nginx/conf/nginx.conf最简配置说明

代码

• nginx/conf/nginx.conf

worker_processes  1; #工作进程个数;一般对应CPU内核对应一个worker_processes;太多反而让效率变差;

# 事件驱动模块;
events {
    worker_connections  1024;#设置每个worker_processes对应多少个联接;
}

# 网络请求模块;
http {
    include       mime.types;#把当前目录中的mime.types配置文件引入到当前配置文件中; mime.types中放置的是请求头,表明请求的后缀在浏览器中是如何作处理的,是下载还是展示;
    default_type  application/octet-stream;#如果浏览器当前请求的文件不包含在`types`中,则是以`application/octet-stream`格式流的方法传递给浏览器;

    sendfile        on;#指的是数据零拷贝,即不需求复制和拷贝,直接

    keepalive_timeout  65;#表示的是保持连接超时的时间;

    # 表示一个服务器虚拟主机vhost的配置;一个nginx可以对应多个主机;一个主机表示一个独立站点,有自己独立的根目录;可以通过不同端口号区分不同的主机;
    server {
        listen       80;#表示当前虚拟主机监听到的端口号;
        server_name  localhost;#当前主机的主机名,可以用域名或主机名;

        # 表示uri,如一个域名后的子目录或子路径;//如`http://fang.com/uri1/uri2.html`中`/uri1/uri2.html`就叫做uri即资源;
        location / {
            root   html;#表示当前uri的根目录;而`html`在这里则是相对目录,相对于当前nginx应用程序的根目录;如当前配置文件在`/usr/local/nginx/conf/nginx.conf`,则是相对于`/usr/local/nginx/`;
            index  index.html index.htm;#表示访问当前uri下的默认页;即如果`/`没有对应的html文件,则取`/index.html`或`/index.htm`;
        }


        error_page   500 502 503 504  /50x.html;#错误页;表示发生服务器错误如500或502或503或504时,会转向到的地址;
        # 表示`/50x.html`的uri资源配置;
        location = /50x.html {
            root   html;#表示当前uri的根目录;
        }

    }

}

• /usr/local/nginx/conf/mime.types

# 显示浏览器要处理的方式对应的文件名;
types {
    text/html                                        html htm shtml;#表示html与htm与shtml要以`text/html`的协议方式来进行解析;
