单物理机配置3节点是否可行

问答 问题

  • nebula 版本：2.0.0
  • 部署方式（分布式 / 单机 / Docker / DBaaS）：单机3节点，3metad 3graphd 3storaged
    想在单机配置部署3节点集群 ，即3metad 3graphd 3storaged

node1

########## networking ##########
# Comma separated Meta Server addresses
--meta_server_addrs=127.0.0.1:9559,127.0.0.1:9569,127.0.0.1:9579
# 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=127.0.0.1
# Meta daemon listening port
--port=9559
# HTTP service ip
--ws_ip=0.0.0.0
# HTTP service port
--ws_http_port=19559
# HTTP2 service port
--ws_h2_port=19560

node2

metad三个节点的IP是否可以为1287.0.0.1+不同端口号区分？
通过指定三个 节点metad的conf，端口不一样，启动，然后报错

# ! /bin/sh
#start 3 metad nodes
./nebula.sevice  -c /lab/nebula-graph/etc/node1/nebula-metad.conf start metad 
./nebula.sevice  -c /lab/nebula-graph/etc/node2/nebula-metad.conf start metad 
./nebula.sevice  -c /lab/nebula-graph/etc/node3/nebula-metad.conf start metad

单机不使用docker是否可以部署多个节点运行？多谢

你可以拷贝三份安装目录，然后再去修改安装目录里面的配置文件，而不是在脚本里面去启动三次同个目录下面的binary。

懂了，本来想偷懒，这样目录有些文件如pid有依赖，不能这么做。3Q~
