Illegal option supplied to couchbase-server command tries to start the server and lands user in erlang shell

[nonroot@node1-mad-hatter-testing-centos7 bin]$ ./couchbase-server --s

./couchbase-server: illegal option -- -

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.

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.
