我正在尝试创建一个实例来运行 apache，并且一切似乎都正常，但是 Web 服务器尚未启动。
手动启动时一切正常。如果我重新启动实例，它不会自动启动 Web 服务器。
我的资源部分包含：

我的 cfn-init.log：
2013-01-23 13:55:58,064 [INFO] Running configSets: default

2013-01-23 13:57:23,102 [INFO] ConfigSets completed
是否缺少了什么，或者应该启动服务？
答案1
以防万一有人遇到这个问题，问题是一个嵌套错误 - services {} 块需要成为 config {} 块的一部分，而不是在同一级别。
