아래 편집자는 MySQL IST 전송만 필요한 새 노드를 구축하는 PXC 방법(권장)에 대한 기사를 가져올 것입니다. 편집자님이 꽤 좋다고 생각하셔서 지금 공유하고 모두에게 참고용으로 드리고자 합니다. 에디터를 따라가서 살펴보겠습니다.
수요 시나리오: 원래 pxc 환경에는 상대적으로 많은 양의 데이터가 있습니다. 대신에 새로 구입한 서버를 이 클러스터에 추가해야 합니다. .
PXC에는 두 가지 데이터 전송 방법이 있습니다.
IST: 증분 상태 전송 증분 동기화
SST: 상태 스냅샷 전체 전송량 동기화
IST 발생 조건: 노드에서 캐싱 메커니즘을 사용하여 수행됩니다(즉, 이전 클러스터에서 발생한 노드 데이터만 여전히 캐시에 남아 있음)
판단 방법:
mysql> show global status like 'wsrep_local_cached_downto';

1 row in set (0.00 sec)

이 값은 새로 열린 노드의 seqno:
[root@zejin241 I6000]# cat grastate.dat
# GALERA saved state
version: 2.1
uuid: 6c86dc17-246f-11e6-9955-ae4d7e89eed2
seqno: 4
cert_index:
로그인 후 복사
보다 작습니다. 그래서 우리의 생각은 클러스터에 있는 노드의 데이터를 백업하고, 새 노드로 복원하고, grastate.dat를 위조하여 백업 데이터의 seqno를 기록함으로써 새 노드가 시작될 때 자동으로 IST 방법을 대신 사용하는 것입니다. SST(백업 및 복구 기간 동안 새로 생성된 데이터가 캐시되도록 하려면 gcache.size에 충분한 용량이 있어야 함)
galera.cache: This file is used as a main writeset store. It's implemented as a permanent ring-buffer file
that is preallocated on disk when the node is initialized. File size can be controlled with the variable
gcache.size. If this value is bigger, more writesets are cached and chances are better that the rejoining node will get IST instead of SST.
Filename can be changed with the gcache.name variable.

[root @zejin241 I6000]# cat xtrabackup_galera_info6c86dc17-246f-11e6-9955-ae4d7e89eed2:8
방법 2: 찾기 by binlog 위치:
[root@zejin241 I6000]# cat xtrabackup_binlog_infolog_bin.000003 2772
즉, 백업 시 백업 지점 위치는 log_bin.000003 2772
이 binlog에 해당하는 xid를 찾기 위해 메인 데이터베이스로 이동합니다
[root@zejin240 I6000]# mysqlbinlog -vv log_bin.000003 | grep Xid#160528 9:02:59 server id 9816000 end_log_pos 947 CRC32 0x37371b3e Xid = 7#160528 10:03:04 서버 ID 981 6000 end_log_pos 2969 CRC32 0xf7973829 Xid = 9#160528 10:03:13 서버 ID 9816000 end_log_pos 3168 CRC32 41 시드 = 10
그랬어요 이 위치에 xid가 없다는 것을 발견했습니다. 그 이유는 상단 mysql.user 테이블에서 를 업데이트했고 이 테이블은 myisam 테이블이므로 Xid 레코드가 설정되지 않기 때문입니다. 위쪽 및 아래쪽 위치에 따라 8개로

데이터 폴더의 모든 파일을 삭제한 다음 SST 공식 지침을 통해 마스터 노드에서 데이터를 가져옵니다.
XtraBackup SST works in two stages: • Stage I on joiner checks if it is SST or IST based on presence of xtrabackup_ist file. • In Stage II it starts the data transfer, if it's SST, it empties the data directory sans few files (galera.cache, sst_in_progress, grastate.dat) and then proceed with the SST or if it's IST, proceeds as before.

이 시점에서 SST가 필요하지 않은 방법을 완료했습니다. pxc 환경에 새 노드가 추가되면 데이터 양이 많을 때 SST는 많은 양의 리소스를 차지합니다. 구성된 gcache.size는 백업 기간 동안 마스터 노드에서 생성되는 데이터 양을 수용하기에 충분합니다. 업무량이 적은 기간 동안 스크립트를 통해 이 새로운 노드를 구현하는 것이 좋습니다.
위 내용은 IST 전송만 필요한 새로운 노드를 구축하는 MySQL PXC의 방법에 대한 자세한 설명의 상세 내용입니다. 자세한 내용은 PHP 중국어 웹사이트의 기타 관련 기사를 참조하세요!
