使用 RPM/DEB 包部署 NebulaGraph 多机集群¶
本文介绍通过 RPM 或 DEB 文件部署集群的示例。
Note
用户还可以通过官方工具部署 NebulaGraph 多机集群。详情参见使用生态工具安装集群。
部署方案¶
机器名称 | IP 地址 | graphd 进程数量 | storaged 进程数量 | metad 进程数量 |
---|---|---|---|---|
A | 192.168.10.111 | 1 | 1 | 1 |
B | 192.168.10.112 | 1 | 1 | 1 |
C | 192.168.10.113 | 1 | 1 | 1 |
D | 192.168.10.114 | 1 | 1 | - |
E | 192.168.10.115 | 1 | 1 | - |
前提条件¶
- 准备 5 台用于部署集群的机器。
- 在集群中通过 NTP 服务同步时间。
手动部署流程¶
安装 NebulaGraph¶
在集群的每一台服务器上都安装 NebulaGraph,安装后暂不需要启动服务。安装方式请参见:
(企业版)设置 License。¶
如果部署企业版 NebulaGraph,需要设置 License。详情请参见设置 NebulaGraph 企业版 License。
修改配置文件¶
修改每个服务器上的 NebulaGraph 配置文件。
NebulaGraph 的所有配置文件均位于安装目录的etc
目录内,包括nebula-graphd.conf
、nebula-metad.conf
和nebula-storaged.conf
,用户可以只修改所需服务的配置文件。各个机器需要修改的配置文件如下。
机器名称 | 待修改配置文件 |
---|---|
A | nebula-graphd.conf 、nebula-storaged.conf 、nebula-metad.conf |
B | nebula-graphd.conf 、nebula-storaged.conf 、nebula-metad.conf |
C | nebula-graphd.conf 、nebula-storaged.conf 、nebula-metad.conf |
D | nebula-graphd.conf 、nebula-storaged.conf |
E | nebula-graphd.conf 、nebula-storaged.conf |
用户可以参考如下配置文件的内容,仅展示集群通信的部分设置,未展示的内容为默认设置,便于用户了解集群间各个服务器的关系。
Note
主要修改的配置是meta_server_addrs
,所有配置文件都需要填写所有 Meta 服务的 IP 地址和端口,同时需要修改local_ip
为机器本身的联网 IP 地址。配置参数的详细说明请参见:

启动集群¶
依次启动各个服务器上的对应进程。
机器名称 | 待启动的进程 |
---|---|
A | graphd、storaged、metad |
B | graphd、storaged、metad |
C | graphd、storaged、metad |
D | graphd、storaged |
E | graphd、storaged |
启动 NebulaGraph 进程的命令如下:
sudo /usr/local/nebula/scripts/nebula.service start <metad|graphd|storaged|all>
Note
- 确保每个服务器中的对应进程都已启动,否则服务将启动失败。
- 当需都启动 graphd、storaged 和 metad 时,可以用 all 代替。
/usr/local/nebula
是 NebulaGraph 的默认安装路径,如果修改过安装路径,请使用实际路径。更多启停服务的内容,请参见管理 NebulaGraph 服务。
检查集群¶
安装原生 CLI 客户端 NebulaGraph Console,然后连接任何一个已启动 graphd 进程的机器,添加 Storage 主机,然后执行命令SHOW HOSTS
检查集群状态。例如:
$ ./nebula-console --addr 192.168.10.111 --port 9669 -u root -p nebula
2021/05/25 01:41:19 [INFO] connection pool is initialized successfully
