es报错：doesn’t match any of the locations specified by path.repo
精选 原创今日基于docker 版本的elasticsearch 7.17.3 集群配置备份时发现其配置与老版本有诸多不同，过程中也出现了如标题的报错，特此记录一下。
按照以往版本的es集群配置配置后，设置snapshot时出现如下报错
doesn’t match any of the locations specified by path.repo
根据测试后发现是新的配置发生了变化,如下部分compose文件中es默认工作目录是/usr/share/elasticsearch，配置path.repo时，es会在工作目录中查找path.repo指定的文件夹，若不存在，则会自动创建一个。
version: "3"
services:
elastic:
image: docker.elastic.co/elasticsearch/elasticsearch:7.17.3
volumes:
- /opt/data/apps/backup/es_uat:/usr/share/elasticsearch/backup
environment:
- path.repo=backup
services:
elastic:
image: docker.elastic.co/elasticsearch/elasticsearch:7.17.3
volumes:
- /opt/data/apps/backup/es_uat:/usr/share/elasticsearch/backup
environment:
- path.repo=backup
另snapshot配置中指定的location 则是相对/usr/share/elasticsearch/backup 目录下的文件夹名，若不存在，其也会自动创建
PUT _snapshot/es_backup
{
"type": "fs",
"settings": {
"location": "backup",
"compress": true
}
}
{
"type": "fs",
"settings": {
"location": "backup",
"compress": true
}
}
对于es集群配置备份需要如下步骤
1、在集群中所有节点挂载nfs 到相同路径
2、配置path.repo，注意是相对路径
3、在集群中的所有节点都正常时在kibana中配置snapshot
