Answer 1

从编译结果可以看出问题出在你的OpenSSL的版本太低，具体是低于1.1.0，你可以安装高版本的openssl和openssl-devel之后再重新安装uwsgi。

主要是从下面的编译错误提示发现问题出在这个函数调用OPENSSL_config(NULL)。：

core/ssl.c: In function ‘uwsgi_ssl_init’:
core/ssl.c:17:9: error: ‘OPENSSL_config’ is deprecated [-Werror=deprecated-declarations]

然后查看uwsgi代码core/ssl.c（https://github.com/unbit/uwsg...）可以发现下面语句：

void uwsgi_ssl_init(void) {
#if OPENSSL_VERSION_NUMBER < 0x10100000L
        OPENSSL_config(NULL);
#endif
        SSL_library_init();
        SSL_load_error_strings();
        OpenSSL_add_all_algorithms();
        uwsgi.ssl_initialized = 1;
}

其中宏定义表示openssl版本小于1.1.0时才会调用已经废弃的OPENSSL_config函数。
所以安装1.1.0以上版本的openssl应该可以解决问题。
