2.修改 /etc/hosts文件
增加映射 127.0.0.1 yes.oktokeep.com
3.创建nodejs文件，模拟4个应用，文件内容一样，仅仅端口号不同
8881.js(同理创建8882.js,8883.js,8884.js文件)
var http = require("http");
http.createServer(function(request,response){
response.writeHead(200,{"Content-Type":"text/plain"});
response.write("Hello Nignx,I am warking on port 8881.\n");
response.end();
}).listen(8881);
console.log("nodejs start listen 8881 port!\n");
var http = require("http");
http.createServer(function(request,response){
response.writeHead(200,{"Content-Type":"text/plain"});
response.write("Hello Nignx,I am warking on port 8882.\n");
response.end();
}).listen(8882);
console.log("nodejs start listen 8882 port!\n");
var http = require("http");
http.createServer(function(request,response){
response.writeHead(200,{"Content-Type":"text/plain"});
response.write("Hello Nignx,I am warking on port 8883.\n");
response.end();
}).listen(8883);
console.log("nodejs start listen 8883 port!\n");
var http = require("http");
http.createServer(function(request,response){
response.writeHead(200,{"Content-Type":"text/plain"});
response.write("Hello Nignx,I am warking on port 8884.\n");
response.end();
}).listen(8884);
console.log("nodejs start listen 8884 port!\n");
4.启动nginx, node 8881.js &
5.模拟请求
上传3份nodejs文件
node /usr/workspace/nodejs/8881.js &
node /usr/workspace/nodejs/8882.js &
node /usr/workspace/nodejs/8883.js &
node /usr/workspace/nodejs/8884.js &
##使用轮询的方式来访问
