我正在尝试创建一个自动部署网络服务器的 CloudFormation EC2 部署。 我目前的设置如下：

我的最终目标是实现以下 bash 脚本
#!/bin/bash
yum update -y
yum install -y httpd24 php70 mysql56-server php70-mysqlnd
service httpd start
chkconfig httpd on
usermod -a -G apache ec2-user
chown -R ec2-user:apache /var/www
chmod 2775 /var/www
find /var/www -type d -exec sudo chmod 2775 {} \;
find /var/www -type f -exec sudo chmod 0664 {} \;
echo "<?php echo '<h2>Welcome to COS80001. Installed PHP version: ' .
phpversion() . '</h2>'; ?>" > /var/www/html/phpinfo.php
我在连接默认网页时遇到了一些问题。 我对如何实现嵌入 3 个撇号感到困惑。 我也对 find \; 感到困惑因为 JSON 文件对其使用不满意。
模板固定。 我删除了AWS::CloudFormation::Init 。 在您的用例中，我没有看到这一点。 我修改了它的键、ami 和参数部分，所以你必须将它们调整回原来的样子。 UserData有效，并且正确部署了phpinfo.php 。

我很早就学会了使用 CloudFormation 模板：
我典型的UserData ：
UserData:

'Fn::Sub': |
