echo 511 > /proc/sys/net/core/somaxconn

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 command ‘sysctl vm.overcommit_memory=1’ for this to take effect.

在 /etc/sysctl.conf 目录下新增以下代码

vm.overcommit_memory = 1

WARNING: you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix thisissue run the command ‘echo never > /sys/kernel/mm/transparent_hugepage/enabled’ as root, and add it to your /etc/rc.local in order to retain thesetting after a reboot. Redis must be restarted after THP is disabled.

在 /etc/rc.local 目录下新增以下代码

echo never > /sys/kernel/mm/transparent_hugepage/enabled
