Nginx证书卸载

server {
    listen 192.168.159.131:808 ssl;
    server_name listen_aaaa;
    keepalive_timeout 60;
    ssl_certificate /usr/local/nginx/ca/server/server.crt;
    ssl_certificate_key /usr/local/nginx/ca/server/server.key;
    ssl_client_certificate /usr/local/nginx/ca/private/ca.crt;
    ssl_verify_client on;
    ssl_session_timeout 5m;
    ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
    ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
    ssl_prefer_server_ciphers on;
    location / {
      proxy_pass http://192.168.159.131:8080;
      proxy_redirect http:// https://;
      proxy_set_header Host $host:$server_port;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

proxy_pass 使用的是http://, 也就是说访问监听器的时候使用的是https的双向证书访问，但是访问后端server的时候没有证书加密使用的是http的访问方式。这个状态为证书卸载状态

不卸载证书即访问监听器的时候是https访问，监听器转发到后端server的时候依旧是使用https去访问，具体配置如下：

server {
    listen 192.168.159.131:808 ssl;
    server_name listen_aaaa;
    keepalive_timeout 60;

    ssl_certificate /usr/local/nginx/ssl/server.crt;
    ssl_certificate_key /usr/local/nginx/ssl/server.key;
    ssl_client_certificate /usr/local/nginx/ssl/ca.crt;
    ssl_verify_client on;
    ssl_session_timeout 5m;
    ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
    ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
    ssl_prefer_server_ciphers on;
    location / {
      proxy_pass https://192.168.159.131:443;
      proxy_redirect http:// https://;
      proxy_set_header Host $host:$server_port;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
  }
  server {
    listen 192.168.159.131:443 ssl;
    server_name listen_123456;
    keepalive_timeout 60;

    ssl_certificate /usr/local/nginx/ssl/server.crt;
    ssl_certificate_key /usr/local/nginx/ssl/server.key;
    ssl_session_timeout 5m;
    ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
    ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
    ssl_prefer_server_ciphers on;
    location / {
      proxy_pass http://strategy-1462610083074666496_pool;
      proxy_redirect http:// https://;
      proxy_set_header Host $host:$server_port;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

1，监听器808（单向证书/双向证书），proxy_pass https://使用的是https，关联的后端server为443是一个https类型的后端server（单向证书）。浏览器访问成功

2，监听器808（单向证书/双向证书），proxy_pass https://使用的是https，关联的后端server为443是一个https类型的后端server（双向证书）。浏览器访问成功

可以参考链接配置，本人没有配置成功，出现这种情况：
1，启动nginx，加入相应配置，浏览器测试成功。
2，修改 proxy_ssl的参数配置，reload之后访问失败，把配置再改回原来的配置，reload之后再浏览器访问，访问失败。把nginx停止后重新启动再去访问，访问成功，不知道啥原因。
