--- title: Upgrade InfluxDB Enterprise v1 clusters description: Upgrade to the latest version of InfluxDB Enterprise. url: https://docs.influxdata.com/enterprise_influxdb/v1/administration/upgrading/ estimated_tokens: 4587 product: InfluxDB Enterprise v1 version: v1 --- # Upgrade InfluxDB Enterprise v1 clusters To successfully perform a rolling upgrade of InfluxDB Enterprise clusters to 1.12.4, complete the following steps: 1. [Back up your cluster](#back-up-your-cluster). 2. [Upgrade meta nodes](#upgrade-meta-nodes). 3. [Upgrade data nodes](#upgrade-data-nodes). > ***Note:*** A rolling upgrade lets you update your cluster with zero downtime. To downgrade to an earlier version, complete the following procedures, replacing the version numbers with the version that you want to downgrade to. ## Back up your cluster Before performing an upgrade, create a full backup of your InfluxDB Enterprise cluster. Also, if you create incremental backups, trigger a final incremental backup. > ***Note:*** For information on performing a final incremental backup or a full backup, see [Back up and restore InfluxDB Enterprise clusters](/enterprise_influxdb/v1/administration/backup-and-restore/). ## Upgrade meta nodes Complete the following steps to upgrade meta nodes: 1. [Download the meta node package](#download-the-meta-node-package). 2. [Install the meta node package](#install-the-meta-node-package). 3. [Update the meta node configuration file](#update-the-meta-node-configuration-file). 4. [Restart the `influxdb-meta` service](#restart-the-influxdb-meta-service). 5. Repeat steps 1-4 for each meta node in your cluster. 6. [Confirm the meta nodes upgrade](#confirm-the-meta-nodes-upgrade). ### Download the meta node package ##### Ubuntu and Debian (64-bit) ```bash wget https://dl.influxdata.com/enterprise/releases/influxdb-meta_1.12.4-c1.12.4_amd64.deb ``` ##### RedHat and CentOS (64-bit) ```bash wget https://dl.influxdata.com/enterprise/releases/influxdb-meta-1.12.4-c1.12.4.x86_64.rpm ``` ### Install the meta node package ##### Ubuntu and Debian (64-bit) ```bash sudo dpkg -i influxdb-meta_1.12.4-c1.12.4_amd64.deb ``` ##### RedHat and CentOS (64-bit) ```bash sudo yum localinstall influxdb-meta-1.12.4-c1.12.4.x86_64.rpm ``` ### Update the meta node configuration file Migrate any custom settings from your previous meta node configuration file. To enable HTTPS, you must update the meta node configuration file (`influxdb-meta.conf`). For information, see [Enable HTTPS within the configuration file for each Meta Node](/enterprise_influxdb/v1/guides/https_setup/#set-up-https-in-an-influxdb-enterprise-cluster). ### Restart the `influxdb-meta` service ##### sysvinit systems ```bash service influxdb-meta restart ``` ##### systemd systems ```bash sudo systemctl restart influxdb-meta ``` ### Confirm the meta nodes upgrade After upgrading ***all*** meta nodes, check your node version numbers using the `influxd-ctl show` command. The [`influxd-ctl` utility](/enterprise_influxdb/v1/tools/influxd-ctl/) is available on all meta nodes. ```bash ~# influxd-ctl show Data Nodes ========== ID TCP Address Version 4 rk-upgrading-01:8088 1.8.x_c1.8.y 5 rk-upgrading-02:8088 1.8.x_c1.8.y 6 rk-upgrading-03:8088 1.8.x_c1.8.y Meta Nodes ========== TCP Address Version rk-upgrading-01:8091 1.12.4-c1.12.4 # 1.12.4-c1.12.4 = 👍 rk-upgrading-02:8091 1.12.4-c1.12.4 rk-upgrading-03:8091 1.12.4-c1.12.4 ``` Ensure that the meta cluster is healthy before upgrading the data nodes. ## Upgrade data nodes Complete the following steps to upgrade data nodes: 1. [Stop traffic to data nodes](#stop-traffic-to-the-data-node). 2. [Download the data node package](#download-the-data-node-package). 3. [Install the data node package](#install-the-data-node-package). 4. [Update the data node configuration file](#update-the-data-node-configuration-file). 5. For Time Series Index (TSI) only. [Rebuild TSI indexes](#rebuild-tsi-indexes). 6. [Restart the `influxdb` service](#restart-the-influxdb-service). 7. [Restart traffic to data nodes](#restart-traffic-to-data-nodes). 8. Repeat steps 1-7 for each data node in your cluster. 9. [Confirm the data nodes upgrade](#confirm-the-data-nodes-upgrade). ### Stop traffic to the data node To stop traffic to data nodes, **do one of the following:** - **Disable traffic to data nodes in the node balancer** - If you have access to the load balancer configuration, use your load balancer to stop routing read and write requests to the data node server (port 8086). - If you cannot access the load balancer configuration, work with your networking team to prevent traffic to the data node server before continuing to upgrade. Disabling traffic to a data node in the load balancer still allows other data node in the cluster to write to current data node. - **Stop the `influxdb` service on the data node** **sysvinit:** ```bash service influxdb stop ``` **systemd:** ```bash sudo systemctl stop influxdb ``` Stopping the `influxdb` process the data node takes longer than disabling traffic at the load balancer, but it ensures all writes stop, including writes from other data nodes in the cluster. ### Download the data node package ##### Ubuntu and Debian (64-bit) ```bash wget https://dl.influxdata.com/enterprise/releases/influxdb-data_1.12.4-c1.12.4_amd64.deb ``` ##### RedHat and CentOS (64-bit) ```bash wget https://dl.influxdata.com/enterprise/releases/influxdb-data-1.12.4-c1.12.4.x86_64.rpm ``` ### Install the data node package When you run the install command, you’re prompted to keep or overwrite your current configuration file with the file for version 1.12.4. Enter `N` or `O` to keep your current configuration file. You’ll make the configuration changes for version 1.12.4 in the next procedure, [Update the data node configuration file](#update-the-data-node-configuration-file). ##### Ubuntu & Debian (64-bit) ```bash sudo dpkg -i influxdb-data_1.12.4-c1.12.4_amd64.deb ``` ##### RedHat & CentOS (64-bit) ```bash sudo yum localinstall influxdb-data-1.12.4-c1.12.4.x86_64.rpm ``` ### Update the data node configuration file Migrate any custom settings from your previous data node configuration file. - To enable HTTPS, see [Enable HTTPS within the configuration file for each Data Node](/enterprise_influxdb/v1/guides/https_setup/#set-up-https-in-an-influxdb-enterprise-cluster). - To enable TSI, open `/etc/influxdb/influxdb.conf`, and then adjust and save the settings shown in the following table. | Section | Setting | | --- | --- | | [data] | To use Time Series Index (TSI) disk-based indexing, add index-version = "tsi1"To use TSM in-memory index, add index-version = "inmem"Add wal-fsync-delay = "0s"Add max-concurrent-compactions = 0Setcache-max-memory-size to 1073741824 | | [cluster] | Add pool-max-idle-streams = 100Addpool-max-idle-time = "1m0s"Remove max-remote-write-connections | | [anti-entropy] | Add enabled = trueAdd check-interval = "30s"Add max-fetch = 10 | | [admin] | Remove entire section. | For more information about TSI, see [TSI overview](/enterprise_influxdb/v1/concepts/time-series-index/) and [TSI details](/enterprise_influxdb/v1/concepts/tsi-details/). ### Rebuild TSI indexes Complete the following steps for Time Series Index (TSI) only. 1. Delete all `_series` directories in the `/data` directory (by default, stored at `/data//_series`). 2. Delete all TSM-based shard `index` directories (by default, located at `/data///index`). 3. Use the [`influx_inspect buildtsi`](/enterprise_influxdb/v1/tools/influx_inspect#buildtsi) utility to rebuild the TSI index. For example, run the following command: ```js influx_inspect buildtsi -datadir /yourDataDirectory -waldir /wal ``` Replacing `yourDataDirectory` with the name of your directory. Running this command converts TSM-based shards to TSI shards or rebuilds existing TSI shards. > **Note:** Run the `buildtsi` command using the same system user that runs the `influxd` service, or a user with the same permissions. ### Restart the `influxdb` service Restart the `influxdb` service to restart the data nodes. Do one of the following: - **If the `influxdb` service is still running**, but isn’t receiving traffic from the load balancer: **sysvinit:** ```bash service influxdb restart ``` **systemd:** ```bash sudo systemctl restart influxdb ``` - **If the `influxdb` service is stopped**: **sysvinit:** ```bash service influxdb start ``` **systemd:** ```bash sudo systemctl start influxdb ``` ### Restart traffic to data nodes Restart routing read and write requests to the data node server (port 8086) through your load balancer. > **Note:** Allow the hinted handoff queue (HHQ) to write all missed data to the updated node before upgrading the next data node. Once all data has been written, the disk space used in the hinted handoff queue should be 0. Check the disk space on your hh directory by running the \[`du`\] command, for example, `du /var/lib/influxdb/hh`. ### Confirm the data nodes upgrade After upgrading ***all*** data nodes, check your node version numbers using the `influxd-ctl show` command. The [`influxd-ctl` utility](/enterprise_influxdb/v1/tools/influxd-ctl/) is available on all meta nodes. ```bash ~# influxd-ctl show Data Nodes ========== ID TCP Address Version 4 rk-upgrading-01:8088 1.12.4-c1.12.4 # 1.12.4-c1.12.4 = 👍 5 rk-upgrading-02:8088 1.12.4-c1.12.4 6 rk-upgrading-03:8088 1.12.4-c1.12.4 Meta Nodes ========== TCP Address Version rk-upgrading-01:8091 1.12.4-c1.12.4 rk-upgrading-02:8091 1.12.4-c1.12.4 rk-upgrading-03:8091 1.12.4-c1.12.4 ``` If you have any issues upgrading your cluster, contact InfluxData support.
