When deploying redis on the domestic Kirin operating system, the error is as follows:

12707:M 14 Oct 2021 13:55:36.643 # Server initialized
12707:M 14 Oct 2021 13:55:36.643 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the c
ommand 'sysctl vm.overcommit_memory=1' for this to take effect.12707:M 14 Oct 2021 13:55:36.644 # WARNING Your kernel has a bug that could lead to data corruption during background save. Please upgrade to the latest stable kernel.
12707:M 14 Oct 2021 13:55:36.644 # Redis will now exit to prevent data corruption. Note that it is possible to suppress this warning by setting the following config: ignore-warnings ARM64-COW-BUG

Seeing that the Internet says that you need to set the value of overcommit_memory, execute the command as follows (Not tested）：

Because I'm hereThe warning will also be present on the CentOS system, but it will not affect normal boot。

vm.overcommit_memory

The default value is: 0

overcommit_memory Parameter description:

Set memory allocation policy (optional, set according to the actual situation of the server)

/proc/sys/vm/overcommit_memory

Optional values: 0, 1, 2

0: Indicates that the kernel will check if there is enough free memory supply for the process; If there is enough free memory, the memory request allows; Otherwise, the memory request fails and returns an error to the application process.
1: Indicates that the kernel allows all physical memory to be allocated regardless of the current memory state.
2: Indicates that the kernel allows allocating more memory than the sum of all physical memory and swap space


My solution

Run the following command, and then rerun redis:

(End)
