First Time Starting Up PostgreSQL and Having Problems

I've done a lot of Google searching and PostgreSQL archive searching and can't seem to figure out why I'm having
problems.

     This is a first time install of PostgreSQL version 11.3 on a CentOS server running release 7.6.1810.  I've just
finishedsetting up the postgresql.conf and pg_hba.conf files and am trying to start up PostgreSQL for the first time.
I'mgetting errors no matter what I try.  My first attempt resulted in errors that look like the following: 

        syntax error in file "/var/lib/pgsql/11/data/pg_hba.conf" line 84, near token "all"

I received this error for every configuration line that wasn't a comment.  The "all" is in the USER column.  No matter
whatI put in the USER column, I get the same error, but listing whatever string is in that column.  I wandered if this
errorwas just a result of a different error someplace else, so I commented out all lines in this file.  That resulted
inthe following error: 

        FATAL:  exceeded maxAllocatedDescs (16) while trying to open file "/var/lib/pgsql/11/data/pg_hba.conf"

     I'm at a loss and don't know where to look next.  Any help or pointers would be greatly appreciated.  Thanks.
