下载源码
解压缩
然后安装库
apt-get install auto-apt automake autoconf
apt-get install libreadline-dev
build-essential 也要
（另外一个教程：aptitude install build-essential zlib1g-dev libpam0g-dev libssl-dev libperl-dev kernel-package libncurses5-dev flex bison gawk chkconfig）
搞不清推荐都装好
设置环境变量
vi /etc/profile
export LD_LIBRARY_PATH=/usr/local/pgsql/lib:$LD_LIBRARY_PATH
export PATH=/usr/local/pgsql/bin:$PATH
export PGDATA=/usr/local/pgsql/data
export MANPATH=$MANPATH:/usr/local/pgsql/man
CD到源码根目录
先执行 ./configure
如果报错的话，优已经装好必要软件，则可以试试忽略错误的方式
./configure --without-readline --without-zlib
然后 make
最好 make install
/usr/local/pgsql 这个是默认的安装目录
建立postgresql数据库专用普通权限用户 :adduser psqlroot
建立数据库文件夹 如： home/data
mkdir /home/data
权限 ： chown psqlroot:psqlroot date
切花数据库用户 su psqlroot
cd 到 pgslq的安装目录 bin文件夹下 执行 以下命令
root@www18130ui:/# cd /usr/local
root@www18130ui:/usr/local# cd pgsql
root@www18130ui:/usr/local/pgsql# cd bin
root@www18130ui:/usr/local/pgsql/bin# su psqlroot
psqlroot@www18130ui:/usr/local/pgsql/bin$ ./initdb -D /home/data
初始化数据库 ./initdb -D /home/data （只能用 psqroot）
到数据库目录 修改 pg_hba.conf 里面加入要登录的IP
修改postgresql.conf中的listen_address=* 及端口 去掉注释#
启动服务。。。测试下
postgres -D /usr/local/pgsql/data
or
pg_ctl -D /usr/local/pgsql/data -l logfile start
远程就可以正常登录了
第二阶段-制作启动脚本：
1，从源代码目录里面复制出原始的开机脚本:
cp /usr/src/postgresql-9.1.3/contrib/start-scripts/linux /etc/init.d/postgresql
2,给予执行权限:chmod 700 /etc/init.d/postgresql
3，建立s 2 3 4 5 6各个级别启动连接在(/etc/rcS.d rc1.d rc2.d rc3.d rc4.d rc5.d rc6.d)
使用:chkconfig /etc/init.d/postgresql自动建立 呵呵很方便哦！
4，修改/etc/init.d/postgresql文件，这个文件是用/bin/sh基础的，改成/bin/bash的：
#! /bin/bash
# chkconfig: 2345 98 02
# description: PostgreSQL RDBMS
# This is an example of a start/stop script for SysV-style init, such
# as is used on Linux systems. You should edit some of the variables
# and maybe the 'echo' commands.
#
# Place this file at /etc/init.d/postgresql (or
# /etc/rc.d/init.d/postgresql) and make symlinks to
# /etc/rc.d/rc0.d/K02postgresql
# /etc/rc.d/rc1.d/K02postgresql
# /etc/rc.d/rc2.d/K02postgresql
# /etc/rc.d/rc3.d/S98postgresql
# /etc/rc.d/rc4.d/S98postgresql
# /etc/rc.d/rc5.d/S98postgresql
# Or, if you have chkconfig, simply:
# chkconfig --add postgresql
#
# Proper init scripts on Linux systems normally require setting lock
# and pid files under /var/run as well as reacting to network
# settings, so you should treat this with care.

# Where to keep a log file
PGLOG=/var/log/serverlog
# It's often a good idea to protect the postmaster from being killed by the
# OOM killer (which will tend to preferentially kill the postmaster because
# of the way it accounts for shared memory). Setting the OOM_ADJ value to
# -17 will disable OOM kill altogether. If you enable this, you probably want
# to compile PostgreSQL with "-DLINUX_OOM_ADJ=0", so that individual backends
# can still be killed by the OOM killer.
OOM_ADJ=-17

# But without -w, pg_ctl adds no value.)

# What to use to shut down the postmaster

;;

# Print help
echo "Usage: $0 {start|stop|restart|reload|status}" 1>&2
exit 1

esac
exit 0
5，注意上文提到的OOM_ADJ=-17 是为了逃避OOM自动封杀，OK！执行/etc/init.d/postgresql start stop restart 等等命令试试，大工告成！！
6,把安装目录中的conf配置文件复制到/etc/postgresql下面去，方便以后更改配置
mkdir /etc/postgresql
mv /usr/pgsql-9.1.3/date/*conf /etc/postgresql/
cd /usr/pgsql-9.1.3/date
su - psqlroot -c 'ln -s /etc/postgresql/pg_hba.conf pg_hba.conf'
su - psqlroot -c 'ln -s /etc/postgresql/pg_ident.conf pg_ident.conf'
su - psqlroot -c 'ln -s /etc/postgresql/postgresql.conf postgresql.conf'
