redis GEO 使用和搭建 Redis 集群

<?php

use Illuminate\Support\Facades\Redis;

//redis GEO 使用
$redis = Redis::connection();
//添加或修改地理位置
$redis->command("geoadd", ['city', '120.20000', '30.26667', 'hangzhou', '116.41667', '39.91667', 'beijing', '121.47', '31.23', 'shanghai']);
//获取地理位置信息
$redis->command("geopos", ['city', 'hangzhou', 'beijing']);
//计算距离 单位可以是 m、km、ml、ft，分别代表米、千米、英里和尺
$redis->command("geodist", ['city', 'hangzhou', 'beijing','km']);
//获取指定元素范围的地理信息位置集合 例如查找距离杭州300km以内的城市的10个城市按距离排序
$redis->command("GEORADIUSBYMEMBER", ['city', 'hangzhou', '300', 'km', ['WITHCOORD', 'WITHDIST', 'WITHHASH', 'ASC', 'COUNT', 10]]);
//WITHDIST ： 在返回位置元素的同时， 将位置元素与中心之间的距离也一并返回。 距离的单位和用户给定的范围单位保持一致。
//WITHCOORD ： 将位置元素的经度和维度也一并返回。
//WITHHASH ： 以 52 位有符号整数的形式， 返回位置元素经过原始 geohash 编码的有序集合分值。
//ASC ： 根据中心的位置， 按照从近到远的方式返回位置元素。DESC ： 根据中心的位置， 按照从远到近的方式返回位置元素。
//根据 经纬度位置 获取最近300km以内的城市的10个城市按距离排序
$redis->command("GEORADIUS", ['city','120.20000', '30.26667', '300', 'km', ['WITHCOORD', 'WITHDIST', 'WITHHASH', 'ASC', 'COUNT', 10]]);
//删除位置信息
$redis->command("ZREM", ['city','hangzhou']);

docker exec -it rds1 /bin/sh
我们进去让每个节点建立连接
## 这里的IP对应你容器的IP  docker inspect mysqls_db1_1 查看容器ip
redis-cli -p 16371 --cluster create \
172.19.0.8:16371 \
172.19.0.9:16372 \
172.19.0.4:16373 \
172.19.0.5:16374 \
172.19.0.6:16375 \
172.19.0.7:16376 \
--cluster-replicas 1  # 这个为容器ip 集群无法通过外网访问

## 我们回车之后, 会告诉你节点分布 redis集群默认是1主1备所以节点都是成双的 不会出现单数
