Hive部署远程模式这样的进程单独开启，使用客户端工具或者命令行进行远程连接这样的服务，即远程模式。客户端可以在任何机器上，只要连接到这个server，就可以进行操作。客户端可以不需要密码。将qianfeng01的节点作为服务器节点，将qianfeng02作为客户端节点，将qianfeng01节点中配置好hive远程发送给qianfeng02节点。想要连接metastore服务的客户端必须配置如下属性和属性值。远程模式是一个服务器在在一台节点，客户端在其他节点上。千锋大数据Hadoop全新增强版-先导片。阅读详情

在启动hive前，一定在保证集群的mysql和Hadoop是启动成功的，

Hadoop是存储实质数据==
mysql是存储hive的元数据（映射关系数据）

Hadoop的启动命令：start-all.sh Hadoop
进程名：NameNode、DataNode
hadoop的关闭命令：stop-all.sh

[root@node01 ~]# start-all.sh 
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [node01]

在hadoop启动集群成功后，HDFS会进入安全模式，等安全模式结束后再开始启动hive

注意hdfs在安全模式下：对数据只有查看的权限，

没有删除，上传，创建的权限

Mysql的启动命令：mysql -u mysql_name(你的mysql的用户名） -p
按下回车执行后在输入你mysql的password

在这里插入图片描述

登录hadoop的web端查看是否退出安全模式，
Hadoop的web端口号为：50070**

在这里插入图片描述

此次启动的是hive远程模式，
第一代客户端：后台挂起启动
nohup /export/servers/hive/bin/hive --service metastore &
nohup /export/servers/hive/bin/hive --service hiveserver2 &

客户端在那就执行这个启动代码：/export/servers/hive/bin/beeline

！ connect jdbc:hive2://node01:10000
…username…:mysql_name
…password…: 可以不用输入，直接按回车即可

[root@node02 ~]# /export/servers/hive/bin/beeline
