the security of your page using this web.
Automatize renewal of Let's Encrypt certificate
This task can be automated as Let's Encrypt explains in their web or you can use a CRON task.
I created a python script called cron_ssl_renew.py that allows one to automatize the SSL certificate renewal. To do it, you just have to execute the python script through crontab. Edit crontab with
crontab -e and add:
7 7 */5 * * (/bin/date && /usr/bin/python /var/www/sciblog/cron_ssl_renew.py) >> cron.log 2>&1
This files executes every 5 days at 7.07am (you can see the explanation here). You can see that the CRON task is correctly set up typing
crontab -l. Also, to make sure that the CRON job has run, you can type
grep "certbot-auto" /var/log/syslog.
Speed up page with Cloudflare (optional)
You can use Cloudflare to speed up your page and protect it. You just need to change the DNS. Don't forget to set the Cloudflare flag in
NOTE: if you decide to set the SSL certificate along with Cloudflare, it is better to pause Cloudflare while installing the SSL certificate to check that it is working correctly in your server. Later, you can resume CloudFlare and go to Crypto and set SSL to full strict. This process is automated in the script cron_ssl_renew.py.
This blog is automatically optimized for SEO, however, you can improve your visibility with these tricks:
- Always use https instead of http.
- Add your sitemap to Google, Bing and Yandex. For Baidu, it is difficult to index your site, in this url you can add your blog.
- Check the speed of your page with tools like GTmetrix, Pingdom or Google page speed.
- Promote your posts in sites like Hacker News, Reddit, Linkedin, Facebook or Twitter.
- Analyze your site on Google Analytics.
- Always use images in your posts, research shows that you will get more views.
- Engage with top influencers in your niche. You can feature other bloggers in your site and ask them to share or ask them to repost your content.
- Analyze your web with SEO checkers like Woorank or Semrush.
This is how my web looks like in terms of speed using GTmetrix:
