创建 apache 证书时出错

Question

我有一个 CentOS 服务器，我正在尝试使用以下命令安装 Apache 证书：

certbot --apache -d myDomain.com

但我收到以下错误：

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache
Starting new HTTPS connection (1): acme-v01.api.letsencrypt.org
Obtaining a new certificate
Performing the following challenges:
tls-sni-01 challenge for myDomain.com
Error while running apachectl graceful.

Job for httpd.service invalid.

Cleaning up challenges

    self._reload()

    raise errors.MisconfigurationError(str(err))
MisconfigurationError: Error while running apachectl graceful.

我检查 Apache 是否正在运行：

ps aux|grep httpd
root     16569  0.0  0.0   9064   920 pts/1    S+   14:44   0:00 grep --color=auto httpd

我没有运行 apache 的实例。

你们中的任何人都知道我该如何解决这个错误或者是否有解决方法？

非常感谢您的帮助。

certbot 显然正在尝试启动/重新启动 apache，但失败了。这可能有很多原因，我会首先查找 apache 错误日志并查看它的内容。 （可能不止一个，所以请检查时间戳。）

知道apache是​​否可以启动也很有趣。一个普通的旧 apachectl start 会发生什么？
