nginx配置文件

Nginx的安装目录下，其默认的配置文件都放在这个目录的conf目录下，主配置文件为nginx.conf，后续对Nginx的使用基本上都是对此配置文件进行相应的修改。.

Nginx的配置文件内容如下：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
    upstream myserver{
        server 192.168.202.128:8080 weight=5;
        server 192.168.202.128:8081 weight=10;
    }
    server {
        listen       80;
        server_name  192.168.202.128;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            proxy_pass http://myserver;
            index  index.html index.htm;
        }

        #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   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;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    server {
        listen       9001;
        server_name  192.168.202.128;

        location ~/edu/ {
            proxy_pass http://127.0.0.1:8080;
        }
        location ~/vod/{
            proxy_pass http://127.0.0.1:8081;
        }
    }

    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

注意：以上配置文件中有很多#，开头的表示注释内容

根据上述文件，可以很明显的将nginx.conf配置文件分为三部分：

1.  全局块：配置服务器整体运行的配置指令
2. events块：影响Nginx服务器与用户的网络连接
3. http块：代理、缓存和日志定义等绝大多数功能和第三方模块的配置

每个部分的具体内容如下图所示：
