Redis trouble07 -- MISCONF redis save RDB snapshots, but is currently not able to persist

一、问题描述

线上每隔一天redis就会报出来下边的问题

MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist

二、解决方案

归根到底就是redis持久化失败:提供下边的配置解决

Redis服务端参数:
config set stop-writes-on-bgsave-error no
config rewrite

系统参数:
sysctl vm.overcommit_memory=1 临时生效,重启服务器配置会失效
vim /etc/sysctl.conf
    vm.overcommit_memory = 1  将此配置同时添加在配置文件中,重启会加载
