}安装 NFS 服务器所需的软件包
[root@wyl01 opt]# yum install -y nfs-utils
编辑exports文件，添加从机器
[root@wyl01 opt]# vim /etc/exports
/usr/local/esbackup 192.168.52.129(rw,sync,fsid=0) 192.168.52.130(rw,sync,fsid=0)注意：
129，130两台机器可以挂载NFS服务器上的/data目录到自己的文件系统中
rw表示可读写；sync表示同步写
启动nfs服务
systemctl enable rpcbind.service
systemctl enable nfs-server.service
systemctl start rpcbind.service
systemctl start nfs-server.service确认NFS服务器启动成功
[root@wyl01 elasticsearch-7.3.0]# rpcinfo -p|grep nfs
100003 3 tcp 2049 nfs
100003 4 tcp 2049 nfs
100227 3 tcp 2049 nfs_acl
100003 3 udp 2049 nfs
100003 4 udp 2049 nfs
100227 3 udp 2049 nfs_acl
检查 NFS 服务器是否挂载我们想共享的目录 /usr/local/esbackup
[root@wyl01 usr]# exportfs
/usr/local/esbackup
192.168.52.129
/usr/local/esbackup
192.168.52.130
在从机上安装NFS 客户端
首先是安裝nfs，同上，然后启动rpcbind服务
#rpcbind做开机启动
systemctl enable rpcbind.service
#启动rpcbind服务
systemctl start rpcbind.service注意：客户端不需要启动nfs服务
在从机上使用 mount 挂载服务器端的目录/usr/local/esbackup到客户端的/usr/local/esbackup目录下
[root@wyl02 opt]# mkdir -p /usr/local/esbackup
[root@wyl02 opt]# mount -t nfs 192.168.52.128:/usr/local/esbackup /usr/local/esbackup
[root@wyl03 opt]# mkdir -p /usr/local/esbackup
[root@wyl03 opt]# mount -t nfs 192.168.52.128:/usr/local/esbackup /usr/local/esbackup
开始创建仓库
[root@wyl01 elasticsearch-7.3.0]# curl -XPUT 'http://192.168.52.128:9200/_snapshot/my_backup' -H 'Content-Type: application/json' -d '{
> "type": "fs",
> "settings": {"compress" : "true",
> "location": "/usr/local/esbackup"
> }
> }'
{"acknowledged":true}查看仓库。
其实如果返回下面的值，表示建立成功
[root@wyl01 elasticsearch-7.3.0]# curl -XGET 'http://192.168.52.128:9200/_snapshot?pretty'
{
"my_backup" : {
"type" : "fs",
"settings" : {
"compress" : "true",
"location" : "/usr/local/esbackup"
}
}
}
{"acknowledged":true}备份索引
[root@wyl01 opt]# curl -XPUT 'http://192.168.52.128:9200/_snapshot/my_backup/snapshot_1'
{"accepted":true}我们查看一下备份数据吧，查看的命令如下
[root@wyl01 elasticsearch-7.3.0]# curl -XGET 'http://192.168.52.128:9200/_snapshot/my_backup/snapshot_1'
{
"snapshots":[
{
"snapshot":"snapshot_1",
"uuid":"7yRvCNeVRNWEm-Gm4cIBEQ",
"version_id":7030099,
"version":"7.3.0",
"indices":[
"people",
"student"
],
"include_global_state":true,
"state":"SUCCESS",
"start_time":"2019-09-02T07:22:36.931Z",
"start_time_in_millis":1567408956931,
"end_time":"2019-09-02T07:22:37.458Z",
"end_time_in_millis":1567408957458,
"duration_in_millis":527,
"failures":[
],
"shards":{
"total":2,
"failed":0,
"successful":2
}
}
]
}迁入地集群也需要配置elasticsearch.yml文件，增加path.repo的配置。
目标ES集群中创建repository
[root@lhf01 elasticsearch-7.3.0]# curl -XGET 'http://192.168.12.11:9200/_snapshot?pretty'
{
"my_backup" : {
"type" : "fs",
"settings" : {
"compress" : "true",
"location" : "/usr/local/esbackup"
}
}
}
{"acknowledged":true}将源es的快照文件拷贝到目标es的esbackup目录下，然后就可以从中读出信息
[root@lhf01 elasticsearch-7.3.0]# curl -XGET 192.168.12.11:9200/_snapshot/my_backup/_all
{
"snapshots":[
{
"snapshot":"snapshot_1",
"uuid":"7yRvCNeVRNWEm-Gm4cIBEQ",
"version_id":7030099,
"version":"7.3.0",
"indices":[
# 可以看到2个索引
"people",
"student"
],
"include_global_state":true,
"state":"SUCCESS",
"start_time":"2019-09-02T07:22:36.931Z",
"start_time_in_millis":1567408956931,
"end_time":"2019-09-02T07:22:37.458Z",
"end_time_in_millis":1567408957458,
"duration_in_millis":527,
"failures":[
],
"shards":{
"total":2,
"failed":0,
"successful":2
}
}
]
}备份数据迁移
[root@lhf01 elasticsearch-7.3.0]# curl -XPOST 'http://192.168.12.11.13:9200/_snapshot/my_backup/snapshot_1/_restore'
