环境：Linux localhost.localdomain 2.6.32-431 GNU/Linux x86_64

Postgresql版本：postgresql.9.5.3

1.下载postgresql

因bz2格式包格式比较小，故选择该格式下载。地址：https://www.postgresql.org/ftp/source/v9.5.3/

2.安装：

2.1 解压：

tar jxvf postgresql-9.5.3.tar.bz2

2.2 安装：

查看INSTALL文件说明安装过程。

2.2.1 编译

在编译过程中可以指定安装目录与wal日记大小等。编译过程过程中如遇其他问题（可能是依赖库的问题），解决以后重新编译即可。关于编译指定参数与编译过程中可能碰到的问题可参考该博文。

3.创建数据库集群

3.1创建用户，用以配置环境变量与初始化数据库等。

[root@localhost pgsql9.5.3]# useradd postgres
[root@localhost pgsql9.5.3]# su - postgres
[postgres@localhost ~]$ 

3.2 创建数据库集群

3.2.1 创建数据目录，并给postgres用户以权限

[root@localhost pgsql9.5.3]# mkdir data
[root@localhost pgsql9.5.3]# ll
总用量 20
drwxr-xr-x. 2 root root 4096 6月  13 11:17 bin
drwxr-xr-x. 2 root root 4096 6月  13 14:38 data
drwxr-xr-x. 6 root root 4096 6月  13 11:17 include
drwxr-xr-x. 4 root root 4096 6月  13 11:17 lib
drwxr-xr-x. 6 root root 4096 6月  13 11:17 share
[root@localhost pgsql9.5.3]# pwd
/usr/local/pgsql9.5.3
[root@localhost pgsql9.5.3]# chown -R postgres:postgres /usr/local/pgsql9.5.3/data

3.2.2 配置环境变量

在postgresql用户下配置环境变量只对postgres用户有效，如要对所有用户有效，配置profile。

[root@localhost ~]# su - postgres
[postgres@localhost ~]$ less ~/.bash_profile
# .bash_profile...export PATH=/usr/local/pgsql9.5.3/bin:$PATH
LD_LIBRARY_PATH=/usr/local/pgsql9.5.3/lib
export LD_LIBRARY_PATH
export PGDATA=/usr/local/pgsql9.5.3/data
....[postgres@localhost ~]$ source ~/.bash_profile
[postgres@localhost ~]$ 

3.2.3 初始化

[root@localhost ~]# su - postgres
[postgres@localhost ~]$ echo $PGDATA
/usr/local/pgsql9.5.3/data
[postgres@localhost ~]$ pwd
/home/postgres
[postgres@localhost ~]$ /usr/local/pgsql9.5.3/bin/initdb -E UTF8 -D $PGDATA  --locale=C -U postgres -W

You can change this by editing pg_hba.conf or using the option -A, or

4. 启动数据库

4.1 配置postgresql.conf 和 pg_hba.conf。

4.2 启动数据库

[root@localhost ~]# su - postgres
[postgres@localhost data]$ pg_ctl start -D $PGDATA
server starting
[postgres@localhost data]$ LOG:  redirecting log output to logging collector process
HINT:  Future log output will appear in directory "pg_log".[postgres@localhost data]$

postgres 11284 11277  0 15:37 ?        00:00:00 postgres: stats collector process 

4.3 登录数据库

[root@localhost pgsql9.5.3]# su - postgres
[postgres@localhost ~]$ psql
psql (9.5.3)
Type "help" for help.postgres=# \d
No relations found.
postgres=# \lList of databasesName    |  Owner   | Encoding | Collate | Ctype |   Access privileges

至此安装完毕。

4.4 设置开启自启

服务正常或者异常产生的重启都需要重启postgres，可通过设置linux启动项设置自启动， PostgreSQL的开机自启动脚本位于PostgreSQL源码目录的contrib/start-scripts路径下 ，

[root@localhost contrib]# ll |grep start-scripts
drwxrwxrwx. 3 1107 1107  4096 5月  10 05:05 start-scripts
[root@localhost contrib]# cd start-scripts
[root@localhost start-scripts]# ll
总用量 12
-rw-r--r--. 1 1107 1107 1529 5月  10 04:50 freebsd
-rw-r--r--. 1 1107 1107 3642 5月  10 04:50 linux
drwxrwxrwx. 2 1107 1107 4096 5月  10 05:05 osx

linux即为开机启动脚本文件，文件包含设置说明：

[root@localhost start-scripts]# less linux
#! /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.# Original author:  Ryan Kirkpatrick <pgsql@rkirkpat.net># contrib/start-scripts/linux
....

4.4.1 修改linux文件属性，添加X属性

[root@localhost start-scripts]# chmod a+x linux 

4.4.2 复制linux文件到/etc/init.d目录下，更名为postgresql

[root@localhost start-scripts]# cp linux  /etc/init.d/postgresql

4.4.3  修改/etc/init.d/postgresql文件的两个变量

prefix设置为postgresql的安装路径，PGDATA设置为postgresql的数据目录路径：

     29 ## EDIT FROM HERE30 31 # Installation prefix32 #prefix=/usr/local/pgsql33 prefix=/usr/local/pgsql9.5.334 35 # Data directory36 PGDATA="/usr/local/pgsql9.5.3/data"

4.4.4 重启数据库服务

[root@localhost init.d]# service postgresql stop
Stopping PostgreSQL: ok
[root@localhost init.d]# service postgresql start
Starting PostgreSQL: ok

4.4.5 添加到启动项

[root@localhost init.d]# chkconfig --add postgresql
[root@localhost init.d]# chkconfig --list|grep postgres
postgresql      0:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭

本文是源码安装过程，该种安装方式可以在安装过程中配置一些参数。其他还有rmp等方式可参考博文1。原安装包中的各文件以及安装过程中的参数说明等可参考博文2。
