Wazuh Offline Installation fails due to trying to install wazuh-templates.json with no internet connection #3072

Closed CarlosALgit closed 3 months ago

CarlosALgit commented 3 months ago
Wazuh version Install type Action performed Platform
4.9.0-beta2 Indexer Offline Install Amazon Linux 2023

While performing the Installation Assistant for 4.9.0-beta2 test I followed the steps for the Offline Installation on the documentation and the installation freezed on this message:

14/08/2024 08:51:43 INFO: Wazuh indexer cluster security configuration initialized.

This occurs after running the command for starting the cluster:

bash wazuh-install.sh --start-cluster

After investigating with my team, we discovered that the error comes from this line in the indexer.sh file. This tries to download the wazuh-template.json file using curl in the host you are supposed to not need internet. https://github.com/wazuh/wazuh-packages/blob/add6b475bc45a66cf76b90176678669c1bce731d/unattended_installer/install_functions/indexer.sh#L190

So, the fix needed is to change this curl command to the part of the installation process where you have internet connection.

Update report

The error mentioned by David is due to the issue of file parsing. I have been analyzing and found problems in this case PUT'. In principle the error occurs when the command is passed through the common_curl where the single quote is removed:
