前置工作索引备份

    1.索引备份

    1. #创建Es备份仓库es_bk文件夹
    2. cd /iflytek/data
    3. mkdir es_bk
    4. #给es用户添加访问权限
    5. chown -R elastic:elastic /iflytek/data/es_bk/
    7. cd /iflytek/server/elasticsearch-5.4.3
    8. #配置es配置
    9. vim config/elasticsearch.yml
    11. #添加一下数据行 配置以上创建的文件夹
    12. path.repo: ["/iflytek/data/es_bk"]
    14. #重启ES  确认用户是否为elastic
    15. kill -9 espid
    17. su elastic
    18. cd /iflytek/server/elasticsearch-5.4.3/bin
    19. ./elasticsearch -d

    2.新建索引备份仓库

    1. #新建备份仓库
    2. PUT _snapshot/my_backup
    3. {
    4.   "type": "fs",
    5.   "settings": {
    6.     "location": "/iflytek/data/es_bk",
    7.     "compress": true
    8.   }
    9. }
    10. #查看备份仓库
    11. GET _snapshot/my_backup
    12. #备份索引tuling-swk-sw 为索引名称 my_backup为仓库名称
    14. PUT _snapshot/my_backup/snapshot_swk?wait_for_completion=true
    15. {
    16.   "indices": "tuling-swk-sw",
    17.   "ignore_unavailable": true,
    18.   "include_global_state": false
    19. }
    21. #恢复数据
    22. POST /_snapshot/my_backup/snapshot_swk/_restore
    23. {
    24.   "indices": "tuling-swk-sw",
    25.   "rename_pattern": "index_(.+)",
    26.   "rename_replacement": "restored_index_$1"
    27. }

    3.删除语句（非必要不执行）

    1. #以下删除语句不要执行
    2. #删除备份
    3. DELETE _snapshot/my_backup/snapshot_swk
    4. #删除仓库
    5. DELETE _snapshot/my_backup
    6. #查看所有
    7. GET _snapshot/my_backup/_all

    附(curl执行语句)

    1. #创建仓库
    2. curl -XPUT "http://10.124.41.11:9209/_snapshot/my_backup" -H 'Content-Type: application/json' -d'
    3. {
    4.   "type": "fs",
    5.   "settings": {
    6.     "location": "/iflytek/data/es_bk",
    7.     "compress": true
    8.   }
    9. }'
    11. #查看仓库
    12. curl -XGET "http://10.124.41.11:9209/_snapshot/my_backup"
    14. #备份索引
    15. curl -XPUT "http://10.124.41.11:9209/_snapshot/my_backup/snapshot_swk?wait_for_completion=true" -H 'Content-Type: application/json' -d'
    16. {
    17.   "indices": "tuling-swk-sw",
    18.   "ignore_unavailable": true,
    19.   "include_global_state": false
    20. }'
    22. #恢复索引数据
    23. curl -XPOST "http://10.124.41.11:9209/_snapshot/my_backup/snapshot_swk/_restore" -H 'Content-Type: application/json' -d'
    24. {
    25.   "indices": "tuling-swk-sw",
    26.   "rename_pattern": "index_(.+)",
    27.   "rename_replacement": "restored_index_$1"
    28. }'
    32. curl -XDELETE "http://10.124.41.11:9209/_snapshot/my_backup/snapshot_swk"
    35. curl -XDELETE "http://10.124.41.11:9209/_snapshot/my_backup"
    38. curl -XDELETE "http://10.124.41.11:9209/_snapshot/my_backup"
