nginx默认的配置文件详解

# For more information on configuration, see:#   * Official English Documentation: http://nginx.org/en/docs/#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;# 运行用户，默认是nginx

worker_processes auto;# nginx进程数,一般设置为和cpu核数一样

error_log /var/log/nginx/error.log;# 全局错误日志路径

pid /run/nginx.pid;# 进程pid路径

# Load dynamic modules. See /usr/share/nginx/README.dynamic.# 负载动态模块include /usr/share/nginx/modules/*.conf;

events {# 工作模式与连接数上限    worker_connections 1024;   # 单个进程的最大连接数}

http {# 设置http服务器    log_format  main  ‘$http_host $server_addr $remote_addr [$time_local] "$request" $status  $request_body  $body_bytes_sent "$http_referer" "$http_user_agent" $request_time $upstream_response_time‘;    # 设置日志的格式

access_log  /var/log/nginx/access.log  main;    # 访问日志的路径

sendfile            on;    # 开启高效传输模式    tcp_nopush          on;    # 激活tcp_nopush参数可以允许把http response header和文件的开始放在一个文件里发布，作用是减少网络报文段的数量    tcp_nodelay         on;    # 激活tcp_nodelay，内核会等待将更多的字节组成一个数据包，从而提高I/O性能    keepalive_timeout   65;    # 长连接超时时间，单位是秒    types_hash_max_size 2048;    # 为了快速处理静态数据集，例如服务器名称， 映射指令的值，MIME类型，请求头字符串的名称，nginx使用哈希表
