HugeGraph 安装及试用（hugegraph、hugegraph-studio、hugegraph-hubble、hugegraph-tools、hugegraph-loader）

前置准备

• JDK 环境要配置好

• 创建目录

mkdir -p /boazy/middleware/hugegraph && cd /boazy/middleware/hugegraph

• 配置约定

  rest 服务端口设置为：18080

  gremlin 服务端口设置为：18182

  所有本地实例 host 均设置为：0.0.0.0

hugegraph

首先要进入指定目录

cd /boazy/middleware/hugegraph

我们这里要安装完行 1 个 hugegraph-studio 实例

安装 hugegraph

• 下载 hugegraph

wget https://github.com/hugegraph/hugegraph/releases/download/v0.11.2-b3/hugegraph-0.11.2-b3.tar.gz

• 解压 hugegraph

tar -zxvf hugegraph-0.11.2-b3.tar.gz

结果：

[root@localhost hugegraph]# pwd && ll -h
/boazy/middleware/hugegraph

-rw-r--r--. 1 root root 200M 7月  17 16:26 hugegraph-0.11.2-b3.tar.gz
[root@localhost hugegraph]#

配置 hugegraph

• 配置 rest-server.properties

配置 host 、端口和图实例（这里配置 9 个图实例 gdb01~gdb09）

cd /boazy/middleware/hugegraph/hugegraph-0.11.2 \
&& sed -i "s/restserver.url=http:\/\/127.0.0.1:8080/restserver.url=http:\/\/0.0.0.0:18080/g" conf/rest-server.properties \

[root@centos7-qscft hugegraph-0.11.2]#

• 配置 gremlin-server.yaml

cd /boazy/middleware/hugegraph/hugegraph-0.11.2 \
&& sed -i "s/#host: 127.0.0.1/host: 0.0.0.0/g"  conf/gremlin-server.yaml \

配置图实例配置文件

• 切换到 hugegraph-0.11.2 目录

cd /boazy/middleware/hugegraph/hugegraph-0.11.2

• 复制图实例配置文件（9 个）

for N in 1 2 3 4 5 6 7 8 9
do cp conf/hugegraph.properties conf/gdb0${N}.properties
done

配置防火墙

• 添加端口白名单

for N in 18080 18182
do firewall-cmd --zone=public --add-port=${N}/tcp --permanent
done

• 让端口白名单生效

firewall-cmd --reload && firewall-cmd --zone=public --list-ports

结果：

[root@localhost hugegraph-0.11.2]# firewall-cmd --reload && firewall-cmd --zone=public --list-ports
success

hugegraph-studio

首先要进入指定目录

cd /boazy/middleware/hugegraph

我们这里要安装完行多个 hugegraph-studio 实例

安装 hugegraph-studio

• 下载 hugegraph-studio

wget https://github.com/hugegraph/hugegraph-studio/releases/download/v0.11.0/hugegraph-studio-0.11.0.tar.gz

• 解压 hugegraph-studio

tar -zxvf hugegraph-studio-0.11.0.tar.gz

结果：

[root@localhost hugegraph]# pwd && ll -h
/boazy/middleware/hugegraph
总用量 0

• 复制多个 hugegraph-studio 实例目录

这里要安装 9 个 hugegraph-studio 实例

for N in 1 2 3 4 5 6 7 8 9
do cp -r hugegraph-studio-0.11.0 720${N}-hugegraph-studio-0.11.0
done

配置 hugegraph-studio

• 配置多个 hugegraph-studio 实例的配置信息

for N in 1 2 3 4 5 6 7 8 9
do sed -i "s/studio.server.port=8088/studio.server.port=720${N}/g" 720${N}-hugegraph-studio-0.11.0/conf/hugegraph-studio.properties \
  && sed -i "s/studio.server.host=localhost/studio.server.host=0.0.0.0/g" 720${N}-hugegraph-studio-0.11.0/conf/hugegraph-studio.properties \

  && sed -i "s/graph.name=gdb00/graph.name=gdb0${N}/g" 720${N}-hugegraph-studio-0.11.0/conf/hugegraph-studio.properties
done

• 检查配置信息

for N in 1 2 3 4 5 6 7 8 9
do cat 720${N}-hugegraph-studio-0.11.0/conf/hugegraph-studio.properties |grep ".server." |grep -v ".ui" |grep -v ".api" \

备份与恢复数据

• 要先切换到 hugegraph-tools-1.5.0 目录

cd /boazy/middleware/hugegraph/hugegraph-tools-1.5.0

• 备份

这里演示备份 gdb01~gdb09 实例的数据！

for N in 1 2 3 4 5 6 7 8 9
do bin/hugegraph --graph gdb0${N} --url http://192.168.0.89:18080 backup -t all -d gdb0${N}
done

zip 打包备份

zip -r 720-gdb01-gdb02_$(date +%Y%m%d%H%M%S).zip gdb01 gdb02 gdb03 gdb04 gdb05 gdb06 gdb07 gdb08 gdb09

• 恢复

这里演示将 gdb01~gdb08 实例的备份数据恢复（合并）到 gdb09 实例中！

bin/hugegraph --graph gdb09 --url http://192.168.0.89:18080 graph-mode-set -m MERGING && \
for N in 1 2 3 4 5 6 7 8

数据导入

• 要先切换到 hugegraph-loader-0.11.1 目录

cd /boazy/middleware/hugegraph/hugegraph-loader-0.11.1

• 数据导入

先要将要志入的数据上传到 hugegraph-loader-0.11.1 下然后再执行导入命令

sh bin/hugegraph-loader.sh -g gdb09 -s stcok-data/schema.groovy -f stcok-data/struct.json -h 127.0.0.1 -p -18080

遇到的问题

执行 sh 文件错误

• 执行 sh 文件时出现错误

/bin/bash^M: bad interpreter: No such file or directory

• 解决方法

# 安装 dos2unix
yum -y install dos2unix
# 转换 sh 文件
dos2unix bin/hugegraph-studio.sh

设置开机启动

• 通过配置 /etc/rc.d/rc.local 实现

vi /etc/rc.d/rc.local

内容（根据应用实际情况）如下：

# su - root -c 'systemctl restart network'
su - root -c 'sh /boazy/middleware/hugegraph/hugegraph-0.11.2/bin/start-hugegraph.sh'
su - root -c 'nohup /boazy/middleware/hugegraph/hugegraph-studio-0.11.0/bin/hugegraph-studio.sh &'
su - root -c 'sh /boazy/middleware/hugegraph/hugegraph-hubble-1.5.0/bin/start-hubble.sh'

查路径

• 查最短路径

g.V().hasId('35:严兰')
  .store('x').repeat(both().where(without('x')).aggregate('x'))
  .until(hasId('35:袁宁'))
  .path().limit(1)

• 查单向路径

g.V().hasId('35:严兰')
  .repeat(out().simplePath()).until(hasId('35:袁宁'))
  .path()

• 查双向路径

g.V().hasId('35:严兰')
  .repeat(both().simplePath()).until(hasId('35:袁宁'))
  .path()

• 查路径，出度为 0 截止

g.V()
  .has('中文名',within('小麦滋养保湿洁面乳','欧莱雅(LOREAL)青春密码酵素精华肌底液'))
  .repeat(out()).until(outE().count().is(0))
  .path()

删除点和边

g.E().drop()
g.V().drop()

删除 Label

// 查询所有 indexLabel
graph.schema().getIndexLabels()
// 查询所有 edgeLabel
graph.schema().getEdgeLabels()
// 查询所有 vertexLabel
graph.schema().getVertexLabels()
// 查询所有 propertyKey
graph.schema().getPropertyKeys()

// 删除 indexLabel
graph.schema().indexLabel("personByAge").remove()
// 删除 edgeLabel
graph.schema().edgeLabel("rate").remove()
// 删除 vertexLabel
graph.schema().vertexLabel("person").remove()
// 删除 propertyKey
graph.schema().propertyKey("weight").remove()

测试：

graph.schema().edgeLabel("属于.ee").remove();
graph.schema().edgeLabel("属于.ec").remove();
graph.schema().edgeLabel("拥有.ee").remove();
graph.schema().edgeLabel("有.ce").remove();
graph.schema().edgeLabel("有.cc").remove();
graph.schema().edgeLabel("有.ee").remove();
graph.schema().edgeLabel("用.ee").remove();
graph.schema().edgeLabel("开.ee").remove();
graph.schema().edgeLabel("属于.ec").remove();
graph.schema().edgeLabel("吃.ee").remove();
graph.schema().edgeLabel("听.ee").remove();
graph.schema().edgeLabel("是.ee").remove();
