Nginx no-www to www
-------------------
server {
    #listen 80 is default
    server_name www.example.com;
    return 301 $scheme://example.com$request_uri;
}

server {
    #listen 80 is default
    server_name example.com;
    ## here goes the rest of your conf...
}


Redirect both, non-SSL and SSL to their non-www counterpart:
------------------------------------------------------------
server {
    listen 80;
    listen 443 ssl;
    server_name www.example.com;
    return 301 $scheme://example.com$request_uri;
}

server {
    listen 80;
    listen 443 ssl;
    server_name example.com;
    # rest goes here...
}

httpd.conf
