一、問題描述

Redis 之前一直使用正常，某一天突然報錯：

MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

二、解決方法

兩種方法解決：一是通過命令行修改，一是通過配置文件修改。

1.命令行修改

redis-cli
auth XXX
127.0.0.1:6379> config set stop-writes-on-bgsave-error no

2.配置文件修改

修改 redis.conf ，將 stop-writes-on-bgsave-error 設置為 no，然后重啟服務。

三、其它問題

一般還會同時有兩個警告：

WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can 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.

和

WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

警告1解決方法：

echo 1 > /proc/sys/vm/overcommit_memory

警告2解決方法：

vi /etc/sysctl.conf

#添加配置
net.core.somaxconn = 1024

檢查是否成功：sysctl -p
