# 默认的工作进程 是由nobody用户去执行的, master由root执行
#user  nobody;
# 工作进程的数量 默认为1
worker_processes  2;

# 用于配置日志的输出位置, 可以区分级别输出到不同的文件, 级别从低到高为
# debug info notice warn error crit
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

# 指定进程pid的位置
#pid        logs/nginx.pid;

# 事件
events {
    # 默认采用epoll
    use epoll;
    # 工作进程的最大客户端连接数
    worker_connections  1024;
}

# http协议
http {
    # 导入一个types文件, 里面基本都是请求类型
    include       mime.types;

    # 日志位置
    #access_log  logs/access.log  main;

    # 提升文件传输效率
    sendfile        on;
    # 当数据包累计到一定大小才进行发送,配合sendfile使用
    #tcp_nopush     on;

    # 客户端连接服务器的超时时间(秒)
    #keepalive_timeout  0;
