Installing the AEN server#

The AEN server is the administrative front end to the system. This is where users log in to the system, where user accounts are stored, and where admins can manage the system.

Server is installed in the /opt/wakari/wakari-server directory.

Be sure you have the bzip2 package installed. If this package is not installed on your system, install it:

sudo yum install bzip2

Starting Wakari daemons...
installation finished.

After successfully completing the installation script, the installer creates the administrator account—AEN_SRVC_ACCT user—and assigns it a password.


Created password '<RANDOM_PASSWORD>' for user 'aen_admin'

TIP: Record this password. It will be needed in the following steps. It is also available in the installation log file /tmp/wakari_server.log.

Starting NGINX and Elasticsearch#

When SELinux is enabled, it blocks NGINX from connecting to the socket created by Gunicorn. If you have SELinux enabled, run these commands to correct these permissions and allow connections between NGINX and Gunicorn:

sudo semanage fcontext -a -t httpd_var_run_t "/opt/wakari/wakari-server/var/run/wakari-server.sock"
sudo restorecon -r /opt/wakari/wakari-server/var/run

To start NGINX and Elasticsearch to read the new config file:

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
