Re: After configuring remote access,server can't be started

tail  /var/lib/pgsql/9.4/pgstartup.log,got

< 2015-11-22 11:47:42.691 CST >LOG:  could not create IPv6 socket: Address family not supported by protocol
< 2015-11-22 11:47:42.718 CST >LOG:  redirecting log output to logging collector process
< 2015-11-22 11:47:42.718 CST >HINT:  Future log output will appear in directory "pg_log".

Questions are:

  1, Is this "could not create IPv6..." just a warning or the actual reason of starting failure?

thats typically just a warning. 

  2, Where is the pg_log directory?

 

By default, the logs past that above are in $PGDATA/pg_log, which on your system should /var/libpgsql/9.4/data/pg_log   ... look for the newest file after a failed start, and look at the last set of logs.
