/etc/nginx/nginx.conf是默认的没动：user www-data;worker_processes 1;pid /run/nginx.pid;worker_rlimit_nofile 65536;events { worker_connections 7680; # multi_accept on;}http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 0; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # SSL Settings ## ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE ssl_prefer_server_ciphers on; ## # Logging Settings ##log_format main ‘$remote_addr [$time_local] $status ($body_bytes_sent) “$host” “$request” ‘ ‘$upstream_addr’ ; ## # Gzip Settings ## gzip on; gzip_disable “msie6”; # gzip_vary on; # gzip_proxied any; # gzip_comp_level 6; # gzip_buffers 16 8k; # gzip_http_version 1.1; # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*;}复制代码 从sites-enabled导入123.confserver{listen *:1234;access_log /var/log/nginx/access.log main;error_log /dev/null;location / {proxy_http_version 1.1;proxy_set_header Connection “”;proxy_set_header Host $http_host;proxy_set_header Accept-Encoding “gzip, deflate”;proxy_pass https://$http_host$request_uri; }}复制代码 我这边发送http（非https）反代请求到我的vps:1234， 出现了诡异的一幕： 如果host是www.google.com就可以正常200 如果host是www.google.com.hk或者其他任何国名， 就出现了499 错误。 另外把这2个配置文件放在OVH或者其他美国vps上也全部正常。 只有三毛家出现这个问题。
