CentOS7挂载AWS的S3存储bucket到Linux本地文件目录，使用nginx/openresty直接静态文件方式访问

本文主要是介绍CentOS7挂载AWS的S3存储bucket到Linux本地文件目录，使用nginx/openresty直接静态文件方式访问，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

安装AWS s3fs

yum install epel-release

yum install s3fs-fuse

AWS的S3访问密钥

echo ACCESS_KEY_ID:SECRET_ACCESS_KEY > ${HOME}/.passwd-s3fschmod 600 ${HOME}/.passwd-s3fs

挂载s3存储到/mnt/s3bucket目录，并把文件设置为nginx权限

id nginx
# 查询nginx用户信息
uid=1003(nginx) gid=1003(nginx) groups=1003(nginx)

#挂载s3
s3fs -o uid=1003,gid=1003 static-xxx-pro /mnt/s3bucket -o passwd_file=${HOME}/.passwd-s3fs

设置fstab开机自动挂载s3

s3fs#static-xxx-pro /mnt/s3bucket fuse _netdev,allow_other,uid=1003 ,gid=1003 0 0

查看/mnt/s3bucket目录

ll  /mnt/s3bucket/

nginx/openresty配置

nginx.conf配置内容

server  {listen 80;server_name localhost;location / {alias /mnt/s3bucket/;}
}

原文信息如下：

s3fs

s3fs allows Linux and macOS to mount an S3 bucket via FUSE.
s3fs preserves the native object format for files, allowing use of other
tools like AWS CLI.

Features

large subset of POSIX including reading/writing files, directories, symlinks, mode, uid/gid, and extended attributes
compatible with Amazon S3, Google Cloud Storage, and other S3-based object stores
allows random writes and appends
large files via multi-part upload
renames via server-side copy
optional server-side encryption
data integrity via MD5 hashes
in-memory metadata caching
local disk data caching
user-specified regions, including Amazon GovCloud
authenticate via v2 or v4 signatures

Installation

Many systems provide pre-built packages:

Amazon Linux via EPEL:

sudo amazon-linux-extras install epel
sudo yum install s3fs-fuse

Arch Linux:
```
sudo pacman -S s3fs-fuse
```
Debian 9 and Ubuntu 16.04 or newer:
```
sudo apt install s3fs
```
Fedora 27 or newer:
```
sudo dnf install s3fs-fuse
```
Gentoo:
```
sudo emerge net-fs/s3fs
```

RHEL and CentOS 7 or newer through via EPEL:

sudo yum install epel-release
sudo yum install s3fs-fuse

SUSE 12 and openSUSE 42.1 or newer:
```
sudo zypper install s3fs
```

macOS via Homebrew:

brew cask install osxfuse
brew install s3fs

Otherwise consult the compilation instructions.

Examples

s3fs supports the standard
AWS credentials file
stored in ${HOME}/.aws/credentials. Alternatively, s3fs supports a custom passwd file.

The default location for the s3fs password file can be created:

using a .passwd-s3fs file in the users home directory (i.e. ${HOME}/.passwd-s3fs)
using the system-wide /etc/passwd-s3fs file

Enter your credentials in a file ${HOME}/.passwd-s3fs and set
owner-only permissions:

echo ACCESS_KEY_ID:SECRET_ACCESS_KEY > ${HOME}/.passwd-s3fs
chmod 600 ${HOME}/.passwd-s3fs

Run s3fs with an existing bucket mybucket and directory /path/to/mountpoint:

s3fs mybucket /path/to/mountpoint -o passwd_file=${HOME}/.passwd-s3fs

If you encounter any errors, enable debug output:

s3fs mybucket /path/to/mountpoint -o passwd_file=${HOME}/.passwd-s3fs -o dbglevel=info -f -o curldbg

You can also mount on boot by entering the following line to /etc/fstab:

mybucket /path/to/mountpoint fuse.s3fs _netdev,allow_other 0 0

mybucket /path/to/mountpoint fuse.s3fs _netdev,allow_other 0 0

If you use s3fs with a non-Amazon S3 implementation, specify the URL and path-style requests:

s3fs mybucket /path/to/mountpoint -o passwd_file=${HOME}/.passwd-s3fs -o url=https://url.to.s3/ -o use_path_request_style

or(fstab)

mybucket /path/to/mountpoint fuse.s3fs _netdev,allow_other,use_path_request_style,url=https://url.to.s3/ 0 0

To use IBM IAM Authentication, use the -o ibm_iam_auth option, and specify the Service Instance ID and API Key in your credentials file:

echo SERVICEINSTANCEID:APIKEY > /path/to/passwd

The Service Instance ID is only required when using the -o create_bucket option.

Note: You may also want to create the global credential file first

echo ACCESS_KEY_ID:SECRET_ACCESS_KEY > /etc/passwd-s3fs
chmod 600 /etc/passwd-s3fs

Note2: You may also need to make sure netfs service is start on boot

Limitations

Generally S3 cannot offer the same performance or semantics as a local file system. More specifically:

random writes or appends to files require rewriting the entire object, optimized with multi-part upload copy
metadata operations such as listing directories have poor performance due to network latency
eventual consistency can temporarily yield stale data(Amazon S3 Data Consistency Model)
no atomic renames of files or directories
no coordination between multiple clients mounting the same bucket
no hard links
inotify detects only local modifications, not external ones by other clients or tools
