网上出现的比较多安装方法要么是源码安装，要么是yum安装，我发觉都要配置很多属性，比较麻烦，所以现在我在centos7长用 run文件来安装
http://get.enterprisedb.com/postgresql/postgresql-9.5.1-1-linux-x64.run
这里的安装shell整理的很零乱，后面会整理一个完整版本的出来
wget https://pgbouncer.github.io/downloads/files/1.7.2/pgbouncer-1.7.2.tar.gz wget http://get.enterprisedb.com/postgresql/postgresql-9.5.1-1-linux-x64.run wget https://github.com/libevent/libevent/releases/download/release-2.0.22-stable/libevent-2.0.22-stable.tar.gz tar zxvf libevent-2.0.22-stable.tar.gz cd libevent-2.0.22-stable ./configure --prefix=/usr/local/libevent make make install cd .. tar zxvf pgbouncer-1.7.2.tar.gz cd pgbouncer-1.7.2 ./configure --prefix=/usr/local/pgbouncer/ --with-libevent=/usr/local/libevent/ make make install cd .. chmod 777 postgresql-9.5.1-1-linux-x64.run ./postgresql-9.5.1-1-linux-x64.run sudo chown -R postgres.postgres /alidata/pgsql sudo chown -R postgres.postgres /usr/local/pgbouncer
#以下为配置环境变量部分，这里还没写好，你可以参考 su - postgres cp .bash_profile /alidata/pgsql cp .bashrc /alidata/pgsql su - postgres export PGHOME=/alidata/pgsql export PATH=$PGHOME/bin:$PATH export PGDATA=$PGHOME/data export LD_LIBRARY_PATH=$PGHOME/lib export LD_LIBRARY_PATH=/usr/local/libevent/lib:$LD_LIBRARY_PATH
用run文件安装就比较简单，但是安装完成后，它会默认安装成linux的系统服务，所以这里需要从源码里面去拷贝
PostgreSQL的开机自启动脚本位于PostgreSQL源码目录的contrib/start-scripts路径下
linux文件即为linux系统上的启动脚本
#chmod a+x linux
#cp linux /etc/init.d/postgresql
#修改/etc/init.d/postgresql文件的两个变量
prefix设置为postgresql的安装路径：/alidata/pgsql
附此文件，如果你没下载源码，可以直接通过在
vi postgresql新建一个文件
把下面这段拷贝进去保存
拷贝进去放到 /etc/init.d/下
然后service postgresql status 可以查询对应的操作
#! /bin/sh
# 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.

# 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). To do that, uncomment these
# three lines:
#PG_OOM_ADJUST_FILE=/proc/self/oom_score_adj
#PG_MASTER_OOM_SCORE_ADJ=-1000
#PG_CHILD_OOM_SCORE_ADJ=0
# Older Linux kernels may not have /proc/self/oom_score_adj, but instead
# /proc/self/oom_adj, which works similarly except for having a different
# range of scores. For such a system, uncomment these three lines instead:
#PG_OOM_ADJUST_FILE=/proc/self/oom_adj
#PG_MASTER_OOM_SCORE_ADJ=-17
#PG_CHILD_OOM_SCORE_ADJ=0

chkconfig --add 服务名称 (首先，添加为系统服务,注意add前面有两个横杠)
chkconfig --leve 启动级别 服务名 on
说明，3级别代表在命令行模式启动，5级别代表在图形界面启动，on表示开启）
chkconfig --leve 启动级别 服务名 off
（说明，off表示关闭自启动）
例如：chkconfig --level 3 postgresql on (说明：让postgresql 服务在命令行模式，随系统启动)
