アップグレード ・DBバックアップ ・/var/lib/pgsql（例）をリネームか削除 ・DBインストール 必用ならば古いパッケージなどを削除・DBリストア ・参考 CentOS7にインストール ・インストール # yum -y install postgresql13-server・バージョン確認 ・データベース初期化 (V13、照合順序とCtype(変換演算子)は「C」) # /usr/pgsql-13/bin/postgresql-13-setup initdb Initializing database ... OK /var/lib/pgsql/13/initdb.log
データベースシステム内のファイルの所有者はユーザ"postgres"となります。
このユーザをサーバプロセスの所有者とする必要があります。
データベースクラスタはロケール"ja_JP.UTF-8"で初期化されます。
デフォルトのデータベース符号化方式はそれに対応してUTF8に設定されました。
initdb: ロケール"ja_JP.UTF-8"用の適切なテキスト検索設定が見つかりませんでした
デフォルトのテキスト検索構成は simple に設定されます。
データベージのチェックサムは無効です。
ディレクトリ/var/lib/pgsql/13/dataの権限を設定しています ... ok
サブディレクトリを作成しています ... ok
動的共有メモリの実装を選択しています ... posix
デフォルトのmax_connectionsを選択しています ... 100
デフォルトのshared_buffersを選択しています ... 128MB
デフォルトの時間帯を選択しています ... Asia/Tokyo
設定ファイルを作成しています ... ok
ブートストラップスクリプトを実行しています ... ok
ブートストラップ後の初期化を実行しています ... ok
データをディスクに同期しています ... ok
成功しました。以下のようにしてデータベースサーバを起動することができます:
/usr/pgsql-13/bin/pg_ctl -D /var/lib/pgsql/13/data/ -l xxxxxx.log start
・データベース初期化やり直し var/lib/pgsql/（あれば）/data配下を削除・インストール済パッケージ # rpm -qa | grep postgres PL/PerlやPL/TCLなど、各種言語IFが必要な場合、それぞれに対応するPKGを入れる。・インストール済ファイルとディレクトリ /var/lib/pgsql/13/→設定、データ、バックアップファイルが保存されるディレクトリ /var/lib/pgsql/13/data/postgresql.conf→メインとなる設定ファイル /var/lib/pgsql/13/data/pg_hba.conf→ユーザ認証用設定ファイル 「/var/lib/pgsql/13」以下は、initdbを実行したときに作成される。 DBクラスタ作成時には「13」を削除する。 /usr/pgsql-13/bin/createdb→データベース作成用コマンド /usr/pgsql-13/bin/psql→操作用クライアント /usr/pgsql-13/bin/postgres→DBサーバー・ユーザ（Linux）確認 # su - postgres $ id uid=26(postgres) gid=26(postgres) groups=26(postgres) ・・・・・データベースサーバを起動 /usr/pgsql-13/bin/pg_ctl -D /var/lib/pgsql/13/data -l testxxxx.log start 「testxxxx.log」は、カレントディレクトリにできる。・環境設定 （/var/lib/pgsql/.bash_profile） PATH=/usr/pgsql-13/bin:$PATH MANPATH=/usr/pgsql-13/share/man:$MANPATH デフォルトで検索される場所にインストールした場合を除く。 PGDATA=/var/lib/pgsql/13/data export PATH MANPATH PGDATA 再読み込み（/var/lib/pgsql/.bash_profile） 参考 ・サーバー起動などのサービス化など サービス化 postgresql.conf
