Starting and stopping services in WSL environment
First we find whether our environment uses Sysv Init or systemd. The below command will give that
ps -p 1
As an example, we use elasticsearch service
With Sysv init
Use the update-rc.d command to configure Elasticsearch to start automatically when the system boots up
sudo update-rc.d elasticsearch defaults 95 10
Elasticsearch can be started and stopped using the service command:
sudo -i service elasticsearch start
sudo -i service elasticsearch stop
If Elasticsearch fails to start for any reason, it will print the reason for failure to STDOUT. Log files can be found in /var/log/elasticsearch/
With systemd
To configure Elasticsearch to start automatically when the system boots up, run the following commands:
sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service
Elasticsearch can be started and stopped as follows:
sudo systemctl start elasticsearch.service
sudo systemctl stop elasticsearch.service

We can override environment variables in the integrated terminals using the following commands in the settings.json
"terminal.integrated.env.windows": {
"JAVA_HOME": "D:\\Applns\\Java\\amz_jdk11.0.11_9"
}The above command will override JAVA_HOME for the integrated terminal in windows so that we can run maven with separate JAVA_HOME in vscode
