1：集群规划
nosql1 192.168.100.131
nosql2 192.168.100.132
nosql3 192.168.100.133
2：在ubutu客户端下载解压neo4j安装包，并上传到集群服务器
mmicky@wyy :/app$ sudo tar zxf /home/mmicky/Soft/nosql/neo4j-enterprise-1.9.4-unix.tar.gz
mmicky@wyy :/app$ sudo chown -R root:root neo4j-enterprise-1.9.4
mmicky@wyy :/app$ sudo mv neo4j-enterprise-1.9.4 neo4j194
mmicky@wyy :/app$ sudo scp -r neo4j194 [email protected]:/app/
mmicky@wyy:/app$ sudo scp -r neo4j194 [email protected]:/app/
mmicky@wyy:/app$ sudo scp -r neo4j194 [email protected]:/app/
3：打开节点终端，编辑相关的配置文件
注意：Neo4j对打开文件数至少是40000，所以要对系统参数进行设置，不然启动的时候会出现如下的错误：
节点nosql1(192.168.100.131)
[root@nosql1 neo4j194]# vi /etc/security/limits.conf

节点nosql2(192.168.100.132)
[root@nosql2 neo4j194]# vi /etc/security/limits.conf

4：由于修改了系统配置文件，重启各节点后再启动集群
[root@nosql1 neo4j194]# bin/neo4j start
[root@nosql2 neo4j194]# bin/neo4j start
[root@nosql3 neo4j194]# bin/neo4j start
5：访问集群
在客户机ubuntu上打开浏览器，录入下列几个地址都可访问：
http://192.168.100.131:7474/webadmin
http://192.168.100.132:7474/webadmin
http://192.168.100.133:7474/webadmin
