Installing Grafana, InfluxDB, Apache2 on AWS EC2: Step by Step

A medium-performance setup for Grafana on AWS. Private files at github.

Setup the instance

  • t3.large, Ubuntu 18 (or AWS Linux 2) as I’m familiar with it
  • Seperate root and data disks
  • Security group with 8083 (InfluxDB), 22 (SSH), 80 (www) and, optionally, 3000 (Grafana) open

Setup separate data volume

Key files

/var/lib/influxdb/       # backup via aws
/etc/influx/influx.conf # git
/etc/grafana/grafana.ini # git
/var/lib/grafana/ # backup via aws

Option 1: Mount a seperate volume for /var

Use instructions from AWS to mount an attached volume

sudo mkfs -t ext4 /dev/nvme1n1 # or xfs or ext4
sudo mkdir /data
mount /dev/nvme1e0 /data # temp...
sudo rsync -a /var/ /data/ # enable this sudo blkid # remember UUID sudo nano /etc/fstab # Add the following (change UUID) UUID=8a2ca8df-d123-4ff2-9183-33ba462826de /var ext4 defaults,nofail 0 2
# restart

Option 2: Symlink to /data

# mount a volume at /data and symlink:
sudo mkdir -p /data/etc/influxdb/
sudo mkdir -p /data/lib/influxdb/ 
cd /etc/influxdbsudo 
mv /etc/influxdb/influxdb.conf /data/etc/influxdbsudo
ln -s /data/etc/influxdb/influxdb.conf 
sudo chown -R influxdb:influxdb /data/etc/influxdb/ /data/lib/influxdb/
vim /etc/influxdb/influxdb.conf # to point to /data:
dir = "/data/lib/influxdb/data" wal-dir = "/data/lib/influxdb/wal" 
[meta] dir = "/data/lib/influxdb/meta"

Install the software:

Install as directed:


# need secure-link module  
sudo apt-get install nginx-extras
# start on boot
sudo systemctl enable nginx
sudo systemctl enable influxdb
sudo systemctl enable grafana-server


Configure InfluxDB

Add an admin user first:

influx>create user whoever with password [REDACTED]

Then configure via /etc/influxdb/influxdb.conf :

access-log-path = "/var/log/influxdb/influxdb-http.log" auth-enabled = true
max-connection-limit = 1000
max-concurrent-queries = 100
max-select-series = 100
query-timeout = "10s"
log-queries-after = "1s"
max-select-point = 1000000

query-stats-enabled = true
query-stats-enabled = false
run-interval = "1m"

And… restart to see changes

sudo systemctl restart influxdb
sudo systemctl status influxdb

Configure Grafana


root_url =
allow_sign_up = false
allow_org_create = false
auto_assign_org = false
# check if required?
enabled = true
enabled = true

Configure Nginx

See Access Grafana via token without login screen for details.
