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

Please check releases for the latest version available.

1. Execute the line below on your terminal:

   curl -sSL https://raw.githubusercontent.com/cohesivestack/ineo/v2.1.0/ineo | bash -s install
   

2. Restart your terminal or execute the line below to set proper environment:

   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: 3.5.16
    EDITION: community
    PATH:    /home_path/.ineo/instances/my_db
    PORT:    7474
    HTTPS:   7475
    BOLT:    7476

Ineo downloaded the last available version of Neo4j and created an instance database ready to use on port 7474 and 7475 for SSL or bolt port 7476.

Start instance

Start the database instance for using

$ ineo start my_db

  start 'my_db'
  Active database: graph.db
Directories in use:
  home:         /home_path/.ineo/instances/my_db
  config:       /home_path/.ineo/instances/my_db/conf
  logs:         /home_path/.ineo/instances/my_db/logs
  plugins:      /home_path/.ineo/instances/my_db/plugins
  import:       /home_path/.ineo/instances/my_db/import
  data:         /home_path/.ineo/instances/my_db/data
  certificates: /home_path/.ineo/instances/my_db/certificates
  run:          /home_path/.ineo/instances/my_db/run
Starting Neo4j.
Started neo4j (pid 12345). It is available at http://0.0.0.0:7474/
There may be a short delay until the server is ready.
See /home_path/.ineo/instances/my_db/logs/neo4j.log for current status.

Show instance status

Show the status of the database instance

$ ineo status my_db

  status 'my_db'
  Neo4j is running at pid 12345

Stop instance

Stop the database instance

$ ineo stop my_db

  stop 'my_db'
  Stopping Neo4j.. stopped

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: 3.5.16
    EDITION: community
    PATH:    /home_path/.ineo/instances/my_db
    PORT:    7474
    HTTPS:   7475
    BOLT:    7476

  > instance 'my_db_test'
    VERSION: 3.5.16
    EDITION: community
    PATH:    /home_path/.ineo/instances/my_db_test
    PORT:    8486
    HTTPS:   8487
    BOLT:    8488

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'

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 is running at pid 12345

  status 'my_db_test'
  Neo4j is running at pid 23456

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.. stopped

  stop 'my_db_test'
  Stopping Neo4j.. stopped

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 9495

Or the bolt port if you like.

$ ineo set-port -b my_db 9496

Installing a specific version

The command create always uses the latest Neo4j version your current Ineo version was tested with. However, it is possible to specify another version using the option -v

ineo create -v 3.2.0 my_db

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

If you happen to use an OS with systemd support, you can also add Ineo as a systemd service to automatically start up you instances on boot.

$ ineo install -S

Installing in a specific directory

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

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

If you are installing from curl:

$ curl -sSL https://raw.githubusercontent.com/cohesivestack/ineo/v2.1.0/ineo | bash -s install -d ~/.ineo-custom-path
