Install on Ubuntu and Debian

concept

Operational Insights can be installed on Ubuntu Linux and Debian Linux for production and development use-cases. Root installation is supported.

Use the instructions on this page to install Operational Insights on Ubuntu using Couchbase-provided deb packages.

Before You Install

Operational Insights works out-of-the-box with most OS configurations. The procedures on this page assume that you work from a clean system, your system meets the system resource requirements, and your operating system version is a supported platform.

For production deployments, make sure to follow the deployment guidelines so that your systems and environment are properly sized and configured before installation.

Basic Installation

You must be logged in as root (superuser) or use sudo to run the installation commands.

Install Using Apt

The Advanced Package Tool (apt) provides the simplest and most comprehensive way to install Operational Insights on Ubuntu and Debian. This method involves downloading and installing a small meta package from Couchbase, which apt uses to automatically download and install Operational Insights and its dependencies.

Download the meta package:

curl -O https://packages.couchbase.com/releases/couchbase-release/couchbase-release-1.0-noarch.deb

Install the meta package:
```
sudo dpkg -i ./couchbase-release-1.0-noarch.deb
```
The meta package installs the necessary information for apt to retrieve all the necessary Operational Insights installation packages and dependencies.
Reload the local package database:
```
sudo apt-get update
```
Install Operational Insights:
- To install the latest release
  sudo apt-get install operational-insights
- To install a specific release
  1. List the available releases.
    
    apt list -a operational-insights
    
    Available releases are listed with their full version-build number:
    
    operational-insights/xenial 2.0.0-1060 amd64
  2. Specify a release to install it:
    
    sudo apt-get install operational-insights=[.var] version-string
    
    Using the example listing from the previous step, the resulting installation command would be:
    
    sudo apt-get install operational-insights=2.0.0-1060

Install Using Deb Package

Install Operational Insights on Ubuntu and Debian using a full deb package provided by Couchbase.

Download the appropriate package from the Couchbase downloads page.
Reload the local package database:
```
sudo apt-get update
```
Install Operational Insights:
```
sudo dpkg -i ./[.var] package-name.deb
```
If dpkg reports any errors about missing dependencies, issue the following command to download and install those dependencies from the Internet:
```
sudo apt-get -f install
```
Once installation is complete, Operational Insights starts automatically. It continues to start automatically at run levels 2, 3, 4, and 5, and explicitly shut down at run levels 0, 1, and 6. You can use the systemctl command to start and stop Operational Insights, and check the current status. On earlier operating systems, use service. For more information, see Start and Stop Operational Insights.
Open a web browser and open the Operational Insights Web Console to verify that the installation was successful and that the node is available.

Next Steps

Following installation and start-up of Operational Insights, you must initialize and provision a node.

If it’s the first node in a deployment, initialization and provisioning happens all at once when you create a cluster of one.

For more information, see Create a Cluster.
If you already have an existing cluster, the node is initialized and provisioned when you add it to the cluster.

For more information, see Add a Node and Rebalance.
Optionally, you can perform initialization explicitly and independently of provisioning, as a prior process, to establish certain configurations, such as custom disk-paths.

For more information, see Initialize a Node.
