## 图数据库titan 和 rexster安装手册 ##

titan是图数据库, rexster是图显示服务 titan 安装 下载 titan 0.3.2 解压 titan-all-0.3.2.zip 到 /opt/hugedata/share/ 解压后得到 /opt/hugedata/share/titan-all-0.3.2/ 建立软连接 cd /opt/hugedata/share/ ln -s titan-all

titan是图数据库, rexster是图显示服务

### titan 安装 ###

下载 titan 0.3.2

解压 titan-all-0.3.2.zip 到 /opt/hugedata/share/  
解压后得到 /opt/hugedata/share/titan-all-0.3.2/  
建立软连接  
cd /opt/hugedata/share/  
ln -s titan-all-0.3.2 titan

/etc/profile 增加  
export TITAN\_HOME=/opt/hugedata/share/titan  
source /etc/profile  
\----------------------  
测试titan, 生成graph  
cd $TITAN\_HOME  
bin/gremlin.sh

gremlin> g = GraphOfTheGodsFactory.create('/tmp/titan')   
==>titangraph\[local:/tmp/titan\]  
gremlin> saturn = g.V('name','saturn').next()  
==>v\[4\]  
gremlin> saturn.map()  
==>name=saturn  
==>age=10000  
==>type=titan  
gremlin> saturn.in('father').in('father').name  
==>hercules

chmod 777 /tmp/titan

### rexster 安装 ###

下载 rexster 2.3.0  
  
解压 rexster-server-2.3.0.zip 到 /opt/hugedata/share/  
解压后得到 /opt/hugedata/share/rexster-server-2.3.0/  
建立软连接  
cd /opt/hugedata/share/  
ln -s rexster-server-2.3.0 rexster  
cd /opt/hugedata/share/rexster  
mkdir logs  
chmod 777 logs

打开 bin/rexster-service.sh  
修改变量 REXSTER\_DIR="/opt/hugedata/share/rexster-server-2.3.0"  
修改变量 REXSTER\_LOG\_DIR="/opt/hugedata/share/rexster-server-2.3.0/logs"

ln -s /opt/hugedata/share/rexster/bin/rexster-service.sh /etc/init.d/rexster  
chkconfig --add rexster

cd /opt/hugedata/share/rexster  
修改 rexster.xml  
修改配置 <rexster>/<http>/<server-host> 到安装机器 <host ip>

修改配置 <rexster>/<http>/<base-uri> 到安装机器 http://<host ip>

/etc/profile 增加  
export REXSTER\_HOME=/opt/hugedata/share/rexster

source /etc/profile

cd /opt/hugedata/share/rexster  
mkdir ext/titan  
cp $TITAN\_HOME/lib/\* $REXSTER\_HOME/ext/titan

bin/rexster-service.sh start  
检查 logs/service.err, logs/service.log

rexster测试页面, 测试例子图是否能显示

http://<rexster 服务启动机器ip>:8182

### rexster 使用  titan ／local 为backend ###

cd /opt/hugedata/share/rexster  
bin/rexster-service.sh stop

修改rexster.xml增加 <rexster>/<graphs>/<graph> 部分

<graph>  
<graph-name>titanexample</graph-name>  
<graph-type>com.thinkaurelius.titan.tinkerpop.rexster.TitanGraphConfiguration</graph-type>  
<graph-location>/tmp/titan</graph-location>  
<graph-read-only>false</graph-read-only>  
<properties>  
<storage.backend>local</storage.backend>  
<storage.buffer-size>100</storage.buffer-size>  
</properties>  
<extensions>  
<allows>  
<allow>tp:gremlin</allow>  
</allows>  
</extensions>  
</graph>

bin/rexster-service.sh start

rexster测试页面： http://<rexster host ip>:8182

### rexster 使用  titan ／hbase 为backend ###

cd /opt/hugedata/share/rexster  
bin/rexster-service.sh stop

导入数据到 hbase

修改 rexster.xml, 增加一下

<graph>  
<graph-enabled>true</graph-enabled>  
<graph-name>ipgraph</graph-name>  
<graph-type>com.thinkaurelius.titan.tinkerpop.rexster.TitanGraphConfiguration</graph-type>  
<graph-location></graph-location>  
<graph-read-only>false</graph-read-only>  
<properties>  
<storage.backend>hbase</storage.backend>  
<storage.hostname>hbase zookeeper quorum ip, 逗号分隔</storage.hostname>  
<storage.tablename>表名</storage.tablename>  
</properties>  
<extensions>  
<allows>  
<allow>tp:gremlin</allow>  
</allows>  
</extensions>  
</graph>

bin/rexster-service.sh start
