Tungsten Replicator is available in a number of different distribution types, and
the methods for configuration available for these different packages
differs. See Section 9.1, “Comparing Staging and INI
tpm Methods” for more
information on the available installation methods.
| Deployment Type/Package | TAR/GZip | RPM |
|---|---|---|
| Staging Installation | Yes | No |
| INI File Configuration | Yes | Yes |
| Deploy Entire Cluster | Yes | No |
| Deploy Per Machine | Yes | Yes |
Two primary deployment sources are available:
Using the TAR/GZip package creates a local directory that enables you to perform installs and updates from the extracted 'staging' directory, or use the INI file format.
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-7.1.4-10.tar.gz
The version number is
7.1.4 and build
number 10. Build
numbers indicate which build a particular release version is based on, and
may be useful when installing patches provided by support.
To use the TAR/GZipped packages, download the files to your machine and unpack them:
shell>cd /opt/continuent/softwareshell>tar zxf tungsten-replicator-7.1.4-10.tar.gz
This will create a directory matching the downloaded package name,
version, and build number from which you can perform an install using
either the INI file or command-line configuration. To use, you will need
to use the tpm command within the
tools directory of the extracted package:
shell> cd tungsten-replicator-7.1.4-10The RPM packages can be used for installation, but are primarily designed to be in combination with the INI configuration file.
Installation
Installing the RPM package will do the following:
Create the tungsten system user
if it doesn't exist
Make the tungsten system user
part of the mysql group if it
exists
Create the
/opt/continuent/software
directory
Unpack the software into
/opt/continuent/software
Define the $CONTINUENT_PROFILES and
$REPLICATOR_PROFILES environment variables
Update the profile script to include the
/opt/continuent/share/env.sh script
Create the /etc/tungsten directory
Run tpm install if the
/etc/tungsten.ini or
/etc/tungsten/tungsten.ini file exists
Although the RPM packages complete a number of the pre-requisite steps required to configure your cluster, there are additional steps, such as configuring ssh, that you still need to complete. For more information, see Appendix B, Prerequisites.
By using the package files you are able to setup a new server by creating
the /etc/tungsten.ini file and then installing the
package. Any output from the tpm command will go to
/opt/continuent/service_logs/rpm.output.
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-continuentFor Ubuntu/Debian platforms, the gpg command is used :
root-shell> gpg --keyserver keyserver.ubuntu.com --recv-key 7206c924Once an INI file has been created and the packages are available, the installation can be completed using:
On RHEL/CentOS/Amazon Linux:
root-shell> yum install tungsten-replicatorOn Ubuntu/Debian:
root-shell> apt-get install tungsten-replicatorUpgrades
If you upgrade to a new version of the RPM package it will do the following:
Unpack the software into
/opt/continuent/software
Run tpm update if the
/etc/tungsten.ini or
/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.
