Tatsuo,
Thanks for your interest. Unfortunately I still get the same result.
Relevant config files are:
pgpool.conf:
ssl = on
ssl_key = './server.key'
ssl_cert = './server.crt'
key and cert made by running (as postgres user):
openssl req -new -text -out server.req (filling out with simple
passphrase, and local hostname as name)
openssl rsa -in privkey.pem -out server.key
rm privkey.pem
openssl req -x509 -in server.req -text -key server.key -out server.crt
chmod og-rwx server.key
server.req and server.crt copied to /etc/pgpool-II and chowned to
postgres:postgres
pool_hba.conf:
host all all 127.0.0.1/32 md5
host all all ::1/128 md5
pool_passwd updated with postgres user and hash
pg_hba.conf on server:
hostssl all all 192.168.10.0/24 md5
I start pgpool, and there are no warnings in log even with debug set to 4.
When I try to connect from localhost (on pgpool machine) I get
psql template1 -h localhost -p9999
psql: could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 9999?
or
psql template1 -h 127.0.0.1 -p9999
psql:
(the console just echoes 'psql' and returns)
pgpool.log shows
2014-05-05 11:49:55 LOG: pid 4474: connection received: host=pgpoolhost
port=36970

2014-05-05 11:49:55 DEBUG: pid 4474: pool_read_string: read all from
pending data. po:1 len:148
Everything works fine when ssl is set to "off" and hostssl is changed to
'host' in pg_hba.conf.
And SSL connections work fine with identical config files when I use
locally-compiled pgpool with ./configure --prefix=/usr --with-openssl
--with-pgsql=/usr/pgsql-9.3
Is there anything else I can do to further debug this?
Thanks,
Rick Morris
