ineo

A simple but useful Neo4j instance manager.

Neo4j is a great graph database, however its architecture was designed to work with just one database for each Neo4j server instance. This issue could be a problem when we are developing an application with an environment for testing and developing, or just when we are creating or serving two or more applications.

Ineo figure out this issue allowing to manage different Neo4j instances on different ports.

Requirements

• Bash. Installed by default on OS X and Ubuntu
• Curl. Installed by default on OS X and Ubuntu
• Java. In order to start the Neo4j server

Installation

1. Execute the line bellow on your terminal:

   curl -sSL http://getineo.cohesivestack.com | bash -s install

2. Restart your terminal or execute the line bellow:

   source ~/.bashrc

How to use

Create an instance

Imagine that you need a database for an application called my_db:

$ ineo create my_db

  The instance my_db was created successfully

Show instance information

Show the information about the recently instance created:

$ ineo instances

  > instance 'my_db'
    VERSION: 2.2.2
    PATH:    /home_path/.ineo/instances/my_db
    PORT:    7474
    HTTPS:   7475

Ineo downloaded the last available version of Neo4j and created an instance database ready to use on the port 7474 and 7475 for ssl.

Start instance

Start the database instance for using

$ ineo start my_db

  start 'my_db'
  Starting Neo4j Server...WARNING: not changing user
process [19773]... waiting for server to be ready....... OK.
http://localhost:7474/ is ready.

Show instance status

Show the status of the database instance

$ ineo status my_db

  status 'my_db'
  Neo4j Server is running at pid 19773

Stop instance

Stop the database instance

$ ineo stop my_db

  status 'my_db'
  Neo4j Server is running at pid 19773

Restart instance

It's also possible to restart a database instance

$ ineo restart my_db

Using with multiple instances

The main objetive of Ineo is managing different Neo4j instances.

Create an instance with a specific port

Imagine that you want to create an instance for testing. This should be created with another http port, so both instances can be running simultaneously.

$ ineo create -p8486 my_db_test

  The instance my_db_test was successfully created

Now, when you show the information about instances, you see:

$ ineo instances

  > instance 'my_db'
    VERSION: 2.2.2
    PATH:    /home_path/.ineo/instances/my_db
    PORT:    7474
    HTTPS:   7475

  > instance 'my_db_test'
    VERSION: 2.2.2
    PATH:    /home_path/.ineo/instances/my_db_test
    PORT:    8486
    HTTPS:   8487

Start multiple instances

All instances can be started using the command start without an instance name.

$ ineo start

  WARNING: A Neo4j instance name is not specified!

  Are you sure you want to start all instances? (y/n) y


  start 'my_db'
  Starting Neo4j Server...WARNING: not changing user
process [20790]... waiting for server to be ready....... OK.
http://localhost:7474/ is ready.


  start 'my_db_test'
  Starting Neo4j Server...WARNING: not changing user
process [20930]... waiting for server to be ready....... OK.
http://localhost:8485/ is ready.

Show status for multiple instances

It's possible to show the status of all instances using the command stop without instance name.

$ ineo status

  status 'my_db'
  Neo4j Server is running at pid 20790


  status 'my_db_test'
  Neo4j Server is running at pid 20930

Stop multiple instances

All instances can be stopped using the command stop without instance name.

$ ineo stop

  WARNING: A Neo4j instance name is not specified!

  Are you sure you want to stop all instances? (y/n) y


  stop 'my_db'
  Stopping Neo4j Server [20790].... done


  stop 'my_db_test'
  Stopping Neo4j Server [20930].... done

Restart multiple instance

It's also possible to restart multiple instances using the command restart without instance name.

$ ineo restart

Changing the port

You can change the port to a specific instance.

$ ineo set-port my_db 9494

The ssl port as well.

$ ineo set-port -s my_db 9494

Installing a specific version

The command create always uses the last Neo4j version available of the current Ineo version installed. However is possible to specify another version using the option -v

ineo create -v 2.1.8

The command versions

The command versions shows all Neo4j versions available for installing.

$ ineo versions

The command install

There is a command to install Ineo. Use this command only if you don't have already installed Ineo.

$ ineo install

Installing in a specific directory

Ineo is installed in $HOME/.ineo by default, however is possible to specify another directory using the option -d.

$ install -d ~/.ineo-custom-path

If you are installing from curl:

$ curl -sSL http://getineo.cohesivestack.com | bash -s install -d ~/.ineo-custom-path
