管理Nebula Graph服务

    nebula.service的默认路径是/usr/local/nebula/scripts，如果修改过安装路径，请使用实际路径。

    对于使用RPM或DEB文件安装的Nebula Graph，执行如下命令启动服务：

    1. $ sudo /usr/local/nebula/scripts/nebula.service start all
    2. [INFO] Starting nebula-metad...
    3. [INFO] Done
    4. [INFO] Starting nebula-graphd...
    5. [INFO] Done
    6. [INFO] Starting nebula-storaged...
    7. [INFO] Done

    容器部署

    对于使用Docker Compose部署的Nebula Graph，在nebula-docker-compose/目录内执行如下命令启动服务：

    1. [nebula-docker-compose]$ docker-compose up -d
    2. Building with native build. Learn about native build in Compose here: https://docs.docker.com/go/compose-native-build/
    3. Creating network "nebula-docker-compose_nebula-net" with the default driver
    4. Creating nebula-docker-compose_metad0_1 ... done
    5. Creating nebula-docker-compose_metad2_1 ... done
    6. Creating nebula-docker-compose_metad1_1 ... done
    7. Creating nebula-docker-compose_graphd1_1   ... done
    8. Creating nebula-docker-compose_storaged1_1 ... done
    9. Creating nebula-docker-compose_storaged0_1 ... done
    10. Creating nebula-docker-compose_graphd2_1   ... done
    11. Creating nebula-docker-compose_graphd_1    ... done

    Danger

    请勿使用kill -9 命令强制终止进程，否则可能较小概率出现数据丢失。

    容器部署

    在nebula-docker-compose/目录内执行如下命令停止Nebula Graph服务：

    1. nebula-docker-compose]$ docker-compose down
    2. Stopping nebula-docker-compose_graphd_1    ... done
    3. Stopping nebula-docker-compose_graphd2_1   ... done
    4. Stopping nebula-docker-compose_storaged0_1 ... done
    5. Stopping nebula-docker-compose_storaged1_1 ... done
    6. Stopping nebula-docker-compose_graphd1_1   ... done
    7. Stopping nebula-docker-compose_storaged2_1 ... done
    8. Stopping nebula-docker-compose_metad1_1    ... done
    9. Stopping nebula-docker-compose_metad2_1    ... done
    10. Stopping nebula-docker-compose_metad0_1    ... done
    11. Removing nebula-docker-compose_graphd_1    ... done
    12. Removing nebula-docker-compose_graphd2_1   ... done
    13. Removing nebula-docker-compose_storaged0_1 ... done
    14. Removing nebula-docker-compose_storaged1_1 ... done
    15. Removing nebula-docker-compose_graphd1_1   ... done
    16. Removing nebula-docker-compose_storaged2_1 ... done
    17. Removing nebula-docker-compose_metad1_1    ... done
    18. Removing nebula-docker-compose_metad2_1    ... done
    19. Removing nebula-docker-compose_metad0_1    ... done

    Note

    命令docker-compose down -v将会删除所有本地Nebula Graph的数据。如果使用的是developing或nightly版本，并且有一些兼容性问题，请尝试这个命令。

    执行如下命令查看Nebula Graph服务状态：

    • 如果返回如下结果，表示Nebula Graph服务正常运行。

      1. [INFO] nebula-metad: Running as 25600, Listening on 9559
      2. [INFO] nebula-graphd: Exited
      3. [INFO] nebula-storaged: Running as 25646, Listening on 9779

    Nebula Graph服务由Meta服务、Graph服务和Storage服务共同提供，这三种服务的配置文件都保存在安装目录的etc目录内，默认路径为/usr/local/nebula/etc/，用户可以检查相应的配置文件排查问题。

    容器部署

    在nebula-docker-compose目录内执行如下命令查看Nebula Graph服务状态：

    1. nebula-docker-compose]$ docker-compose ps
    2.             Name                             Command                  State                                             Ports

    如果服务有异常，用户可以先确认异常的容器名称（例如nebula-docker-compose_graphd2_1）,

    然后执行docker ps查看对应的CONTAINER ID(示例为2a6c56c405f5)。

    最后登录容器排查问题

    1. [root@2a6c56c405f5 nebula]#
