用GlusterFS+Swift搭建对象存储

在已经搭建好的GlusterFS服务器上（如不知道如何搭建GlusteFS请参考上一篇）：

Create bricks:

# truncate -s 1GB /srv/disk{1..4}# for i in `seq 1 4`;do mkfs.xfs -i size=512 /srv/disk$i ;done# mkdir -p /export/brick{1..4}

Add the following lines to /etc/fstab to auto-mount the the bricks on system startup:

/srv/disk1    /export/brick1   xfs   loop,inode64,noatime,nodiratime 0 0
/srv/disk2    /export/brick2   xfs   loop,inode64,noatime,nodiratime 0 0
/srv/disk3    /export/brick3   xfs   loop,inode64,noatime,nodiratime 0 0
/srv/disk4    /export/brick4   xfs   loop,inode64,noatime,nodiratime 0 0

Mount the bricks:

# mount -a

You can now create and start the GlusterFS volume. Make sure your hostname is in /etc/hosts or is DNS-resolvable.

# gluster volume create swift-test-vol-01 replica 2 transport tcp cnsz22VLK5966.ossit.sfdc.com.cn:/export/brick{1..4}/data force

Mount the GlusterFS volume:

# mkdir -p /mnt/gluster-object/test-vol-01

# mount -t glusterfs cnsz22VLK5966.ossit.sfdc.com.cn:swift-test-vol-01 /mnt/gluster-object/test-vol-01

Installing Openstack Swift

# yum install centos-release-openstack-newton （ http://mirrors.aliyun.com/centos/7/extras/x86_64/Packages/）

# yum install openstack-swift-* （ http://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-newton/）

Installing gluster-swift （注意安装版本要与openstack swift版本一致）

# yum install epel-release （ http://mirrors.aliyun.com/centos/7/extras/x86_64/Packages/）

# yum install python-scandir （ https://pypi.python.org/packages/77/3f/916f524f50ee65e3f465a280d2851bd63685250fddb3020c212b3977664d/scandir-1.6.tar.gz#md5=0180ddb97c96cbb2d4f25d2ae11c64ac）

#yum install python-prettytable （安装python相关包过程中如果遇到gcc相关编译报错，请执行yum install python-devel 安装python开发包）

#yum install git

# git clone https://github.com/gluster/gluster-swift; cd gluster-swift

# python setup.py install

gluster-swift configuration files

# mkdir -p /etc/swift/

# cp etc/* /etc/swift/

# cd /etc/swift

# for tmpl in *.conf-gluster ; do cp ${tmpl} ${tmpl%.*}.conf; done

Export GlusterFS volumes over gluster-swift

# gluster-swift-gen-builders [VOLUME] [VOLUME...]（命令格式）

# gluster-swift-gen-builders swift-test-vol-01 （命令实例）

Start gluster-swift

# swift-init main start

Using gluster-swift

Create a container

# curl -i -X PUT http://localhost:8080/v1/AUTH_swift-test-vol-01/test-container-01

# ls /mnt/gluster-object/swift-test-vol-01/

Create an object

# echo "Hello Swift" > test.txt

#curl -i -X PUT -T test.txt http://localhost:8080/v1/AUTH_swift-test-vol-01/test-container-01/test.txt

# cat /mnt/gluster-object/swift-test-vol-01/test-container-01/test.txt

Request the object

# curl -i -X GET -o newTest.txt http://localhost:8080/v1/AUTH_swift-test-vol-01/test-container-01/test.txt

#cat newTest.txt

Delete the object

#curl -i -X DELETE http://localhost :8080/v1/AUTH_swift-test-vol-01/test-container-01/test.txt

如果不是GlusterFS服务器，需要先安装以下包：

Installing and starting GlusterFS

# yum install centos-release-gluster

# yum install glusterfs glusterfs-server glusterfs-cli glusterfs-libs glusterfs-client glusterfs-fuse glusterfs-api
