Install AEN Server (AEN 4.1.2)#
The AEN Server is the administrative front-end to the Anaconda Enterprise Notebooks. This is where users login to the system, where user accounts are stored, and where admins can manage the system.
These procedures assume you have already met all installation requirements in Installation preparation.
AEN Server preparation prerequisites¶
Install bzip2 package¶
Make sure you have the bzip2 package installed. If not, you can install it with:
sudo yum install bzip2
Download prerequisite RPMs¶
Which Red Hat Package Management (RPM) installer files you will need depends on which version of CentOS or Red Hat you’re using.

Install prerequisite RPMs¶
sudo yum install -y *.rpm
sudo service mongod start
sudo chkconfig --add elasticsearch
Run the AEN Server installer¶
Set variables and change permissions¶
export AEN_SERVER=<FQDN HOSTNAME OR IP ADDRESS> # Use the real FQDN
chmod a+x aen-*.sh # Set installer to be executable
Run AEN Server installer¶
sudo -E ./aen-server-4.1.2-Linux-x86_64.sh -w $AEN_SERVER

installation finished.
As part of the installation script, the installer creates the
administrator account (AEN_SRVC_ACCT user, also known as user wakari)
and assigns it a password. Record this password to use in the following steps.
It is also available in the installation log file found at
/tmp/wakari_server.log. This password can be changed in the
admin interface.
Start NGINX and ElasticSearch¶
When SELinux is enabled, httpd_can_network_connect is disabled by default,
which prevents NGINX from connecting to Gunicorn. If you have SELinux enabled,
run this command to correct these permissions and allow connections between
NGINX and Gunicorn:
sudo setsebool httpd_can_network_connect 1 -P
Start NGINX and ElasticSearch to read the new config files:
sudo service nginx start
sudo service elasticsearch start
TIP: If the AEN web page shows an NGINX 404 error, restart NGINX:
sudo nginx -s stop
sudo nginx
Test the AEN Server install¶
Visit http://$AEN_SERVER. You should be shown the “No license found” page.
Update the license¶
From the “No license found” page, follow the onscreen instructions to upload your license file. After submitting it, you should see the login page.
