nginx(一）之默认配置文件

首先是nginx.conf

vim /etc/nginx/nginx.conf


user  nginx;                      // 设置nginx服务的系统使用用户
worker_processes  1;       // 工做进程数

error_log  /var/log/nginx/error.log warn;  // nginx的错误日志
pid        /var/run/nginx.pid;      // nginx服务启动时候pid


events {                                                      // 事件模块，nginx优点利用epoll内核模型，在这里能够配置使用哪一个内核模型
    worker_connections  1024;               // 每一个进程容许最大链接数 ，还有个use是工做进程数
}


http {                                                  
    include       /etc/nginx/mime.types;  //设置contentType
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '     // 定义日志类型
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

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

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;   // 服务端超时时间

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;      // 读到这个地方是加载另外一个默认配置配置文件default.conf
}

default.conf

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;  // 默认加载根路径文件
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
"/etc/nginx/conf.d/default.conf" 45L, 1093C

http能够包含多个http服务，一个server配置一个独立的站点。一个http能够有多个server,一个server能够有多个location匹配资源路径
