RE: Re: Re: Re: Issue with postgres login

Thanks for your response. But now I am giving below error while restore the backup
./pg_restore -i -h localhost -p 5432 -U postgres --role postgres -d fleotan -W -v /backup/fleotanOne11.backup >& /backup/fleotanOne32_restore.log

pg_restore: [archiver (db)] connection to database "fleotan" failed: FATAL: Ident authentication failed for user "postgres"

pga_hba.conf have :

# TYPE DATABASE USER ADDRESS METHOD

# "local" is for Unix domain socket connections only
#local all all peer
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all 0.0.0.0/0 md5
# IPv6 local connections:
host all all ::1/128 ident
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
#host replication postgres 127.0.0.1/32 ident
#host replication postgres ::1/128 ident

Plz suggest

It appears our file permissions are too wide open (which correlated with the error message you shared in your previous email. Changing those to 700 should get you going in the correct direction.

Also we have change the below parameters in Postgres.conf file to resolve the issue but still not resolved.

listen_addresses = '*
port = 5432
max_connections = 100
unix_socket_directories = '/tmp'
unix_socket_group = ''
unix_socket_permissions = 0777

It appears the permissions with your data directory have changed. According to the error message, you should set the appropriate permissions for /var/lib/pgsql/9.3/data

But it was working fine earlier.

Another message I have seen after starting by

It seems you may have just the postgresql package installed and not the postgresql-server package. This Linode guide may be helpful:

Hi team,

We are facing the below issue while logging with postgres as given below:

Password:
Last login: Thu Nov 23 16:15:45 UTC 2017 on pts/1

Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
-bash-4.2$
