Version Upgrade
This page covers the basic upgrade process for local GridGain installations.
Upgrading ZIP Installation
Before Upgrade
Before performing an upgrade, consider that it may accidentally overwrite important data stored in the installation directory. If you plan to do an upgrade, it’s strongly recommended moving critical data outside the installation folder:
-
The
workfolder contains persistent storage and all data required for node operation. -
The
etcfolder holds the node’s configuration files, which are loaded at startup. -
The
logfolder stores all log files generated by the node.
You can change the location of these folders by editing the etc/vars.env file or by setting corresponding environment variables.
Upgrade
To upgrade a GridGain ZIP installation, follow these steps:
-
First stop all the nodes in the cluster. Do not perform an upgrade while the cluster is running, unless the Rolling Upgrade is used. Navigate to the existing installation’s
etcfolder and delete theignite.version.fullfile. -
Replace the binaries with the new version. Copy the
ignite.version.fullfile from the new ZIP’setcdirectory into yours. -
Start the cluster again.
Upgrading Docker Installation
When updating a docker installation, all information in the container with GridGain will be lost. To keep your configuration, logs and other data, mount a volume for any persistent data you need.
Upgrading DEB/RPM Package Installation
You can use the standard update command provided by your operating system’s package manager to upgrade a package-based installation.
To perform an upgrade, take the following steps:
-
First stop all the nodes in the cluster. Do not perform an upgrade while the cluster is running, unless the Rolling Upgrade is used.
-
Then update the installation:
sudo apt-get upgrade gridgain9-db-gridgain-9.1.0.debsudo rpm -U gridgain9-db-gridgain-9.1.0.noarch.rpm -
Once the update is completed, start the cluster.
