ELASTIC-PHP + IK分词器 + THINKPHP6 初次使用 （关键词查询）
环境：centos 6 php73 mysql56 ELASTIC7.71
1.安装elastic 使用华为云镜像更快哦 https://mirrors.huaweicloud.com/elasticsearch/
wget https://mirrors.huaweicloud.com/elasticsearch/7.7.1/elasticsearch-7.7.1-linux-x86_64.tar.gz
tar -zxvf elasticsearch-7.7.1-linux-x86_64.tar.gz 2.添加用户（用户启动elastic 不能用root所以） 去目录里面编辑配置 elastic.yml
groupadd elastic
useradd -g elastic elastic
chown -R elastic.elastic /etc/elasticsearch-7.7.1
vim config/elasticsearch.yml 配置如下 注意冒号后有空格
------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: hxx-node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/elastic/data
#
# Path to log files:
#
path.logs: /var/elastic/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 127.0.0.1
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, consult the network module documentation.

#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["hxx-node-1"]
cluster.routing.allocation.disk.watermark.flood_stage: 99%
cluster.routing.allocation.disk.threshold_enabled: false3.安装ik分词库（用于中文） 下载对应的哦 7.7.1
https://github.com/medcl/elasticsearch-analysis-ik/releases
不管你用何种方法 放到安装路径里 /etc/elasticsearch-7.7.1/plugins/ik
好了 切换到 elastic 然后运行elastic
su elastic
./bin/elastic -d可进行测试

1.composer 引入 elastic-php(使用phpstorm更方便)
"elasticsearch/elasticsearch": "~7.0",2.编辑elastic控制器类（包括 创建 增删改查 批量给导入）Ela.php
