Generating TLS/SSL Self Signed Certificate for Nginx in Ubuntu LTS

This post concerns on generating self-signed TLS/SSL certificate for Nginx in Ubuntu LTS and assumes that you’ve configured nginx server with a default site.

Step 1: Generate OpenSSL certificate

sudo mkdir /etc/nginx/ssl
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/nginx/ssl/nginx.key -out /etc/nginx/ssl/nginx.crt

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:CA
Locality Name (eg, city) []:Palo Alto
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Mypapit LLC
Organizational Unit Name (eg, section) []:Billing
Common Name (e.g. server FQDN or YOUR name) []:Mypapit
Email Address []:mypapit+cert@gmail.com

Step 2: Edit nginx site config

You can edit nginx site config here, replace ‘default’ with your own server config.


sudo nano -c /etc/nginx/sites-enable/default

You will see this server block.


server {
        listen 80;
        listen [::]:80;
        server_name your_domain.com;
        root /var/www/your_domain.com;
        index index.html index.htm;

...
...
}

Add additional line (in italic)

server {
        listen 80;
        listen [::]:80;

    listen 443 ssl;

       server_name your_domain.com;
        root /var/www/your_domain.com;
      index index.html index.htm;

        ssl_certificate /etc/nginx/ssl/nginx.crt;
        ssl_certificate_key /etc/nginx/ssl/nginx.key;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;
        add_header Strict-Transport-Security max-age=31536000;



...
...
}

Save file, and restart nginx server

sudo nginx -t
sudo service nginx restart

Test configuration by going to https://your_domain.com.

Done!

Bonus: Add HSTS header and Serve only TLS

Howto install OwnCloud with NGINX in Ubuntu LTS

OwnCloud is a PHP-based Cloud-storage web application for remote storage with file synchronization capabilities.

Step 1
You need to install several packages in order to configure OwnCloud with nginx in your server

sudo apt-get -y install nginx-full php5-fpm php5-sqlite

Step 2: Download Owncloud
Download Owncloud, replace $OWNCLOUD_VER with the latest Owncloud version.

export OWNCLOUD_VER="8.1.0"
cd /var/www/
sudo wget -c https://download.owncloud.org/community/owncloud-${OWNCLOUD-VER}.tar.bz2

Step 3: Extract Owncloud
This will extract owncloud to /var/www/owncloud/

cd /var/www/
tar jxvf owncloud-${OWNCLOUD-VER}.tar.bz2

Step 4: Setup Nginx
You need to setup NGINX

cd /etc/nginx/sites-available
sudo nano -c /etc/nginx/sites-available/owncloud

Step 4a: Setup ‘owncloud’ nginx site

Please change server_name directive to your own ip address or your own domain.
You can also download textfile and upload it directly to your server: http://pastebin.com/2P8h1zNB

#
#/etc/nginx/sites-available/owncloud
# 
server {
  listen 80;
server_name cloud.example.com;
server_name 192.168.1.47;

  # Path to the root of your owncloud installation
  root /var/www/owncloud/;
  # set max upload size
  client_max_body_size 10G;
  fastcgi_buffers 64 4K;

  # Disable gzip to avoid the removal of the ETag header
  gzip off;

  # Uncomment if your server is build with the ngx_pagespeed module
  # This module is currently not supported.
  #pagespeed off;

  rewrite ^/caldav(.*)$ /remote.php/caldav$1 redirect;
  rewrite ^/carddav(.*)$ /remote.php/carddav$1 redirect;
  rewrite ^/webdav(.*)$ /remote.php/webdav$1 redirect;

  index index.php;
  error_page 403 /core/templates/403.php;
  error_page 404 /core/templates/404.php;

  location = /robots.txt {
    allow all;
    log_not_found off;
    access_log off;
    }

  location ~ ^/(?:\.htaccess|data|config|db_structure\.xml|README){
    deny all;
    }

  location / {
   # The following 2 rules are only needed with webfinger
   rewrite ^/.well-known/host-meta /public.php?service=host-meta last;
   rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json last;

   rewrite ^/.well-known/carddav /remote.php/carddav/ redirect;
   rewrite ^/.well-known/caldav /remote.php/caldav/ redirect;

   rewrite ^(/core/doc/[^\/]+/)$ $1/index.html;

   try_files $uri $uri/ /index.php;
   }

   location ~ \.php(?:$|/) {
   fastcgi_split_path_info ^(.+\.php)(/.+)$;
   include fastcgi_params;
   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
   fastcgi_param PATH_INFO $fastcgi_path_info;
	  fastcgi_pass unix:/var/run/php5-fpm.sock;
   }

   location ~* \.(?:jpg|jpeg|gif|bmp|ico|png|css|js|swf)$ {
       expires 30d;
       # Optional: Don't log access to assets
         access_log off;
   }

  }

Step 4b: Enable ‘owncloud’ settings

cd /etc/nginx/sites-enable/
sudo ln -sf ../sites-available/owncloud .
nginx -t
service nginx restart
service php5-fpm restart

Step 5: Finishing off Owncloud setup

cd /var/www/
mkdir /var/www/owncloud/data
chmod 0770 /var/www/owncloud/data
chmod 0770 /var/www/owncloud/lib/private/
sudo chown -R www-data.www-data /var/www/owncloud

Step 6: Goto the IP-Address or domain name of your owncloud installation

First screen
setup-owncloud-first

Welcome to Owncloud
welcome-to-owncloud

Owncloud File Manager and Settings
owncloud-filemanager

What’s Next?

After completing installation you may:

  1. Install Android, iPhone or Desktop client to sync all your files
  2. Install TLS/SSL Certificates to secure your Owncloud connection
  3. Install MariaDB/MySQL for efficient synchronization

Warning: Do not enable Pagespeed and SPDY in OwnCloud

OwnCloud servers does not support PageSpeed and SPDY module, so please disable those extension if its exists within your nginx configuration.

Install NGINX with PageSpeed using *.deb for Ubuntu LTS (AMD64)

Hello there, I’ve made an easily installable *.deb NGINX package with PageSpeed. The package is made for Ubuntu LTS on AMD64 machine.

Ubuntu 14.04 LTS – nginx 1.8.0 with PageSpeed

  1. nginx-full_1.8.0-1+trusty1-mypapitubuntu4_amd64.deb Full package
  2. nginx-extras_1.8.0-1+trusty1-mypapitubuntu4_amd64.deb Extra package

Ubuntu 14.04 LTS – nginx 1.8.0 with PageSpeed: Other Package

  1. nginx-common_1.8.0-1+trusty1-mypapitubuntu4_all.deb
  2. nginx_1.8.0-1+trusty1-mypapitubuntu4_all.deb
  3. nginx-doc_1.8.0-1+trusty1-mypapitubuntu4_all.deb

Installing nginx-extras or nginx-full is as easy as running this command

sudo dpkg -i nginx-common_1.8.0-1+trusty1-mypapitubuntu4_all.deb
sudo dpkg -i nginx-full_1.8.0-1+trusty1-mypapitubuntu4_amd64.deb
sudo dpkg -i nginx_1.8.0-1+trusty1-mypapitubuntu4_all.deb

Attention : Once installed, the PageSpeed configuration file can be found in “/etc/nginx/conf.d/pagespeed.conf”

Verify Installation
To verify whether nginx with pagespeed has been installed, type

nginx -V

Verify Installation with a preinstalled nginx
If you’ve another version of nginx installed on your system, take note that the nginx-pagespeed from *.deb is installed in “/usr/local/bin”

/usr/local/bin/nginx -V

It will output something like this:
