AWSでGlusterを動かしてみます。EBSだと高くつくので、Instance Storeで。まずは、Amazon Linux(ami-5a6cd35b)にInstance Store Volumesを2つくっつけて起動します。
●なにはともあれ、yumアップデート。
[ec2-user@ip-10-156-59-42 ~]$ sudo yum update
[ec2-user@ip-10-156-59-42 ~]$ wget

●Glusterのコンパイルに必要なパッケージをインストール。
[ec2-user@ip-10-156-59-42 ~]$ sudo yum install make gcc flex bison
openssl-static readline-static
●Glusterをコンパイルしてインストール
[ec2-user@ip-10-156-59-42 ~]$ tar zxvf glusterfs-3.3.1.tar.gz
[ec2-user@ip-10-156-59-42 ~]$ cd glusterfs-3.3.1
[ec2-user@ip-10-156-59-42 glusterfs-3.3.1]$ ./configure
(略)
GlusterFS configure summary
===========================
FUSE client : yes
Infiniband verbs : no
epoll IO multiplex : yes
argp-standalone : no

Linux-AIO : no
[ec2-user@ip-10-156-59-42 glusterfs-3.3.1]$ make
(略)
[ec2-user@ip-10-156-59-42 glusterfs-3.3.1]$ sudo make install
(略)
●起動スクリプトをコピーして、使えるか確認。
[ec2-user@ip-10-156-59-42 glusterfs-3.3.1]$ sudo cp
extras/init.d/glusterd-Redhat /etc/init.d/glusterd
[ec2-user@ip-10-156-59-42 glusterfs-3.3.1]$ sudo chmod a+x
/etc/init.d/glusterd
[ec2-user@ip-10-156-59-42 glusterfs-3.3.1]$ sudo /sbin/service glusterd
start
Starting glusterd: [ OK ]
[ec2-user@ip-10-156-59-42 glusterfs-3.3.1]$ sudo /sbin/service glusterd
restart
Stopping glusterd: [ OK ]
Starting glusterd: [ OK ]
[ec2-user@ip-10-156-59-42 glusterfs-3.3.1]$ sudo /sbin/service glusterd stop
Stopping glusterd: [ OK ]
●ここまでで一旦、AMIを作る
※scpなどでX.509証明書と秘密鍵を転送する必要あり。
[ec2-user@ip-10-156-59-42 ~]$ sudo su -
[root@ip-10-156-59-42 ~]# ec2-bundle-vol -d /media/ephemeral0 --privatekey
~ec2-user/PrivateKey.pem --cert ~ec2-user/X509Certificate.pem --user
XXXX-XXXX-XXXX --fstab /etc/fstab
Please specify a value for arch [x86_64]:
(略)
[root@ip-10-156-59-42 ~]# ec2-upload-bundle -r ap-northeast-1 --bucket
My_Bucket/Gluster_Node_Base --manifest /media/ephemeral0/image.manifest.xml
--access-key XXXXXXXXXXXXXXXXXXXX --secret-key
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
(略)
[root@ip-10-156-59-42 ~]# ec2-register --region ap-northeast-1
--aws-access-key XXXXXXXXXXXXXXXXXXXX --aws-secret-key
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX --name gluster_node_base
My_Bucket/Gluster_Node_Base/image.manifest.xml
IMAGE ami-xxxxxxxx
●作成したAMIからインスタンスを作って3台起動。
1台目(ap-northeast-1a)
ec2-46-51-226-247.ap-northeast-1.compute.amazonaws.com
2台目(ap-northeast-1b)
ec2-176-32-64-146.ap-northeast-1.compute.amazonaws.com
3台目(ap-northeast-1c)
ec2-54-248-159-67.ap-northeast-1.compute.amazonaws.com
1台目と2台目のglusterのuuidを変えておく。
[ec2-user@ip-10-152-251-141 ~]$ cd /var/lib/glusterd/
[ec2-user@ip-10-152-251-141 glusterd]$ sudo cp -p glusterd.info
glusterd.info.back
[ec2-user@ip-10-152-251-141 glusterd]$ sudo vi glusterd.info
UUID=48a21eef-7789-45db-8f59-c5214297fbd2
[ec2-user@ip-10-152-251-141 ~]$ sudo /sbin/service glusterd restart
Stopping glusterd: [ OK ]
Starting glusterd: [ OK ]
この時点での各インスタンスのGlusterのUuidは、
1: UUID=48a21eef-7789-45db-8f59-c5214297fbd1
2: UUID=48a21eef-7789-45db-8f59-c5214297fbd2
3: UUID=48a21eef-7789-45db-8f59-c5214297fbd3
にしておいた。
●Glusterにノードを追加(Trusted Storage Poolを作る)
[ec2-user@ip-10-158-173-174 ~]$ sudo /usr/local/sbin/gluster
gluster> peer probe ec2-176-32-64-146.ap-northeast-1.compute.amazonaws.com
Probe successful
State: Peer in Cluster (Connected)
gluster> peer probe ec2-54-248-159-67.ap-northeast-1.compute.amazonaws.com
Probe successful
gluster> peer status
Number of Peers: 2
Hostname: ec2-176-32-64-146.ap-northeast-1.compute.amazonaws.com
Uuid: 48a21eef-7789-45db-8f59-c5214297fbd2
State: Peer in Cluster (Connected)
Hostname: ec2-54-248-159-67.ap-northeast-1.compute.amazonaws.com
Uuid: 48a21eef-7789-45db-8f59-c5214297fbd3
State: Peer in Cluster (Connected)
1台目のノードは、他のノードから追加してあげる。
[ec2-user@ip-10-152-251-141 ~]$ sudo /usr/local/sbin/gluster
gluster> peer probe ec2-46-51-226-247.ap-northeast-1.compute.amazonaws.com
Probe successful
●3つのレプリカを持つクラスタボリュームを作成して起動する。
gluster> volume create test-volume replica 3 transport tcp
ec2-46-51-226-247.ap-northeast-1.compute.amazonaws.com:/media/ephemeral0
ec2-176-32-64-146.ap-northeast-1.compute.amazonaws.com:/media/ephemeral0
ec2-54-248-159-67.ap-northeast-1.compute.amazonaws.com:/media/ephemeral0
Creation of volume test-volume has been successful. Please start the volume
to access data.
gluster> volume start test-volume
Starting volume test-volume has been successful
●マウントしてみる
[ec2-user@ip-10-158-173-174 ~]$ sudo mkdir /media/gluster0
[ec2-user@ip-10-158-173-174 ~]$ sudo mount -t glusterfs
ec2-46-51-226-247.ap-northeast-1.compute.amazonaws.com:/test-volume
/media/gluster0
[ec2-user@ip-10-158-173-174 ~]$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/xvda1 10321208 1349420 8447500 14% /
tmpfs 848480 0 848480 0% /dev/shm
/dev/xvdb 153899044 192084 145889336 1% /media/ephemeral0
ec2-46-51-226-247.ap-northeast-1.compute.amazonaws.com:/test-volume
153899008 192128 145889280 1% /media/gluster0
●テスト
[ec2-user@ip-10-158-173-174 ~]$ sudo cp -rp ./* /media/gluster0/
[ec2-user@ip-10-152-251-141 ~]$ sudo du -a /media/ephemeral0 | wc -l
2346
これで、東京にあるAWSの3つのリージョンをまたぐ分散ファイルシステムの完成。容量は140GB。ひとまず。
