我在我的服务器上安装了 redis 对象缓存，然后使用这个插件来刷新缓存......这对我来说工作了 5 到 6 天......之后。状态未连接操作系统显示....我也在使用 fastcgi 缓存。但是，从 5 天开始，两者都在工作......今天我在重做缓存时遇到了这个错误。错误是：

我找到了答案.. 我的 nginx 服务器上的一些软件已经过时了，为此我运行了一些命令。

sudo apt update

和

sudo apt upgrade

在此之后，您需要编辑 redis 配置文件。在我的情况下，文件位于sudo nano /etc/redis/redis.conf

在这里你必须确认你已经替换#maxmemory为

maxmemory 128mb
maxmemory-policy allkeys-lfu

然后使用重新启动redis和php

sudo service redis-server restart
sudo service php7.2-fpm restart

然后使用下面给出的代码进行测试：

redis-cli
ping
set test "It's working"
get test

这将显示结果"it's working"

现在使用命令exit退出

恭喜，问题解决
