배경:
일치하지 않는 링 버퍼 설정을 가진 대용량 캐싱 네임 서버 환경 (Redhat Enterprise Linux 5.8, IBM System x3550)을 상속했습니다 : eth0의 경우 1020, eth1의 경우 255입니다. eth0은 로컬 데이터 센터의 스위치 1에 연결되고 eth1은 같은 스위치 2에 연결됩니다. 클러스터의 모든 서버는 eth0 또는 eth1이 활성 인터페이스인지 여부와 모든 클러스터가 다른 지역에 있는지 여부를 번갈아 표시합니다. 링 버퍼는 분명히 일관성을 유지해야합니다.
상황이 까다을받을 곳은 다음과 같습니다 나는 네임 서버의 숫자가 자주 로그인하는 이유를 연구 할 때 위의 문제 발견 "오류 보내는 응답 : 해제"오류, ISC 회사의 지식이 제안은 아웃 바운드 혼잡 관련이있다 . 더 높은 링 버퍼 설정 (1020)을 가진 서버는 ifconfig에서 더 적은 수의 패킷을 삭제하지만 예상 한대로 가장 높은로드 그룹 중 하나에서 하루 ~ 20k 회 높은 빈도로 위의 오류를 기록하는 경향이 있습니다. 이것을``그룹 1 ''이라고 부릅니다. 낮은 링 버퍼 (255) 설정을 가진 서버는 하루에 훨씬 더 많은 인바운드 패킷을 삭제하지만 (예상), 동일한로드 그룹에서 BIND 오류 인스턴스가 훨씬 적습니다 (일반적으로 0-150).
여기서도 큰 비밀이 아닙니다. 캐싱 DNS는 재귀 서비스입니다. 캐시되지 않은 경우 서버는 최종적으로 답변을 반환 할 수있을 때까지 해당 질문 대신 여러 개의 쿼리를 작성해야합니다. (1 in)-> (many out) 쿼리 관계입니다. RX 링 버퍼를 수정하면이 숫자가 보드 전체에서 새로운 값과 같아 지므로 proc (wmem_max / wmem_default)에서 커널의 아웃 바운드 네트워크 큐를 조정하는 것이 좋습니다.
성능 변경에 대한 구성 변경의 영향을 측정 할 수 있으므로 생산 변경을 시작하기 전에 일부 데이터를 수집하는 보고서를 작성했습니다. 다음은 그룹 1의 처음 두 서버에 대한 출력 예입니다.
group1-01
RX: 7166.27/sec av.
TX: 7432.57/sec av.
RXDROP: 7.43/sec av.
unset_err: 27633
group1-02
RX: 7137.37/sec av.
TX: 7398.50/sec av.
RXDROP: 9.94/sec av.
unset_err: 107
이들은 공식입니다. 이것은 로컬 스크립트이며 서버별로 유지 관리해야하는 쉘 스크립트에 의존하지 않습니다.
RXPACK=$(ssh $server "sar -n DEV -f /var/log/sa/sa$(date --date=yesterday '+%d') | grep \"Average: .*\$(awk '{if (\$2 == "00000000") { print \$1 }}' /proc/net/route)\" | awk '{print \$3}'" 2>/dev/null)
TXPACK=$(ssh $server "sar -n DEV -f /var/log/sa/sa$(date --date=yesterday '+%d') | grep \"Average: .*\$(awk '{if (\$2 == "00000000") { print \$1 }}' /proc/net/route)\" | awk '{print \$4}'" 2>/dev/null)
RXDROP=$(ssh $server "sar -n EDEV -f /var/log/sa/sa$(date --date=yesterday '+%d') | grep \"Average: .*\$(awk '{if (\$2 == "00000000") { print \$1 }}' /proc/net/route)\" | awk '{print \$6}'" 2>/dev/null)
TXDROP=$(ssh $server "sudo grep 'error sending response: unset' /var/log/dns_named.1" 2>/dev/null | wc -l)
모든 캐싱 DNS 환경에서이 보고서를 실행하기 시작하면 거의 동일한 패킷로드를 가진 다른 그룹 (그룹 2라고 함) 에 아무런 문제가 없음을 알 수 있습니다 .
group2-01
RX: 7066.44/sec av.
TX: 7345.95/sec av.
RXDROP: 0.00/sec av.
unset_err: 0
group2-02
RX: 7019.18/sec av.
TX: 7312.47/sec av.
RXDROP: 0.00/sec av.
unset_err: 0
질문:
RX 링 버퍼 또는 net.core.wmem_default
/를 추가로 조정하지 않고 group2가 왜 이런 식으로 동작 net.core.wmem_max
합니까? 링 버퍼를 무엇이든 상관없이 정규화해야하지만 / proc에서 wmem 값으로 재생하기 전에 여기에서 무엇이 진행되고 있는지 이해하고 싶습니다.
내가 생각할 수있는 유일한 것은 응용 프로그램에서 대기열이 더 빨리 비워진다는 것입니다.하지만 네트워크 스택 조정은 실습 경험이 많지 않으며 두 번째 의견을 얻고 싶습니다. (일부 ethtool 카운터 이름에서 눈이 번쩍입니다. 거부하지 않습니다)
가능성으로 다음을 제거했습니다. 분배기 뒤의 증거가 이어집니다.
- 링 버퍼 레이아웃은 동일합니다. (group1과 group2의 첫 번째 서버는 동일하게 구성, group1과 group2의 두 번째 서버는 동일하게 구성)
- 기본 게이트웨이 레이아웃은 동일합니다.
- 네트워크 카드는 동일합니다. (Broadcom BCM5708)
- ethtool에 의해보고 된 펌웨어 버전은 동일합니다. (bc 4.0.3 ipms 1.6.0)
sysctl -a
두 그룹의 첫 번째 서버와 두 그룹의 두 번째 서버간에 출력이 일치합니다. (커널 및 fs 섹션 제외)- 그룹 1과 그룹 2의 총 서버 수는 동일합니다. (10)
기밀 유지를 위해 raw named.conf 또는 정보를 제외하기 위해 사용중인 grep 필터를 표시 할 수 없습니다. 다음과 같은 구성 매개 변수가 네 서버 모두에서 일정하다는 사실을 알아야합니다.
notify no;
allow-transfer { none; };
allow-recursion { any; };
allow-query { any; };
allow-query-cache { any; };
recursive-clients 100000;
max-cache-size 2G;
max-ncache-ttl 900;
다음은 많은 시스템 정보입니다. "hosthash"는 루프의 각 반복이 실제로 실제 호스트 이름을 나타내지 않고 다른 서버에 충돌하고 있음을 보여주기위한 것입니다.
호스트 해시 :
group1-1: dc78abcb154b74c87feecb3f35222263d40c028c
group1-2: 9fe491d58fd1e7d4e21e5bf10c164e4cf66e884b
