6.3 安装配置Swift的代理节点
6.3.1 安装swift-proxy服务
# yum install openstack-swift-proxy memcached python-keystone openstack-utils python-keystoneclient
可以安装在单个节点上
6.3.2 启动memcached服务
通过/etc/sysconfig/memcached配置文件为memcached服务配置好合适的参数后即可启动此服务。
# service memcached start
# chkconfig memcached on
[root@localhost ~]# cat /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS=""
# cd /etc/swift #一定要进入到该目录执行下面的目录
# swift-ring-builder account.builder create 18 3 1
# swift-ring-builder container.builder create 18 3 1
# swift-ring-builder object.builder create 18 3 1
上面的命令后面三个参数中，18表示构建一致hash环时其环的大小，即使用2^18大小的环。实际使用中，可以根据节点数规模进行调整，最大为32；3表示为每个对象存储3个副本；最后的1表示多长时间可以移动一次某partiton。
6.3.5 将存储设备关系至ring
在ring文件创建完成后，还需要将每个存储设备添加至每个ring上，而且通常需要以account、container和object的顺序进行。其格式为：
# swift-ring-builder account.builder add z<ZONE>-<STORAGE_LOCAL_NET_IP>:6002/<DEVICE> 100
# swift-ring-builder container.builder add z<ZONE>-<STORAGE_LOCAL_NET_IP_1>:6001/<DEVICE> 100
# swift-ring-builder object.builder add z<ZONE>-<STORAGE_LOCAL_NET_IP_1>:6000/<DEVICE> 100
其中<ZONE>为zone编号，如z1表示第一个zone；<STORAGE_LOCAL_NET_IP>表示存储节点自己的IP地址；<DEVICE>表示对应设备的设备名称或挂载点名称(二者通常相同)，如/dev/sdb1设备的挂载点为/srv/node/sdb1时，其<DEVICE>即为sdb1。因此，将sdb1、sdc1和sdd1三个设备添加至ring文件可通过如下命令实现。
# swift-ring-builder account.builder add z1-172.18.109.237:6002/sdb1 100
# swift-ring-builder container.builder add z1-172.18.109.237:6001/sdb1 100
# swift-ring-builder object.builder add z1-172.18.109.237:6000/sdb1 100
# swift-ring-builder account.builder add z2-172.18.109.237:6002/sdc1 100
# swift-ring-builder container.builder add z2-172.18.109.237:6001/sdc1 100
# swift-ring-builder object.builder add z2-172.18.109.237:6000/sdc1 100
# swift-ring-builder account.builder add z3-172.18.109.237:6002/sdd1 100
# swift-ring-builder container.builder add z3-172.18.109.237:6001/sdd1 100
# swift-ring-builder object.builder add z3-172.18.109.237:6000/sdd1 100
查看每个ring文件的内容，验正添加结果：
# swift-ring-builder account.builder
