在macos上部署单机版es，遇到一些问题，做个记录
1、es服务启动报错：received plaintext http traffic on an https channel, closing connection
错误信息
错误原因：ES8默认开启了 ssl 认证。
解决方案：elasticsearch.yml配置文件
将xpack.security.enabled设置为false
xpack.security.enabled: false
2、二次启动报错：org.elasticsearch.ElasticsearchException: not all primary shards of [.geoip_databases] index are active
错误信息
错误原因：es启动时会去更新地图的一些数据库，这里直接禁掉即可
ingest.geoip.downloader.enabled: false
解决方案：配置文件conf/elasticsearch.yml，增加配置
ingest.geoip.downloader.enabled: false
访问http://localhost:9200/出现以下信息，数名es服务启动成功
