简介 最近给孩子买了三国演义，可是三国人物关系太复杂，就想着把三国人物关系做成一张图，这样方便看，整好neo4j图数据库非常适合社交关系的处理，下面就一起来看看，如何使用neo4j生成三国人物社交关系图。
neo4j安装 现在docker很流行，也很方便，在这里，我就用docker快速搭建一个neo4j图数据库服务。
拉取neo4j镜像
[root@mysql ~]#docker pull neo4j
[root@mysql ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
neo4j latest ce22583052bf 6 days ago 546MB
创建neo4j的docker容器
[root@mysql ~]#docker run -id -d --publish=7474:7474 --publish=7687:7687 neo4j
[root@mysql ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
bc33fcdae7f4 neo4j "/sbin/tini -g -- /d鈥 4 hours ago Up 4 hours 0.0.0.0:7474->7474/tcp, 7473/tcp, 0.0.0.0:7687->7687/tcp hopeful_roentgen
到这里，图数据库的服务已经搭建好了，剩下的就是将数据导入。
准备三国人物数据 在这里，我已经准备好了三国演义中蜀国主要人物的关系表，将这些数据库拷贝到linux系统的a.txt文件

使用awk获取不重复的人物名称
cat a.txt |awk '{print $1"\n"$2}'|sort|uniq > b.sql
生成neo4j图数据节点插入语句
[root@mysql ~]# cat b.sql |awk '{print "create (country:shu { name:'\''"$1"'\''});"}'
create (country:shu { name:'法正'});
create (country:shu { name:'甘夫人'});
create (country:shu { name:'关平'});
create (country:shu { name:'关兴'});
create (country:shu { name:'关羽'});

生成neo4j图数据人物关系语句

** 执行插入语句** 将上面生成的节点和关系语句在neo4j中执行，就可以了。然后查询，就可以看到效果图了
