Tungsten Replicator

Install MongoDB Applier

note

The steps in this section relate specifically to applying to a standard MongoDB Instance. For configuring the applier to work with MongoDB Atlas, please refer to the following section: "Install MongoDB Atlas Applier"

Installation of the MongoDB replication requires special configuration of the Source and Target hosts so that each is configured for the correct datasource type.

To configure the Applier replicators:

Before installing the applier, the following additions need adding to the extractor configuration. Apply the following parameter to the extractor configuration before installing the applier
Add the following to /etc/tungsten/tungsten.ini
```
[alpha]
...Existing Replicator Config...
enable-heterogeneous-service=true

shell> tpm update
```
Note
The above step is only applicable for standalone extractors. If you are configuring replications from an existing Tungsten Cluster (Cluster-Extractor), follow the steps outlined here to ensure the cluster is configured correctly: "Replicating Data Out of a Cluster"
Unpack the Tungsten Replicator distribution in staging directory:
```
shell> tar zxf tungsten-replicator-8.0.4-132.tar.gz
```
Change into the staging directory:
```
shell> cd tungsten-replicator-8.0.4-132
```
Create the /etc/tungsten/tungsten.ini using the example below as a template.
Example tungsten.ini
```
[defaults]
install-directory=/opt/continuent
profile-script=~/.bash_profile
rest-api-admin-user=apiuser
rest-api-admin-password=secret

rest-api-admin-user=apiuserSpecify the initial Admin Username for API access.Available from v7.0.0
rest-api-admin-password=secretSpecify the initial Admin User Password for API access. rest-api-admin-password alias only available from version 7.1.2 onwards.Available from v7.0.0
replicator-rest-api-address=0.0.0.0Address for the API to bind too.Available from v7.0.0
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 "Management and Monitoring of MongoDB Deployments" for more information.
