[nonroot] SUSE 15 Couchbase server fails to start: mkdir: cannot create directory '/opt/couchbase': Permission denied

ec2-user@ip-172-31-19-37:~/opt/couchbase> ./bin/couchbase-server \-- -noinput -detached

The maximum number of open files for the couchbase user is set too low (1024).

It must be at least 70000.

Normally this can be increased by adding the following lines to

/etc/security/limits.conf:

couchbase              soft    nofile                  <value>

couchbase              hard    nofile                  <value>

Where <value> is greater than 70000. The procedure may be totally

different if you're running so called "non-root/non-sudo install" or

if you've built Couchbase Server from source.
