Failed initial Redis installation
The initial Redis installation failed, and re-running the installation scripts produces new errors that were not part of the original installation attempt. This happens because the Redis installer does not perform cleanup after a failed installation. As a result, leftover files or configurations can cause the installer to think it is performing an upgrade or encounter unexpected issues.
To clean up a failed Redis installation:
-
Remove all Redis packages:
sudo yum remove redis*sudo yum remove redis* -
Verify that all Redis packages have been removed:
sudo rpm -qa | grep -i redissudo rpm -qa | grep -i redis -
Once the cleanup is completed, re-run the installation scripts.
Re-running the install scripts might produce new errors, not seen on the original install, such as:-
Traceback (most recent call last): File "rlec_upgrade_tmpdir/upgrade_checks.py", line 6, in <module> import CCS ImportError: No module named CCSTraceback (most recent call last): File "rlec_upgrade_tmpdir/upgrade_checks.py", line 6, in <module> import CCS ImportError: No module named CCSTo address this issue, ensure the required dependencies (like Python modules) are installed before attempting the Redis setup:
pip install CCSpip install CCS -
