Start obshell

This topic describes how to start an obshell process by using obshell-sdk-python.

Considerations

Before you start obshell, make sure that obshell is installed in the working directories of all nodes. You can manually download an RPM package and decompress and install it, or you can use obshell-sdk-python to initialize the nodes. During the initialization, obshell is installed. For more information about how to initialize the nodes by using obshell-sdk-python, see Initialize nodes.

Sample code

from obshell import start_obshell, NodeConfig

def init_nodes():
    ips = [
        "10.10.10.1",
        "10.10.10.2",
        "10.10.10.3",
    ]
    work_dir = "/data/ob" # The working directory of OceanBase Database.
    nodes_config = []
    for _, ip in enumerate(ips):
        node = NodeConfig(ip, work_dir)
        nodes_config.append(node)

    # Start obshell.
    start_obshell(nodes_config)
