• Nginx重启警告

hash_max_size，hash_bucket_size nginx: [warn] could not build optimal proxy_headers_hash, you should increase either proxy_headers_hash_max_size: 512 or proxy_headers_hash_bucket_size: 64; ignoring proxy_headers_hash_bucket_size

两个的size根据自已系统后端发送的header来进行设置，最好不要设置默认值，否则会报错

• 解决办法
  编辑vim /etc/nginx/nginx.conf，在http里面增加

proxy_headers_hash_max_size 51200;
proxy_headers_hash_bucket_size 6400;
