使用 ossfs 迁移非结构数据
1、非结构化数据到 OSS 迁云: ossfs 迁云实践
（1）前提
完成 OSS bukect 创建
AK 创建及 OSS 权限分配
（2）运行环境
CentOS 7.2 64bit
eossfs_1.80.3 centos7.0_x86_64
2、非结构化数据到 OSS 迁云:步骤
（1）安装 ossfs
获取 ossfs 安装包
#wget-o“ossfs1.80.3centos7.0x8664rpm
”http://docs-aliyuncn-hangzhou.oss.aliyun-
inc.com/assets/attach/32196/cnzh/1507811577850/ossfs1803 centos70x86 64rpm?spm=5176doo
32196.2.6.A0qxWs&file=ossfs180.3centos7.0x8664rpm
（2）配置 OSS 信息
设置 bucket name 和 AccessKeyId/Secret 信息，将其存放在 /etc/passwd-ossfs 文件中，注意这个文件的权限必须正确设置，建议设为 640。
（3）挂载 OSS 至本地目录
将 OSSbucket mount 到指定目录
# ossfs my-bucket my-mount-point-ourl=my-oss-endpoint
（4）复制源站非结构化数据
复制源站非结构化数据至 OSS 挂载目录
打开 OSS 控制台查看结果
3、演示
（1）获取 ossfs 并安装
wget -0 "ossfs 1.80.3 centos7.0 x86 64.rpm"
http://docs-aliyun.cn-hangzhou.oss.aliyun-inc.com/assets/attach/32196/cn zh/1507811577850/ossfs 1.80.3 centos7.0 x86 64.rpm?spm=5176.doc32196.2.6.A QqxWs&file=ossfs 1.80.3 centos7.0 x86 64.rpm
yum -y localinstall
ossfs 1.80.3 centos7.0 x86 64.rpm
（2）设置 bucket name 和 AccessKeyId/Secret 信息
echo ossfs-edu:xxxx:Ra7gMHOdzV8gZQjXDdp 6t0 WAzZ9xoa >/etc/passwd-ossfs
（3）配置权限
chmod 640 /etc/passwd-ossfs
（3）将 osS bucket mount 到指定目录
ossfs ossfs-edu /mnt
