Tungsten Replicator

Deployment Sources

The following primary deployment sources are available:

  • Tar/GZip packages: Using the TAR/GZip package creates a local directory that enables you to perform installs and updates from the extracted 'staging' directory.

  • RPM Packages: Using the RPM package format is more suited to using the INI file format, as hosts can be installed and upgraded to the latest RPM package independently of each other.

All packages are named according to the product, version number, build release and extension. For example:

tungsten-replicator-8.0.4-132.tar.gz

The version number is 8.0.4 and build number 132. Build numbers indicate which build a particular release version is based on, and may be useful when installing patches provided by support.

Using the TAR/GZipped files​

To use the TAR/GZipped packages, download the files to your machine and unpack them:

shell> cd /opt/continuent/software
shell> tar zxf tungsten-replicator-8.0.4-132.tar.gz

This will create a directory matching the downloaded package name, version, and build number from which you can perform an install. To use, you will need to use the tpm command within the tools directory of the extracted package:

shell> cd /opt/continuent/software/tungsten-replicator-8.0.4-132
shell> tools/tpm install

Using the RPM package files​

Installation

Installing the RPM package will do the following:

  1. Create the tungsten system user if it doesn't exist.
  2. Make the tungsten system user part of the mysql group if it exists.
  3. Create the /opt/continuent/software directory.
  4. Unpack the software into /opt/continuent/software
  5. Define the $CONTINUENT_PROFILES and $REPLICATOR_PROFILES environment variables
  6. Update the profile script to include the /opt/continuent/share/env.sh script
  7. Create the /etc/tungsten directory if it doesn't exist
  8. Run tpm install if the /etc/tungsten/tungsten.ini file exists.

If no /etc/tungsten/tungsten.ini was found, then after creation you will need to manually install the software, using the following steps as an example:

shell> cd /opt/continuent/software/tungsten-replicator-8.0.4-132
shell> tools/tpm install

Although the RPM packages complete a number of the prerequisite steps required to configure your cluster, there are additional steps, such as configuring ssh, that you still need to complete. For more information, see "Installation Prerequisites".

By using the package files you are able to set up a new server by creating the /etc/tungsten/tungsten.ini file and then installing the package. Any output from the tpm command will go to /opt/continuent/service_logs/rpm.output.

note

If you download the package files directly, you may need to add the signing key to your environment before the package will load properly.

For yum platforms (RHEL/CentOS/Amazon Linux), the rpm command is used:

root-shell> rpm --import http://www.continuent.com/RPM-GPG-KEY-continuent

For Ubuntu/Debian platforms, the gpg command is used:

root-shell> gpg --keyserver keyserver.ubuntu.com --recv-key 7206c924

Upgrades

If you upgrade to a new version of the RPM package it will do the following:

  1. Unpack the software into /opt/continuent/software
  2. Run tools/tpm update --replace-release if the /etc/tungsten/tungsten.ini file exists.

The tpm update will restart all Continuent Tungsten services so you do not need to do anything after upgrading the package file.
