sudo service mongod start
sudo chkconfig --add elasticsearch
Setting variables and changing permissions¶
Run:
export AEN_SERVER=<FQDN HOSTNAME OR IP ADDRESS> # Use the real FQDN
chmod a+x aen-*.sh # Set installer to be executable

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