按照 -https://forums.aws.amazon.com/thread.jspa?messageID=475840 上给出的步骤进行操作

wget http://s3fs.googlecode.com/files/s3fs-r177-source.tar.gz
tar zxf s3fs-r177-source.tar.gz
apt-get install build-essential libxml2-dev libfuse-dev libcurl4-openssl-dev

'make install'这一步发生错误

它抛出错误 - 表明在 EC2 上安装 S3FS 时 tar 文件已损坏。

【解决方案1】：

相反，要遵循的正确步骤是在同一个 url（在 cmets 中）中提到的

wget http://s3fs.googlecode.com/files/s3fs-1.71.tar.gz
tar xvzf s3fs-1.71.tar.gz
cd s3fs-1.71/
./configure --prefix=/usr
make
make install (as root)

安装后，创建用于通过 EC2 访问 S3 存储桶的凭据和存储

touch /etc/passwd-s3fs && chmod 640 /etc/passwd-s3fs && echo 'AccessKey:SecretKey' > /etc/passwd-s3fs

注意 - AccessKey 和 SecretKey 是与 EC2、S3 关联的 AWS 账户的密钥

/usr/bin/s3fs o-s3 /mnt/

注意-/mnt/-是1要挂载S3存储桶的目录 o-s3 是s3桶的名字

在 ec2 上检查 S3 是否成功挂载

grep s3fs /etc/mtab

预期输出 - s3fs /mnt fuse.s3fs rw,nosuid,nodev 0 0

cd /mnt/
ls

加载存储在 S3 存储桶中的文件
