0. 三台装有CentOS7.8系统的虚拟机，IP如下：

192.168.80.128 # master
192.168.80.129 # slav1
192.168.80.130 # slav2
1. 在三台机器上安装nebula graoh 2.0.0

wget https://oss-cdn.nebula-graph.com.cn/package/2.0.0/nebula-graph-2.0.0.el7.x86_64.rpm

3. 进入配置文件目录，修改权限

cd /usr/local
sudo chown -R syy:syy nebula
cd nebula/etc

4. 配置nebula-metad.conf
修改meta_server_addrs和local_ip两个字段，其他使用默认字段

########## networking ##########
# Comma separated Meta Server addresses
--meta_server_addrs=192.168.80.128:9559,192.168.80.129:9559,192.168.80.130:9559
# Local IP used to identify the nebula-metad process.
# Change it to an address other than loopback if the service is distributed or
# will be accessed remotely.
--local_ip=192.168.80.128
# Meta daemon listening port
--port=9559

7. 修改另外两台机器的配置文件
修改local_ip位对应机器的IP地址
如果修改了配置文件，希望新配置生效，请在配置文件开头添加--local_config=true再重启服务，否则会从缓存中读取过期配置。

8. 启动集群
master:

/usr/local/nebula/scripts/nebula.service start all

slav1和slav2:

/usr/local/nebula/scripts/nebula.service start metad
/usr/local/nebula/scripts/nebula.service start storaged
