你好，我尝试在我的 vServer 上安装 Discourse，该服务器上运行着 mailcow-dockerized，并且位于 nginx 反向代理之后。
但安装失败，我认为问题出在 Redis 上。mailcow 也使用了一个 Redis 容器。
在 Discourse 安装过程中，我从 Redis 收到以下错误：
# 无法创建服务器 TCP 监听套接字 *:6379: bind: 地址已在使用中
这很可能是另一个 Redis 容器导致的问题：
6c26bfa0f7f8 redis:5-alpine "docker-entrypoint.s…" 17 hours ago Up 17 hours 127.0.0.1:7654->6379/tcp mailcowdockerized_redis-mailcow_1
inspect 命令显示了以下网络部分：
},
"NetworkMode": "mailcowdockerized_mailcow-network",
"PortBindings": {
"6379/tcp": [
{
"HostIp": "127.0.0.1",
"HostPort": "7654"
}
]
},
最终我得到以下输出：
