postgresql源码安装

Pg安装
1、创建用户, 这个用户随意,不一定非要叫postgres。
Useradd pumpkin ;
2、下载pg源码安装包，目前我用的是9.3.5。
3、源码安装pg
[pumpkin@hl231 ~]$ ll
总用量 21436
-rw-r--r--. 1 pumpkin pumpkin 21946446 7月  25 2014 postgresql-9.3.5.tar.gz
[pumpkin@hl231 ~]$ tar zxf postgresql-9.3.5.tar.gz  -- 解压到当前目录
[pumpkin@hl231 ~]$ mkdir /home/pumpkin/pg9.3 -- 创建安装目录
[pumpkin@hl231 ~]$ ls  -- 当前的目录结构
pg9.3  postgresql-9.3.5  postgresql-9.3.5.tar.gz
[pumpkin@hl231 ~]$ cd postgresql-9.3.5  -- 切换进入解压目录
[pumpkin@hl231 postgresql-9.3.5]$ ./configure --prefix=/home/pumpkin/pg9.3/ --with-openssl  -- 开始初始化并安装

….. 以下都省略了 太多了.
[pumpkin@hl231 postgresql-9.3.5]$ make
…..
[pumpkin@hl231 postgresql-9.3.5]$ make install
…
make[1]: Leaving directory `/home/pumpkin/postgresql-9.3.5/config'
PostgreSQL installation complete. – 看到这些说明已经安装成功了



4、配置一下环境变量
[pumpkin@hl231 ~]$ vim ~/.bash_profile


PATH=$PATH:$HOME/bin
PG_HOME=/home/pumpkin/pg9.3
export PG_HOME

PG_DATA=/home/pumpkin/pgdata
export PG_DATA
PG_PORT=5434
export PG_PORT

PATH=$PG_HOME/bin:$PATH
export PATH

[pumpkin@hl231 ~]$ source ~/.bash_profile  -- 生效

5、初始化pgdata
[pumpkin@hl231 ~]$ mkdir ~/pgdata – 创建目录
[pumpkin@hl231 ~]$ initdb -D ~/pgdata/ --encoding=UTF8 --locale=C  -- 初始化一个数据库实例
The files belonging to this database system will be owned by user "pumpkin".
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:

    postgres -D /home/pumpkin/pgdata/
or
    pg_ctl -D /home/pumpkin/pgdata/ -l logfile start
-初始化完成



初始化完毕之后修改几个参数：
Postgresql.conf 中 修改
listen_addresses = '*'          # what IP address(es) to listen on;
                                        # comma-separated list of addresses;
                                        # defaults to 'localhost'; use '*' for all
                                        # (change requires restart)
port = 5434                             # (change requires restart)
pg_hba.conf 中按照自己的要求进行修改,本次只是用来进行演示，所以我就不改了。
6、启动数据库
[pumpkin@hl231 ~]$ pg_ctl start -D ~/pgdata/  -- 启动数据库
server starting
$[pumpkin@hl231 ~]$ psql -U postgres
psql (9.3.5)
Type "help" for help.

postgres=# select version();
                                                   version
