Installation

Warning! This page documents an old version of InfluxDB, which is no longer actively developed. InfluxDB v1.4 is the most recent stable version of InfluxDB.

This page provides directions for installing, starting, and configuring InfluxDB.

Requirements

Installation of the InfluxDB package may require root or administrator privileges in order to complete successfully.

Networking

By default, InfluxDB uses the following network ports:

  • TCP port 8086 is used for client-server communication over InfluxDB’s HTTP API
  • TCP port 8088 is used for the RPC service for backup and restore

In addition to the ports above, InfluxDB also offers multiple plugins that may require custom ports. All port mappings can be modified through the configuration file, which is located at /etc/influxdb/influxdb.conf for default installations.

NTP

InfluxDB uses a host’s local time in UTC to assign timestamps to data and for coordination purposes. Use the Network Time Protocol (NTP) to synchronize time between hosts; if hosts’ clocks aren’t synchronized with NTP, the timestamps on the data written to InfluxDB can be inaccurate.

Installation

For users who don’t want to install any software and are ready to use InfluxDB, you may want to check out our managed hosted InfluxDB offering.

For instructions on how to install the Debian package from a file, please see the downloads page.

Debian and Ubuntu users can install the latest stable version of InfluxDB using the apt-get package manager.

For Ubuntu users, add the InfluxData repository with the following commands:

curl -sL https://repos.influxdata.com/influxdb.key | sudo apt-key add -
source /etc/lsb-release
echo "deb https://repos.influxdata.com/${DISTRIB_ID,,} ${DISTRIB_CODENAME} stable" | sudo tee /etc/apt/sources.list.d/influxdb.list

For Debian users, add the InfluxData repository:

curl -sL https://repos.influxdata.com/influxdb.key | sudo apt-key add -
source /etc/os-release
test $VERSION_ID = "7" && echo "deb https://repos.influxdata.com/debian wheezy stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
test $VERSION_ID = "8" && echo "deb https://repos.influxdata.com/debian jessie stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
test $VERSION_ID = "9" && echo "deb https://repos.influxdata.com/debian stretch stable" | sudo tee /etc/apt/sources.list.d/influxdb.list

Then, install and start the InfluxDB service:

sudo apt-get update && sudo apt-get install influxdb
sudo service influxdb start

Or if your operating system is using systemd (Ubuntu 15.04+, Debian 8+):

sudo apt-get update && sudo apt-get install influxdb
sudo systemctl start influxdb

For instructions on how to install the RPM package from a file, please see the downloads page.

Red Hat and CentOS users can install the latest stable version of InfluxDB using the yum package manager:

cat <<EOF | sudo tee /etc/yum.repos.d/influxdb.repo
[influxdb]
name = InfluxDB Repository - RHEL \$releasever
baseurl = https://repos.influxdata.com/rhel/\$releasever/\$basearch/stable
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdb.key
EOF

Once repository is added to the yum configuration, install and start the InfluxDB service by running:

sudo yum install influxdb
sudo service influxdb start

Or if your operating system is using systemd (CentOS 7+, RHEL 7+):

sudo yum install influxdb
sudo systemctl start influxdb

There are RPM packages provided by openSUSE Build Service for SUSE Linux users:

# add go repository
zypper ar -f obs://devel:languages:go/ go
# install latest influxdb
zypper in influxdb

InfluxDB is part of the FreeBSD package system. It can be installed by running:

sudo pkg install influxdb

The configuration file is located at /usr/local/etc/influxd.conf with examples in /usr/local/etc/influxd.conf.sample.

Start the backend by executing:

sudo service influxd onestart

To have InfluxDB start at system boot, add influxd_enable="YES" to /etc/rc.conf.

Users of OS X 10.8 and higher can install InfluxDB using the Homebrew package manager. Once brew is installed, you can install InfluxDB by running:

brew update
brew install influxdb

To have launchd start InfluxDB at login, run:

ln -sfv /usr/local/opt/influxdb/*.plist ~/Library/LaunchAgents

And then to start InfluxDB now, run:

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.influxdb.plist

Or, if you don’t want/need launchctl, in a separate terminal window you can just run:

influxd -config /usr/local/etc/influxdb.conf

Configuration

The system has internal defaults for every configuration file setting. View the default configuration settings with the influxd config command.

Most of the settings in the local configuration file (/etc/influxdb/influxdb.conf) are commented out; all commented-out settings will be determined by the internal defaults. Any uncommented settings in the local configuration file override the internal defaults. Note that the local configuration file does not need to include every configuration setting.

There are two ways to launch InfluxDB with your configuration file:

  • Point the process to the correct configuration file by using the -config option:

    influxd -config /etc/influxdb/influxdb.conf
    
  • Set the environment variable INFLUXDB_CONFIG_PATH to the path of your configuration file and start the process. For example:

    echo $INFLUXDB_CONFIG_PATH
    /etc/influxdb/influxdb.conf
    
    
    influxd
    

InfluxDB first checks for the -config option and then for the environment variable.

See the Configuration documentation for more information.

Hardware

We recommend using two SSD volumes. One for the influxdb/wal and one for the influxdb/data. Depending on your load each volume should have around 1k-3k provisioned IOPS. The influxdb/data volume should have more disk space with lower IOPS and the influxdb/wal volume should have less disk space with higher IOPS.

Each machine should have a minimum of 8G RAM.

We’ve seen the best performance with the R4 class of machines, as they provide more memory than either of the C3/C4 class and the M4 class.

Configuring the Instance

This example assumes that you are using two SSD volumes and that you have mounted them appropriately. This example also assumes that each of those volumes is mounted at /mnt/influx and /mnt/db. For more information on how to do that see the Amazon documentation on how to Add a Volume to Your Instance.

Config File

You’ll have to update the config file appropriately for each InfluxDB instance you have.

...

[meta]
  dir = "/mnt/db/meta"
  ...

...

[data]
  dir = "/mnt/db/data"
  ...
wal-dir = "/mnt/influx/wal"
  ...

...

[hinted-handoff]
    ...
dir = "/mnt/db/hh"
    ...

Permissions

When using non-standard directories for InfluxDB data and configurations, also be sure to set filesystem permissions correctly:

chown influxdb:influxdb /mnt/influx
chown influxdb:influxdb /mnt/db
