# CREATE REPOSITORY
|
|
## description
|
|
该语句用于创建仓库。仓库用于属于备份或恢复。仅 root 或 superuser 用户可以创建仓库。
|
|
语法：
|
|
CREATE [READ ONLY] REPOSITORY `repo_name`
|
|
WITH [BROKER `broker_name`|S3]
|
|
ON LOCATION `repo_location`
|
|
PROPERTIES ("key"="value", ...);
|
|
|
|
说明：
|
|
1. 仓库的创建，依赖于已存在的 broker 或者直接通过AWS s3 协议访问云存储
|
|
2. 如果是只读仓库，则只能在仓库上进行恢复。如果不是，则可以进行备份和恢复操作。
|
|
3. 根据 broker 或者S3的不同类型，PROPERTIES 有所不同，具体见示例。
|
|
|
|
## example
|
|
1. 创建名为 bos_repo 的仓库，依赖 BOS broker "bos_broker"，数据根目录为：bos://palo_backup
|
|
CREATE REPOSITORY `bos_repo`
|
|
WITH BROKER `bos_broker`
|
|
ON LOCATION "bos://palo_backup"
|
|
PROPERTIES
|
|
(
|
|
"bos_endpoint" = "http://gz.bcebos.com",
|
|
"bos_accesskey" = "bos_accesskey",
|
|
"bos_secret_accesskey"="bos_secret_accesskey"
|
|
);
|
|
|
|
2. 创建和示例 1 相同的仓库，但属性为只读：
|
|
CREATE READ ONLY REPOSITORY `bos_repo`
|
|
WITH BROKER `bos_broker`
|
|
ON LOCATION "bos://palo_backup"
|
|
PROPERTIES
|
|
(
|
|
"bos_endpoint" = "http://gz.bcebos.com",
|
|
"bos_accesskey" = "bos_accesskey",
|
|
"bos_secret_accesskey"="bos_accesskey"
|
|
);
|
|
|
|
3. 创建名为 hdfs_repo 的仓库，依赖 Baidu hdfs broker "hdfs_broker"，数据根目录为：hdfs://hadoop-name-node:54310/path/to/repo/
|
|
CREATE REPOSITORY `hdfs_repo`
|
|
WITH BROKER `hdfs_broker`
|
|
ON LOCATION "hdfs://hadoop-name-node:54310/path/to/repo/"
|
|
PROPERTIES
|
|
(
|
|
"username" = "user",
|
|
"password" = "password"
|
|
);
|
|
|
|
4. 创建名为 s3_repo 的仓库，直接链接云存储，而不通过broker.
|
|
CREATE REPOSITORY `s3_repo`
|
|
WITH S3
|
|
ON LOCATION "s3://s3-repo"
|
|
PROPERTIES
|
|
(
|
|
"AWS_ENDPOINT" = "http://s3-REGION.amazonaws.com",
|
|
"AWS_ACCESS_KEY" = "AWS_ACCESS_KEY",
|
|
"AWS_SECRET_KEY"="AWS_SECRET_KEY",
|
|
"AWS_REGION" = "REGION"
|
|
);
|
|
|
|
## keyword
|
|
CREATE, REPOSITORY
