環(huán)境要求

1、虛擬機（CentOS7.3）
2、關閉防火墻和SELinux
3、配置好JDK

Cassandra的安裝啟動

1、下載Cassandra安裝包（使用3.0以上的，為兼容hugegraph）

Downloading Cassandra 下載最新穩(wěn)定發(fā)行版
解壓：tar -zxvf apache-cassandra-3.11.3-bin.tar.gz -C /usr/local/

2、新建數(shù)據(jù)存儲路徑

mkdir /var/lib/cassandra/data
mkdir /var/lib/cassandra/commitlog
mkdir /var/lib/cassandra/saved_caches

3、配置${CASSANDRA_HOME}/conf/cassandra.yaml

（${CASSANDRA_HOME}為Cassandra安裝路徑）

基本配置

data_file_directories:
    - /var/lib/cassandra/data  // 數(shù)據(jù)文件存放路徑。打開這個注釋，注意不要合并成一行，合并成一行好像會出問題，這里要與前面新建的文件夾對應。
commitlog_directory: /var/lib/cassandra/commitlog // 操作日志文件存放路徑。打開注釋，與前面新建的文件夾對應。
saved_caches_directory: /var/lib/cassandra/saved_caches  // 緩存文件存放路徑。打開注釋，與前面新建的文件夾對應。

開啟默認密碼

authenticator: PasswordAuthenticator  // 默認AllowAllAuthenticator
authorizer: CassandraAuthorizer // 默認AllowAllAuthorizer

啟動后使用：./cqlsh -u cassandra -p cassandra ip port

CREATE USER myusername WITH PASSWORD 'mypassword' SUPERUSER;（這里用戶有兩種，一個是superuser，一種是nosuperuser）

供外部工具連接CassandraManager訪問

rpc_address: 0.0.0.0 // 用于監(jiān)聽客戶端連接的地址，默認127.0.0.1
broadcast_rpc_address: 1.2.3.4 // 若rpc_address設置0.0.0.0，則要放開此注釋

集群模式

cluster_name: 'xxx'  // 集群名稱。同一個集群要使用同一名稱
- seeds: "192.168.x.x"  // 集群種子節(jié)點ip,新加入集群的節(jié)點從種子節(jié)點中同步數(shù)據(jù)?？膳渲枚鄠€，中間用逗號隔開。
listen_address: 127.0.0.1  // 需要監(jiān)聽的IP或主機名。改成本機IP

4、啟動服務（啟動后默認端口為9042）

cd ${CASSANDRA_HOME}/bin
./cassandra -R   # root用戶啟動

部署 HugeGraph

1、先安裝 hugegraph-0.7.4

下載 hugegraph-0.7.4.tar.gz
解壓：tar -zxvf hugegraph-0.7.4.tar.gz -C /home/hugegraph

2、配置${hugegraph_home}/conf:rest-server.properties和hugegraph.properties

rest-server.properties

# bind url
restserver.url=http://127.0.0.1:8080    // 如果被占用，可改為其他端口，等會配置hugegraph-studio用到

# gremlin url to connect
gremlinserver.url=http://127.0.0.1:8182  // 基本不動

# graphs list with pair NAME:CONF_PATH
graphs=[hugegraph:conf/hugegraph.properties]

# authentication
#auth.require_authentication=
#auth.admin_token=
#auth.user_tokens=[]

hugegraph.properties（以Cassandra數(shù)據(jù)庫為例）

# rocksdb backend config
#backend=rocksdb

#rocksdb.data_path=/path/to/disk
#rocksdb.wal_path=/path/to/disk

# cassandra backend config
cassandra.host=localhost    // Cassandra安裝主機的IP
cassandra.port=9042           // hugegraph支持的端口目前限制在[1024-10000]
cassandra.username=
cassandra.password=
#cassandra.connect_timeout=5

# palo backend config
#palo.host=127.0.0.1

2、配置${hugegraph-studio_home}/conf/hugegraph-studio.properties

studio.server.port=8088  // 頁面訪問端口
studio.server.host=localhost   // 允許訪問地址，建議改為 0.0.0.0
