环境准备

系统

CentOS7.9

机器

三台，分别为nebula01、nebula02、nebula03、

安装位置

/usr/local

nebula版本

2.6.1

nebula-graph-studio版本

3.2.3

快速开始

下载tar.gz文件

cd /usr/local
wget https://oss-cdn.nebula-graph.com.cn/package/2.6.1/nebula-graph-2.6.1.el7.x86_64.tar.gz
wget https://oss-cdn.nebula-graph.com.cn/nebula-graph-studio/3.2.3/nebula-graph-studio-3.2.3.x86_64.tar.gz

解压缩并重命名文件

tar -zxvf nebula-graph-2.6.1.el7.x86_64.tar.gz && mv nebula-graph-2.6.1.el7.x86_64 nebula
tar -zxvf nebula-graph-studio-3.2.3.x86_64.tar.gz && mv nebula-graph-studio-3.2.3.x86_64 nebula-graph-studio

复制配置文件

cd nebula/etc
cp nebula-graphd.conf.default nebula-graphd.conf
cp nebula-metad.conf.default nebula-metad.conf
cp nebula-storaged.conf.default nebula-storaged.conf

修改配置文件

1	vim nebula-graphd.conf

...
# The directory to host logging files
--log_dir=/data/nebula/logs
...
# Comma separated Meta Server Addresses
--meta_server_addrs=nebula01:9559,nebula02:9559,nebula03:9559
# Local IP used to identify the nebula-graphd process.
# Change it to an address other than loopback if the service is distributed or
# will be accessed remotely.
--local_ip=nebula01
...

1	vim nebula-metad.conf

...
# The directory to host logging files
--log_dir=/data/nebula/logs
...
# Comma separated Meta Server addresses
--meta_server_addrs=nebula01:9559,nebula02:9559,nebula03:9559
# 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=nebula01
...
# Root data path, here should be only single path for metad
--data_path=/data/nebula/meta
...

1	vim nebula-storaged.conf

...
# The directory to host logging files
--log_dir=/data/nebula/logs
...
# Comma separated Meta server addresses
--meta_server_addrs=nebula01:9559,nebula02:9559,nebula03:9559
# Local IP used to identify the nebula-storaged process.
# Change it to an address other than loopback if the service is distributed or
# will be accessed remotely.
--local_ip=nebula01
...
# Root data path. Split by comma. e.g. --data_path=/disk1/path1/,/disk2/path2/
# One path per Rocksdb instance.
--data_path=/data/nebula/storage
...

分发nebula文件，并修改对应的--local_ip

cd ../..
scp -r nebula nebula02:`pwd`/
scp -r nebula nebula03:`pwd`/

启动集群

注：因为meta机器选择了nebula01、02、03共三台机器，启动时需要将三台同时执行命令拉起

1	nebula/scripts/nebula.service start all

检查集群状态

1	nebula/scripts/nebula.service status all

[INFO] nebula-metad(de03025): Running as 24680, Listening on 9559 
[INFO] nebula-graphd(de03025): Running as 25453, Listening on 9669 
[INFO] nebula-storaged(de03025): Running as 24787, Listening on 9779

此时nebula文件夹下生成cluster.id文件，集群成功启动

启动nebula-graph-studio

1 2	cd nebula-graph-studio nohup ./server &
