Start Percona Link for MongoDB

Start Percona Link for MongoDB.

We recommend to use the packaged service scripts to run plm.

$ sudo systemctl start plm

Check the status with this command:

$ sudo systemctl status plm

You can start PLM manually. This option is the way you start Percona Link for MongoDB if you installed it from source code

Run Percona Link for MongoDB with the following command if you haven’t defined MongoDB connection string URI before:

$ nohup plm --source <source-mongodb-uri> --target <target-mongodb-uri> --no-color > percona-link-mongodb.log 2>&1 &

Alternatively, you can use environment variables:

$ export SOURCE_URI=<source-mongodb-uri>
$ export TARGET_URI=<target-mongodb-uri>
$ nohup plm --no-color > percona-link-mongodb.log 2>&1 &

See Percona Link for MongoDB startup configuration for all available options.

With the packaged systemd service, the log output to stdout is captured by systemd’s default redirection to systemd-journald. You can view it with this command:

$ sudo journalctl -u plm.service

See man journalctl for useful options such as --lines, --follow, etc.

If you started plm manually, see the file you redirected stdout and stderr to.

Next steps

Congratulations! you have successfully installed and connected PLM to your source and target MongoDB. Now you have it up and running and you are ready to use it.
