安装插件
插件官方文档
一、准备工作
- 一个oss bucket
- 阿里云的
access_key_id,secret_access_key - 一个es5.x的集群
二、安装elasticsearch-repository-oss插件
下载插件
1
| wget https://github.91chi.fun/https://github.com/aliyun/elasticsearch-repository-oss/releases/download/v5.5.3/elasticsearch-repository-oss-5.5.3.zip

| - hosts: es
vars:
plugin_dir: /usr/share/elasticsearch/plugins
plugin_file: ./elasticsearch-repository-oss-5.5.3.zip
tasks:
- name: install aliyun-oss-plugin
unarchive:
src: "{{ plugin_file }}"
dest: "{{ plugin_dir }}"
mode: 0755
- name: alter directory name
shell: "mv {{plugin_dir}}/elasticsearch {{plugin_dir}}/elasticsearch-repository-oss"
# 重启请谨慎
#- name: restart elasticsearch
# service: name=elasticsearch state=restarted

三、创建repositories
repoName: 仓库名称
yourAccesskeyId: 阿里ak
yourAccesskeySecret: 阿里sk
yourBucketName: bucket名称
endpoint: 根据自己bucket的情况修改
base_path: 对应oss中的子路径

| curl -H "Content-Type: application/json" -XPUT localhost:9200/_snapshot/<repoName> -d \
'{
"type": "oss",
"settings": {
"endpoint": "http://oss-cn-hangzhou-internal.aliyuncs.com",
"access_key_id": "<yourAccesskeyId>",
"secret_access_key": "<yourAccesskeySecret>",
"bucket": "<yourBucketName>",
"compress": true,
"base_path": "snapshot/"
}
}'
|
查看仓库 curl http://localhost:9200/_cat/repositories
四、创建snapshot
snapshotName: 快照名

| curl -H "Content-Type: application/json" -XPUT localhost:9200/_snapshot/<repoName>/<snapshotName>?pretty -d'
{
"indices": "index1,index2"
}'
|
如果要备份所有索引执行: curl -XPUT localhost:9200/_snapshot/<repoName>/<snapshotName>
查看快照进度: curl -s http://localhost:9200/_snapshot/<repoName>/_all
恢复快照
一、三种恢复索引的方式
1.恢复所有索引

| curl -XPOST localhost:9200/_snapshot/<repoName>/<snapshotName>/_restore
# 默认后台执行恢复,阻塞执行恢复可以使用
curl -XPOST localhost:9200/_snapshot/<repoName>/<snapshotName>/_restore?wait_for_completion=true
|
2.选择性索引恢复
*代表恢复所有索引
-xxx*代表不恢复哪些索引
1
2
| curl -XPOST localhost:9200/_snapshot/<repoName>/<snapshotName>/_restore
{"indices":"*,-.monitoring*,-.security_audit*","ignore_unavailable":"true"}
|
3.修改索引名恢复
如果集群中已经存在相同索引名的索引,为了不影响现有数据,可以通过如下方式重命名索引。
这里应该也可以在索引恢复过程中,修改索引名称,

6
| curl -XPOST localhost:9200/_snapshot/<repoName>/<snapshotName>/_restore
{
"indices":"index1",
"rename_pattern": "index(.+)",
"rename_replacement": "restored_index_$1"
}
|
indices: 要恢复的索引名称
rename_pattern: 通过正则查找正在恢复的索引
rename_replacement: 重命名查找到的索引
二、查看恢复进度

| # 查看指定索引的恢复状态
curl -XGET localhost:9200/<indexName>/_recovery
# 查看所有索引的恢复状态
curl -XGET localhost:9200/_recovery/
