nginx(一）之默認配置文件

首先是nginx.conf

vim /etc/nginx/nginx.conf


user  nginx;                      // 設置nginx服務的系統使用用戶
worker_processes  1;       // 工作進程數

error_log  /var/log/nginx/error.log warn;  // nginx的錯誤日志
pid        /var/run/nginx.pid;      // nginx服務啟動時候pid


events {                                                      // 事件模塊，nginx優勢利用epoll內核模型，在這里可以配置使用哪個內核模型
    worker_connections  1024;               // 每個進程允許最大連接數 ，還有個use是工作進程數
}


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

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '     // 定義日志類型
                      '$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;   // 服務端超時時間

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;      // 讀到這個地方是加載另一個默認配置配置文件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;  // 默認加載根路徑文件
    }

    #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;

http可以包含多個http服務，一個server配置一個獨立的站點。一個http可以有多個server,一個server可以有多個location匹配資源路徑
