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.
- Bash. Installed by default on OS X and Ubuntu
- Curl. Installed by default on OS X and Ubuntu
- Java 1.8+. In order to start the Neo4j server
-
Execute the line bellow on your terminal:
curl -sSL http://getineo.cohesivestack.com | bash -s install -
Restart your terminal or execute the line bellow:
source ~/.bashrc
Imagine that you need a database for an application called my_db:
$ ineo create my_db
The instance my_db was created successfully
Show the information about the recently instance created:
$ ineo instances
> instance 'my_db'
VERSION: 3.3.1
PATH: /home_path/.ineo/instances/my_db
PORT: 7474
HTTPS: 7473
BOLT: 7687
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 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 the status of the database instance
$ ineo status my_db
status 'my_db'
Neo4j Server is running at pid 19773
Stop the database instance
$ ineo stop my_db
stop 'my_db'
Stopping Neo4j.. stopped
It's also possible to restart a database instance
$ ineo restart my_db
The main objetive of Ineo is managing different Neo4j instances.
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: 3.3.1
PATH: /home_path/.ineo/instances/my_db
PORT: 7474
HTTPS: 7475
BOLT: 7687
> instance 'my_db_test'
VERSION: 3.3.1
PATH: /home_path/.ineo/instances/my_db_test
PORT: 8486
HTTPS: 8487
BOLT: 7687
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.
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
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
It's also possible to restart multiple instances using the command restart without instance name.
$ ineo restart
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
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 3.2.0
The command versions shows all Neo4j versions available for installing.
$ ineo versions
There is a command to install Ineo. Use this command only if you don't have already installed Ineo.
$ ineo install
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
Just typing ineo you can get a brief description of every Ineo command.
