# Installation - CentOS

We have confirmed the operation on CentOS 7.9.

# Install with yum

Alternatively you can install GridDB using YUM.

First create the Yum Repo File:

sudo cat > /etc/yum.repos.d/griddb.repo << EOF

Then install GridDB:

$ sudo yum update
$ sudo yum -y install griddb-meta

# ⚠️ Note

If you would like to use a previous version of GridDB, you can change the baseurl to match that version (for example, version 4.3)

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 (java is required):

$ sudo su gsadm
$ gs_sh

# User and directory structure after installation

The following are the default values when you install and start a new GridDB instance.

This is the output of gs_stat -u <user>/<pass> (the default user and password are both admin)

gsadm@server:/home$ gs_stat -u admin/admin
A00105: GS_HOME, GS_LOG environment variable not set.
gsadm@server:/home$ source ~/.bash_profile
gsadm@server:/home$ gs_stat -u admin/admin

# ⚠️ Note

  • When you install this package, a gsadm OS user are created in the OS. Execute the operating command as the gsadm user.
    # su - gsadm
    $ pwd
  • 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
# Installation directory
Installation directory
            bin/                        # Operation command, module directory
            conf/                       #Definition file directory
                gs_cluster.json         # Custer definition file
                gs_node.json            #Node definition file
                password                #User definition file

# Install with RPM

Please download the appropriate package files from the GridDB Github page.

Then, install the package of your target OS.

$ sudo rpm -ivh griddb_nosql-X.X.X-linux.x86_64.rpm
X.X.X means version

# Build/execution method

An example on how to build and execute a program is as shown.

[For Java]

  1. Setting environment variables
  2. Edit java Sample file to adhere to network mode (GridDB default is now FIXED_LIST mode, this uses notification_member instead of host & port)
  3. Copy the sample program to the gsSample directory
  4. Build
  5. Run
$ export CLASSPATH=${CLASSPATH}:/usr/share/java/gridstore.jar:.
$ mkdir gsSample
$ vim gsSample/Sample1.java
$ cp /usr/gridstore-X.X.X/docs/sample/program/Sample1.java gsSample/.
$ javac gsSample/Sample1.java
$ java gsSample/Sample1 setup_cluster_name admin your_password

# GridDB uninstallation

If you no longer need GridDB, uninstall the package. Execute the following procedure with root authority.


$ sudo rpm -e griddb_nosql

# ⚠️ Note

  • Files under the GridDB home directory such as definition files and data files will not be uninstalled. If you do not need it, delete it manually.
