Installing Archivematica on CentOS/Red Hat¶

Installation instructions¶

1. Prerequisites

   Update your system

   sudo yum -y update
   

   If your environment uses SELinux, at a minimum you will need to run the following commands. Additional configuration may be required for your local setup.

   # Allow Nginx to use ports 81 and 8001
   sudo semanage port -m -t http_port_t -p tcp 81
   sudo semanage port -a -t http_port_t -p tcp 8001
   # Allow Nginx to connect the MySQL server and Gunicorn backends
   sudo setsebool -P httpd_can_network_connect_db=1
   sudo setsebool -P httpd_can_network_connect=1
   # Allow Nginx to change system limits
   sudo setsebool -P httpd_setrlimit 1
   

2. Some extra repositories need to be installed in order to fulfill the installation procedure.

   • Extra packages for enterprise Linux:

   sudo yum install -y epel-release
   

   • Elasticsearch (optional):

   Note

   Skip this step if you are planning to run Archivematica without Elasticsearch.

   sudo -u root rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
   sudo -u root bash -c 'cat << EOF > /etc/yum.repos.d/elasticsearch.repo
   [elasticsearch-6.x]
   name=Elasticsearch repository for 6.x packages
   baseurl=https://artifacts.elastic.co/packages/6.x/yum
   gpgcheck=1
   gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
   enabled=1
   autorefresh=1
   type=rpm-md
   EOF'
   

   • Archivematica - use these commands to install the repositories:

   sudo -u root bash -c 'cat << EOF > /etc/yum.repos.d/archivematica.repo
   [archivematica]
   name=archivematica
   baseurl=https://packages.archivematica.org/1.10.x/centos
   gpgcheck=1
   gpgkey=https://packages.archivematica.org/1.10.x/key.asc
   enabled=1
   EOF'
   
   sudo -u root bash -c 'cat << EOF > /etc/yum.repos.d/archivematica-extras.repo
   [archivematica-extras]
   name=archivematica-extras
   baseurl=https://packages.archivematica.org/1.10.x/centos-extras
   gpgcheck=1
   gpgkey=https://packages.archivematica.org/1.10.x/key.asc
   enabled=1
   EOF'
   

3. Common services like Elasticsearch, MariaDB and Gearmand should be installed and enabled before the Archivematica install.

   Note

   Do not enable Elasticsearch if you are running Archivematica in indexless mode.

   sudo -u root yum install -y java-1.8.0-openjdk-headless elasticsearch mariadb-server gearmand
   sudo -u root systemctl enable elasticsearch
   sudo -u root systemctl start elasticsearch
   sudo -u root systemctl enable mariadb
   sudo -u root systemctl start mariadb
   sudo -u root systemctl enable gearmand
   sudo -u root systemctl start gearmand
   

4. Install Archivematica Storage Service

   • First, install the packages:

     sudo -u root yum install -y python-pip archivematica-storage-service
     

   • After the package is installed, populate the SQLite database, and collect some static files used by django. These tasks must be run as “archivematica” user.

     sudo -u archivematica bash -c " \
     set -a -e -x
     source /etc/sysconfig/archivematica-storage-service
     cd /usr/lib/archivematica/storage-service
     /usr/share/archivematica/virtualenvs/archivematica-storage-service/bin/python manage.py migrate";
     

   • Now enable and start the archivematica-storage-service, rngd (needed for encrypted spaces) and the Nginx frontend:

     sudo -u root systemctl enable archivematica-storage-service
     sudo -u root systemctl start archivematica-storage-service
     sudo -u root systemctl enable nginx
     sudo -u root systemctl start nginx
     sudo -u root systemctl enable rngd
     sudo -u root systemctl start rngd
     

     Note

     The Storage Service will be available at http://<ip>:8001.

5. Installing Archivematica Dashboard and MCP Server

   There are a number of environment variables that Archivematica recognizes which can be used to alter how it is configured. For the full list, see the Dashboard install README, the MCPClient install README, and the MCPServer install README.

   • First, install the packages:

     sudo -u root yum install -y archivematica-common archivematica-mcp-server archivematica-dashboard
     

   • Create user and mysql database with:

     sudo -H -u root mysql -hlocalhost -uroot -e "DROP DATABASE IF EXISTS MCP; CREATE DATABASE MCP CHARACTER SET utf8 COLLATE utf8_unicode_ci;"
     sudo -H -u root mysql -hlocalhost -uroot -e "CREATE USER 'archivematica'@'localhost' IDENTIFIED BY 'demo';"
     sudo -H -u root mysql -hlocalhost -uroot -e "GRANT ALL ON MCP.* TO 'archivematica'@'localhost';"
     

   • And as archivematica user, run migrations:

     sudo -u archivematica bash -c " \
     set -a -e -x
     source /etc/sysconfig/archivematica-dashboard
     cd /usr/share/archivematica/dashboard
     /usr/share/archivematica/virtualenvs/archivematica-dashboard/bin/python manage.py migrate
     ";
     

   • Start and enable services:

     sudo -u root systemctl enable archivematica-mcp-server
     sudo -u root systemctl start archivematica-mcp-server
     sudo -u root systemctl enable archivematica-dashboard
     sudo -u root systemctl start archivematica-dashboard
     

   • Restart Nginx in order to load the dashboard config file:

     sudo -u root systemctl restart nginx
     

     Note

     The dashboard will be available at http://<ip>:81

6. Installing Archivematica MCP client

   • Install the package:

     sudo -u root yum install -y archivematica-mcp-client
     

   • The MCP Client expects some programs in certain paths, so we put them in place:

     sudo ln -sf /usr/bin/7za /usr/bin/7z
     

   • Tweak ClamAV configuration:

     sudo -u root sed -i 's/^#TCPSocket/TCPSocket/g' /etc/clamd.d/scan.conf
     sudo -u root sed -i 's/^Example//g' /etc/clamd.d/scan.conf
     

   • Indexless mode:

     If you are planning on running Archivematica in indexless mode (i.e., without Elasticsearch), then modify the relevant systemd EnvironmentFile files by adding lines that set the relevant environment variables to false:

     sudo sh -c 'echo "ARCHIVEMATICA_DASHBOARD_DASHBOARD_SEARCH_ENABLED=false" >> /etc/sysconfig/archivematica-dashboard'
     sudo sh -c 'echo "ARCHIVEMATICA_MCPSERVER_MCPSERVER_SEARCH_ENABLED=false" >> /etc/sysconfig/archivematica-mcp-server'
     sudo sh -c 'echo "ARCHIVEMATICA_MCPCLIENT_MCPCLIENT_SEARCH_ENABLED=false" >> /etc/sysconfig/archivematica-mcp-client'
     

   • After that, we can enable and start/restart services

     sudo -u root systemctl enable archivematica-mcp-client
     sudo -u root systemctl start archivematica-mcp-client
     sudo -u root systemctl enable fits-nailgun
     sudo -u root systemctl start fits-nailgun
     sudo -u root systemctl enable clamd@scan
     sudo -u root systemctl start clamd@scan
     sudo -u root systemctl restart archivematica-dashboard
     sudo -u root systemctl restart archivematica-mcp-server
     

7. Finalizing installation

   Configuration

   Each service has a configuration file in /etc/sysconfig/archivematica-packagename

   Troubleshooting

   If IPv6 is disabled, Nginx may refuse to start. If that is the case make sure that the listen directives used under /etc/nginx are not using IPv6 addresses like [::]:80.

   CentOS will install firewalld which will be running default rules that will likely be blocking ports 81 and 8001. If you are not able to access the dashboard and Storage Service, then use the following command to check if firewalld is running:

   sudo systemctl status firewalld
   

   If firewalld is running, you will likely need to modify the firewall rules to allow access to ports 81 and 8001 from your location:

   sudo firewall-cmd --add-port=81/tcp --permanent
   sudo firewall-cmd --add-port=8001/tcp --permanent
   sudo firewall-cmd --reload
   

8. Complete Post Install Configuration.

Post-install configuration¶

After successfully completing a new installation, follow these steps to complete the configuration of your new server.

1. The Storage Service runs as a separate web application from the Archivematica dashboard. The Storage Service is exposed on port 8001 by default when deploying using RPM packages. Use your web browser to navigate to the Storage Service at the IP address of the machine you have been installing on, e.g., http://<MY-IP-ADDR>:8001 (or http://localhost:8001 or http://127.0.0.1:8001 if this is a local development setup).

   If you are using an IP address or fully-qualified domain name instead of localhost, you will need to configure your firewall rules and allow access only to ports 81 and 8001 for Archivematica usage.

2. The Storage Service has its own set of users. Create a new user with full admin privileges:

   sudo -u archivematica bash -c " \
       set -a -e -x
       source /etc/default/archivematica-storage-service || \
           source /etc/sysconfig/archivematica-storage-service \
               || (echo 'Environment file not found'; exit 1)
       cd /usr/lib/archivematica/storage-service
       /usr/share/archivematica/virtualenvs/archivematica-storage-service/bin/python manage.py createsuperuser
     ";
   

   After you have created this user, the API key will be generated automatically, and that key will connect the Archivematica pipeline to the Storage Service API. The API key can be found via the web interface (go to Administration > Users).

3. To finish the installation, use your web browser to navigate to the Archivematica dashboard using the IP address of the machine on which you have been installing, e.g., http://<MY-IP-ADDR>:81 (or http://localhost:81 or http://127.0.0.1:81 if this is a local development setup).

4. At the Welcome page, create an administrative user for the Archivematica pipeline by entering the organization name, the organization identifier, username, email, and password.

5. On the next screen, connect your pipeline to the Storage Service by entering the Storage Service URL and username, and by pasting in the API key that you copied in Step (2).

   • If the Storage Service and the Archivematica dashboard are installed on the same machine, then you should supply http://127.0.0.1:8001 as the Storage Service URL at this screen.
   • If the Storage Service and the Archivematica dashboard are installed on different nodes (servers), then you should use the IP address or fully-qualified domain name of your Storage Service instance, e.g., http://<MY-IP-ADDR>:8001 and you must ensure that any firewall rules (i.e., iptables, ufw, AWS security groups, etc.) are configured to allow requests from your dashboard IP to your Storage Service IP on the appropriate port.
