ELK数据迁移,ES快照备份迁移

　　通过curl命令或者kibana快照备份，恢复的方式进行数据迁移

环境介绍

　　之前创建的ELK 因为VPC环境的问题，需要对ELK从新部署，但是还需要保留现有的数据，于是便有了这篇文档。

10.0.20.74 old es

10.0.10.229 new es

方法一、命令行操作

一、创建快照存储库

1.修改老的es配置文件，用于快照存储库。

[root@elk-server /home]# cat /etc/elasticsearch/elasticsearch.yml |grep  path.repo
path.repo: /home/esdata  

如果你也是集群模式的话 必须要创建并挂载共享目录

2、分配权限并重启es

[root@elk-server /home]# chown -R elasticsearch:elasticsearch  esdata
[root@elk-server /home]# systemctl  restart elaseicesarch
[root@elk-server /home]# ll |grep esdata
drwxr-xr-x  3 elasticsearch elasticsearch        134 Jun  8 08:13 esdata

3、创建ES本地存储库

curl -XPUT -uxuewenlong:bsh@123  http://10.0.20.74:9200/_snapshot/my_back -H "Content-Type: application/json"  -d '
{
          "type": "fs",
          "settings": {
              "location": "/home/esdata/",   #存储库位置，要和配置文件里一致用户组是es
              "max_restore_bytes_per_sec":"10mb",          #恢复最大速率
              "compress":"true",                           #是否压缩
              "max_snapshot_bytes_per_sec":"10mb",         #创建最大速率
              "chunk_size":"100mb"                          #压缩块大小
          }
      }'

4、验证存储库

curl -XGET -uxuewenlong:bsh@123 http://10.0.20.74:9200/_snapshot/
{
    "my_back": {
        "type": "fs",
        "settings": {
            "chunk_size": "100M",
            "location": "/home/esdata/",
            "max_restore_bytes_per_sec": "10mb",
            "compress": "true",
            "max_snapshot_bytes_per_sec": "10mb"
        }
    }
}

二、备份索引

1、备份指定的索引

curl -XPUT -uxuewenlong:bsh@123 http://10.0.20.74:9200/_snapshot/my_back/esdata?wait_for_completion=true -H "Content-Type: application/json"  -d '
   {
 "indices": "miniprogram-prod*"   #写入需要备份的索引,多个所以以,分隔 如"index1,index2" 支持正则
   }'

2、备份当前库所有索引

curl -XPUT -uxuewenlong:bsh@123 http://10.0.20.74:9200/_snapshot/my_back/esdata?wait_for_completion=true -H "Content-Type: application/json"

3、验证备份快照

curl -XGET -uxuewenlong:bsh@123 http://10.0.20.74:9200/_snapshot/my_back/esdata
{
    "snapshots": [{
        "snapshot": "esdata",
        "uuid": "t3BNDuiCRwK_uAIz71RCbQ",
        "version_id": 7050099,
        "version": "7.5.0",
        "indices": ["miniprogram-prod-aspect-az.log.2020.01", "miniprogram-prod-aspect-az.log.2020.03", "miniprogram-prod-aspect-az.log.2020.06", "miniprogram-prod-access-az.log.2019.12", "miniprogram-prod-aspect-az.log.2020.02", "miniprogram-prod-aspect-bz.log.2020.02", "miniprogram-prod-access-az.log.2020.06", "miniprogram-prod-aspect-az.log.2020.05", "miniprogram-prod-aspect-az.log.2020.04", "miniprogram-prod-access-az.log.2020.04", "miniprogram-prod-access-az.log.2020.03", "miniprogram-prod-aspect-bz.log.2020.05", "miniprogram-prod-access-az.log.2020.01", "miniprogram-prod-access-az.log.2020.05", "miniprogram-prod-access-bz.log.2020.03", "miniprogram-prod-aspect-bz.log.2020.04", "miniprogram-prod-access-bz.log.2020.06", "miniprogram-prod-aspect-bz.log.2020.03", "miniprogram-prod-access-bz.log.2020.02", "miniprogram-prod-access-az.log.2020.02", "miniprogram-prod-aspect-bz.log.2020.01", "miniprogram-prod-access-bz.log.2020.01", "miniprogram-prod-access-bz.log.2020.05", "miniprogram-prod-access-bz.log.2020.04", "miniprogram-prod-aspect-bz.log.2020.06"],
        "include_global_state": true,
        "metadata": {
            "policy": "miniesdata"
        },
        "state": "SUCCESS",
        "start_time": "2020-06-08T07:48:00.006Z",
        "start_time_in_millis": 1591602480006,
        "end_time": "2020-06-08T08:01:57.507Z",
        "end_time_in_millis": 1591603317507,
        "duration_in_millis": 837501,
        "failures": [],
        "shards": {
            "total": 25,
            "failed": 0,
            "successful": 25
        }
    }]
}

三、迁移到新的es集群中

[root@elk-server /home]# zip -r esdata.zip  esdata
[root@elk-server /home]# scp /home/esdata.zip xuewenlong@10.0.10.229:/home

1、登录新es集群操作

解压es数据，分配权限

[root@ip-10-0-10-229 home]# unzip  esdata.zip
[root@ip-10-0-10-229 home]# ll
drwxr-xr-x. 9 root          root          115 Jun  9 00:58 bsh
drwx------. 3 ec2-user      ec2-user      113 Jun  8 08:25 ec2-user
drwxr-xr-x. 3 xuewenlong    xuewenlong    134 Jun  9 01:31 esdata
[root@ip-10-0-10-229 home]#chown  -R elasticsearch:elasticsearch esdata

2、修改es配置文件

[root@ip-10-0-10-229 home]# cat /etc/elasticsearch/elasticsearch.yml |grep  path.repo
path.repo: /home/esdata

3、创建一样的存储库

**路径以及权限一定要一样

curl -XPUT -uxuewenlong:bsh@123  http://10.0.10.229:9200/_snapshot/my_back -H "Content-Type: application/json"  -d '
{
          "type": "fs",
          "settings": {
              "location": "/home/esdata/",   #存储库位置，要和配置文件里一致用户组是es
              "max_restore_bytes_per_sec":"10mb",          #恢复最大速率
              "compress":"true",                           #是否压缩
              "max_snapshot_bytes_per_sec":"10mb",         #创建最大速率
              "chunk_size":"100mb"                          #压缩块大小
          }
      }'

4、验证备份是否存在

curl -XGET -uelastic:bsh@123 http://10.0.10.229:9200/_snapshot/my_back/esdata
    "snapshots": [{
        "snapshot": "esdata",
        "uuid": "t3BNDuiCRwK_uAIz71RCbQ",
        "version_id": 7050099,
        "version": "7.5.0",
        "indices": ["miniprogram-prod-aspect-az.log.2020.01", "miniprogram-prod-aspect-az.log.2020.03", "miniprogram-prod-aspect-az.log.2020.06", "miniprogram-prod-access-az.log.2019.12", "miniprogram-prod-aspect-az.log.2020.02", "miniprogram-prod-aspect-bz.log.2020.02", "miniprogram-prod-access-az.log.2020.06", "miniprogram-prod-aspect-az.log.2020.05", "miniprogram-prod-aspect-az.log.2020.04", "miniprogram-prod-access-az.log.2020.04", "miniprogram-prod-access-az.log.2020.03", "miniprogram-prod-aspect-bz.log.2020.05", "miniprogram-prod-access-az.log.2020.01", "miniprogram-prod-access-az.log.2020.05", "miniprogram-prod-access-bz.log.2020.03", "miniprogram-prod-aspect-bz.log.2020.04", "miniprogram-prod-access-bz.log.2020.06", "miniprogram-prod-aspect-bz.log.2020.03", "miniprogram-prod-access-bz.log.2020.02", "miniprogram-prod-access-az.log.2020.02", "miniprogram-prod-aspect-bz.log.2020.01", "miniprogram-prod-access-bz.log.2020.01", "miniprogram-prod-access-bz.log.2020.05", "miniprogram-prod-access-bz.log.2020.04", "miniprogram-prod-aspect-bz.log.2020.06"],
        "include_global_state": true,
        "metadata": {
            "policy": "miniesdata"
        },
        "state": "SUCCESS",
        "start_time": "2020-06-08T07:48:00.006Z",
        "start_time_in_millis": 1591602480006,
        "end_time": "2020-06-08T08:01:57.507Z",
        "end_time_in_millis": 1591603317507,
        "duration_in_millis": 837501,
        "failures": [],
        "shards": {
            "total": 25,
            "failed": 0,
            "successful": 25
        }
    }]
}

四.数据恢复到新集群中

1、恢复单条索引

curl -XPOST -uxuewenlong:bsh@123 http://10.0.10.229:9200/_snapshot/my_back/esdata/_restore -H "Content-Type: application/json" -d '
   {
 "miniprogram-prod*"
   }'

2、恢复全部索引

curl -XPOST -uxuewenlong:bsh@123 http://10.0.10.229:9200/_snapshot/my_back/esdata/_restore -H "Content-Type: application/json"

3、删除快照

curl -XDELETE -uxuewenlong:bsh@123  -uxuewenlong:bsh@123 http://10.0.10.229:9200/_snapshot/my_back/esdata/

方法二、kibana操作

1.修改老的es配置文件，用于快照存储库。

[root@elk-server /home]# cat /etc/elasticsearch/elasticsearch.yml |grep  path.repo
path.repo: /home/esdata 

一、创建快照存储库

1、在旧的kibana上创建快照存储库

2、在旧的kibana验证存储库

二、创建策略备份索引

1、在旧的kibana创建策略

支持cron定时任务 还是比较方便的

 

 

 

2、在旧的kibana进行数据备份

保存完策略之后点击小按钮就会立马进行备份

3、在旧的kibana备份完查看备份

三、迁移到新的es集群中

1、登陆服务器old es 服务器讲备份数据打包 移至新的es服务器

[root@elk-server /home]# zip -r esdata.zip  esdata
[root@elk-server /home]# scp /home/esdata.zip xuewenlong@10.0.10.229:/home

2、登录新es集群操作解压es数据，分配权限

[root@ip-10-0-10-229 home]# unzip  esdata.zip
[root@ip-10-0-10-229 home]# ll
drwxr-xr-x. 9 root          root          115 Jun  9 00:58 bsh
drwx------. 3 ec2-user      ec2-user      113 Jun  8 08:25 ec2-user
drwxr-xr-x. 3 xuewenlong    xuewenlong    134 Jun  9 01:31 esdata
[root@ip-10-0-10-229 home]#chown  -R elasticsearch:elasticsearch esdata

3、在新的kibana创建存储库

4、在新的kibana刷新浏览器 查看恢复快照

 

 

 

5、在新的kibana查看恢复状态

 

 

四、验证es数据

在新的kibana 上创建索引，数据是存在的

至此es数据迁移成功
