linux下安装postgresql

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

Postgresql版本：postgresql.9.5.3

添加开启自启设置：http://my.oschina.net/ensn/blog/690719

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。

[root@localhost postgresql-9.5.3]# less INSTALL
                  PostgreSQL Installation from Source Code

   This document describes the installation of PostgreSQL using the source
   code distribution. (If you are installing a pre-packaged distribution,
   such as an RPM or Debian package, ignore this document and read the
   packager's instructions instead.)

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 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

[root@localhost ~]# su - postgres
[postgres@localhost ~]$ echo $PGDATA
/usr/local/pgsql9.5.3/data
[postgres@localhost ~]$ pwd
[postgres@localhost ~]$ /usr/local/pgsql9.5.3/bin/initdb -E UTF8 -D $PGDATA  --locale=C -U postgres -W
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "C".
The default text search configuration will be set to "english".

Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

    /usr/local/pgsql9.5.3/bin/pg_ctl -D /usr/local/pgsql9.5.3/data -l logfile start

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

　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.
