Database doesn't exists/appear in influxdb after installation and configuraion

I’m trying to install influxdb on my ubuntu (14.04) server, however for some reason I don’t see my data base when I run show databases.

To download and install influxdb I used the following commands:

wget https://dl.influxdata.com/influxdb/releases/influxdb_1.7.2_amd64.deb
sudo dpkg -i influxdb_1.7.2_amd64.deb

Then, I set the configurations as such:

### [http]
###
### Controls how the HTTP endpoints are configured. These are the primary
### mechanism for getting data into and out of InfluxDB.
###

[http]
  # Determines whether HTTP endpoint is enabled.
   enabled = true

  # Determines whether the Flux query endpoint is enabled.
  # flux-enabled = false

  # The bind address used by the HTTP service.
   bind-address = ":8086"

and:

### [collectd]
###
### Controls one or many listeners for collectd data.
###

[[collectd]]
   enabled = true
   bind-address = ":8086"
   database = "collectd"
  # retention-policy = ""
  #
  # The collectd service supports either scanning a directory for multiple types
  # db files, or specifying a single db file.
   typesdb = "/usr/share/collectd/types.db"
  #

The first time I ran it, it said about /usr/share/collectd/types.db that there is no such file or directory, so I created the collectd directory and downloaded types.db file from collectd/types.db at master · collectd/collectd · GitHub using wget as such:
wget https://github.com/collectd/collectd/blob/master/src/types.db.
I restarted influxdb with sudo service influxdb restart.

To check that everything works fine I ran show databases in the terminal however I didn’t see my database , only the default one - _internal.
I checked the logs and all I can see there is: " unable to find “some_name_here” in TypesDB.
What am I missing here? How can I fix this?
Thanks in advance.

This is an HTML page: collectd/types.db at master · collectd/collectd · GitHub

This is the raw (actual) file: https://github.com/collectd/collectd/raw/master/src/types.db

Does it work with:

collectdpath="/usr/share/collectd"; \
sudo mkdir -p "${collectdpath}"; \
sudo chown "$(id -u)" "${collectdpath}"; \
chmod o+rx "${collectdpath}"; \
(cd "${collectdpath}"; \
 wget 'https://github.com/collectd/collectd/raw/master/src/types.db'); \
chmod o+r "${collectdpath}/types.db"

You may need to create the database either with the HTTP API or with the InfluxDB shell CLI:

With the CLI:

echo "CREATE DATABASE collectd" | influx
echo "SHOW DATABASES" | influx

With the HTTP API (and authentication) according to inanzzz | CollectD, InfluxDB and Grafana integration :

curl -i -XPOST http://localhost:8086/query -u inanzzz:123123 \
  --data-urlencode "q=CREATE DATABASE collectd"
