| [2] | If Firewalld is running and also you'd like to access to InfluxDB from other hosts, allow service port. |
|
[root@dlp ~]# firewall-cmd --add-port=8086/tcp success [root@dlp ~]# firewall-cmd --runtime-to-permanent success |
| [3] | Configure InfluxDB. By default, authentication is disabled, all users can use InfluxDB with privileges. So enable authentication first. |
|
# create an admin user # [admin] ⇒ specify any username you like # [adminpassword] ⇒ set any password [root@dlp ~]# influx -execute "create user admin with password 'adminpassword' with all privileges" [root@dlp ~]# influx -execute "show users" user admin ---- ----- admin true
[root@dlp ~]#
vi /etc/influxdb/influxdb.conf [http] .... .... # The bind address used by the HTTP service. # bind-address = ":8086" # Determines whether user authentication is enabled over HTTP/HTTPS. # line 263 : uncomment and change auth-enabled = true[root@dlp ~]# systemctl restart influxdb
|
| [4] | After enabling authentication, access InfluxDB CLI like follows. |
|
# add user info on CLI [root@dlp ~]# influx -username admin -password adminpassword
