First, installation
centos6.4 Server ip:192.168.220.131
WINDOW7 Client ip:192.168.199.218
Install PostgreSQL via the following instructions on the CentOS website http://www.postgresql.org/download/linux/redhat/
yum install postgresql-server
service postgresql initdb
chkconfig postgresql on
It seems to have been installed, the version is 8.4 because you see the update Word. No matter.
Second, local database user and DB, test the connection
su postgres // Switch to the postgres user created by default
psql // Enter the postgresql command console
CREATE USER root WITH PASSWORD ‘root’;
CREATE DATABASE rootdb WITH OWNER = root TEMPLATE = template0 ENCODING = ‘UNICODE’;
\ q // Exit the postgresql command console
exit // Exit the postgres user to the root user
/ usr / bin / psql -Uroot rootdb // Test local environment user login
Third, Windows7 Client connection test
1) Turn off Firewall service iptables stop
2) after modifying/var/lib/pgsql/data/postgresql.conf (Modify content listen_addresses = ' * '), prompt error
Fatal:no pg_hba.conf entry for Host "192.168.220.1", User "root", database "Rootdb", SSL off
2.1) Restart command service iptables restart
2.2) may be prompted to fail, view log
2.2.1) determine the log file location by viewing the postgresql.conf file
# This is used when logging to stderr:
logging_collector = on # Enable capturing of stderr and csvlog
# into log files. Required to be on for
# csvlogs.
# (change requires restart)
# These are only used if logging_collector is on:
log_directory = ‘pg_log‘ # directory where log files are written, # can be absolute or relative to PGDATA
log_filename = ‘postgresql-%a.log‘ # log file name pattern, # can include strftime() escapes
2.2.2) View log (Tail-f/var/lib/pgsql/data/pg_log/postgresql-sat.log)
LOG: database system was shut down at 2014-09-06 10:09:32 CST
LOG: database system is ready to accept connections
LOG: autovacuum launcher started
3) Modify the/var/lib/pgsql/data/pg_hba.conf as follows
# TYPE DATABASE USER CIDR-ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all ident
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all 192.168.0.0/32 md5
host all all 0.0.0.0/0 md5
# IPv6 local connections:
host all all ::1/128 ident
Finally added the host all 0.0.0.0/0 MD5 so that a successful connection.
