Prerequisites
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation OrientDB open source NoSQL database management system on a CentOS 7 server.
Install OrientDB on CentOS 7
Step 1. First let’s start by ensuring your system is up-to-date.
yum clean all yum -y update
Step 2. Installing OrientDB.
First of all, create a new user to run OrientDB:
adduser orientdb -d /opt/orientdb
Now you can download the OrientDB binary archive by running the following command:
cd /opt/orientdb/ wget https://orientdb.com/download.php?file=orientdb-community-importers-2.2.29.tar.gz -O /opt/orientdb/orientdb.tar.gz
Once the package is downloaded we will untar and move the extracted folder to the /opt/orientdb:
tar -xf orientdb.tar.gz mv orientdb-community*/* .
Make the orientdb user the owner of the extracted files:
chown -R orientdb:orientdb /opt/orientdb
Step 3. Starting the OrientDB Server.
OrientDB provides an installer script for you to start the server. Switch to the OrientDB user:
su - orientdb sudo bin/server.sh
OrientDB should now prompt for the root password with a message like the one below:
+---------------------------------------------------------------+ | WARNING: FIRST RUN CONFIGURATION | +---------------------------------------------------------------+ | This is the first time the server is running. Please type a | | password of your choice for the 'root' user or leave it blank | | to auto-generate it. | | | | To avoid this message set the environment variable or JVM | | setting ORIENTDB_ROOT_PASSWORD to the root password to use. | +---------------------------------------------------------------+
Step 4. Configure OrientDB Daemon.
Create a new ststemd service to easily manage OrientDB start and stop:
nano /etc/systemd/system/orientdb.service
Paste the following content:
[Unit] Description=OrientDB service After=network.target [Service] Type=simple ExecStart=/opt/orientdb/bin/server.sh User=orientdb Group=orientdb Restart=always RestartSec=9 StandardOutput=syslog StandardError=syslog SyslogIdentifier=orientdb [Install] WantedBy=multi-user.target
Reload systemd daemon service:
systemctl daemon-reload
Start OrientDB and enable for starting at boot time:
systemctl start orientdb systemctl enable orientdb
