我在问题的标题中收到了错误消息，或者确切地说，我收到了这条消息
PHP Startup: Unable to load dynamic library 'openssl'
(tried: /usr/lib/php/20170718/openssl (/usr/lib/php/20170718/openssl:
cannot open shared object file: No such file or directory),
/usr/lib/php/20170718/openssl.so (/usr/lib/php/20170718/openssl.so: cannot
open shared object file: No such file or directory)) in Unknown
我真正的问题是它只是有时发生而不是总是发生。一秒钟后，一个请求有效，而在另一秒钟内，我在同一请求上收到此消息的 500 内部错误。
这在我启用 apache proxy 和 proxy_wstunnel mod 后开始发生，但也可能是 apt-get upgrade 或 apt-get 更新。

最佳答案
我遇到了同样的问题。
好像是手动创建的
extension=openssl
在 php.ini 中。再次禁用它后一切看起来都很好
php -i | grep -i openssl
SSL Version => OpenSSL/1.1.0g
openssl
OpenSSL support => enabled
OpenSSL Library Version => OpenSSL 1.1.0g 2 Nov 2017
OpenSSL Header Version => OpenSSL 1.1.0g 2 Nov 2017
Openssl default config => /usr/lib/ssl/openssl.cnf
openssl.cafile => no value => no value
openssl.capath => no value => no value
Native OpenSSL support => enabled
