配置完成，重启服务

# systemctl restart httpd.service memcached.service

浏览器登录：
   域：   　　   default
   用户名：　　admin
   密码：   　　 admin

swift 对象是否为空判断 swift对象存储搭建_git_02

dashboard 配置完成。

3. 测试

测试1：swift 能否支持大于5G的文件上传？

生成一个6G的文件，上传单个6G的文件

# dd if=/dev/zero of=bigfile-6G bs=1M count=6144
# . admin-openrc
# swift upload container1 bigfile-6G
Object PUT failed: http://controller:8080/v1/AUTH_3b6f963488db4af49e4e0c0d095dd6cf/container1/bigfile-6G 413 Request Entity Too Large   Your request is too large.

报错信息：413 请求实体太大，你的请求太大，看来无法普通上传大于5G的文件
swift 客户端版本：python-swiftclient-3.0.0

采用分段上传的方式：
-S 分段大小（单位：bytes）

# swift upload container1 -S 1000000000 bigfile-6G
bigfile-6G segment 6
bigfile-6G segment 1
bigfile-6G segment 5
bigfile-6G segment 0
bigfile-6G segment 2
bigfile-6G

# swift list container1 
bigfile-6G
testfile

上传成功。

总结：
（1）Swift 对于小的文件，是不分段直接存放的；
（2）对于大文件（超过5G），需要指定大小分段来存放文件，比如6G文件，设置分段为1G，则会被分为 6 段上传到object集群

测试2：新加object节点

这里由于电脑配置原因不再测试，因为我们在创建时，副本为三份，所以在扩展object节点时候，分区要是 3 的倍数。
