Nginx_简单的集群，Nginx_简单集群

Nginx常用命令(nginx.exe目录下)：

#启动Nginx
start nginx

#重新加载配置文件
nginx -s reload

#平滑关闭
nginx -s quit

#强制关闭
nginx -s stop

TcpServer集群：

• 修改配置文件，相对路径：\nginx-1.14.0\conf\nginx.conf：

  stream {
      upstream localhost{
          server 127.0.0.1:12345;    #集群程序监听地址
          server 127.0.0.1:12346;    #集群程序监听地址
      }
      server {
          listen 12344;    # nginx监听地址
          proxy_pass localhost;
      }
  }

• 创建TcpServer：用python实现，相同的程序修改其监听端口为12346、12345

  import socket
  
  address = ("127.0.0.1", 12345)
  
  
  def tcp_server():
      server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
      server_socket.bind(address)
      server_socket.listen(5)
      print("TcpServer开始监听:{}".format(address))
      while True:
          client_socket, client_address = server_socket.accept()
          msg = client_socket.recv(1024)
          print(client_address, ":", msg.decode())
          client_socket.close()
  
  
  if __name__ == '__main__':
      tcp_server()
  

HttpServer集群：

• 修改配置文件，相对路径：\nginx-1.14.0\conf\nginx.conf：

  http {
  
     upstream myapp {
         server 127.0.0.1:12356;
         server 127.0.0.1:12357;
     }
  
     server {
         listen 8000;     
         location / {
             proxy_pass http://myapp;
         }
      
     }
  }

• 创建HttpServer：用flask实现，相同的程序修改监听端口12356、12357

  import flask
  
  
  app = flask.Flask(__name__)
  
  
  @app.route("/")
  def index():
      msg = flask.request.get_data()
      print(msg)
      return "success"
  
  
  if __name__ == '__main__':
      app.run(host="127.0.0.1", port=12356)
