Ambari-server 2.7.3.0-139 setup doesn't work as expected

moritz — Mon, 09 Sep 2019 21:26:55 GMT

The non-interactive setup of Ambari seems to be broken. It looks like the /etc/ambari-server/conf/ambari.properties file is not updated when using the ambari-server setup CLI flags (non-interactive setup).

Has anyone ever had the same issue?

Environment

CentOS Linux release 7.6.1810 (Core)
http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.3.0 repo for ambari-server

Steps to reproduce

sudo yum install -y postgresql-jdbc ambari-server
sudo ambari-server setup --help

Using python /usr/bin/python
Setup ambari-server
Usage: ambari-server.py action [options]

Options:
-h, --help show this help message and exit
-v, --verbose Print verbose status messages
-s, --silent Silently accepts default prompt values. For db-cleanup
command, silent mode will stop ambari server.

--jdbc-db=JDBC_DB Specifies the database type
[postgres|mysql|mssql|oracle|hsqldb|sqlanywhere] for
the JDBC driver specified with the --jdbc-driver
option. Used only with --jdbc-driver option.

Other options:

@moritz

By running the following command , you are telling Ambari to use an Existing Postgres DB instance in this case ambari will expect you to create the Db user and setup the DB schema on your own inside the PostgresDB (ambari will not do it for you).

# sudo ambari-server setup --java-home /usr/lib/jvm/java-1.8.0-openjdk/jre --enable-lzo-under-gpl-license --database=postgres --databasehost=localhost --databaseport=5432 --databasename=ambari --postgresschema=ambari --databaseusername=ambari --databasepassword=ambari --jdbc-db=postgres --jdbc-driver=/usr/share/java/postgresql-jdbc.jar

Using existing Postgres DB instance for Ambari DB means we will need to make sure that After running the above "setup" command and before running the "start" command you already have performed the following task on your Postgres Database explicitly.

https://docs.cloudera.com/HDPDocuments/Ambari-2.7.3.0/administering-ambari/content/amb_using_ambari_with_postgresql.html

Are you sure that before starting Ambari DB you had performed the instructions mentioned in the above link?

If you want Ambari to setup the PostgresDB (create DB user/ create various tables ..etc) for you then you may want to run the setup command without specifying the Postgres DB details so that ambari will think that it has to setup the Postgres DB for you in the Localhost with default settings like. default ambari DB username will be "ambari" default Postgres Db password will. be "bigdata" ...etc

# sudo ambari-server setup --java-home /usr/lib/jvm/java-1.8.0-openjdk/jre --enable-lzo-under-gpl-license -s

you can give like this , if you want to use the embedded postgresql database of ambari .

sudo ambari-server setup --java-home /usr/lib/jvm/java-1.8.0-openjdk/jre --enable-lzo-under-gpl-license --database=embedded

Thanks for your answers @akhilsnaik and @jsensharma.

I forgot to mention it but I am using a database created by following the documentation mentioned by jsensharma.

I already tried to use the embedded database by only using the --silent flag and it works, but in my case, I want a separate database. After installing it, I have created the ambari user, database and schema and I have loaded the /var/lib/ambari-server/resources/Ambari-DDL-Postgres-CREATE.sql script with no warning or error.

Thanks

Thomas

I see in your "ambari.properties" there are no JDBC settings appeared because looks like you are mixing the custom driver setup arguments along with the JDBC DB setup arguments in a single setup commands. Thats the reason the JDBC settings are not getting persisted.

Please try the following sequence of setup.

Step-1). Setup the JDBC DB settings. After this step you should see that your ambari.properties file has the JDBC entries in it.

# ambari-server setup --java-home /usr/lib/jvm/java-1.8.0-openjdk/jre --enable-lzo-under-gpl-license --database=postgres --databasehost=localhost --databaseport=5432 --databasename=ambari --databaseusername=ambari --postgresschema=ambari --databasepassword=ambari -s

Step-2). Now Setup the Custom Postgres JDBC Driver of your own choice using the following command. However, usually ambari ships a Postgres Driver here "/usr/lib/ambari-server/postgresql-*"

# ambari-server setup --jdbc-db=postgres --jdbc-driver=/usr/share/java/postgresql-jdbc.jar

Step-3). Now run the following command to verify the JDBC settings are reflected properly or not?

Example:

# grep 'jdbc' /etc/ambari-server/conf/ambari.properties custom.postgres.jdbc.name=postgresql-jdbc.jar server.jdbc.connection-pool=internal server.jdbc.database=postgres server.jdbc.database_name=ambari server.jdbc.driver=org.postgresql.Driver server.jdbc.hostname=localhost server.jdbc.port=5432 server.jdbc.postgres.schema=ambari server.jdbc.rca.driver=org.postgresql.Driver server.jdbc.rca.url=jdbc:postgresql://localhost:5432/ambari server.jdbc.rca.user.name=ambari server.jdbc.rca.user.passwd=/etc/ambari-server/conf/password.dat server.jdbc.url=jdbc:postgresql://localhost:5432/ambari server.jdbc.user.name=ambari server.jdbc.user.passwd=/etc/ambari-server/conf/password.dat

Thanks a lot for your answer @jsensharma, using your command makes everything work as expected!

I didn't try this before because I was a bit confused about the impact of the --silent flag. I was assuming (wrongly) that using --silent implied to have all the parameters set to their default values.
