> apt-get update
2. 安装nodejs
> sudo apt-get install nodejs
3. 因为npm需要访问目录/usr/bin/node下的配置文件，但是nodejs的配置文件又是安装到/usr/bin/nodejs，所以我们这里需要对这两个文件做一个映射。
不映射的话，有时候在查看npm版本时，会报：/usr/bin/env:node No such file or directory的错误
> ln -s /usr/bin/nodejs /usr/bin/node
4. 安装npm
> sudo apt-get install npm
5. 安装websocket-bench
> sudo npm install -g websocket-bench
6. 若需要修改socket.io协议，位置在./usr/local/lib/node_modules/websocket-bench/lib/workers/socketioworker.js第18行
将：
var client = io.connect(this.server, { 'force new connection' : true});
修改为：
var client = io.connect(this.server, { 'force new connection' : true,'transports': ['websocket', 'polling']});
7. 自定义generator.js
/*global module, require*/
/*var logger = require('opt.log');*/
module.exports = {
/**
* Before connection (just for faye)
* @param {client} client connection
*/
beforeConnect : function (client) {
},
/**
* on socket io connect
* @param {client} client connection
* @param {done} callback function(err) {}
*/
onConnect : function (client, done) {
var sid;
client.on("message",function(message,ackServerCallback){
if (ackServerCallback) {
// send ack data to push server
ackServerCallback(message);
}
console.log("Channel:"+message.channel + "---Content: "+ message.content)
});
client.emit('authorize', {"appkey":"43cbbd30-1753-4fdb-8e45-57d86dde378f","userId":"75115","xueting":"","startMillis":1470729381064,"artifactVersion":"0.7"},function(data){
sid = data.sid;
client.emit('subscribe',{"channel":"demo_channel","sid":sid});
});
//done();
},
/**
* send a message
* @param {client} client connection
* @param {done} callback function(err) {}
*/
sendMessage : function (client, done) {
//logger.error('Not implement method sendMessage in generator');
// Your logic
//client.emit('test', { hello: 'world' });
//client.publish('/test', { hello: 'world' });
done();
}
};
8. 运行websocket-bench
> websocket-bench -a 10 -g ./generator.js localhost:9000
