Laravel 回显服务器未显示任何客户端已连接？
Laravel echo server not showing any client connected?
Laravel echo 服务器在开发环境中工作，但在生产环境中不工作...
我打开我的网页，应该接收从 laravel 回显服务器广播的事件。因此，浏览器控制台不会显示 can't connect to ws://domain.com/socket.io/etc 之类的任何错误。服务器端什么都没有，我看不到任何客户端连接...
L A R A V E L E C H O S E R V E R
version 1.4.2
Starting server...
✔ Running at 0.0.0.0 on port 6001
✔ Listening for http events...
✔ Listening for redis events...
Server ready!
我希望看到如下内容：
0|Socket-Connection | [11:17:01 AM] - ********** authenticated for: private-user.1
0|Socket-Connection | [11:17:01 AM] - ********** joined channel: private-user.1
这是我的 resources/assets/js/bootstrap.js:
import Echo from "laravel-echo"
window.io = require('socket.io-client');
if (typeof io !== 'undefined') {
window.Echo = new Echo({
broadcaster: 'socket.io',
host: window.location.hostname + ':6001',
transports: ['websocket', 'polling', 'flashsocket']
});
}
可能发生了什么？
if (typeof window.io !== 'undefined') {
window.Echo = new Echo({
broadcaster: 'socket.io',
host: window.location.hostname + ':6001',
transports: ['websocket', 'polling', 'flashsocket']
});
现在可以使用了！我不确切地知道我做了什么让它工作，也许与 Laravel Queue 或 Redis 相关的问题是问题...
Laravel回显服务器
这是适合我的laravel-echo-server.json：
{
"authHost": "http://11.222.333.44",
"authEndpoint": "/broadcasting/auth",
"clients": [],
"database": "redis",
"databaseConfig": {

}
},
"devMode": false,
"host": null,
"port": "6001",

Laravel队列
另一件肯定是错误的事情：queue:work 进程是从 Supervisor 错误的队列连接 (SQS) 开始的，正如 Laravel Docs:
command=php /home/forge/app.com/artisan queue:work sqs --sleep=3 --tries=3
我不使用 Amazon SQS 作为队列连接，而是默认使用 Redis（在 .env 中指定为 QUEUE_DRIVER），这就是它生成此错误的原因：

所以我通过从 /etc/supervisor/conf.d/laravel-worker.conf 中的 command 中删除 sqs 来修复它，因此它使用默认队列连接启动队列：
command=php /home/forge/app.com/artisan queue:work --sleep=3 --tries=3
然后重启主管：
sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start laravel-worker:*
Redis
此外，我试图存储 Redis 日志文件，由于某些未知原因，它在启动 Redis 时产生错误。因此，我只是决定不再通过在 Redis 配置 (/etc/redis/redis.conf) 中将 logfile 留空来存储日志文件。 PS.: 我已经为 Ubuntu 16.04 安装并配置了 Redis described here.
