redis - Linux Container 中 redis.conf 中 IP 的绑定地址

问题描述

在 Ubuntu 20.04 中，我创建了一个名为“ubuntuone”的 Linux 容器，以及 Ubuntu 20.04。

在 Linux 容器中，我安装了 Redis，但我得到了 Could not connect to Redis at 127.0.0.1:6379

(base) raphy@pc:~$ lxc exec ubuntuone -- /bin/bash
root@ubuntuone:~# redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected>

这是ifconfiglinux 容器中的输出：

(base) raphy@pc:~$ lxc exec ubuntuone -- /bin/bash
root@ubuntuone:~# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.65.116.195  netmask 255.255.255.0  broadcast 10.65.116.255

        TX packets 8  bytes 496 (496.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

我也尝试设置/etc/redis/redis.conf：

bind 10.65.116.195 ::1

但我得到同样的错误

更新 1)

redis-server 已安装，但 redis-service.service 守护进程有一些问题：

解决方案

阅读您的评论后，似乎 Redis 服务仅已安装未启动。您可以使用redis-server二进制文件启动它。启动后，您将能够连接。

此外，您不需要在 Ubuntu 容器内安装 redis 服务器。在 Debian 或其他 SO 上已经有预先构建的 redis 映像。请检查Redis Docker Hub
