OS X Mountaion Lion で MacPorts を使って開発環境を整える(postgres編)
まずは、
$ sudo port install postgresql90
とすると終わり際に、
To use the postgresql server, install the postgresql90-server port
と出るので、引き続き、
$ sudo port install postgresql90-server
を実行。終わり際に、
########################################################### # A startup item has been generated that will aid in # starting postgresql90-server with launchd. It is disabled # by default. Execute the following command to start it, # and to cause it to launch at startup: # # sudo port load postgresql90-server ###########################################################
と、
To create a database instance, after install do sudo mkdir -p /opt/local/var/db/postgresql90/defaultdb sudo chown postgres:postgres /opt/local/var/db/postgresql90/defaultdb sudo su postgres -c '/opt/local/lib/postgresql90/bin/initdb -D /opt/local/var/db/postgresql90/defaultdb' To tweak your DBMS, consider increasing kern.sysv.shmmax by adding an increased kern.sysv.shmmax .. to /etc/sysctl.conf
が出る。
順番にやっていく。
$ sudo port load postgresql90-server $ sudo mkdir -p /opt/local/var/db/postgresql90/defaultdb $ sudo chown postgres:postgres /opt/local/var/db/postgresql90/defaultdb $ sudo su postgres -c '/opt/local/lib/postgresql90/bin/initdb -D /opt/local/var/db/postgresql90/defaultdb'
ここで、だーっと出る。
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:
/opt/local/lib/postgresql90/bin/postgres -D /opt/local/var/db/postgresql90/defaultdb
or
/opt/local/lib/postgresql90/bin/pg_ctl -D /opt/local/var/db/postgresql90/defaultdb -l logfile start
最後のやつをやってみる。
$ /opt/local/lib/postgresql90/bin/postgres -D /opt/local/var/db/postgresql90/defaultdb
エラーになる。
postgres cannot access the server configuration file "/opt/local/var/db/postgresql90/defaultdb/postgresql.conf": Permission denied
パーミッションの問題か。
sudo su postgres して再トライ。
$ sudo su postgres $ /opt/local/lib/postgresql90/bin/postgres -D /opt/local/var/db/postgresql90/defaultdb LOG: database system was shut down at 2012-08-11 04:10:00 JST LOG: autovacuum launcher started LOG: database system is ready to accept connections
動いたっぽい。
$ /opt/local/lib/postgresql90/bin/psql -l -U postgres List of databases
Name | Owner | Encoding | Collation | Ctype | Access privileges
-----------+----------+----------+-----------+-------+-----------------------
postgres | postgres | UTF8 | C | C |
template0 | postgres | UTF8 | C | C | =c/postgres +
| | | | | postgres=CTc/postgres
template1 | postgres | UTF8 | C | C | =c/postgres +
| | | | | postgres=CTc/postgres
(3 rows)
よさそうだ。
パスを通しておく。
$ vim .profile
export PATH=/opt/local/lib/postgresql90/bin:$PATH
テスト用DBを作っておく。
$ createdb sample_db -U postgres -E UTF-8
psqlして、
$ psql sample_db -U postgres
テーブルを作る。
sample_db=# CREATE TABLE users ( sample_db(# id SERIAL PRIMARY KEY, sample_db(# name varchar(255) sample_db(# ); NOTICE: CREATE TABLE will create implicit sequence "users_id_seq" for serial column "users.id" NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "users_pkey" for table "users" CREATE TABLE
確認。
sample_db=# \d
List of relations
Schema | Name | Type | Owner
--------+--------------+----------+----------
public | users | table | postgres
public | users_id_seq | sequence | postgres
(2 rows)
sample_db=# \d users
Table "public.users"
Column | Type | Modifiers
--------+------------------------+----------------------------------------------------
id | integer | not null default nextval('users_id_seq'::regclass)
name | character varying(255) |
Indexes:
"users_pkey" PRIMARY KEY, btree (id)
データを入れておく。
sample_db=# INSERT INTO users (name) VALUES ('yamada');
INSERT 0 1
セレクトして確認。
sample_db=# select * from users; id | name ----+-------- 1 | yamada (1 row)
再びportでインストール
$ sudo port install php5-postgresql
アパッチ再起動
$ sudo /opt/local/apache2/bin/apachectl restart
infophp()で確認。
簡単なphpを書いて接続テスト。
<?php
$conn = pg_pconnect("dbname=sample_db user=postgres");
if (!$conn) {
echo "An error occured.\n";
exit;
}
$result = pg_query($conn, "SELECT * FROM users");
if (!$result) {
echo "An error occured.\n";
exit;
}
while ($row = pg_fetch_row($result)) {
echo "Id: $row[0] Name: $row[1]";
echo "<br />\n";
}
表示される。
Id: 1 Name: yamada
よさそうだ。
