Question

我目前正在研究CloudFormation项目，以构建容错架构。快照出现问题。我试图使用EBS快照来存储数据，因此当一个实例关闭时，另一实例可以通过自动缩放从快照加载数据。任何人都可以提出一些想法吗？

SnapshotId是由我们自己编写的，为什么在创建堆栈后在控制台中看不到它？

LaunchConfig:
Type: AWS::AutoScaling::LaunchConfiguration
Properties:
  ImageId: ami-33f92051
  InstanceType: t2.micro
  AssociatePublicIpAddress: 'true'   #auto-assign public ip 
  KeyName: 
    Ref: KeyName
  SecurityGroups:
  - Ref: PublicEC2instancesSecurityGroupJing
  BlockDeviceMappings:
  - DeviceName: "/dev/xvda"
    Ebs:
      SnapshotId: snap-0821cc7c34fcb7b01
      VolumeSize: 8
  UserData:
    Fn::Base64:
      Fn::Join:
      - "\n"
      - - "#!/bin/bash -xe"
        - sudo yum update -y
        - sudo yum install httpd24 php56 php56-mysqlnd -y
        - sudo yum install mysql -y
        - sudo service httpd start
        - echo "<html><body><h1>Testing page !!!</h1>" >> /var/www/html/index.html
        - echo "</body></html>" >> /var/www/html/index.html

尝试将EFS用作中间存储并将其安装到每个实例。此外，您可以将S3存储桶用于此类数据。 S3也可以作为文件系统安装到实例。

要挂载EFS，您需要安装<div class="list-group" id="sidebar"> <a href="#menu1" class="list-group-item" data-toggle="collapse">Item 1 <i class="fa fa-caret-down"></i></a> <div class="collapse" id="menu1" data-parent="#sidebar"> <a href="#menu1sub1" class="list-group-item" data-toggle="collapse">Subitem 1 <i class="fa fa-caret-down"></i></a> <div class="collapse" id="menu1sub1" data-parent="#menu1sub1"> <a href="#" class="list-group-item">Subitem 1 a</a> <a href="#" class="list-group-item">Subitem 2 b</a> <a href="#menu1sub1sub1" class="list-group-item" data-toggle="collapse">Subitem 3 c <i class="fa fa-caret-down"></i></a> <div class="collapse" id="menu1sub1sub1"> <a href="#" class="list-group-item">Subitem 3 c - item 1</a> <a href="#" class="list-group-item">Subitem 3 c - item 2</a> </div> <a href="#" class="list-group-item" data-parent="#menu1sub1">Subitem 4 d</a> <a href="#menu1sub1sub2" class="list-group-item" data-toggle="collapse">Subitem 5 e <i class="fa fa-caret-down"></i></a> <div class="collapse" id="menu1sub1sub2" data-parent="#menu1sub1sub2"> <a href="#" class="list-group-item">Subitem 5 e.1</a> <a href="#" class="list-group-item">Subitem 5 e.2</a> </div> </div> <a href="#" class="list-group-item" data-parent="#menu1">Subitem 2</a> <a href="#" class="list-group-item" data-parent="#menu1">Subitem 3</a> </div> <a href="#" class="list-group-item" data-parent="#sidebar">Item 2</a> <a href="#menu3" class="list-group-item" data-toggle="collapse">Item 3 <i class="fa fa-caret-down"></i></a> <div class="collapse" id="menu3" data-parent="#sidebar"> <a href="#" class="list-group-item">3.1</a> <a href="#menu3sub2" class="list-group-item" data-toggle="collapse">3.2 <i class="fa fa-caret-down"></i></a> <div class="collapse" id="menu3sub2" data-parent="#menu3"> <a href="#" class="list-group-item">3.2 a</a> <a href="#" class="list-group-item">3.2 b</a> <a href="#" class="list-group-item">3.2 c</a> </div> <a href="#" class="list-group-item" data-parent="#menu3">3.3</a> </div> <a href="#" class="list-group-item" data-parent="#sidebar">Item 4</a> <a href="#" class="list-group-item" data-parent="#sidebar">Item 5</a> </div>
为了将S3存储桶安装到您的实例，您需要安装do 下一个：

amazon-efs-utils

sudo yum install automake fuse fuse-devel gcc-c++ git libcurl-devel libxml2-devel make openssl-devel

安装必需的工具后，尝试安装存储桶

git clone https://github.com/s3fs-fuse/s3fs-fuse.git
cd s3fs-fuse
./autogen.sh
./configure --prefix=/usr --with-openssl
make
sudo make install

将此过程添加到您的用户数据中，并将在每次启动新实例或创建自定义AMI后完成。
