@merefield 我应该担心这些吗？

是的，你应该这样做。

redis-cli ping 的输出是什么？

709

我明天再回复你（今天有点忙）

710

它输出 PONG。
@merefield 我认为这意味着它没问题？有什么关于为什么它会超时然后又好的想法吗？

您是建议我将 Docker 降级到提到的版本吗？

714

嗯……好的。只有一个问题：我没有使用 Docker。看来我只能遵循本指南了……

715

当然不是！:facepalm: 那是错误的建议，已删除。

从你的回复来看，Redis 正在响应并运行。

它是否运行在 Discourse 期望的经典端口号上？

尝试运行 lsof -wni | grep redis

我相信它应该在 6379 端口上。

运行它时，什么也没发生。

natedhaliwal@raspberrypi:~ $ lsof -wni | grep redis
natedhaliwal@raspberrypi:~ $ cd discourse-f
natedhaliwal@raspberrypi:~/discourse-f $ lsof -wni | grep redis
natedhaliwal@raspberrypi:~/discourse-f $
717

它与目录无关。

尝试：

sudo lsof -wni | grep redis

这应该会找回 redis 服务。如果不行，那么您的服务不知何故没有运行，您需要调查原因。

运行此程序后，我仍然收到超时错误。非常奇怪。会不会是我的 ISP 阻止了它？

719

这不是解决方案，而是诊断。该命令的结果是什么？

应该看起来像这样：

robert@raspberrypi:~/discourse $ sudo lsof -wni | grep redis
redis-ser  890    redis    6u  IPv4   4052      0t0  TCP 127.0.0.1:redis (LISTEN)

也试试这个：

robert@raspberrypi:~/discourse $ ps -A | grep redis
    890 ?        00:00:05 redis-server

@merefield 我收到了这个：

natedhaliwal@raspberrypi:~/discourse-f $ sudo lsof -wni | grep redis                          
redis-ser  750        redis    8u  IPv4  16886      0t0  TCP 127.0.0.1:redis (LISTEN)         
natedhaliwal@raspberrypi:~/discourse-f $ ps -A | grep redis                                       
750 ?        00:00:01 redis-server                                                           
9449 ?       00:00:00 redis-server
721

这看起来不对——你有两个 redis 进程在运行？

我建议终止第二个进程。

我猜我应该在 redis-cli 中使用 shutdown 命令，然后重新创建和迁移数据库？
或者使用 client kill？

723

不，只终止第二个进程

kill -9 <进程 ID>

在这种情况下，我认为进程 ID 是 9449。

724

嗯……

-bash: kill: (9449) - Operation not permitted
725

使用 sudo …

为什么您的 discourse 目录叫做 discourse-f？

728

因为已经有一个名为 discourse 的文件夹，其中包含一个 postgres 文件夹，该文件夹显示由于已满而无法克隆。因此，我将其克隆到一个新文件夹中。
我刚刚设法 sudo rm -rf 了那个文件夹（我尝试过 rm -rf 但它显示权限被拒绝，所以我采用了此处的相同策略并使用了 sudo）。
这会影响安装吗？
