======================
NodeJS Websocket Benchmarking
## Socket.IO(On MAC OS X)
* 配置 App, Nginx
```
cd socket.io/chat1
npm install
cd socket.io/chat2
npm install
```
nginx.conf 修改:
由于测试时所有 client 都在本机, 而当前稳定版 nginx(1.6.2) 负载均衡算法不包含generic hash, 按 ip_hash 分配会导致所有请求都发到同一个后端节点, 所以需要安装upsteam-hash-module, 按 hash($remote_addr.$remote_port) 负载均衡.
upstream 使用 unix socket地址 (unix:/tmp/chat1.socket) 能减少 local ip port 的使用(系统配置中 net.inet.ip.portrange的设置 )
```
worker_processes 4;
...
events {
worker_connections 65535;
}
http {
...
upstream app {
hash $remote_addr.$remote_port;
#server 127.0.0.1:3000;
#server 127.0.0.1:3001;
server unix:/tmp/chat1.socket;
server unix:/tmp/chat2.socket;
}
map $http_connection $upgrade_requested {
default upgrade;
'' close;
}
...
server{
...
location / {
proxy_buffering off;
proxy_read_timeout 86400s;
proxy_send_timeout 86400s;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_http_version 1.1;
proxy_pass http://app;
root html;
index index.html index.htm;
}
...
}
...
}
```
* 修改 websocket-bench
websocket-bench中依赖版本策略会导致socket.io-client连接方式(transport) fall back到polling, 而不是websocket, 此外，依赖策略导致使用engine.io-client较低版本, 所以需要修改依赖版本及源码
```
npm install -g websocket-bench
```
修改 websocket-bench 中依赖库的版本
```
"socket.io-client": "~1.2.0",
"engine.io-client": "~1.4.2",
"socket.io": "~1.2.0",
```
修改 websocket-bench 源码(lib/workers/socketioworker.js L20)
```
var client = io.connect(this.server, {'transports': ['websocket'], 'force new connection' : true});
```
```
cd {npm global dir}/websocket-bench
npm install
```
* 系统参数调整
最大打开文件数，本地ip端口范围等
```
sudo sysctl -w kern.maxfiles=1048600
sudo sysctl -w kern.maxfilesperproc=1048576
sudo sysctl -w net.inet.ip.portrange.first=10240
ulimit -S -n 1048576
```
* 启动 App, Nginx (均需要调整ulimit)
```
redis-server
cd socket.io/chat1
node .
cd socket.io/chat2
node .
chmod 666 /tmp/chat1.socket
chmod 666 /tmp/chat1.socket
sudo nginx
```
* 启动 websocket-bench
```
websocket-bench -a 100000 -c 100 -g generator.js -m 1 -k -v http://localhost:80
```
