During the REST API installation, do not set the noexec option that restricts running programs in the /tmp and /var/tmp directories.
You can check whether the noexec option is set by running the mount command.
After the REST API installation finishes, setting the option to restrict running programs in those directories will not affect REST API operations.
-
You must log in to the management server as the root user.
-
The COLUMNS environment variable must not be set.
If you perform an upgrade or overwrite installation while the COLUMNS environment variable is set, the installation might not end normally.
- Stop any programs that are using the CCI that was provided
with the REST API.
If CCI files are used in an environment where the CCI provided with the REST API is installed, you cannot perform an upgrade or overwrite installation of the REST API.
