在ubuntu 16.04上面配置Neo4j生产环境

生产环境

系统：ubuntu 16.04 LTS
安装版本:Neo4j 3.1.3

安装

编写sh脚本

#!/bin/bash
# This script installs default Java Machine and latest version of enterprise Neo4j on your machine
# This script is compatible with Debian(8+) and Ubuntu (14.04+) as on Dec-21-2016

# update your distro
sudo apt-get update

# install the default JRE (required for running Neo4j)
sudo apt-get install default-jre -y

# the following commands add the neo4j repo to apt-get
wget -O - https://debian.neo4j.org/neotechnology.gpg.key | sudo apt-key add -
echo 'deb https://debian.neo4j.org/repo stable/' | sudo tee /etc/apt/sources.list.d/neo4j.list

# get packages from the Neo4j list. I know it's been run before, but I like to
# do this twice just to ensure nothing got left out earlier
sudo apt-get update

# Gets Neo4j enterprise. To get latest version use sudo apt-get install neo4j-enterprise
# sudo apt-get install neo4j-enterprise=x.x.x, e.g. sudo apt-get install neo4j-enterprise=3.1.0
sudo apt-get install neo4j-enterprise=3.1.3 -y

# Install vim
sudo apt-get install vim -y

echo "in case of 3.1.3, the conf file can be edited by running vim /etc/neo4j/neo4j.conf"

保存为install.sh之后给予运行权限就好了

而后使用命令neo4j console就可以开启neo4j了，通过访问http://localhost:7474/可以查看那个超级厉害的控制台（若提示权限不足，请用sudo）

默认配置信息

可通过vim /etc/neo4j/neo4j.conf查看
默认的文件目录如下

# Paths of directories in the installation.
dbms.directories.data=/var/lib/neo4j/data           #数据库目录
dbms.directories.plugins=/var/lib/neo4j/plugins     #插件目录
dbms.directories.certificates=/var/lib/neo4j/certificates   
dbms.directories.logs=/var/log/neo4j                #日志目录
dbms.directories.lib=/usr/share/neo4j/lib           #jar包目录
dbms.directories.run=/var/run/neo4j                 
dbms.directories.metric=/var/lib/neo4j/metrics

修改数据库目录

因为在后面的操作过程中几乎一定会遇到需要增加、修改数据文件和日志文件的情况，为了避免各种访问权限问题的打扰，我们可以将数据库的目录更改到另一个地方，首先先将默认数据库目录整个复制到新的目录下面，然后修改配置文件

dbms.directories.data=/home/ericwyn/neo4j/data      #更改后数据库目录地址

保存后使用命令neo4j restart重新启动一下neo4j就好了
