OrientDB Install (安裝 OrientDB 2.2.36 版本)

Install Java

sudo yum install java -y

System prepare

讓 cluster 可以找到對方 (orientdb-server-config.xml內的 nodeName 要相同)

sudo vim /etc/hosts
...
192.168.21.46	orientdb-node-1
192.168.21.47	orientdb-node-2
...

設定服務運行帳號 orientdb@orientdb

sudo adduser orientdb -d /opt/orientdb
sudo passwd orientdb
sudo usermod -s /bin/bash orientdb

Install OrientDB

Get tar & untar

wget https://s3.us-east-2.amazonaws.com/orientdb3/releases/2.2.36/orientdb-community-importers-2.2.36.tar.gz
tar -zxvf orientdb-community-importers-2.2.36.tar.gz
sudo mv orientdb-community-importers-2.2.36 /opt/orientdb

/opt/orientdb/bin/dserver.sh

sudo vim /opt/orientdb/bin/dserver.sh
ORIENTDB_OPTS_MEMORY="-Xms2G -Xmx2G"

Change owner

sudo chown -R orientdb:orientdb /opt/orientdb

Set server management account root@root

su - orientdb
/opt/orientdb/bin/dserver.sh
exit

HA/Cluster (Distributed Configuration)

/opt/orientdb/config/orientdb-server-config.xml

sudo chmod 640 /opt/orientdb/config/orientdb-server-config.xml
sudo vim /opt/orientdb/config/orientdb-server-config.xml

/opt/orientdb/config/default-distributed-db-config.json

sudo vim /opt/orientdb/config/default-distributed-db-config.json
{
  "replication": true,
  "hotAlignment" : true,
  "autoDeploy": true,
  "readQuorum": 1,
  "writeQuorum": "majority",

  "clusters": {
    "internal": {
    },
    "*": {
      "servers": ["<NEW_NODE>"]
    }
  }
}

Run OrientDB as a Service (daemon)

/opt/orientdb/bin/orientdb.sh

sudo vim /opt/orientdb/bin/orientdb.sh
ORIENTDB_DIR="/opt/orientdb"
ORIENTDB_USER="orientdb"

sudo cp /opt/orientdb/bin/orientdb.service /etc/systemd/system
sudo vim /etc/systemd/system/orientdb.service
User=orientdb
Group=orientdb
ExecStart=/opt/orientdb/bin/dserver.sh

sudo systemctl daemon-reload
sudo systemctl start orientdb.service
sudo systemctl enable orientdb.service

確認 cluster 建立成功

sudo cat /opt/orientdb/log/orient-server.log.0 | grep "|"

note

一旦使用 /opt/orientdb/bin/dserver.sh 測試過，就要執行以下指令，再起service，因為會有檔案權限被變更為root:root。

sudo chown -R orientdb:orientdb /opt/orientdb

讓 cluster backup 可運行

sudo chown -R orientdb:orientdb /tmp/orientdb
