RedisGraph 在Ubuntu18上安装和配置
参考：
https://redis.io/modules
https://github.com/RedisGraph

https://s3.amazonaws.com/artifacts.opencypher.org/openCypher9.pdf
编译RedisGraph
RG编译之后是一个模块：redisgraph.so
ubuntu 上:
# apt-get install build-essential cmake m4 automake peg libtool autoconf
# git clone https://github.com/RedisGraph/RedisGraph.git
# cd RedisGraph/ && makeRedis 配置
原来的配置：
# redis configuration
# http://www.cnblogs.com/wenanry/archive/2012/02/26/2368398.html
#
bind 127.0.0.1
port 7001
daemonize yes
cluster-enabled yes
cluster-node-timeout 12000
cluster-config-file /opt/redis-cluster/dev/cluster-node-7001.conf
pidfile /opt/redis-cluster/dev/run/redis-7001.pid
dir /opt/redis-cluster/dev/7001
logfile /opt/redis-cluster/dev/log/redis-7001.log
maxmemory 1g
maxmemory-policy noeviction
requirepass test
masterauth test
########################## SNAPSHOT DUMP MODE #########################
save 900 1
save 300 10
save 60 10000
dbfilename snapshotdump-7001.rdb
rdbcompression yes
########################## APPEND ONLY MODE ###########################
appendonly yes
appendfilename appendonly-7001.aof
appendfsync everysec
no-appendfsync-on-rewrite yes
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb更改之后的配置：
# redis configuration

# redisgraph not supports AOF
appendonly no注意：redisgraph 不支持AOF。以上配置在每个redis-server的节点都要。
测试 GRAPH.QUERY
启动 redis-cluster，然后登录：
＃ redis-cli -c -h 127.0.0.1 -p 7001 -a test测试：
0.0.1:7001> graph.query social "CREATE (:person {name: 'roi', age: 33, gender: 'male', status: 'married'})"
-> Redirected to slot [9628] located at 127.0.0.1:7002
1) 1) "Nodes created: 1"
2) "Properties set: 4"
3) "Query internal execution time: 0.768064 milliseconds"
127.0.0.1:7002>成功！关于 Cypher 语言，目前 RG 不支持 (a)-[ ]-(b) 。只能写成：(a)-[ ]->(b)。
