Linux部署neo4j

本教程在Linux上部署neo4j

安装neo4j之前要先配置java环境。

[root@SCF-XJ00600]# java 一version #查看是否配置了java环境
openjdk version”1.8.0_161”
OpenJDK Runtime Environment (build 1.8.0 161一b14)
openJDK 64一Bit Server VM(build 25.161一b14, mixed mode)

[root@SCF-XJ00600 bin]# whereis java  #寻找java的安 装路径
java: usr/bin/java /usr/lib/java /etc/java usr/share/java /usr/share/man/man1/java.1.gz
[root@SCF-XJ00600 bin]# ls 一lrt /usr/bin/java
lrwxrwxrwx. 1 root root 22 Jul 19 16:36 /usr/bin/java -> /etc/alternatives/java
[root@SCF-XJ00600 bin]# 1s 一1rt /etc/alternatives/java  #打印出来的结果末尾就是java的路径，环境变量就按照这个配置
lrwxrwxrwx. 1 root root 71 Jul 19 16:36 /etc/alternatives/java -> /usr/lib/jvm/java一1.8.0一openjdk一1.8.0.161一2.b14.e17.x86_ 64/jre/bin/java

[root@SCF一XJ00600 jvm]# vim /etc/profile #添加java环境变量
export JAVA_HOME=/usr/lib/jvm/java一1.8.0一openjdk-1.8.0.161一2.b14.e17.x86 64/jre
export PATH= $JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/bin/dt.jar:$JAVA_H0ME/lib/tools.jar

[root@SCF-XJ00600 jvm]# source /etc/profile  #使环境变量生效
[root@SCF-XJ00600 jvm]# echo $JAVA_HOME   #打印java环境变量
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.161-2.b14.e17.x86_64/jre/bin/java

开始安装neo4j，首先要去官网下载neo4j的Linux版本，然后利用工具导入到Linux下面

```powershell
[root@SCF-XJ00600 software]# tar -zxvf neo4j-community-3.5.8-unix.tar.gz 一C /opt/moudles
#必须在与移动文件处于同一目录，方可解压指定目录下的安装包到指定目录下
neo4j-community-3.5.8/
neo4j-community-3.5.8/run/
neo4j-community-3.5.8/plugins/
neo4j-community-3.5.8/conf/

neo4i-community-3.5.8/lib/istack-commons-runtime-3.0.5.jar
neo4j-community-3.5.8/1ib/FastInfoset一1.2.13.jar
[root@SCF-XJ00600 opt]# cd moudles
[root@SCF-XJ00600 moudles]#1s
neo4j-community-3.5.8
[root@SCF-XJ00600 moudles]# cd neo4j-community-3.5.8

```powershell
[root@SCF-XJ00600 bin]# pwd
/opt/moudles/neo4j-community-3.5.8/bin #必须到这个目录下面才能开启neo4j服务
[root@SCF-XJ00600 bin]# ./neo4j start

[root@SCF-XJ00600 bin]# ./ neo4j status #查看neo4j状态
Neo4j is running at pid 140268
You have new mail in /var/spool/mail/root

[root@SCF-XJ00600 jvn]# vim /etc/profile #添加NEO4J环境变量
export NEO4J_HOME=/opt/moudles/neo4j-community-3.5.8
export PATH=$PATH:$NE04J_HONE/bin
[root@SCF-XJ00600 1ib]# source /etc/profile #环境变量生效

现在我们去浏览器输入：
http://0.0.0.0:7474/browser/ 即可访问

其中0.0.0.0要改为你的服务器的地址即可
