InfluxDB

Amazon Linux

Add influx repository:

cat <<EOF | sudo tee /etc/yum.repos.d/influxdata.repo
[influxdata]
name = InfluxData Repository - Stable
baseurl = https://repos.influxdata.com/stable/\$basearch/main
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdata-archive_compat.key
EOF

Update and install:

yum update
yum install influxdb -y

Configure InfluxDB as follows:

vim /etc/influxdb/influxdb.conf

Into config file /etc/influxdb/influxdb.conf, enable HTTP support and auth, change the default value max-values-per-tag = 100000 to max-values-per-tag = 0.

...
[http]
  enabled = true
  bind-address = ":8086"
  auth-enabled = true
  ...
[data]
  ...
  max-values-per-tag = 0
  ...
...

Enable and start service and verify the status:

systemctl enable influxdb
systemctl start influxdb
systemctl status influxd

If everything is fine, you can enter the influx terminal as follows:

influx

Before doing anything, you must define a password for the admin user.

CREATE USER admin WITH PASSWORD 'pass' WITH ALL PRIVILEGES

Test the new password:

influx -username admin -password pass

Finally, create a database and a user to be used by zenit:

CREATE DATABASE zenit;
CREATE USER zenit WITH PASSWORD 'zenit';
GRANT ALL ON zenit TO zenit;
SHOW DATABASES;
