How To: Installing Alfresco 6 on Ubuntu Server

This posting will descibe the installation process of Alfresco 6 on an Ubuntu Server.

The following prequeries are required:

• Working Ubuntu server (18.04.3 LTS) with access to the internet
• SSH or Terminal access to Ubuntu

On another version of Ubuntu the installation process will be similiar.

We will use the following locations:

• Installation path Alfresco 6: /usr/local/alfresco
• Data path where alfresco should store the repository content: /mnt/data/alfresco-data/

1. Install the requirements

Alfresco requires the following software on the destination system:

• Java JDK (we use OpenJDK)
• PostgreSQL Server & Client (for managing the database)
• ImageMagick
• LibreOffice
• FFmpeg

Installing Java JDK

sudo apt-get install openjdk-11-jre

sudo apt-get install openjdk-11-jdk

Installing PostgreSQL

sudo apt-get install postgresql

sudo apt-get install postgresql-client

Set admin password for Postgresql:

Display the data-directory:

sudo -u postgres createuser -P -d alfresco

sudo -u postgres createdb -O alfresco alfresco

Installing ImageMagick

sudo apt-get install imagemagick imagemagick-doc

Installing LibreOffice

sudo apt-get install libreoffice libreoffice-l10n-de libreoffice-help-de

Installing FFmpeg

sudo apt-get install ffmpeg

2. Download and extract Tomcat

• Create an folder where Alfresco and tomcat should be installed, e.g.: /usr/local/alfresco/ (This is also the ‘root’ or ‘base’ folder of the alfresco instance)
• Create an folder where the content of alfresco should be stored, e.g.: /data/alfresco/
• Download an extract tomcat: https://docs.alfresco.com/community/tasks/alf-tomcat-install.html

3. Download and extract the alfresco system

• Download and extract Alfresco system: https://docs.alfresco.com/community/tasks/alf-tomcat-install.html
• Copy the extracted tomcat and alfresco folders to the folder where the application should resist.

4. Configure Alfresco

• Follow this guide to install Alfresco (Step 7 of installing tomcat application server can be skipped beacuse we do not use mutual TLS): https://docs.alfresco.com/community/tasks/alf-tomcat-install.html
• Install Alfrsco search services without mutual TLS: https://docs.alfresco.com/search-community/tasks/solr-install-withoutSSL.html
• Define the location for storing solr content in alfresco-search-services/solrhome/conf/shared.properties:
  #solr content store location
  solr.content.dir=/mnt/data/alfresco-data/alf_data/solr/contentstore
• Start solr:
  ./solr/bin/solr start -a «-Dcreate.alfresco.defaults=alfresco,archive “
• To execute the apply_amps.sh script it is necessary to set the $JAVA_HOME variable:
  export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
• Configure alfresco-global.properties, use this file as template and modify it. Finally copy it to: usr/local/alfresco/tomcat/shared/classes/
• Install/Deploy the amp files using the following command:
  sh ./bin/apply_amps.sh
• Check if you have the appropriate folder structure in the root folder of alfresco:
  |– alf_data
  |– alfresco-pdf-renderer
  |– alfresco-search-services
  |– amps
  |– amps_share
  |– bin
  |– licenses
  |– modules
  |– platform
  |– share
  |– tomcat

5. Test alfresco

• Test if solr is running: http://localhost:8983
• Start Tomcat by executing the following command from the tomcate directory: ./bin/startup.sh
• Open http://localhost:8080 and login (Default: admin/admin)
• Tail with tail -f ./logs/catalina.out the log files of tomcat
• With ps -ef | grep tomcat you can see if an instance of tomcat is running
• With kill PID you can kill tomcat
• Share and alfresco are creating its own log files, called alfresco.log and share.log
• Configure the storage path of the log files of alfresco: https://blyx.com/2014/02/18/alfresco-tip-logs/

6. Put an apache server in front of alfresco

1. Install apache:
   sudo apt-get install apache2
2. After installing Apache2, the commands below can be used to stop, start and enable Apache2 service to automatically start up everytime the server starts:
   sudo systemctl stop apache2.service
   sudo systemctl start apache2.service
   sudo systemctl enable apache2.service
3. Enable Apache2 Proxy Modules:
   sudo a2enmod proxy
   sudo a2enmod proxy_http
4. Restart Apache:
   sudo systemctl restart apache2.service
5. Create a new site configuration in /etc/apache2/sites-available/ with the name alfresco.conf
6. Put the following configuration into the file:

   ServerName alfresco.mydomain.com
   ServerAlias alfresco
   ServerAdmin webmaster@example.com
   ErrorLog $/error.log
   CustomLog $/access.log combinedProxyRequests Off
   
   Order deny,allow
   Allow from all
   

7. Install SSL Certificate and reconfigure apache to use https

1. Install modul ssl:
   sudo a2enmod ssl
2. Restart apache service:
   sudo service apache2 restart
3. Create a csr request and get the crt and the key from your SSL Provider (You can use the csr generator from your SSL provider)
4. Put/Copy the crt and key file to (this is the default storage location for certifcates):
   /etc/ssl/certs/
5. Configure the virtual host to support ssl. Change the content of /etc/apache2/sites-available/alfresco.conf to:
   
   SSLEngine on
   SSLCertificateFile /etc/ssl/certs/alfresco_nettania_net.crt
   SSLCertificateKeyFile /etc/ssl/certs/alfresco.nettania.net.keyServerName alfresco.nettania.net
   ServerAlias alfresco
   ServerAdmin Administrator@mydomain.com
   ErrorLog $/error.log
   CustomLog $/access.log combinedProxyRequests Off
   
   Order deny,allow
   Allow from all
   ProxyPass / http://127.0.0.1:8080/
   ProxyPassReverse / http://127.0.0.1:8080/
   Order allow,deny
   Allow from all
   
   
6. Change the connector in tomcat´s server.xml to the following configuration:
   connectionTimeout=»20000″
   proxyName=»alfresco.mydomain.com»
   proxyPort=»443″
   scheme=»https»
   secure=»true»/>
   With this configuration you can prevent the following problems:
   • Possible CSRF attack noted when asserting referer header
   • The browser informs that some content might be not secure
7. Restart Apache and tomcat and test the configuration
