NEO4J安装指南Linux篇

1.JAVA环境——neo4j要求JDK8

查看Java版本

[root@tac software]# java -version

java version "1.8.0_121"

Java(TM) SE Runtime Environment (build 1.8.0_121-b13)

Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

You have new mail in /var/spool/mail/root

[root@tac software]#

2.创建一个用户neo4j,用来管理Neo4j 。当然这不是必须的。也可以是其它账号或root账号。

[root@tac neo4j-community-3.3.6]# groupadd nosql

[root@tac neo4j-community-3.3.6]# useradd -G nosql neo4j

3.解压

[root@tac ~]# tar -zxvf neo4j-community-3.3.6-unix.tar.gz -C /usr/local

4.修改环境变量

[root@tac neo4j-community-3.3.6]# vi /etc/profile

export NEO4J_HOME=/usr/local/neo4j/neo4j-community-3.3.6

export PATH=$PATH:$NEO4J_HOME/bin

保存退出后执行更改

[root@tac neo4j-community-3.3.6]# source /etc/profile

5.修改配置文件/etc/security/limits.conf

[root@tac neo4j-community-3.3.6]# vim /etc/security/limits.conf

neo4j soft nofile 40000

neo4j hard nofile 40000

6.验证

[root@tac neo4j-community-3.3.6]# neo4j version

neo4j 3.3.6

[root@tac neo4j-community-3.3.6]# neo4j

Usage: neo4j { console | start | stop | restart | status | version }

7.配置neo4j

创建数据库目录

[root@tac neo4j-community-3.3.6]# mkdir /usr/local/neo4j/data

修改配置文件

[root@tac neo4j-community-3.3.6]# vi neo4j-community-3.3.6/conf/neo4j.conf

指定数据库目录位置

dbms.active_database=/usr/local/neo4j/data/graph.db

dbms.directories.import=import

dbms.memory.heap.initial_size=512m

dbms.memory.heap.max_size=512m

指定运行的主机

dbms.connectors.default_listen_address=0.0.0.0

##或者本机IP

dbms.connectors.default_advertised_address=0.0.0.0

##或者本机IP

dbms.connector.bolt.enabled=true

dbms.connector.bolt.tls_level=OPTIONAL

dbms.connector.bolt.listen_address=:7687

dbms.connector.http.enabled=true

dbms.connector.http.listen_address=:7474

dbms.connector.https.enabled=true

dbms.connector.https.listen_address=:7473

dbms.tx_log.rotation.retention_policy=1 days

dbms.jvm.additional=-XX:+UseG1GC

dbms.jvm.additional=-XX:-OmitStackTraceInFastThrow

dbms.jvm.additional=-XX:+AlwaysPreTouch

dbms.jvm.additional=-XX:+UnlockExperimentalVMOptions

dbms.jvm.additional=-XX:+TrustFinalNonStaticFields

dbms.jvm.additional=-XX:+DisableExplicitGC

dbms.jvm.additional=-Djdk.tls.ephemeralDHKeySize=2048

dbms.jvm.additional=-Djdk.tls.rejectClientInitiatedRenegotiation=true

dbms.windows_service_name=neo4j

dbms.jvm.additional=-Dunsupported.dbms.udc.source=tarball

8.开放7474、7687、7473端口

使用iptables开放如下端口

[root@tac neo4j-community-3.3.6]# /sbin/iptables -I INPUT -p tcp --dport 7474 -j ACCEPT

[root@tac neo4j-community-3.3.6]# /sbin/iptables -I INPUT -p tcp --dport 7687 -j ACCEPT

[root@tac neo4j-community-3.3.6]# /sbin/iptables -I INPUT -p tcp --dport 7473 -j ACCEPT

保存

[root@tac neo4j-community-3.3.6]# /etc/rc.d/init.d/iptables save

重启服务

[root@tac neo4j-community-3.3.6]# service iptables restart

9.启动

[root@tac neo4j-community-3.3.6]# neo4j start
