+<h1>Manual upgrade procedure for Zeppelin</h1>
+
+<div id="toc"></div>
+
+<p>Basically, newer version of Zeppelin works with previous version notebook directory and configurations.
+So, copying <code>notebook</code> and <code>conf</code> directory should be enough.</p>
+
+<h2>Instructions</h2>
+
+<ol>
+<li>Stop Zeppelin: <code>bin/zeppelin-daemon.sh stop</code></li>
+<li>Copy your <code>notebook</code> and <code>conf</code> directory into a backup directory</li>
+<li>Download newer version of Zeppelin and Install. See <a href="../../quickstart/install.html#install">Install Guide</a>.</li>
+<li>Copy backup <code>notebook</code> and <code>conf</code> directory into newer version of Zeppelin <code>notebook</code> and <code>conf</code> directory</li>
+<li>Start Zeppelin:  <code>bin/zeppelin-daemon.sh start</code></li>
+</ol>
+
+<h2>Migration Guide</h2>
+
+<h3>Upgrading from Zeppelin 0.7 to 0.8</h3>
+
+<ul>
+<li>From 0.8, we recommend to use <code>PYSPARK_PYTHON</code> and <code>PYSPARK_DRIVER_PYTHON</code> instead of <code>zeppelin.pyspark.python</code> as <code>zeppelin.pyspark.python</code> only effects driver. You can use <code>PYSPARK_PYTHON</code> and <code>PYSPARK_DRIVER_PYTHON</code> as using them in spark.</li>
+<li>From 0.8, depending on your device, the keyboard shortcut <code>Ctrl-L</code> or <code>Command-L</code> which goes to the line somewhere user wants is not supported. </li>
+</ul>
+
+<h3>Upgrading from Zeppelin 0.6 to 0.7</h3>
+
+<ul>
+<li>From 0.7, we don&#39;t use <code>ZEPPELIN_JAVA_OPTS</code> as default value of <code>ZEPPELIN_INTP_JAVA_OPTS</code> and also the same for <code>ZEPPELIN_MEM</code>/<code>ZEPPELIN_INTP_MEM</code>. If user want to configure the jvm opts of interpreter process, please set <code>ZEPPELIN_INTP_JAVA_OPTS</code> and <code>ZEPPELIN_INTP_MEM</code> explicitly. If you don&#39;t set <code>ZEPPELIN_INTP_MEM</code>, Zeppelin will set it to <code>-Xms1024m -Xmx1024m -XX:MaxPermSize=512m</code> by default.</li>
+<li>Mapping from <code>%jdbc(prefix)</code> to <code>%prefix</code> is no longer available. Instead, you can use %[interpreter alias] with multiple interpreter setttings on GUI.</li>
+<li>Usage of <code>ZEPPELIN_PORT</code> is not supported in ssl mode. Instead use <code>ZEPPELIN_SSL_PORT</code> to configure the ssl port. Value from <code>ZEPPELIN_PORT</code> is used only when <code>ZEPPELIN_SSL</code> is set to <code>false</code>.</li>
+<li>The support on Spark 1.1.x to 1.3.x is deprecated.</li>
+<li>From 0.7, we uses <code>pegdown</code> as the <code>markdown.parser.type</code> option for the <code>%md</code> interpreter. Rendered markdown might be different from what you expected</li>
+<li>From 0.7 note.json format has been changed to support multiple outputs in a paragraph. Zeppelin will automatically convert old format to new format. 0.6 or lower version can read new note.json format but output will not be displayed. For the detail, see <a href="http://issues.apache.org/jira/browse/ZEPPELIN-212">ZEPPELIN-212</a> and <a href="https://github.com/apache/zeppelin/pull/1658">pull request</a>.</li>
+<li>From 0.7 note storage layer will utilize <code>GitNotebookRepo</code> by default instead of <code>VFSNotebookRepo</code> storage layer, which is an extension of latter one with versioning capabilities on top of it.</li>
+</ul>

+<h1>Authentication for NGINX</h1>
+
+<div id="toc"></div>
+
+<p><a href="./shiro_authentication.html">Build in authentication mechanism</a> is recommended way for authentication. In case of you want authenticate using NGINX and <a href="https://en.wikipedia.org/wiki/Basic_access_authentication">HTTP basic auth</a>, please read this document.</p>
+
+<h2>HTTP Basic Authentication using NGINX</h2>
+
+<blockquote>
+<p><strong>Quote from Wikipedia:</strong> NGINX is a web server. It can act as a reverse proxy server for HTTP, HTTPS, SMTP, POP3, and IMAP protocols, as well as a load balancer and an HTTP cache.</p>
+</blockquote>
+
+<p>So you can use NGINX server as proxy server to serve HTTP Basic Authentication as a separate process along with Zeppelin server.
+Here are instructions how to accomplish the setup NGINX as a front-end authentication server and connect Zeppelin at behind.</p>
+
+<p>This instruction based on Ubuntu 14.04 LTS but may work with other OS with few configuration changes.</p>
+
+<ol>
+<li><p>Install NGINX server on your server instance</p>
+
+<p>You can install NGINX server with same box where zeppelin installed or separate box where it is dedicated to serve as proxy server.</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="nv">$ </span>apt-get install nginx
+</code></pre></div>
+<blockquote>
+<p><strong>NOTE :</strong> On pre 1.3.13 version of NGINX, Proxy for Websocket may not fully works. Please use latest version of NGINX. See: <a href="https://www.nginx.com/blog/websocket-nginx/">NGINX documentation</a>.</p>
+</blockquote></li>
+<li><p>Setup init script in NGINX</p>
+
+<p>In most cases, NGINX configuration located under <code>/etc/nginx/sites-available</code>. Create your own configuration or add your existing configuration at <code>/etc/nginx/sites-available</code>.</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="nv">$ </span><span class="nb">cd</span> /etc/nginx/sites-available
+<span class="nv">$ </span>touch my-zeppelin-auth-setting
+</code></pre></div>
+<p>Now add this script into <code>my-zeppelin-auth-setting</code> file. You can comment out <code>optional</code> lines If you want serve Zeppelin under regular HTTP 80 Port.</p>
+<div class="highlight"><pre><code class="text language-text" data-lang="text">upstream zeppelin {
+    server [YOUR-ZEPPELIN-SERVER-IP]:[YOUR-ZEPPELIN-SERVER-PORT];   # For security, It is highly recommended to make this address/port as non-public accessible
+}
+
+# Zeppelin Website
+server {
+    listen [YOUR-ZEPPELIN-WEB-SERVER-PORT];
+    listen 443 ssl;                                      # optional, to serve HTTPS connection
+    server_name [YOUR-ZEPPELIN-SERVER-HOST];             # for example: zeppelin.mycompany.com
+
+    ssl_certificate [PATH-TO-YOUR-CERT-FILE];            # optional, to serve HTTPS connection
+    ssl_certificate_key [PATH-TO-YOUR-CERT-KEY-FILE];    # optional, to serve HTTPS connection
+
+    if ($ssl_protocol = &quot;&quot;) {
+        rewrite ^ https://$host$request_uri? permanent;  # optional, to force use of HTTPS
+    }
+
+    location / {    # For regular websever support
+        proxy_pass http://zeppelin;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header Host $http_host;
+        proxy_set_header X-NginX-Proxy true;
+        proxy_redirect off;
+        auth_basic &quot;Restricted&quot;;
+        auth_basic_user_file /etc/nginx/.htpasswd;
+    }
+
+    location /ws {  # For websocket support
+        proxy_pass http://zeppelin/ws;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade websocket;
+        proxy_set_header Connection upgrade;
+        proxy_read_timeout 86400;
+    }
+}
+</code></pre></div>
+<p>Then make a symbolic link to this file from <code>/etc/nginx/sites-enabled/</code> to enable configuration above when NGINX reloads.</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="nv">$ </span>ln -s /etc/nginx/sites-enabled/my-zeppelin-auth-setting /etc/nginx/sites-available/my-zeppelin-auth-setting
+</code></pre></div></li>
+<li><p>Setup user credential into <code>.htpasswd</code> file and restart server</p>
+
+<p>Now you need to setup <code>.htpasswd</code> file to serve list of authenticated user credentials for NGINX server.</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="nv">$ </span><span class="nb">cd</span> /etc/nginx
+<span class="nv">$ </span>htpasswd -c htpasswd <span class="o">[</span>YOUR-ID<span class="o">]</span>
+NEW passwd: <span class="o">[</span>YOUR-PASSWORD<span class="o">]</span>
+RE-type new passwd: <span class="o">[</span>YOUR-PASSWORD-AGAIN<span class="o">]</span>
+</code></pre></div>
+<p>Or you can use your own apache <code>.htpasswd</code> files in other location for setting up property: <code>auth_basic_user_file</code></p>
+
+<p>Restart NGINX server.</p>
+<div class="highlight"><pre><code class="bash language-bash" data-lang="bash"><span class="nv">$ </span>service nginx restart
+</code></pre></div>
+<p>Then check HTTP Basic Authentication works in browser. If you can see regular basic auth popup and then able to login with credential you entered into <code>.htpasswd</code> you are good to go.</p></li>
+<li><p>More security consideration</p></li>
+</ol>
+
+<ul>
+<li>Using HTTPS connection with Basic Authentication is highly recommended since basic auth without encryption may expose your important credential information over the network.</li>
+<li>Using <a href="./shiro_authentication.html">Shiro Security feature built-into Zeppelin</a> is recommended if you prefer all-in-one solution for authentication but NGINX may provides ad-hoc solution for re-use authentication served by your system&#39;s NGINX server or in case of you need to separate authentication from zeppelin server.</li>
+<li>It is recommended to isolate direct connection to Zeppelin server from public internet or external services to secure your zeppelin instance from unexpected attack or problems caused by public zone.</li>
+</ul>
+
+<h2>Another option</h2>
+
+<p>Another option is to have an authentication server that can verify user credentials in an LDAP server.
+If an incoming request to the Zeppelin server does not have a cookie with user information encrypted with the authentication server public key, the user
+is redirected to the authentication server. Once the user is verified, the authentication server redirects the browser to a specific URL in the Zeppelin server which sets the authentication cookie in the browser.
+The end result is that all requests to the Zeppelin web server have the authentication cookie which contains user and groups information.</p>
