【OpenStack】OpenStack系列3之Swift详解

1. Swift安装部署（与keystone依赖包有冲突，需要安装不同版本eventlet）

   参考：http://www.server110.com/openstack/201402/6662.html

   https://github.com/yongluo2013/osf-openstack-training/blob/master/installation/openstack-icehouse-for-centos65.md

   http://www.server110.com/openstack/201402/6662.html

   1. 源码下载
      1. git clone -b stable/icehouse https://github.com/openstack/swift.git
   2. 安装
      1. pip install -r requirements.txt
      2. python setup.py install
   3. 准备工作
      1. 安装xfs：yum install xfsprogs xinetd –y
      2. 新磁盘数据存储：

         mkfs.xfs /dev/sdb1

         echo "/dev/sdb1 /srv/node/sdb1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 0" >> /etc/fstab

         mkdir -p /srv/node/sdb1

         mount /srv/node/sdb1

         chown -R root:root /srv/node

      3. 配置文件修改

         cp account-server.conf-sample account-server.conf

         cp container-server.conf-sample container-server.conf

         cp object-server.conf-sample object-server.conf

      4. 设置rsync

      5. 安装proxy服务
         1. 参考：

            https://github.com/yongluo2013/osf-openstack-training/blob/master/installation/openstack-icehouse-for-centos65.md

         2. 安装memcached：yum install memcached –y
      6. Swift的日志配置

         参考：https://lists.launchpad.net/openstack/msg20224.html

         http://blog.csdn.net/robberboyboy/article/details/8639021

      7. 启动proxy：./bin/swift-proxy-server /etc/swift/proxy-server.conf（需要权限）

         swift-init proxy-server start，开启8080端口。

      8. 启动object、container、account服务。参考：

         https://github.com/yongluo2013/osf-openstack-training/blob/master/installation/openstack-icehouse-for-centos65.md

         swift-init all start，依次占用6000、6001、6002端口。

      9. 安装python-swiftclient

         git clone https://github.com/openstack/python-swiftclient.git

         问题可以在openstack官网论坛搜索：

         https://ask.openstack.org/en/question/57608/proxy-server-error-insufficient-storage-10001556002sdb1/

      10. 简单测试

          Stat、container、文件上传、下载、删除等

2. 与Glance对接

   2. Glance对接swift

      glance image-create --progress --name="CirrOS 0.3.0" --disk-format=qcow2 --container-format=ovf --is-public=true < image-dir/cirros-0.3.0-x86_64-disk.img

      glance image-create --name "cirros-0.3.3-x86_64" --file image-dir/cirros-0.3.3-x86_64-disk.img --disk-format qcow2 --container-format ovf --is-public=true --progress

      glance image-list

      swift list
