环境:
CentOS6.5 x64
PHP 5.3.3
Apache-2.2.15
postgres (PostgreSQL) 8.4.18
phpPgAdmin-5.1

一.安装postgresql,php,httpd
[root@sentinel ~]# yum -y install postgresql-server postgresql php php-pgsql

二.配置php
[root@sentinel ~]# vim /etc/php.ini
safe_mode_allowed_env_vars = PHP_,PG
safe_mode_exec_dir = /usr/bin

三.配置postgresql
1.启postgresql服务
[root@sentinel ~]# postgres --version
postgres (PostgreSQL) 8.4.18
[root@sentinel ~]# service  postgresql initdb
Initializing database: [  OK  ]
[root@sentinel ~]# service postgresql start
Starting postgresql service: [  OK  ]
[root@sentinel ~]# chkconfig postgresql on
[root@sentinel ~]# chkconfig --list postgresql
postgresql         0:off    1:off    2:on    3:on    4:on    5:on    6:off
[root@sentinel ~]# netstat -tunlp|grep post
tcp        0      0 127.0.0.1:5432              0.0.0.0:*                   LISTEN      1709/postmaster
 
2.配置postgresql
a.主配置文件/var/lib/pgsql/data/postgresql.conf
[root@sentinel ~]# vim /var/lib/pgsql/data/postgresql.conf
listen_addresses = '*'
port = 5432
track_activities = on
track_counts = on
[root@sentinel ~]# service postgresql restart
Stopping postgresql service: [  OK  ]
Starting postgresql service: [  OK  ]
[root@sentinel ~]# netstat -tunlp|grep post
tcp        0     0 0.0.0.0:5432                0.0.0.0:*                   LISTEN      3149/postmaster
b.客户端认证配置文件/var/lib/pgsql/data/pg_hba.conf
http://www.postgres.cn/docs/9.4/auth-pg-hba-conf.html
[root@sentinel ~]# vim /var/lib/pgsql/data/pg_hba.conf
local   all         all                              md5
host    all         all         127.0.0.1/32          md5
