Once you have completed the configuration of the PostgreSQL database, you can configure and install the PostgreSQL applier as described using the steps below.
Unpack the Tungsten Replicator distribution in staging directory:
shell> tar zxf tungsten-replicator-7.1.4-10.tar.gzChange into the staging directory:
shell> cd tungsten-replicator-7.1.4-10Configure the installation using tpm:
shell>./tools/tpm configure defaults \ --reset \ --install-directory=/opt/continuent \ --user=tungsten \ --profile-script=~/.bash_profile \ --rest-api-admin-user=apiuser \ --rest-api-admin-pass=secretshell>./tools/tpm configure alpha \ --master=sourcehost \ --members=localhost,sourcehost \ --datasource-type=postgresql \ --postgresql-dbname=dbname \ --replication-user=tungsten \ --replication-password=secret \ --replication-host=remotedbhost \ --replication-port=5432
shell> vi /etc/tungsten/tungsten.ini[defaults] install-directory=/opt/continuent user=tungsten profile-script=~/.bash_profile rest-api-admin-user=apiuser rest-api-admin-pass=secret[alpha] master=sourcehost members=localhost,sourcehost datasource-type=postgresql postgresql-dbname=dbname replication-user=tungsten replication-password=secret replication-host=remotedbhost replication-port=5432
Configuration group defaults
The description of each of the options is shown below; click the icon to hide this detail:
For staging configurations, deletes all pre-existing configuration information between updating with the new configuration values.
--install-directory=/opt/continuent
install-directory=/opt/continuent
Path to the directory where the active deployment will be installed. The configured directory will contain the software, THL and relay log information unless configured otherwise.
System User
--profile-script=~/.bash_profile
profile-script=~/.bash_profile
Append commands to include env.sh in this profile script
Configuration group alpha
The description of each of the options is shown below; click the icon to hide this detail:
The hostname of the primary (extractor) within the current service.
--members=localhost,sourcehost
Hostnames for the dataservice members
Database type
Name of the database to replicate
For databases that required authentication, the username to use when connecting to the database using the corresponding connection method (native, JDBC, etc.).
The password to be used when connecting to the database using
the corresponding
--replication-user.
--replication-host=remotedbhost
Hostname of the datasource where the database is located. If the specified hostname matches the current host or member name, the database is assumed to be local. If the hostnames do not match, extraction is assumed to be via remote access. For MySQL hosts, this configures a remote replication Replica (relay) connection.
The network port used to connect to the database server. The default port used depends on the database being configured.
If you plan to make full use of the REST API (which is enabled by default) you will need to also configure a username and password for API access. This must be done by specifying the following options in your configuration:
rest-api-admin-user=tungsten rest-api-admin-pass=secret
Once the prerequisites and configuring of the installation has been completed, the software can be installed:
shell> ./tools/tpm install
If the installation process fails, check the output of the
/tmp/tungsten-configure.log file for
more information about the root cause.
Once the replicators have started, the status of the service can be checked using trepctl. See Section 4.8.3, “Management and Monitoring of PostgreSQL Deployments” for more information.
