elasticsearch编译安装，不包含插件

复制安装ElasticSearch
	sudo docker pull elasticsearch:7.8.0
	sudo docker run -tid --name es7 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.8.0
		9300是集群节点指点的tcp通讯端口
		9200是http协议的web客户端RESTful端口
		discovery.type=single-node 表示，如果你正在使用单个节点开发，那就要添加这句话避开引导检查
	sudo docker start es7	
	sudo docker exec -ti es7 /bin/bash		
	sudo docker logs es7 	# 查看某个容器的日志
	
	现在就可以在浏览器输入 ip + 端口号 访问了。 如：http://localhost:9200/
	

如果sudo docker logs es7 发现内存不足
	sudo find / -name jvm.options
	sudo vi /var/lib/docker/overlay2/b926d7a38a6447554e36cab5da25d89b534f5ab3b95ed64954e19459abb49733/diff/usr/share/elasticsearch/config/jvm.options
	
	-Xms1g
	-Xmx1g
	
	#-Xms700m
	#-Xmx700m

	
	sudo find / -name elasticsearch.yml	
	sudo vi /var/lib/docker/overlay2/198a62213a46b756e1a57cf011a75b5cc0192f731ec1b573d275f57eddb4efeb/diff/usr/share/elasticsearch/config/elasticsearch.yml
	
	#减少内存暴增
		index.store.type: niofs
	
	#密码设置
		http.cors.enabled: true
		http.cors.allow-origin: "*"
		http.cors.allow-headers: Authorization
		xpack.security.enabled: true
		xpack.security.transport.ssl.enabled: true
	保存后
		重启后,重新进入容器,输入elasticsearch-setup-passwords interactive,按y确认后即可设置密码.
			以我的试验会得到以下报错，大致意思是抱怨连接不上这个URL			
				Connection failure to: http://localhost:9200/_security/_authenticate?pretty failed: Connection refused
				ERROR: Failed to connect to elasticsearch at http://localhost:9200/_security/_authenticate?pretty. Is the URL correct and elasticsearch running?

		重新来就可以了:
			elasticsearch-setup-passwords interactive -u 'http://localhost:9200'
		
		密码都设置为:
		123456
		
		Enter password for [elastic]:
		Reenter password for [elastic]:
		Enter password for [apm_system]:
		Reenter password for [apm_system]:
		Enter password for [kibana_system]:
		Reenter password for [kibana_system]:
		Enter password for [logstash_system]:
		Reenter password for [logstash_system]:
		Enter password for [beats_system]:
		Reenter password for [beats_system]:
		Enter password for [remote_monitoring_user]:
		Reenter password for [remote_monitoring_user]:
		Passwords do not match.
		Try again.
		Enter password for [remote_monitoring_user]:
		Reenter password for [remote_monitoring_user]:
		Changed password for user [apm_system]
		Changed password for user [kibana_system]
		Changed password for user [kibana]
		Changed password for user [logstash_system]
		Changed password for user [beats_system]
		Changed password for user [remote_monitoring_user]
		Changed password for user [elastic]
