[nonroot] couchbase-server fails to start with error: ./bin/couchbase-server: line 110: erl: command not found

[ec2-user@ip-172-31-25-154 couchbase]$ ./bin/couchbase-server \-- -noinput -detached

The maximum number of processes for the couchbase user is set too low (4096).

It must be at least 10000.

Normally this can be increased by adding the following lines to

/etc/security/limits.conf:

couchbase              soft    nproc                  <value>

couchbase              hard    nproc                  <value>

Where <value> is greater than 10000. 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.
