ElasticSearch单个索引的备份与还原附脚本

操作系统：

[root@host-192-168-213-23 config]# cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core)

1、创建共享仓库

linux下命令行使用时格式改为一行（文档只是利于理解）

curl -i -H ""'Content-Type:application/json;charset=UTF-8'"" -X PUT --data   
     '{
     	 "type": "fs",
    	  "settings":
  		{
  		 "location": "/data/bk/",	#共享仓库的路径，确定ES用户有目录权限
  		 "compress": true
  		}
  	}' http://192.168.199.199:9200/_snapshot/my_backup  #ES的IP地址

修改elasticsearch.yml文件，在文档中添加共享仓库的路径，之后需要重启ES

path.repo: /data/bk

2、备份索引数据

curl -i -H ""'Content-Type:application/json;charset=UTF-8'"" -X PUT --data
    	'{
 	    "indices": "'$name'"	 #需要备份的索引名称
    	}' http://192.168.199.199:9200/_snapshot/my_backup/$name

查看某个索引的备份状态

curl -X GET http://192.168.199.199:9200/_snapshot/my_backup/$name/_status

3、索引还原

还原某个索引数据

curl -i -X POST http://192.168.199.199:9200/_snapshot/my_backup/$name/_restore

5、参考脚本

#创建共享仓库
echo -n "输入要备份的索引名称："
read name
curl -i -H ""'Content-Type:application/json;charset=UTF-8'"" -X PUT --data '{"type": "fs","settings": {"location": "/data/bk/","compress": true}}' http://192.168.199.199:9200/_snapshot/my_backup
#备份索引
curl -i -H ""'Content-Type:application/json;charset=UTF-8'"" -X PUT --data '{"indices": "'$name'"}' http://192.168.199.199:9200/_snapshot/my_backup/$name
#还原索引
curl -i -X POST http://192.168.199.199:9200/_snapshot/my_backup/$name/_restore
