建立好database cluster目标文件夹

[root@fnddb postgresql-9.4.0]# mkdir /var/lib/pgsql/data -p
[root@fnddb postgresql-9.4.0]# chown -R postgres /var/lib/pgsql

环境变量设置

[postgres@fnddb ~]$ vi .bash_profile 
…
# postgres
PGDATA=/var/lib/pgsql/data
PATH=/usr/local/pgsql/bin:$PATH
export PGDATA PATH

[postgres@fnddb ~]$ . .bash_profile 

创建database cluster

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 "en_US.UTF-8".
The default database encoding has accordingly been set to "UTF8".
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/pgsql/bin/postgres -D /var/lib/pgsql/data
or
    /usr/local/pgsql/bin/pg_ctl -D /var/lib/pgsql/data -l logfile start

启动数据库实例

设置好PGDATA环境变量后,可以不带-D选项

[postgres@fnddb ~]$ pg_ctl start -l /var/lib/pgsql/pgsql.log

关闭数据库实例

[postgres@fnddb ~]$ pg_ctl stop
