overcommit_memory

[carstenlund]

Hi there, I get this warning, and my site stops working.

I'm trying to follow the fix. I have access to my server through ssh, but when I try to access /etc/sysctl.conf Permission is denied.
-bash: /etc/sysctl.conf: Permission denied

I'm not experienced in Redis or SSH, but I can follow simple ssh commands.

How do I access /etc/sysctl.conf to fix the overcommit_memory issue?

Thanks!

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 jemalloc/jemalloc#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.

Hey, these repos are for the Docker image of Redis https://github.com/docker-library/redis
Since this is outside of a container and on the host system, to get permission to modify that file you can use sudo nano /etc/sysctl.conf

I would also try asking over at the Docker Community Forums, Docker Community Slack, or Stack Overflow
