Nextcloud登录界面输入用户名和密码后报内部故障

一路走来，该碰到基本上都碰到了。经验积累一下吧。

查询~/nextcloud/data/nextcloud.log，找到日志报出如下错误

"Something is wrong with your openssl setup: error:02001002:system library:fopen:No such file or directory, error:2006D080:BIO routines:BIO_new_file:no such file, error:0E064002:configuration file routines:CONF_load:system lib, error:02001002:system library:fopen:No such file or directory, error:2006D080:BIO routines:BIO_new_file:no such file, error:0E064002:configuration file routines:CONF_load:system lib",

**解决：**在~/nextcloud/config/config.php中添加如下代码：

 'openssl' =>  array (
    'digest_alg' => 'sha512',
    'private_key_bits' => 2048,
    'config' => '/etc/ssl/openssl.cnf',
   ),
