$ git clone https://github.com/milvus-io/milvus.git
```

2. Install third-party dependencies:

```
$ cd milvus

$ cd /home/$USER/milvus
./bin/milvus run standalone    > /tmp/standalone.log     2>&1  &
```

- For Milvus Cluster:

```
$ cd /home/$USER/milvus
#start RootCoord
./bin/milvus run rootcoord     > /tmp/rootcoord.log      2>&1  &
#start coord
./bin/milvus run datacoord     > /tmp/datacoord.log      2>&1  &
./bin/milvus run indexcoord    > /tmp/indexcoord.log     2>&1  &
./bin/milvus run querycoord    > /tmp/querycoord.log     2>&1  &
#start node
./bin/milvus run proxy         > /tmp/proxy.log          2>&1  &
./bin/milvus run datanode      > /tmp/data_node.log      2>&1  &
./bin/milvus run indexnode     > /tmp/index_node.log     2>&1  &
./bin/milvus run querynode     > /tmp/query_node.log     2>&1  &
```
