eredis: Re-establishing connection to "10.3.8.209":6379 due to {connection_error, econnrefused}

这个错误提示说明 eredis 在连接 Redis 时出现了连接被拒绝的错误,可能是由于 Redis 服务没有启动或者 Redis 服务的地址和端口号被配置错误等原因导致的。
如果你确定 Redis 服务已经启动并且地址和端口号配置正确,那么可以尝试增加一些重连的选项来解决这个问题。以下是一个示例代码:
```erlang
% 创建 Redis 连接选项
Opts = [{host, "10.3.8.209"}, {port, 6379}, {reconnect, true}, {reconnect_interval, 5000}].
% 连接 Redis
{ok, Conn} = eredis:start_link(Opts).
% 执行 Redis 命令
{ok, <<"OK">>} = eredis:q(Conn, ["SET", "mykey", "myvalue"]).
```
在上面的示例中,我们增加了两个选项 `{reconnect, true}` 和 `{reconnect_interval, 5000}`。前者表示在连接断开时自动重连,后者表示重连间隔为 5 秒。这样可以在 Redis 服务重新启动后自动重连,避免了手动重启 eredis 的过程。
如果还是无法解决问题,可以检查 Redis 服务的日志,查看是否有其他的错误提示。如果需要进一步调试,可以尝试使用 Redis 的命令行工具 `redis-cli` 进行连接和操作,看看是否能够正常连接和执行操作。
