Upgrading from Previous Versions

Upgrading from version 1.1 to 1.2.5

Version 1.2.5 is a drop-in replacement for version 1.1.x with no data migration required.

Version 1.2.5 introduces changes to the meta node configuration file and the data node configuration file. Please update the configuration files prior to upgrading to avoid any unnecessary downtime. The steps below outline the upgrade process and include a list of the required configuration changes.

Step 1: Download the 1.2.5 packages

Meta node package download

Ubuntu & Debian (64-bit)

wget https://dl.influxdata.com/enterprise/releases/influxdb-meta_1.2.4-c1.2.5_amd64.deb

RedHat & CentOS (64-bit)

wget https://dl.influxdata.com/enterprise/releases/influxdb-meta-1.2.4_c1.2.5.x86_64.rpm

Data node package download

Ubuntu & Debian (64-bit)

wget https://dl.influxdata.com/enterprise/releases/influxdb-data_1.2.4-c1.2.5_amd64.deb

RedHat & CentOS (64-bit)

wget https://dl.influxdata.com/enterprise/releases/influxdb-data-1.2.4_c1.2.5.x86_64.rpm

Step 2: Install the 1.2.5 packages

Meta node package Install

When you run the install command, your terminal asks if you’d like to keep your current configuration file or overwrite your current configuration file with the file for version 1.2.5. Please keep your current configuration file by entering N or O; we update the configuration file with the necessary changes for version 1.2.5 in step 3.

Ubuntu & Debian (64-bit)

sudo dpkg -i influxdb-meta_1.2.4-c1.2.5_amd64.deb

RedHat & CentOS (64-bit)

sudo yum localinstall influxdb-meta-1.2.4_c1.2.5.x86_64.rpm

Data node package install

When you run the install command, your terminal asks if you’d like to keep your current configuration file or overwrite your current configuration file with the file for version 1.2.5. Please keep your current configuration file by entering N or O; we update the configuration file with the necessary changes for version 1.2.5 in step 3.

Ubuntu & Debian (64-bit)

sudo dpkg -i influxdb-data_1.2.4-c1.2.5_amd64.deb

RedHat & CentOS (64-bit)

sudo yum localinstall influxdb-data-1.2.4_c1.2.5.x86_64.rpm

Step 3: Update the meta node configuration file

The configuration options in this section are not new to version 1.2.5. They were, however, missing from the sample configuration file (/etc/influxdb/influxdb-meta.conf) in version 1.1.x.

In the [meta] section of the configuration file (/etc/influxdb/influxdb-meta.conf), add the following options:

• auth-enabled = false
• https-private-key = “”
• https-insecure-tls = false
• consensus-timeout = “30s”

Those configuration options are set to their default settings. Follow the links for more information about those options.

Step 4: Update the data node configuration file

Most of the configuration options in this section are not new to version 1.2.5. They were, however, missing from the sample configuration file (/etc/influxdb/influxdb.conf) in version 1.1.x. The only actual configuration changes between version 1.1.1 and version 1.2.5 are:

• shard-writer-timeout is removed from the [cluster] section; the system now internally sets shard-writer-timeout
• max-row-limit in the [http] section is set to 0 by default instead of 10000

Uncomment all commented section headers: [cluster], [retention], [shard-precreation], [admin], [monitor], [subscriber], [http], [[graphite]], [[collectd]], [[opentsdb]], [[udp]], and [[continuous_queries]]. That change ensures that any future configuration changes to those sections will take effect upon a restart with no additional steps.

Under the hostname option at the top of the configuration file (/etc/influxdb/influxdb.conf), add gossip-frequency = “3s”.

In the [meta] section, add:

• meta-auth-enabled = false
• meta-internal-shared-secret = “”

In the [monitor] section, add remote-collect-interval = “10s”.

In the [[collectd]] section, add:

• security-level = “none”
• auth-file = “/etc/collectd/auth_file”

In the [http] section, change:

• max-row-limit = 10000 to max-row-limit = 0

In the [[udp]] section, add precision = “”.

In the [cluster] section, remove shard-writer-timeout = “5s”.

The added configuration options are set to their default settings. Follow the links for more information about those options.

Step 5: Restart the processes

Meta node restart

sysvinit systems

service influxdb-meta restart

systemd systems

sudo systemctl restart influxdb-meta

Data node Restart

sysvinit systems

service influxdb restart

systemd systems

sudo systemctl restart influxdb

Step 6: Confirm the upgrade

Check your nodes’ version numbers using the influxd-ctl show command. The influxd-ctl tool is available on all meta nodes.

~# influxd-ctl show
