nginx配置https，并设置代理转发

 将crt和key配置路径配置按如下配置即可。

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

        ssl_certificate "/etc/nginx/server.crt";
        ssl_certificate_key "/etc/nginx/server.key";
        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 /management/ {
                  proxy_redirect off;
                  proxy_set_header Host $host;
                  proxy_set_header X-Real-IP $remote_addr;
                  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                  proxy_pass http://127.0.0.1:9001/management/;
              }

        location /b2c/ {
                  proxy_redirect off;
                  proxy_set_header Host $host;
                  proxy_set_header X-Real-IP $remote_addr;
                  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                  proxy_pass http://127.0.0.1:9001/b2c/;
              }

        location /file/images/ {
                  proxy_redirect off;
                  proxy_set_header Host $host;
                  proxy_set_header X-Real-IP $remote_addr;
                  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                  proxy_pass http://127.0.0.1:9001/file/images/;
              }

       location / {

        }

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

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

注：由于我的服务是为服务，需要从https转发到网关。所以配置了代理转发，之间出现了权限的问题，负载均衡报错failed (13: Permission denied) while connecting to upstream,始终转发失败。解决办法如下：

1.修改nginx.conf配置文件，将第一行的user nginx改成root

2.检查网络访问的配置

getsebool -a | grep httpd_can_network_connect

如果结果是httpd_can_network_connect --> off，则需要修改成on

修改方法

（1）临时修改，SELinux命令，临时配置，重启后失效：etsebool httpd_can_network_connect=1

（2）写入配置文件的命令，重启后保留：setsebool -P httpd_can_network_connect 1

3.修改selinux

查看是否启用：sestatus -v

若显示的是SELinux status: enabled则表示已开启。

（1）临时修改：setenforce 0 表示permissive (setenforce 1 )代表enforcing（强制）

（2）永久关闭：vim /etc/selinux/config，将SELINUX=enforcing改为SELINUX=disabled

记得重启nginx，以上三种方法应该能解决此问题。
