问题描述
我正在尝试在服务器上使用websocket。问题似乎是我的证书，但错误消息显示PHP正在搜索我未指定的文件。直接在下面的是下面进一步给出的代码的输出。请参考https://www.php.net/manual/en/context.ssl.php进行参考。
8888
WSS
Context Created
stream_socket_server Created
....1,stream would like to be processed.
PHP Warning: stream_socket_accept(): Unable to set private key file '/etc/letsencrypt/archive/example.org/fullchain1.pem' in /var/www/carbonPHP.com/server.PHP on line 108
PHP Warning: stream_socket_accept(): Failed to enable crypto in /var/www/example.com/server.PHP on line 108
PHP Warning: stream_socket_accept(): accept Failed: Success in /var/www/example.com/server.PHP on line 108
stream_socket_accept Failed
我正在查看以上文档，并尝试了许多不同的配置组合。查看上面的代码和输出，我看到它正在搜索'fullchain1.pem'，但是我为 stream_context_create 提供了'fullchain.pem'。当用户实际连接时，它不会被使用并在 stream_select 之前发出警告。 Safari实际上为我提供了错误消息 WebSocket网络错误：Osstatus错误-9806 的详细信息。这是一个通用的连接错误，因为PHP失败了。我使用let-encrypt生成密钥文件，并进行了一些探索，使我进入了该文件夹。我已经尝试了所有文件，但没有一个起作用。
root@blackhat:/etc/letsencrypt/live/example.org# ls
README cert.pem chain.pem fullchain.pem fullchain1.pem privkey.pem
root@blackhat:/etc/letsencrypt/live/example.org# rm fullchain1.pem
root@blackhat:/etc/letsencrypt/live/example.org# cat README
This directory contains your keys and certificates.
`privkey.pem` : the private key for your certificate.
`fullchain.pem`: the certificate file used in most server software.
`chain.pem` : used for OCSP stapling in Nginx >=1.3.7.
`cert.pem` : will break many server configurations,and should not be used
without reading further documentation (see link below).
移至代码。 *请知道SSL已关闭，该服务才能在tcp上正确运行。

有人知道为什么要在文件名上重复1或将其追加吗？或者只是如何解决此问题？预先感谢您的帮助！
