  # The amount of time that a write will wait before fsyncing.  A duration

  # Values in the range of -100ms are recommended for non-SSD disks.

  # wal-fsync-delay = "0s"

  # Values without a size suffix are in bytes.

  # cache-snapshot-memory-size = "25m"

###

[coordinator]

  # The default time a write request will wait until a "timeout" error is returned to the caller.

  # write-timeout = "10s"

  # The maximum number of concurrent queries allowed to be executing at one time.  If a query is

  # executed and exceeds this limit, an error is returned to the caller.  This limit can be disabled

### [retention]

###

### Controls the enforcement of retention policies for evicting old data.

### [shard-precreation]

###

### Controls the precreation of shards, so they are available before data arrives.

### Only shards that, after creation, will have both a start- and end-time in the

### future, will ever be created. Shards are never precreated that would be wholly

### or partially in the past.

[shard-precreation]

  # Determines whether shard pre-creation service is enabled.

  # enabled = true

  # The interval of time when the check to pre-create new shards runs.

  # check-interval = "10m"

  # The default period ahead of the endtime of a shard group that its successor

  # group is created.

  # advance-period = "30m"

###

### Controls the system self-monitoring, statistics and diagnostics.

###

### The internal database for monitoring data is created automatically if

### if it does not already exist. The target retention within this database

### is called 'monitor' and is also created with a retention period of  days

### and a replication factor of , if it does not exist. In all cases the

### this retention policy is configured as the default for the database.

[monitor]

  # Whether to record statistics internally.

  # store-enabled = true

  # The destination database for recorded statistics

  # store-database = "_internal"

配置

InfluxDB管理

在配置auth-enabled = true之前 可以先创建管理员

如：

CREATE USER <username> WITH PASSWORD '<password>' WITH ALL PRIVILEGES
CREATE USER admin WITH PASSWORD 'liyouming' WITH ALL PRIVILEGES

看下：SHOW USERS

创建非管理员：

CREATE USER <username> WITH PASSWORD '<password>'

你也可以给非管理员分配管理员权限

GRANT ALL PRIVILEGES TO <username>

取消用户权限

REVOKE ALL PRIVILEGES FROM <username>

为用户分配数据库权限

GRANT [READ,WRITE,ALL] ON <database_name> TO <username>

取消用户的数据库权限

REVOKE [READ,WRITE,ALL] ON <database_name> FROM <username>

显示用户的数据库权限

SHOW GRANTS FOR <user_name>

设置密码

SET PASSWORD FOR <username> = '<password>'

删除用户

DROP USER <username>

其他

注意开启8086端口

firewall-cmd --zone=public --add-port=8086/tcp --permanent

firewall-cmd --reload
