2007/6/XX release 1.1
-
-* fix ocf script to work properly with pgpool 3.2+ .
-* Works well with pgpool-II.
-* New configuration variables added .
- you can specify path of configuration files . It means you can run multiple pgpool instances on single heartbeat instance.

pgpoolconf path to pgpool.conf
pcpconf path to pcp.conf
hbaconf path to pool_hba/.conf

1. What's this?
2.0+ required.
- pgpool
- Tested on 3.0+ only , but It will work if 'show pool_status' command was supported.
- pgpool.conf on default path is only supported.
+ Tested on pgpool-II only , but It will work if 'show pool_status' command
+ was supported.
- PostgreSQL 7.0+
'psql' also needed for install hosts . postmaster doesn't required.

この設定ファイル例によりpgpoolを管理できるようになります。この中で書き換える項目は以下の通りになります。
-ノード名
-設定ファイルの格納場所(任意)
設定ファイルの格納場所がデフォルト以外の場合、instance_attributes項目に以下のキーと、値としてそのファイル名を指定することで設定できます。
-ファイル名 , 指定するキー , 備考
-pgpool.conf , pgpoolconf ,
-pool_hba.conf , hbaconf , pgpool 3.2以降で有効
-pcp.conf , pcpconf , pgpool-IIでのみ有効
-
- なお、この設定はpgpool 1.1以降でのみ有効です。
-
--ログファイルの出力先
- 設定ファイルの格納場所と同様、ログファイルの出力先を指定することも可能です。logfileをキーに、対応するファイル名を
-値として記述することで指定場所にリダイレクト出力するようになります。なお、ログファイル出力時は-d、デバッグオプションが
-自動的に付与されます。
-
-
-
-
- 以下に、実際の設定例を示します。ここでは、先の設定ファイルのpgpool設定部分
-のみを記述しますので、随時置き換えてください。
-
- <primitive class="ocf" id="pgpool_2" provider="heartbeat"
-type="pgpool">
- <operations>
- <op id="pgpool_2_mon" interval="30s" name="monitor"
-timeout="20s"/>
- </operations>
- <instance_attributes id="4e369437-b6ac-4f47-96bd-029f7e4a95fc">
- <attributes>
- <nvpair id="pgpool_2_attr_1" name="pgpoolconf"
- value="/path/to/pgpool.conf"/>
- <nvpair id="pgpool_2_attr_2" name="hbaconf"
- value="/path/to/pool_hba.conf"/>
- <nvpair id="pgpool_2_attr_3" name="pcpconf"
- value="/path/to/pcp.conf"/>
- <nvpair id="pgpool_2_attr_4" name="logfile"
- value="/path/to/logfile"/>
- </attributes>
- </instance_attributes>
- </primitive>
+ファイル名 , 指定するキー , 備考
+pgpool.conf , pgpoolconf ,
+pool_hba.conf , hbaconf , pgpool 3.2+ only
+pcp.conf , pcpconf , pgpool-II only
+log file , logfile , pgpoolからリダイレクト出力するログファイル
+pid file , pidfile , logdir='/tmp' なら /tmp/pgpool.pid を指定
+ログファイル出力時はデバッグオプション -d が自動的に付与されます。
この記述が終了したらファイルをheartbeatが利用する全てのサーバーに配置します。cib.xmlはサーバー間で全く同じである必要があります。なお、記述の検証にはheartbeatに付属しているcrm_verifyコマンドが使えます。
-crm_verify -VX /opt/powergres/hb/var/lib/heartbeat/crm/cib.xml
+crm_verify -VX /var/lib/heartbeat/crm/cib.xml
最後に全てが終わったら起動して確認します。
pgpool-HA
1.1以降では、複数の設定ファイルが記述できるため、Active-Active構成を取ることが可能になります。
