Debian6.04 Postgresql-9.1.3 安装教材

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'
