To start a replica set in MongoDB, you need to configure the members of the set and then initiate it. Here's an example for three members:

1. Create the replica set configuration file (replset.conf) with the following content:

```
rs.initiate({
_id : 'myReplSet',
members: [
{_id: 0, host : 'localhost:27017'},
{_id: 1, host : 'localhost:27018'},
{_id: 2, host : 'localhost:27019'}
]
})
```

2. Start MongoDB with the configuration file:

```
mongod --replSet myReplSet --smallfiles --config replset.conf
```

3. Repeat step 2 for each member of the replica set.
4. Connect to any of the members and check the status of the replica set:

```javascript
rs.status()
```
