amazon-web-services - 无法启动 Redis 内存数据存储。 Ubuntu 18.04

Question

我正在尝试在我的 AWS 服务器上安装 redis。我在上面安装了 Ubuntu 18.04。我正在按照步骤从 digitalocean 安装 redis文章。

当我运行 sudo systemctl status redis 命令时，出现以下错误。

我尝试编辑 /etc/systemd/system/redis.service 文件并在 [Service] 部分下添加了 Type=forking 但是仍然出现相同的错误。

谁能建议我如何修复它？

提前致谢。

基于相同的 digitalocean 教程，实际上它运行良好。

运行此命令sudo systemctl restart redis.service，我们得到(在最后一行显示“失败”):

但是如果你运行 sudo service redis-server status，我们会得到(在第 3 行显示“running”):

找了好几个小时，好像systemctl 和 service 有什么区别而已，但实际的redis服务器运行正常。如果不是这样，请纠正我。这是链接:https://askubuntu.com/questions/903354/difference-between-systemctl-and-service-commands

你甚至可以通过redis-cli ping检查redis是否工作正常，应该打印PONG
