I'm trying to use the following tool to load data from a MySQL (MariaDB, technically) database into Neo4j (both running on same Centos 7 Linux Machine).
https://github.com/neo4j-contrib/neo4j-etl
I've got it downloaded and I've got a root user on the MySQL database with privileges granted across all databases/schemas.
Because I'm using MySQL, I shouldn't need to manually load and configure a JDBC (according to the link above, it is built-in to the latest version of the Neo4j-ETL software).
I'm executing the following command to try and run the executable (as root user):
./neo4j-etl export --rdbms:url jdbc:mysql://localhost:3306 --rdbms:user root --rdbms:password password --destination /var/lib/neo4j/data/new_databases/graph.db --import-tool /usr/bin/ --csv-directory /var/lib/neo4j/import --debug
This command results in the following messages:
INFO: Skipping reading import options from file because file [] doesn't exist.
FINE: Connecting to database...
SEVERE: Could not connect to the host database. Please check your credentials
java.sql.SQLException: The server time zone value 'EDT' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

It seems 'java' command is not available.
Please check your JAVA_HOME environment variable.
Also check if you have a valid Java 8 environment
When I run 'java -version', I get the following, which leads me to believe that my java is okay, despite the error messages:
[root#NEO42 bin]# java -version
openjdk version "1.8.0_222"
OpenJDK Runtime Environment (build 1.8.0_222-b10)
OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)
Both the Neo4j database and the MySQL database live on the server which I'm executing from (localhost). I've tried creating another user in MySQL (which I also granted all privileges for) but when executing the command, I receive the same errors.
Does anyone have any ideas on what my problem could be here? Any tips, suggestions or pointers would be much appreciated.
Figured out where I went wrong. I was specifying the wrong path for the import tool and in the connection URL, I needed to specify the database requested for extraction and import and also needed to specify timezone. Look at the command below for the changes:
./neo4j-etl export --rdbms:url jdbc:mysql://localhost:3306/db?serverTimezone=EST --rdbms:user root --rdbms:password password --destination /var/lib/neo4j/data/new_databases/graph.db --import-tool /usr/share/neo4j/bin/ --csv-directory /var/lib/neo4j/import --debug
Unfortunately, while this mainly answers my question here, there another issue and it seems like it might be a version incompatibility issue, specifically the error I'm seeing is below:
Input error: Missing argument 'into'

I eventually solved the question. It turns out that the DB Version to be used cannot be MySQL 5 as I was specifying. I need to use MariaDB instead. Problem solved ;)
At the moment I am trying to follow this documentation in order to connect to my Second Generation Cloud SQL database. However, my application fails on startup since it cannot connect to it ..
As been told by the documentation, I have added both service accounts
my-project#appspot.gserviceaccount.com
1234-compute#developer.gserviceaccount.com
as Editor under IAM.
I am using the IPv4 of the Cloud SQL instance to connect. Here the connection string:
jdbc:mysql://w.x.y.z:3306/app_db?useSSL=false
but in the Stackdriver Logging view I see:
[main] ERROR com.mz.server.BootstrappingServerConfig - Error trying to migrate SQL scripts ..

Both instances are in the same region: us-central1-b for the compute instances and us-central1 for the SQL instances.
My app.yaml file:
runtime: java
vm: true
runtime_config:
jdk: openjdk8
server: jetty9
env_variables:
'ALPN_ENABLE': 'true' # OPTIONAL
beta_settings:
cloud_sql_instances: mz-test:us-central1:mz-test-cloudsql
health_check:
enable_health_check: false
I am not sure what's wrong here. Am I actually allowed to use the local IPv4 address of the SQL instance?
The documentation actually says
"In your application code, connect to the instance by opening a socket with the following name: /cloudsql/[INSTANCE_CONNECTION_NAME}"
But I am not sure what that would mean for the connection string.
I am also missing the information about what username/password is required or do I not need one here?
Why am I not able to connect?
For Java applications running on App Engine Flexible Environment applications use the following library: https://github.com/GoogleCloudPlatform/cloud-sql-mysql-socket-factory
I have a xampp server running on a AWS-EC2 Ubuntu instance, and I have a database there that is called "androiddb". I can access the database by writing in a navigator http://public_ip/phpmyadmin and entering with "root" user and no password.
In another side I have a Java application that needs to connect with that database, and I have the following line in my code to do it:
con = DriverManager.getConnection("jdbc:mysql://public_ip/androiddb",
"root", "");
When I run my application, I get the following error:

Also I looked for the port where mysql was running and I used the code:
SHOW VARIABLES
WHERE Variable_name IN (
'hostname',
'port')
I write this piece of code in phpmyadmin in the SQL section, and I get the following output:
Variable_name Value
hostname ip-172-31-23-224
port 0
I don't know what does port 0 mean, it should be 3306 (default mysql port)...
Anyways, I don't know if I'm doing something wrong with the xampp configuration or if it's problem of AWS or anything else.
Could someone help me with this? Thank you very much.
You should ensure your security groups for AWS are open on the 3306 port (or whatever you configure) so they can access the database.
You could trouble shoot by trying to SSH into the machine, can you connect locally? If yes, then look at your security groups and open the port. If you can't connect locally than the database is down and you need to diagnose and configure the DB correctly.
But a connection refused is more than likely a port not being open in the security group.
Just to add what solved his issue:
He checked his security groups and opened the correct ports
Checked locally to see that mySQL wasn't listening on any port
netstat -tlnp to check to see SQL running locally
Checked the my.ini file to see that mysql was configured to listen on a port
Found it wasn't and reconfigured it to listen
It may help some working with phpMyAdmin and AWS and Amazon's relational database service (RDS) to know that phpMyAdmin will not work unless the RDS endpoint is edited into the "localhost" or "127.0.0.1" location in the config.inc.php file. (It is a necessary but not sufficient fix -- you may need to do other things...)
Generalizing a bit, if you are using foo and it has a config file, and you are looking to connect to a database instantiated under RDS, you'll need that endpoint as host entry.
I cannot figure out how to access a MySQL database while running in Jenkins CloudBees. I have tried following the Dev#Cloud MySQL, but there are a lot of warnings in the console output and I have to deal with localhost access vs. sockets, which is pretty tricky to debug without a command line.
Is there a way to use the CloudBees MySQL hosting? When I try and use the cloudbees JDBC driver, I get ClassNotFound error messages.
Update: The answer below clarified that I cannot use the CloudBees driver, so I am now using the regular MySQL connector through the c3p0 connection pool. Based on comments below, I have limited the number of connections in the pool to 10.
The exact same configuration and Maven command line works when I run it from my development computer, connecting to the Cloudbees Mysql instance.
Unfortunately, I get this error when trying to connect:

You can't use CloudBees JDBC driver from outside the RUN#Cloud container, but you can use a standard MySQL JDBC driver with your RUN database using the host name and port that you can find on RUN#Cloud web console for your DB resource.
