02-influxdb的權限管理

介紹

其實influxdb的權限語法和mysql基本相似，看完以後你基本就能瞭解；

授權語法

1. 創建用戶：CREATE USER <username> WITH PASSWORD '<password>'
2. 授權權限：GRANT [READ,WRITE,ALL] ON <database_name> TO <username>
3. 創建並授權：CREATE USER <username> WITH PASSWORD '<password>' WITH ALL PRIVILEGES
4. 取消授權：REVOKE ALL PRIVILEGES FROM <username>
5. 修改密碼：SET PASSWORD FOR <username> = '<password>'
6. 刪除用戶：DROP USER <username>

開啓登錄認證
vim /etc/influxdb/influxdb.conf

[http]
auth-enabled = true

[root@localhost tmp]# influx

Connected to http://localhost:8086 version 1.7.1
InfluxDB shell version: 1.7.1
Enter an InfluxQL query
> show databases
ERR: unable to parse authentication credentials
Warning: It is possible this error is due to not setting a database.
Please set a database with the command "use <database>".
> auth

授權操作

1.創建超級用戶
創建用戶：monitor
密碼：zabbix
權限：全部權限（超級用戶）
create user monitor with password 'zabbix' with all privileges

2.創建只讀用戶
用戶：monitor_ro
數據庫：monitordb
權限：指定數據庫的只讀權限

create user monitor_ro with password 'zabbix_apipwd'
grant read on monitordb to monitor_ro

3.創建可以寫用戶
用戶：monitor_rw
數據庫：monitordb
權限：指定數據庫的寫權限

create user monitor_rw with password 'zabbix_apipwd'
grant write on monitordb to monitor_rw

4.取消用戶授權
取消用戶授權：

REVOKE ALL PRIVILEGES FROM monitor_rw

5.查看所有用戶

SHOW USERS
user admin

---

monitor true
monitor_ro false
monitor_rw false

6.刪除用戶

DROP USER monitor_rw
