ubuntu下用apt-get方式安装postgresql 9.3
参考了http://forum.digitser.cn/thread-244-1-1.html的文章，感谢原作者！
记录一下：
1、更新一下软件源：
sudo apt-get update2、直接用命令安装额外的软件包：
sudo apt-get install postgresql-9.3 postgresql-client-9.3 postgresql-client-common postgresql-common
sudo apt-get install postgresql
会提示将会安装下列额外的软件包：postgresql-9.3 postgresql-client-9.3 postgresql-client-common postgresql-common
3、设置 Ubuntu Server 14.04 系统 postgres 用户登陆口令
root:# passwd postgres
输入新的 UNIX 密码：
重新输入新的 UNIX 密码：
passwd: password updated successfully
root:#4、切换到 postgres 系统用户
root:# su - postgres 或 sudo -i -u postgres
postgres:~$5、登录 postgres 数据库
postgres:~$ psql postgres
psql (9.3.5)
Type "help" for help.
postgres=# #postgres 命令提示符6、将 postgres 数据库用户口令设为 postgres 或其它
postgres=# ALTER USER postgres with PASSWORD 'postgres';
ALTER ROLE
postgres=# \q
could not save history to file "/var/lib/postgresql/.psql_history": 没有那个文件或目录 #重新登录就可以了，由于第一次文件是不存在的
postgres:~$7、再次登陆 postgres 数据库，再将 postgres 数据库用户口令设为 postgres 或其它
postgres:~$ psql postgres
psql (9.3.5)
Type "help" for help.
postgres=# ALTER USER postgres with PASSWORD 'postgres';
ALTER ROLE
postgres=# \q
postgres:~$8、修改 PostgresSQL 数据库配置文件 postgresql.conf
gedit /etc/postgresql/9.3/main/postgresql.conf或
vi /etc/postgresql/9.3/main/postgresql.conf9、
修改前的配置文件
# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
# name = value
#
# (The "=" is optional.) Whitespace may be used. Comments are introduced with
# "#" anywhere on a line. The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal. If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload". Some
# parameters, which are marked below, require a server shutdown and restart to
# take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on". Some parameters can be changed at run time
# with the "SET" SQL command.

# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# Refer to the "Client Authentication" section in the PostgreSQL
# documentation for a complete description of this file. A short
# synopsis follows.
#
# This file controls: which hosts are allowed to connect, how clients
# are authenticated, which PostgreSQL user names they can use, which
# databases they can access. Records take one of these forms:
#
# local DATABASE USER METHOD [OPTIONS]
# host DATABASE USER ADDRESS METHOD [OPTIONS]
# hostssl DATABASE USER ADDRESS METHOD [OPTIONS]
# hostnossl DATABASE USER ADDRESS METHOD [OPTIONS]
#
# (The uppercase items must be replaced by actual values.)
#
# The first field is the connection type: "local" is a Unix-domain
# socket, "host" is either a plain or SSL-encrypted TCP/IP socket,
# "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a
# plain TCP/IP socket.
#
# DATABASE can be "all", "sameuser", "samerole", "replication", a
# database name, or a comma-separated list thereof. The "all"
# keyword does not match "replication". Access to replication
# must be enabled in a separate record (see example below).
#
# USER can be "all", a user name, a group name prefixed with "+", or a
# comma-separated list thereof. In both the DATABASE and USER fields
# you can also write a file name prefixed with "@" to include names
# from a separate file.
#
# ADDRESS specifies the set of hosts the record matches. It can be a
# host name, or it is made up of an IP address and a CIDR mask that is
# an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that
# specifies the number of significant bits in the mask. A host name
# that starts with a dot (.) matches a suffix of the actual host name.
# Alternatively, you can write an IP address and netmask in separate
# columns to specify the set of hosts. Instead of a CIDR-address, you
# can write "samehost" to match any of the server's own IP addresses,
# or "samenet" to match any address in any subnet that the server is
# directly connected to.
#
# METHOD can be "trust", "reject", "md5", "password", "gss", "sspi",
# "krb5", "ident", "peer", "pam", "ldap", "radius" or "cert". Note that
# "password" sends passwords in clear text; "md5" is preferred since
# it sends encrypted passwords.
#
# OPTIONS are a set of options for the authentication in the format
# NAME=VALUE. The available options depend on the different
# authentication methods -- refer to the "Client Authentication"
# section in the documentation for a list of which options are
# available for which authentication methods.
#
# Database and user names containing spaces, commas, quotes and other
# special characters must be quoted. Quoting one of the keywords
# "all", "sameuser", "samerole" or "replication" makes the name lose
# its special character, and just match a database or username with
# that name.
#
# This file is read on server startup and when the postmaster receives
# a SIGHUP signal. If you edit the file on a running system, you have
# to SIGHUP the postmaster for the changes to take effect. You can
# use "pg_ctl reload" to do that.
# Put your actual configuration here
# ----------------------------------
#
# If you want to allow non-local connections, you need to add more
# "host" records. In that case you will also need to make PostgreSQL
# listen on a non-local interface via the listen_addresses
# configuration parameter, or via the -i or -h command line switches.
# DO NOT DISABLE!
# If you change this first entry you will need to make sure that the
# database superuser can access the database using some other method.
# Noninteractive access to all databases is required during automatic
# maintenance (custom daily cronjobs, replication, and similar tasks).
#
# Database administrative login by Unix domain socket
local all postgres peer
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all peer
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
#host replication postgres 127.0.0.1/32 md5
#host replication postgres ::1/128 md5
# to allow your client visiting postgresql server
host all all 0.0.0.0 0.0.0.0 md5
最后一行 host 表示允许类型是主机；第一个 all 是允许访问数据库名称；第二个 all 是允许用户；第一个 0.0.0.0 是允许访问 IP Address；第二个 0.0.0.0 是允许访问 SubNet Mask；最后 md5 表示密码加密方式，如果将 md5 改成 trust，在指定范围的主机访问数据库时无需提供密码。
IP Address 和 SubNet Mask 项也可修改为您的机器 IP 地址 (譬如：10.13.19.53)和子网掩码 (譬如：255.255.255.255)，这样就只有您自己的主机才可远程访问数据库。要使用一个 IP 地址范围，只需要把 SubNet Mask 设置成合适的值。
若把 SubNet Mask 设成 0.0.0.0，则所有主机均可访问数据库 (IP Address 可任意设定)。若将 md5 改成 trust，可让指定范围的主机访问指定数据库时无需提供密码。
10、重启 PostgresSQL 9.3.5
root:# /etc/init.d/postgresql restart
* Restarting PostgreSQL 9.3 database server [ OK ]
root:#11、登陆测试 PostgresSQL 9.3.5

12、
安装并配置数据库
进入postgres用户shell（postgres是数据库默认的管理员，由安装程序创建，如果未装 sudo apt-get install postgresql ）：
a)
sudo su - postgres
为OE创建数据库用户，按照提示输入用户密码。：
b)以下命令即用username为postgres的账户创建一个no-createrole no-superuser --pwprompt权限的odoo账户输入的密码请牢记了后面要写在odoo的conf配置文件里：
createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo
（要删除以前自动安装残留的postgresql 里面的 openerp用户 用dropuser openerp）
退出postgres用户shell：
c)
exit
13、最后加odoo8.0的deb安装源来安装odoo8.0：
wget -O - https://nightly.odoo.com/odoo.key | apt-key add -
echo "deb http://nightly.odoo.com/8.0/nightly/deb/ ./" >> /etc/apt/sources.list
apt-get update && apt-get install odoo完毕！
