OPENNMS detaching a database

1. Detaching a Database 1.1 configuration OpenNMS file

1. We need to modify the DataSource data source in OpenNMS, in the following directory in OPENNMS:

/opt/opennms/etc/opennms-datasources.xml

2. Change localhost to the database host IP address

<jdbc-data-source name= "OpenNMS"                      database-name= "OpenNMS"                      class-name= " Org.postgresql.Driver "                      url= "jdbc:postgresql://database host Ip:5432/opennms"                      user-name= "OpenNMS"                      password= "OpenNMS"/

Before modification:

After modification:

1.2 Installing the PostgreSQL database

1. Installing the PostgreSQL database

Yum install PostgreSQL postgresql-server command, the system automatically download PostgreSQL installation.

2. Start PostgreSQL First

Run the command as root:

/sbin/service PostgreSQL Start

3. If you see an error, you must initialize PostgreSQL and run the following command:

/sbin/service PostgreSQL Initdb

/sbin/service PostgreSQL Start

4. To ensure that PostgreSQL will start after a restart, use the "chkconfig" command to start at startup and run the following command:

/sbin/chkconfig PostgreSQL on

1.2.1 Configuration allows user access to the database

1. Find the/var/lib/pgsql/data/pg_hba.conf content:

Ident->trust

Revision changed to

Can.

2. Locate/var/lib/pgsql/data/postgresql.conf to modify the following:

listen_addresses = ' * '

#port = 5432 Remove the "#" number

3. After the modification, you need to restart the database to run as root:

/sbin/service PostgreSQL Restart

1.3 Testing

Testing the PostgreSQL database on a detached host in a OPENNMS host

1. Log in to the OPENNMS host with Putty

2. Execute psql-h Database host IP -u opennms-d opennms

3. View the database

Execute COMMAND \l

View User

Execute Command \du

Exit

Execute Command \q

The above test instructions can be successfully connected on the OPENNMS host to isolate the database

1.4 Execute the SQL statement on the client:

1. Under the/OPT/OPENNMS/ETC directory

Restart OpenNMS after execution is complete
