1.配置postgreql 可以遠程訪問：
sudo vim /etc/postgresql/9.1/main/postgresql.conf
root@ubuntuserver:~# sudo vi /etc/postgresql/9.1/main/postgresql.conf
—>改變行：#listen_addresses = ‘localhost’
—>修改為：listen_addresses = ‘*’
—>改變行：#password_encryption = on
—>修改為：password_encryption = on
root@ubuntuserver:~# sudo vi /etc/postgresql/9.1/main/pg_hba.conf
—>文件末添加行：# to allow your client visiting postgresql server
—>文件末添加行：host all all 0.0.0.0 0.0.0.0 md5
root@ubuntuserver:~# sudo /etc/init.d/postgresql-9.1 restart
2.修改默認的postgres 密碼
sudo -u postgres psql template1
ALTER USER postgres with encrypted password 'your_password'
3.重啟POSTGRESQL服務
sudo /etc/init.d/postgresql-9.1 restart
