centos6.4下面安装postgresql以及客户端远程连接

一、安装

centos6.4服务器IP：192.168.220.131

window7客户端IP：192.168.199.218

在centos官网http://www.postgresql.org/download/linux/redhat/，通过如下指令安装postgresql

yum install postgresql-server
service postgresql initdb
chkconfig postgresql on 

貌似已经安装过了，版本是8.4，因为看到update字样。不管。

二、本地建立数据库用户和DB，测试连接

su postgres //切换到默认建立的postgres用户
psql //进入postgresql命令控制台
CREATE USER root WITH PASSWORD 'root';
CREATE DATABASE rootdb WITH OWNER = root TEMPLATE = template0 ENCODING = 'UNICODE';
\q //退出postgresql命令控制台
exit //退出postgres用户到root用户
/usr/bin/psql -Uroot rootdb //测试本地环境用户登录

三、windows7客户端连接测试

1）关闭防火墙 service iptables stop

2）修改/var/lib/pgsql/data/postgresql.conf（修改内容listen_addresses = '*'）后，提示错误

FATAL: no pg_hba.conf entry for host "192.168.220.1", user "root", database "rootdb", SSL off

　　2.1）重启命令 service iptables restart

　　2.2）可能会提示失败，查看log

　　　　2.2.1）确定log文件位置，通过查看postgresql.conf文件

　　　　

# 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）查看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）修改/var/lib/pgsql/data/pg_hba.conf ，如下

# 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

最后添加了host all all 0.0.0.0/0 md5这么一段，成功连接。
