# Installation - Ubuntu

We have confirmed the operation on Ubuntu 18.04.

# Install with apt-get

Alternatively you can install GridDB using apt.

If you prefer a video:

First create the Apt Repo File:

sudo sh -c 'echo "deb https://www.griddb.net/apt griddb/5.1 multiverse" >>  /etc/apt/sources.list.d/griddb.list'

And then import the key:

wget -qO - https://www.griddb.net/apt/griddb.asc | sudo apt-key add -

Then install GridDB:

$ sudo apt update
$ sudo apt install griddb-meta

With that command, GridDB, the c-client, the JDBC connector, and the GridDB CLI will be installed onto your machine.

And now, you can start your GridDB server

$ sudo systemctl start gridstore

To stop your server:

$ sudo systemctl stop gridstore

Once your server is running, you can drop into the shell like so:

$ sudo su gsadm
$ gs_sh

# User and directory structure after installation

# ⚠️ Note

  • When you install this package, a gsadm OS user are created in the OS. Execute the operating command as the gsadm user.
    Example
    # su - gsadm
$ pwd
/var/lib/gridstore
  • You do not need to set environment variable GS_HOME and GS_LOG. And the place of operating command is set to environment variable PATH.
  • There is Java client library (gridstore.jar) on /usr/share/java and a sample on /usr/gridb-XXX/docs/sample/programs.

When the GridDB package is installed, the following users and directory structure will be created.

# GridDB users and group

The OS group gridstore and user gsadm are created. Use the user gsadm as the operator of GridDB.

User Group GridDB home directory path
gsadm gridstore /var/lib/gridstore

The following environment variables are defined for user gsadm (in the .bash_profile file):

Environment variables Value Meaning
GS_HOME /var/lib/gridstore User gsadm/GridDB home directory
GS_LOG /var/lib/gridstore/log The output directory of the event log file of a node

# Directory hierarchy

The following two directories are created: GridDB home directory which contains files such as a node definition file and database files, the installation directory which contains the installed files.

# GridDB home directory
/var/lib/gridstore/                      #GridDB home directory
                   conf/                 # Definition file directory
                        gs_cluster.json  #Cluster definition file
                        gs_node.json     #Node definition file
                        password         #User definition file
                   data/                 # Database file directory
                   log/                  # Log directory

                gs_cluster.json         # Custer definition file
                gs_node.json            #Node definition file
