1.2 Nginx安全优化

1.2.1 隐藏nginx版本信息优化

官方配置参数说明：http://nginx.org/en/docs/http/ngx_http_core_module.html#server_tokens

官方参数：

Syntax: server_tokens on | off | build | string; #后面这俩参数收费的

Default: server_tokens on;

Context: http, server, location

配置举例：

[root@web01 ~]# cat /application/nginx/conf/nginx.conf

worker_processes 1;

events {

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

sendfile off;

keepalive_timeout 65;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for"';

server {

listen 80;

server_name www.nmtui.com;

server_tokens off;

location / {

root html/www;

index index.html index.htm;

}

access_log logs/access_www.log main;

}

}

测试结果：

[root@web01 ~]# curl -I 10.0.0.8
