Hi LiuWenlong,

the table creation seems to fail:

15:22:19,660 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (ServerService Thread Pool -- 64) HHH000388: Unsuccessful: create table ra_ent_group (groupName varchar(255) not null, assignToNewUsers boolean not null, description varchar(255), mirror boolean, singleton boolean not null, special boolean not null, primary key (groupName))

due to

Specified key was too long; max key length is 767 bytes

What DB version are you using? I guess MySQL 5.6 in combination with utf8mb4 encoding? Sadly this configuration will not work out of the box. The best way to overcome this limit would be to use the latest MySQL 5.7 Server or to use another encoding.

Hope this helps,
Marcel

Hi!

The RM Server installation changes the following things:
- RapidMiner Server installation directory
- RapidMiner Server home directory

If you installed startup scripts (/etc/init.d, or /etc/systemd/system), remove these.

If you installed job agents in a path of your choosing, also delete these.

You can also delete the backend database in your database server.

Regards,

Balázs

Thanks Marcel and Balázs,

I have reinstalled RM server , and no errors .
but when i startup it, other errors have occurred.

1.the server is trying to connect to an activeMQ server ,but time out , Do I need to start an activeMQ server before I start the RM server ?
2.Some error messages show that some of the tables on mysql don't exist, but I don't see the part of the table in the document, how do I create tables in mysql?

I don't speak english very well, I hope you can understand what I mean.

Hi LiuWenlong,

the server is trying to connect to an activeMQ server ,but time out , Do I need to start an activeMQ server before I start the RM server ?

The ActiveMQ Broker should start automatically with RapidMiner Server. For troubleshooting please upload the server.log file (you can find this one in the log directory of the server home).

Some error messages show that some of the tables on mysql don't exist, but I don't see the part of the table in the document, how do I create tables in mysql?

This messages should only appear during the first start of RapidMiner Server and indicate the creation of the tables. So, no manual steps required on your end.

Cheers,

Marcel

thanks Marcel,

i upload my server.log and RMS_installer.xml ，Some of RMS_installer.xml been hidden by me.

now i installed RM server ,but when i trying to start is, The startup script stays at the server.log display,
The startup script stays at the server.log display, and i can`t access myhost:8080 .

i trying to access myhost:9990 ,i see 'Welcome to JBoss EAP 6' , Looks like the jBoos server is already started.

and here's the tables that mysql automatically created.
I can't find the tables that appear in the error log in the database.

Hi Izu, i have the exact same Error like you. what do you mean with "changing the endocding to GBK"?

Kind regards

aschaferdiek

Hi. You can change/set the encoding of a database/schema of MySQL. GBK is the encoding for simplified chinese. In general it's advised that you use an up-to-date MySQL version which is supported and the UTF8 encoding.

Could you also provide your server.log file so we can see more details?
