Answer 1

可能是配置问题。另一种可能是您当前的实例没有 SES 权限。我不太确定这是否是正确的答案。但你可以尝试一下。 @使用SES功能创建工作实例的新AMI镜像。并从该 AMI 启动新实例。并检查它。

另一种可能性是:

MYSQL 和 APACHE 服务器应处于运行模式。

对于 MYSQL 服务器:

/etc/init.d/mysqld status

如果未启动则运行

/etc/init.d/mysqld start

对于 Centos 上的 Apache 服务器:

/etc/init.d/httpd status

如果未启动则运行

 /etc/init.d/httpd start
