我在尝试将symfony5应用程序与heroku上的redis服务器连接时遇到了一个问题。
-我的composer.json和composer.lock设置了ext redis:“*”。

"require": {
        "php": "~7.4.0",
        "ext-ctype": "*",
        "ext-iconv": "*",
        "ext-intl": "*",
        "ext-openssl": "*",
        "ext-redis": "*",
        ...
}

我在heroku上有3个配置变量：
heroku redis模块激活后创建的默认var
redis\u url=redis://h:somehash@ec2.eu-west-1.compute.amazonaws.com:27269
定制var以适应php类redis构造函数
redis\u主机=redis://h:somehash@ec2.eu-west-1.compute.amazonaws.com
redis\u端口=27269
我的部署由于以下错误而停止：找不到套接字传输“redis”-配置php时是否忘记启用它？
