时间：2022-11-06 00:15:03

以下配置为产品环境的nginx基于安全和效率的主配置文件,不包含fastcgi相关配置

cat /etc/nginx/nginx.conf

user                   nginx;

worker_processes       auto;

error_log              /var/log/nginx/error.log;

pid                    /run/nginx.pid;

include                /usr/share/nginx/modules/*.conf;

events {

    use                epoll;

    multi_accept       on;

    worker_connections 2048;

}

http {

   # 基本安全设置

    ## 1.不返回版本号

    server_tokens       off;

    ## 2.只允许同源的fram/iframe/object加载,避免劫持

    add_header          X-Frame-Options SAMEORIGIN;

    ## 3.关闭资源类型猜想,避免资源代码攻击

    add_header          X-Content-Type-Options nosniff;

    ## 4.开启XSS过滤,若检查到XSS攻击,停止渲染页面

    add_header          X-XSS-Protection "1; mode=block";

   # 配置文件包含和媒体文件包含

    include             /etc/nginx/conf.d/*.conf;

    include             mime.types;

    default_type        application/octet-stream;

   # sendfile和tcp连接设置

    sendfile            on;

    tcp_nopush          on;

    tcp_nodelay         on;

    keepalive_timeout   65;

    types_hash_max_size 2048;

   # 开启gzip压缩

    gzip                on;

    gzip_min_length     5k;

    gzip_buffers        4 16k;

    gzip_comp_level     2;

    gzip_vary           on;

   # 设定请求大小和缓冲大小

    client_max_body_size        100m;

    client_body_buffer_size     8K;

    client_header_buffer_size   64k;

    large_client_header_buffers 4 128k;

   # 防DDOS攻击配置

    ## 2.同一IP总共最多存在50个并发

    limit_conn_zone $binary_remote_addr zone=TCLZone:20m ;

    limit_conn_log_level notice;

    limit_conn  TCLZone  50;

    ## 3.同一IP每秒最多处理10个请求,5个排队

    limit_req_zone $binary_remote_addr  zone=CLZone:20m rate=10r/s;

    limit_req_log_level notice;

    limit_req zone=CLZone burst=5 nodelay;

   # 日志格式及日志路径,产品环境用json格式,其他环境用默认

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

                        '$status $body_bytes_sent "$http_referer" '

                        '"$http_user_agent" "$http_x_forwarded_for"';

    log_format main_json '{"@timestamp":"$time_local",'

                         '"N_request": "$request",'

                         '"N_request_time": "$request_time",'

                         '"N_status": "$status",'

                         '"N_bytes": "$body_bytes_sent",'

                         '"N_user_agent": "$http_user_agent",'

                         '"N_x_forwarded": "$http_x_forwarded_for",'

                         '"N_referer": "$http_referer"'

                         '}';

    access_log  /var/log/nginx/access.log  main_json;

   # 禁止使用IP解析,禁止非法域名解析

    server {

        listen 80;

        server_name - ;

        return 501;

    }
