执行swift stat发现报错503：

[root@controller ~]# . demo-openrc [root@controller ~]# swift statAccount HEAD failed: http://controller:8080/v1/AUTH_8cc1c04a21ae4165a1667e0bd5029831 503 Service Unavailable

查看错误日志/var/log/messages中显示：

原因：在创建并发ring时设置了错误的ip地址说以会连接失败，我是把管理网络地址写成了外部网络地址，排了半天错错误日志就那几句话，一直没有注意看IP。。现在发现居然是写错了地址

解决方法：

1.删除各节点/etc/swift/下所有.gz文件重新创建并发Ring

[root@compute swift]# rm *.gzrm: remove regular file ‘account.ring.gz’? yrm: remove regular file ‘container.ring.gz’? yrm: remove regular file ‘object.ring.gz’? y

2.然后重新创建并发Ring完成后将新的.gz文件复制到每个存储节点

[root@controller swift]# scp *.gz 192.168.100.20:/etc/swift/root@192.168.100.20's password: account.ring.gz                                                                                 100%  451     0.4KB/s   00:00    container.ring.gz                                                                               100%  453     0.4KB/s   00:00    object.ring.gz                                                                                  100%  447     0.4KB/s   00:00

3.上述完成后各节点重新添加权限

chown -R root:swift /etc/swift

4.重启控制节点服务和各存储节点服务

控制节点：

systemctl restart openstack-swift-proxy.service memcached.service

存储节点：

systemctl restart openstack-swift-account.service openstack-swift-account-auditor.service \
openstack-swift-account-reaper.service openstack-swift-account-replicator.service \
openstack-swift-container.service openstack-swift-container-auditor.service \
openstack-swift-container-replicator.service openstack-swift-container-updater.service \
openstack-swift-object.service openstack-swift-object-auditor.service \
openstack-swift-object-replicator.service openstack-swift-object-updater.service

5.重新显示服务状态

[root@controller ~]# swift stat        Account: AUTH_8cc1c04a21ae4165a1667e0bd5029831     Containers: 0        Objects: 0          Bytes: 0X-Put-Timestamp: 1510845652.31045    X-Timestamp: 1510845652.31045     X-Trans-Id: tx9b845b33034f46f686b7f-005a0dacd3   Content-Type: text/plain; charset=utf-8
