OrientDB分布式安装文档

发表于 | 分类于 | | 阅读次数 |

step 1:在虚拟机centos上新建用户jdorientdb,下载orientdb包解压到 /software/orientdb目录

step 2:设置ORIENTDB_HOME环境变量

vim ~/.bash_rc
export ORIENTDB_HOME="your soft directory"
source ~/.bash_rc

step 3:修改config/orientdb-server-config.xml，设置用户登录密码

1

<users>
    <user resources="*" password="jdorientdb" name="jdorientdb"/>
</users>

step 4:修改bin/orientdb.sh

orientdb启动默认需要root权限，修改配置去除root权限限制

# You have to SET the OrientDB installation directory here
ORIENTDB_DIR="$ORIENTDB_HOME"
ORIENTDB_USER="jdorientdb"
start方法中注释root权限执行：
#su $ORIENTDB_USER -c "cd \"$ORIENTDB_DIR/bin\"; 
/usr/bin/nohup ./server.sh 1>$LOG_DIR/orientdb.log 2>$LOG_DIR/orientdb.err &
stop方法中注释root权限执行：
#su $ORIENTDB_USER -c "cd \"$ORIENTDB_DIR/bin\";
/usr/bin/nohup ./shutdown.sh 1>>$LOG_DIR/orientdb.log 2>>$LOG_DIR/orientdb.err &

step 5:配置集群中各节点发现服务，修改configh/azecast.xml

<group>
    <name>jdorientdb</name>
    <password>jdorientdb</password>
</group>
<network>
    <port auto-increment="true">2434</port>
    <join>
        <multicast enabled="false">
            <multicast-group>235.1.1.1</multicast-group>
            <multicast-port>2434</multicast-port>
        </multicast>
         <tcp-ip enabled="true">#配置待优化
                <member>jdorientdb1:2434</member>
                <member>jdorientdb2:2434</member>
                <member>jdorientdb3:2434</member>
                <member>jdorientdb4:2434</member>
            </tcp-ip>           
    </join>
</network>

step6:修改config/default-distributed-db-config.json

{
  "autoDeploy": true,
  "readQuorum": 1,
  "writeQuorum": "majority",
  "executionMode": "asynchronous",
  "readYourWrites": true,
  "servers": {
    "jdorientdb1": "master",
    "jdorietndb2":"master",
    "jdorientdb3":"master",
    "jdorientdb4":"master"
  },
  "clusters": {
    "internal": {
    },
    "*": {
      "servers": ["jdorientdb1","jdorientdb2","jdorientdb3","jdorientdb4"]
    }
  }
}

step 7:每台虚拟机分别设置ip别名，修改/etc/hosts

10.14.133.18    jdorientdb2
10.14.133.13    jdorientdb1
10.14.133.25    jdorientdb3
10.14.133.75    jdorientdb4

step 8:将配置好的orientdb分别发送到其他虚拟机

1
scp -r /software/orientdb jdorientdb@jdorientdb2:/software/jdorientdb

step 9:分别启动每台虚拟机上的orientdb进程

1
2
3
nohup bin/dserver.sh > tmp.log &
首次启动需要设置nodeName，设置为与ip别名一致
