PostgreSQLインスト

UbuntuにPostgreSQL9.1をインストールしてみた。

#apt-get install postgresql

インストールする際にユーザー(postgres)も作成されたようなので、パスワードを設定する

#passwd postgres

データ保存場所を作成

#mkdir /home/postgres/datum
#chown postgres:postgres /home/postgres/datum

データベース初期化

$su - postgres
postgres@hoge:/usr/lib/postgresql/9.1/bin$ ./initdb -D /home/postgres/datum/
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 ja_JP.UTF-8.
The default database encoding has accordingly been set to UTF8.
initdb: could not find suitable text search configuration for locale ja_JP.UTF-8
The default text search configuration will be set to "simple".

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

Success. You can now start the database server using:

    ./postgres -D /home/postgres/datum
    or
        ./pg_ctl -D /home/postgres/datum -l logfile start
