Installation

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 8083 is used for InfluxDB’s Admin panel
TCP port 8086 is used for client-server communication over InfluxDB’s HTTP API

Note: 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.

Ubuntu & Debian

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, you can add the InfluxData repository by using the following commands:

curl -sL https://repos.influxdata.com/influxdata-archive_compat.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, you can add the InfluxData repository by using the following commands:

curl -sL https://repos.influxdata.com/influxdata-archive_compat.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

And then to install and start the InfluxDB service:

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

RedHat & CentOS

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

RedHat 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/influxdata-archive_compat.key
EOF

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

sudo yum install influxdb
sudo service influxdb start

SLES & openSUSE

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

FreeBSD/PC-BSD

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.

macOS

Users of macOS 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

Hosted

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.

Configuration

For non-packaged installations, it is a best practice to generate a new configuration for each upgrade to ensure you have the latest features and settings. Any changes made in the old file will need to be manually ported to the newly generated file. Packaged installations will come with a configuration pre-installed, so this step may not be needed if you installed InfluxDB using a package manager (though it is handy to know either way).

Note: Newly generated configuration files have no knowledge of any local customizations or settings. Please make sure to double-check any configuration changes prior to deploying them.

To generate a new configuration file, run:

influxd config > influxdb.generated.conf

And then edit the influxdb.generated.conf file to have the desired configuration settings. When launching InfluxDB, point the process to the correct configuration file using the -config option. For example, use:

influxd -config influxdb.generated.conf

To launch InfluxDB with your newly generated configuration. In addition, a valid configuration file can be displayed at any time using the command influxd config.

If no -config option is supplied, InfluxDB will use an internal default configuration (equivalent to the output of influxd config).

Note: The influxd command has two similarly named flags. The config flag prints a generated default configuration file to STDOUT but does not launch the influxd process. The -config flag takes a single argument, which is the path to the InfluxDB configuration file to use when launching the process.

The config and -config flags can be combined to output the union of the internal default configuration and the configuration file passed to -config. The options specified in the configuration file will overwrite any internally generated configuration.

influxd config -config /etc/influxdb/influxdb.partial.conf

The output will show every option configured in the influxdb.partial.conf file and will substitute internal defaults for any configuration options not specified in that file.

The example configuration file shipped with the installer is for information only. It is an identical file to the internally generated configuration except that the example file has comments.

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 C3 class of machines.

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

Nightly and Development Versions

Nightly packages are available for Linux through the InfluxData package repository by using the nightly channel. Other package options can be found on the downloads page
