0x00 NFS准备
在ES集群上做一个NFS,并挂载:
[root@localhost ~]# yum install nfs-utils*
[root@localhost ~]# vi /etc/exports
输入集群的IP地址,例如:
192.168.1.2(rw)
192.168.1.3(rw)
192.168.1.4(rw)
保存退出,并启动NFS服务
[root@localhost ~]# service nfs start
[root@localhost ~]# service rpcgissd start
[root@localhost ~]# service rpcbind start
挂载NFS
[root@localhost ~]# mount elasticsearch.master:/data/es/es_backup /data/es/es_backup
0x01 配置
在elasticsearch.master端执行:
curl -XPUT 'http://elasticsearch.master:9200/_snapshot/backup' -d '{
"type": "fs",
"settings": {
"location": "/data/es/es_backup",
"compress": true
}
}'
备份操作,名字根据自己的情况修改
curl -XPUT http://elasticsearch.master:9200/_snapshot/backup/logstash-2016.01.01 -d '
{"indices":"logstash-sec-2016.01.01",
"ignore_unavailable": "true",
"include_global_state": false }'
0x02 备份常用命令
查看备份状态:
curl –XGET http://elasticsearch.master:9200/_snapshot/backup/logstash-security-2016.01.01
删除备份
curl -XDELETE http://elasticsearch.master:9200/_snapshot/backup/logstash-security-2016.01.01
恢复备份
curl -XPOST http://elasticsearch.master:9200/_snapshot/backup/logstash-security-2016.01.01/_restore -d ' { "indices" : "logstash-security-2016.01.01"}'
0x03 最后附备份脚本
