お仕事でLinux環境でHAクラスタを検証する必要が出てきたので、手順を調べてみました。
|
||
|
|
|
||
|
|
## 環境
|
||
|
|
RHEL 6.4環境で検証しております:
|
||
|
|
|
||
|
|
```
|
||
|
|
# cat /etc/redhat-release
|
||
|
|
Red Hat Enterprise Linux Server release 6.4 (Santiago)
|
||
|
|
```
|
||
|
|
|
||
|
|
当然ながらCentOS6でも動作するかと思います。RHEL 7 or CentOS7ではOSの仕組みが変わっていると思いますので、ここでまとめた手順の通りにしてもおそらく動作しません。
|
||
|
|
|
||
|
|
ホスト名一覧などは以下のとおりです:
|
||
|
|
|
||
|
|
| # | Hostname | IP Address | Remarks |
|
||
|
|
|:-:|:--------:|:----------:|:-------:|
|
||
|
|
| 1 | rhel-act | 192.168.56.31 | Active server |
|
||
|
|
| 2 | rhel-sta | 192.168.56.32 | Standby server |
|
||
|
|
| 3 | rhel-logical | 192.168.56.30 | Logical hostname / floating IP |
|
||
|
|
| 4 | rhel-iscsi | 192.168.56.40 | iScsi server |
|
||
|
|
|
||
|
|

## Pacemaker + Corosyncのインストール
|
||
|
|
Pacemaker + Corosyncのインストール方法を説明します。
|
||
|
|
|
||
|
|
### インストール方法
|
||
|
|
以下のコマンドを実行し、インストールします。なお、`rhel-act`およびに`rhel-sta`サーバ上で実施します:
|
||
|
|
|
||
|
|
```
|
||
|
|
# yum install -y pacemaker cman pcs
|
||
|
|
```
|
||
|
|
|
||
|
|
### セットアップ方法
|
||
|
|
セットアップ方法を説明します。
|
||
|
|
|
||
|
|
#### Quorumの無効化
|
||
|
|
以下のコマンドを実行し、Quorumを無効化します。なお、`rhel-act`およびに`rhel-sta`サーバ上で実施します:
|
||
|
|
|
||
|
|
```
|
||
|
|
# cd /etc/sysconfig/
|
||
|
|
# cp -p cman cman.${YYYYMMDD}
|
||
|
|
# vi cman
|
||
|
|
# diff -u cman.${YYYYMMDD} cman

|
||
|

|
|
#### `hauser`ユーザのパスワード設定
|
||
|
|
クラスタ操作で利用する`hauser`ユーザのパスワードを設定します。`rhel-act`およびに`rhel-sta`サーバで同じパスワードを指定してあげます。ここでは「p@ssword」を指定することとします。
|
||
|
|
|
||
|
|
なお、`rhel-act`およびに`rhel-sta`サーバ上で実施してください。
|
||
|
|
|
||
|
|
```
|
||
|
|
# passwd hacluster
|
||
|
|
Changing password for user hacluster.
|
||
|
|
New password:
|
||
|
|
BAD PASSWORD: it is based on a dictionary word
|
||
|
|
Retype new password:
|
||
|
|
passwd: all authentication tokens updated successfully.
|
||
|
|
```
|
||
|
|
|
||
|
|
#### `pcsd` デーモンの自動起動設定
|
||
|
|
クラスタ関連デーモンの`pcsd`デーモンをOS起動時に自動起動するように設定します。なお、`rhel-act`およびに`rhel-sta`サーバ上で実施してください:
|
||
|
|
|
||
|
|
```
|
||
|
|
# cd
|
||
|
|
# service pcsd status
|
||
|
|
pcsd is stopped
|
||
|
|
# service pcsd start
|
||
|
|
Starting pcsd: [ OK ]
|
||
|
|
# service pcsd status
|
||
|
|
pcsd (pid 1345) is running...
|
||
|
|
# chkconfig --list > 001-before.txt
|
||
|
|
# chkconfig pcsd on
|
||

#### `corosync`の自動起動の抑止
|
||
|
|
クラスタ関連デーモンの`pcsd`デーモンから起動されるようですので、OS起動時に`Corosync`を自動起動しないように設定します。なお、`rhel-act`およびに`rhel-sta`サーバ上で実施してください:
|
||
|
|
|
||
|
|
```
|
||
|
|
# chkconfig corosync off
|
||
|
|
```
|
||
|
|
|
||
|
|
#### クラスタのセットアップ
|
||
|
|
以下のコマンドを実行して、クラスタのセットアップを実行します。なお、`rhel-act` or `rhel-sta`のいずれか一方で実行してください。
|
||
|
|
|
||
|
|
以下のコマンドを実行し、クラスタソフトで利用するOSユーザ・パスワードを指定します:
|
||
|
|
|
||
|
|
```
|
||
|
|
# pcs cluster auth rhel-act rhel-sta -u hacluster -p p@ssw0rd
|
||
|
|
rhel-act: Authorized
|
||
|
|
rhel-sta: Authorized
|
||
|
|
```
|
||
|
|
|
||
|
|
以下のコマンドを実行し、クラスタソフト上でクラスタを構成します:
|
||
|
|
|
||
|
|
```
|
||
|
|
# pcs cluster setup --start --name cluster rhel-act rhel-sta
|
||
|
|

||
|
|
rhel-sta: Success

||
|
|
|
||
|
|
Restarting pcsd on the nodes in order to reload the certificates...
|
||
|
|
rhel-act: Success
|
||
|
|
rhel-sta: Success
|
||
|
|
```
|
||
|
|
|
||
|
|
以下のコマンドを実行し、構成したクラスタを有効化します:
|
||
|
|
|
||
|
|
```
|
||
|
|
# pcs cluster enable --all
|
||
|
|
rhel-act: Cluster Enabled
|
||
|
|
rhel-sta: Cluster Enabled
|
||
|
|
```
|
||
|
|
|
||
|
|
`crm_verify`コマンドを実行し、設定内容を検証します:
|
||
|
|
|
||
|
|
```
|
||
|
|
# crm_verify -L -V
|
||
|
|
error: unpack_resources: Resource start-up disabled since no STONITH resources have been defined
|
||
|
|
error: unpack_resources: Either configure some or disable STONITH with the stonith-enabled option
|
||
|
|
error: unpack_resources: NOTE: Clusters with shared data need STONITH to ensure data integrity
|
||
|
|
Errors found during check: config not valid
|
||
|
|
```
|
||
|
|
|
||
|
|
上の例では、STONITHの設定でエラーが出ています。今回の例ではSTONITHは使用しないため、無効化します。また、Quorumも利用しないため、無効化します。無効化するための設定は以下になります:
|
||
|
|
|
||
|
|
```
|
||
|
|
# pcs property set stonith-enabled=false
|
||
|
|
# pcs property set no-quorum-policy=ignore
|
||
|
|
```
|
||
|
|
|
||
|
|
### クラスタリソースの登録
|
||
|
|
クラスタリソースの登録方法を説明します。
|
||
|
|
|
||
|
|
#### 論理IPアドレスの登録
|
||
|
|
`pcs resource create vip ocf:heartbeat:IPaddr2`を実行し、論理IPアドレスを登録します。ここでは、`192.168.56.30`を登録します。なお、クラスタリソースグループとして`resource-group`を指定しています:
|
||
|
|
|
||
|
|
```
|
||
|
|
# pcs resource create vip ocf:heartbeat:IPaddr2 ¥
|
||
|
|
ip="192.168.59.30" cidr_netmask "24" nic="eth0" ¥
|
||
|
|
op start timeout="20s" on-fail="restart" ¥
|
||
|
|
op stop timeout="20s" on-fail="block" ¥
|
||
|
|
op monitor interval="10s" timeout="20s" on-fail="restart" ¥
|
||
|
|
--group resource-group
|
||
|
|
```
|
||
|
|
|
||
|
|
上記のコマンドを実行後、`pcs status`コマンドを実行し、クラスタリソースが登録されているかを確認します:
|
||
|
|
|
||
|
|
```
|
||
|
|
# pcs status
|
||
|
|
Cluster name: cluster
|
||

|
||
|
|
|
||
|
|
#### 共有ディスクの登録
|
||
|
|
`iSCSI`を利用した共有ディスクリソースを登録します。
|
||
|
|
|
||
|
|
`iSCSI`を利用したクラスタリソース登録用の`Pacemaker`スクリプトがインストールされていなかったため、まずは`rhel-act`およびに`rhel-sta`サーバ上で以下のコマンドを実行し、スクリプトを登録します:
|
||
|
|
|
||
|
|
```
|
||
|
|
# cd /usr/lib/ocf/resource.d/heartbeat/
|
||
|
|
# wget https://raw.githubusercontent.com/ClusterLabs/resource-agents/master/heartbeat/iscsi --no-check-certificate
|
||
|
|
# chmod +x iscsi
|
||
|
|
```
|
||
|
|
|
||
|
|
ダウンロード後、`rhel-act` or `rhel-sta`サーバ上で以下のコマンドを実行します。まずは`pcs resource create shared_device ocf:heartbeat:iscsi`を実行し、`iSCSI`で共有ディスクを参照できるようにします:
|
||
|
|
|
||
|
|
```
|
||
|
|
pcs resource create shared_device ocf:heartbeat:iscsi \
|
||
|
|
params \
|
||
|
|
portal="192.168.59.40:3260" \
|
||
|
|
target="iqn.2016-06.local.test.has:sdb" \
|
||
|
|
op start on-fail=block \
|
||
|
|
op stop on-fail=block \
|
||
|
|
op mointor on-fail=restart \
|
||
|
|
--group resource-group
|
||
|
|
```
|
||
|
|
|
||
|
|
その後、`pcs resource create shared_mount Filesystem`を実行し、`iSCSI`で参照できるようになったデバイスをマウントします:
|
||
|
|
|
||
|
|
```
|
||
|
|
pcs resource create shared_mount Filesystem \
|
||
|
|
device="/dev/sdb1" \
|
||
|
|
directory="/share" \
|
||
|
|
fstype="ext4" \
|
||
|
|
op start on-fail=block \
|
||
|
|
op stop on-fail=block \
|
||
|
|
op mointor on-fail=restart \
|
||
|
|
--group resource-group
|
||
|
|
```
|
||
|
|
|
||
|
|
#### プログラムをクラスタリソースとして登録する
|
||
|
|
お仕事で使うプログラムは、
|
||
|
|
|
||
|
|
- 起動コマンドを指定する
|
||
|
|
- 停止コマンドを指定する
|
||
|
|
- 状態監視コマンドを指定する
|
||
|
|
|
||
|
|
という方法でクラスタソフトに登録することを想定していましたが、クラスタソフト側ではそのような登録をすることができませんでした。しょうがないので、以下のようなクラスタリソース登録用のスクリプトを作成しました。`/usr/lib/ocf/resource.d/heartbeat/anything`という名称で保存してください:
|
||
|
|
|
||
|
|
```

||
|
