nginx 配置多域名共享 80 端口

#工作进程个数，一般跟服务器cpu核数相等，或者N-1
worker_processes  2;

pid        logs/nginx.pid;

# 单个进程最大连接数

    # sendfile使用高效文件传输，提升传输性能。启用后才能使用tcp_nopush，是指当数据表累积一定大小后才发送，提高了效率。
    sendfile        on;
    # tcp_nopush 与 tcp_nodelay 互斥
    tcp_nopush     on;
    # keepalive_timeout设置客户端与服务端请求的超时时间，保证客户端多次请求的时候不会重复建立新的连接，节约资源损耗。
    keepalive_timeout  65;
    # gzip启用压缩，html/js/css压缩后传输会更快
    gzip  on;
