备份命令
| # mongodump -h 127.0.0.1:27229 -u root -p pw123456 --authenticationDatabase admin -o /data/backup/mongoDB |
报错如下
| Failed: error getting collections for database `admin`: error running `listCollections`. Database: `admin` Err: not authorized on admin to execute command { lcursor: {}, $readPreference: { mode: "secondaryPreferred" }, $db: "admin" } |
解决办法:
> use admin

> db.grantRolesToUser ( "root", [ { role: "__system", db: "admin" } ] ) #授权给admin用户对system.version表执行命令的权限
