前言:本人机器:AMD64x2 4400++ 1G 内存

第一阶段-编译安装:
1,从postgresql官网下载postgresql-9.1.3.tar.bz2这个我想大家都知道的
2,把源代码复制到/usr/src/postgresql-9.1.3.tar.bz2 且 cd /usr/src
3,解压: tar xjvf postgresql-9.1.3.tar.bz2
4,进入源码目录: cd postgresql-9.1.3
5,建立pgsql安装目录。这里我选择 :mkdir /usr/pgsql-9.1.3
6,安装必须的工具执行:aptitude install build-essential zlib1g-dev libpam0g-dev libssl-dev libperl-dev kernel-package libncurses5-dev flex bison gawk chkconfig系统会自动安装所以来的软件
7,在源码目录里面执行下面命令:
./configure CFLAGS='-DliNUX_OOM_ADJ=0 -O2 -pipe -march=athlon64 -fomit-frame-pointer -fstack-protector' --prefix=/usr/pgsql-9.1.3 --with-perl --with-openssl --with-pam --enable-nls --disable-deBUG
8,开始编译 :make -j 4
9,变成成功后,执行 make install 安装
10,建立postgresql数据库专用普通权限用户 :adduser psqlroot
11,切换到安装目录: cd /usr/pgsql-9.1.3建立初始化数据库集群文件夹:mkdir date
12,改变date所有权限 chown psqlroot:psqlroot date
13,执行数据库初始化(必须使用psqlroot用户):su - psqlroot -c './initdb /usr/pgsql-9.1.3/date'
14,好了,进入date目录可以看到初始化后的文件,比如conf配置文件等等。

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.

## EDIT FROM HERE

# Installation PREFIX
PREFIX=/usr/pgsql-9.1.3

# Data directory
PGDATA=$PREFIX/date

# Who to run the postmaster as,usually "postgres". (NOT "root")
PGUSER=psqlroot

# 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

## Stop EDITING HERE

# The path that is to be used for the script
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# What to use to start up the postmaster. (If you want the script to wait
# until the server has started,you Could use "pg_ctl start -w" here.
# But without -w,pg_ctl adds no value.)
DAEMON="$PREFIX/bin/postmaster"

# What to use to shut down the postmaster
PGCTL="$PREFIX/bin/pg_ctl"

set -e

# Only start if we can find the postmaster.
test -x $DAEMON ||
{
echo "$DAEMON not found"
if [ "$1" = "stop" ]
then exit 0
else exit 5
fi
}


# Parse command line parameters.
case $1 in
start)
echo -n "Starting Postgresql: "
test x"$OOM_ADJ" != x && echo "$OOM_ADJ" > /proc/self/oom_adj
su - $PGUSER -c "$DAEMON -D $PGDATA &" >>$PGLOG 2>&1
echo "ok"
;;
stop)
echo -n "StopPing Postgresql: "
su - $PGUSER -c "$PGCTL stop -D '$PGDATA' -s -m fast"
echo "ok"
;;
restart)
echo -n "Restarting Postgresql: "
su - $PGUSER -c "$PGCTL stop -D '$PGDATA' -s -m fast -w"
test x"$OOM_ADJ" != x && echo "$OOM_ADJ" > /proc/self/oom_adj
su - $PGUSER -c "$DAEMON -D '$PGDATA' &" >>$PGLOG 2>&1
echo "ok"
;;
reload)
echo -n "Reload Postgresql: "
su - $PGUSER -c "$PGCTL reload -D '$PGDATA' -s"
echo "ok"
;;
status)
su - $PGUSER -c "$PGCTL status -D '$PGDATA'"
;;
*)
# 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'
