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. ...
执行sysctl -p命令来应用更改: 运行以下命令以使新的sysctl设置立即生效: bash sudo sysctl -p 完成这些步骤后,你的Docker宿主机已经应用了vm.overcommit_memory = 1这个配置,这应该会解决Redis启动时遇到的内存分配警告问题。如果问题仍然存在,可能需要进一步检查Redis的配置或日志来诊断问题。

如果被禁用,它也可能在没有内存不足的情况下导致故障,请参阅https:///jemalloc/jemalloc/issues/1328.若要解决此问题,请将“vm.overcommit_memory=1”添加到/etc/sysctl.conf,然后重新启动或运行命令“sysctl vm.overommit_memory=1”以使其生效。 redis给出了解决方案,就是在/etc目录下的sysctl.conf文件中添加...
使用Docker run 命令部署 Redis 的完整指南 Redis 作为当今最流行的内存数据库和缓存解决方案之一,与 Docker 容器技术的结合为开发者提供了极致的部署灵活性和环境一致性。 一、Redis 容器化概述 1.1 容器化部署优势 Redis 容器化部署具有以下显著优势: 秒级启动:传统安装需要编译和配置,容器化部署仅需一条命令 ...

2.redis 调优 考虑到redis一般都是部署在服务器上作为服务存在的。所以,本文的解决方案都是持久性配置,不是临时配置。 第一个警告 将net.core.somaxconn = 1024添加到/etc/sysctl.conf中,然后执行sysctl -p生效配置。 第二个警告 将vm.overcommit_memory = 1添加到/etc/sysctl.conf中,然后执行sysctl -p生效配...
