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'
