服务端启用证书时的接口请求

服务器配置

    server {
        listen       443 ssl http2 default_server;
        listen       [::]:443 ssl http2 default_server;
        server_name  api.iot.com;
        root         /usr/share/nginx/html;

        ssl_certificate "/etc/pki/nginx/server.crt";
        ssl_certificate_key "/etc/pki/nginx/private/server.key";
        #ssl_client_certificate "/etc/pki/nginx/ca.crt";
        #ssl_verify_client on;
        #ssl_verify_depth 2;
        #ssl_session_cache shared:SSL:1m;
        #ssl_session_timeout  10m;
        #ssl_ciphers HIGH:!aNULL:!MD5;
        #ssl_prefer_server_ciphers on;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

服务端证书配置(去除私钥密码以解决nginx启动报错)

[root@ip-172-31-47-53 ~]# cat ca/intermediate/certs/api.iot.com.cert.pem > /etc/pki/nginx/server.crt
[root@ip-172-31-47-53 ~]# cat ca/intermediate/certs/ca-chain.cert.pem >> /etc/pki/nginx/server.crt
[root@ip-172-31-47-53 ~]# openssl rsa -in ca/intermediate/private/api.iot.com.key.pem -out /etc/pki/nginx/private/server.key
Enter pass phrase for ca/intermediate/private/api.iot.com.key.pem:
writing RSA key
[root@ip-172-31-47-53 ~]#

检查配置

[root@ip-172-31-47-53 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@ip-172-31-47-53 ~]#

重新加载配置

[root@ip-172-31-47-53 ~]# systemctl restart nginx

客户端发起HEAD请求

准备客户端验证CA证书链文件

[root@ip-172-31-47-53 ~]# cat ca/intermediate/certs/ca-chain.cert.pem > /etc/pki/nginx/ca.crt

检查配置文件并重启nginx服务

[root@ip-172-31-47-53 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@ip-172-31-47-53 ~]# systemctl restart nginx
