linux安装websocketd服务

1.下载

wget https://github.com/joewalnes/websocketd/releases/download/v0.3.0/websocketd-0.3.0-linux_amd64.zip

注意是amd架构

2.解压

unzip websocketd-0.3.0-linux_amd64.zip

3.复制websocketd到/usr/bin

cp ./websocketd /usr/bin/websocketd

4.添加到path

vi /etc/profile

export PATH=$PATH:/usr/bin/websocketd

sudo source /etc/profile

5.启动服务

websocketd --port=8000 ./count.sh

前端链接测试代码：

var ws =new WebSocket('ws://IP:8000');
ws.onopen = function(event){console.log("CONNECT")};
ws.onmessage = function(event){console.log(event.data)};
ws.onerror = function(event){console.log(event)};

count.sh文件内容如下：

#!/bin/bash
for ((COUNT = 1; COUNT <= 10; COUNT++)); do
  echo $COUNT
  sleep 1
done

　　

示例效果如下：
