Run preflight checks
These pre-installation checks are designed to ensure that your server meets the requirements to run Dash Enterprise smoothly. Once they have passed, click Continue.
Some check failures or warnings do not impede installation or use of Dash Enterprise (see next subsection). If any checks apart from those result in errors or warnings, consult Plotly support before proceeding.
Errors similar to
dial tcp 10.0.20.51:9879: getsockopt: no route to hostoccasionally occur on Centos/RHEL systems and are typically a result of firewall restrictions on your server. To determine whether the firewall is the issue:
- Open a terminal and run
sudo systemctl stop firewalld
- Reload the preflight checks page
If the above resolves the issue, disable firewalld (if possible) to continue. If disabling firewalld is not an option, add docker0 to the list of active zones, using the below commands as an example:
firewall-cmd --zone=trusted --add-interface=docker0
