nginx负载均衡

ngxin可以作为静态资源服务器,反向代理服务器,还可以虚拟主机。

nginx配置文件  /nginx/server/conf/nginx.conf

#user nobody;   #代表当前配置文件的权限 通常设置为root

server {
  listen 80;      #代表监听的端口
  server_name localhost;

  #charset koi8-r;

  #access_log logs/host.access.log main;

  location / {    #匹配规则   一个sever下面可以有多个location
    root html;   #root 表示根目录 /nginx/server
    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
26   #
  #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;
35     # 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
42   # concurs with nginx‘s one
43   #
  #location ~ /\.ht {
45     # deny all;
  #}
}

proxy_pass 与 upstream 配合使用可以实现转发

location /group {
  proxy_pass http://fdfs.com;
}

upstream fdfs.com {
  server 10.130.1.101:80;

       client_max_body_size 20m;  #接收的最大传输大小

}
