Roughtly the same as you would do locally but using a single console prompt.

E.g. run server processes in background like https://travis-ci.community/t/running-docker-containers-in-parallel-with-tests/7046:

install:
  - /path/to/server1 args & PIDS="$!"       # a service may provide some other way to know its PID like a pidfile
  - /path/to/server2 args & PIDS="$PIDS $!"
script:
  - <run tests>
after_script:
  - kill $PIDS    # or shut down servers gracefully in some other service-specific way
  - wait $PIDS    # likewise, a service may provide some other way to wait for its shutdown
