Uninstalling OKA

To uninstall OKA:

Stop and disable and then remove OKA services:

sudo systemctl stop oka.service
sudo systemctl disable oka.service
sudo systemctl disable okaserver.service
sudo systemctl disable okacelerybeat.service
sudo systemctl disable okacelery_default_queue.service
sudo systemctl disable okacelery_monitoring_queue.service
sudo systemctl disable okacelery_training_queue.service
sudo rm /etc/systemd/system/oka*.service

Delete the OKA directory:
```
sudo rm -rf ${OKA_INSTALL_DIR}
```

Delete the oka_db PostgreSQL database:

sudo -i -u postgres
    psql
        DROP DATABASE oka_db;
        ctrl+d
    ctrl+d

Delete each index generated by OKA in the Elasticsearch database:
```
curl -XDELETE host:port/INDEX_ID
```
If your Elasticsearch db is dedicated to OKA then delete all at once:
```
curl -XDELETE host:port/_all
```
