2. 메모리 설정

Redis 구동시 TCP Backlog 경고시

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.

메모리 사용이 허용량을 넘아가게 될 경우에 대한 처리

sysctl vm.overcommit_memory=1  
echo "vm.overcommit_memory=1" >> /etc/sysctl.conf

3.TCP Backlog

Redis 구동시 TCP Backlog 경고시

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

somaxconn은 ‘Socket Max Connection’의 약어로 최대 연결 개수를 뜻합니다. 리눅스의 경우 메모리가 128MB 보다 작을 경우 128이 기본이고, 클 경우 1024가 기본입니다.
동시에 너무 많은 요청이 올 경우, 예를 들어, somaxconn 값이 128일 경우 그 이상 요청이 오는 것에 대해서는 연결을 거부하게 됩니다.

sysctl -w net.core.somaxconn=65535
echo "net.core.somaxconn=65535" >> /etc/sysctl.conf 

4. THP

Redis 구동시 TCP Backlog 경고시

WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue 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 the setting after a reboot. Redis must be restarted after THP is disabled.

Transparent Hug Pages (THP)는 대량의 메모리를 관리하기 위한 한 방법으로, 페이지 크기를 확대(2MB or 1GB)하여 사용하는 방법입니다. THP는 성능 개선을 목적으로하며,
대부분의 시스템 설정의 성능을 향상시키지만 DB와 같은 특정 상황에 대해서는 오히려 성능이 악화될 수 있습니다.

Redis는 실행 시 THP가 enabled 되어 있는 경우 경고 메시지를 출력하며, 해당 기능을 끄도록 제안하고 있습니다.
참조 : http://allthatlinux.com/dokuwiki/doku.php?id=thp_transparent_huge_pages_%EA%B8%B0%EB%8A%A5%EA%B3%BC_%EC%84%A4%EC%A0%95_%EB%B0%A9%EB%B2%95

  • Transparent Hug Pages 확인
cat /sys/kernel/mm/transparent_hugepage/enabled 
always [madvise] never

해당 기능은 아래와 같은 명령을 수행하는 것으로 끌 수 있습니다.

echo never | sudo tee /sys/kernel/mm/transparent_hugepage/enabled
echo never | sudo tee /sys/kernel/mm/transparent_hugepage/defrag

시작시 마다 해당 명령이 수행되도록 하기 위해 /etc/rc.local 파일에 명령을 추가

sudo sed -i -e '$i \echo never > /sys/kernel/mm/transparent_hugepage/enabled' /etc/rc.d/rc.local
sudo sed -i -e '$i \echo never > /sys/kernel/mm/transparent_hugepage/defrag\n' /etc/rc.d/rc.local
