Running Milvus

After the Milvus database is compiled and installed, prepare the running of Milvus.

  1. Activate the Python virtual environment.
    1
    conda activate milvus
  2. Start etcd.

    You can adjust the etcd data directory as required.

    1
    etcd --data-dir=/data/milvus/data/etcd-data/ &

    The startup is successful if the following information is displayed:

    • To use a script to start or stop Milvus, you can go to the Milvus installation directory first, and the script identifies the current directory. Then, the script enables features such as jemalloc. Entering other directories may cause Milvus startup failure.
    • To disable Milvus, run the following command:
      1
      ~/milvus/scripts/stop.sh
