es备份数据及恢复

在备份之前要在es/config/elasticsearch.yml添加仓库配置，并重启es

path.repo: [“/usr/share/elasticsearch/backup”]

在/usr/share/elasticsearch/backup下新建名为bro_backup的仓库

curl -u admin:admin -XPOST '127.0.0.1:9200/_snapshot/bro_backup' -H  'Content-Type: application/json' -d '{ "type": "fs",  "settings": { "location": "/usr/share/elasticsearch/backup", "compress": true, "chunk_size": "1g", "max_snapshot_bytes_per_sec": "50m", "max_restore_bytes_per_sec": "50m"}}'

max_snapshot_bytes_per_sec 和max_restore_bytes_per_sec 为了限制备份和恢复时的速度

备份数据

1	curl -u admin:admin -XPUT "127.0.0.1:9200/_snapshot/bro_backup/es_20220809?wait_for_completion=true"

查看备份信息

1	curl -u admin:admin -XGET http://127.0.0.1:9200/_snapshot/bro_backup/es_20220809

5.执行恢复命令，新节点的es 需要执行 1-2 步骤

1	curl -XPOST '127.0.0.1:9200/_snapshot/bro_backup/es_20220809/_restore' -H 'Content-Type: application/json' -d'{ "ignore_unavailable": true, "include_global_state": false }'

6.查看恢复的数据

1	curl -u admin:admin '127.0.0.1:9200/_cat/indices?v'

设置 max_shards_per_node 分片

1	curl -X PUT "localhost:9200/_cluster/settings?pretty" -H 'Content-Type: application/json' -d '{"persistent" : {"cluster" : {"max_shards_per_node" : "5000"}}}'

ik 分词测试

1	curl --user elastic:zj2018 -H "Content-Type: application/json" -XPOST http://127.0.0.1:9200/_analyze -d'{"analyzer":"ik_max_word","text":"日子啊啊啊啊啊啊"}'
