步骤一：启动为前台：bin/hiveserver2
步骤二：启动为后台：nohup bin/hiveserver2 1>/var/log/hiveserver.log 2>/var/log/hiveserver.err &
1：启动成功后，可以在别的节点上用beeline去连接
方式一：
hive/bin/beeline 回车，进入beeline的命令界面
输入命令连接hiveserver2
beeline> !connect jdbc:hive2//master:10000
（master机器是hiveserver2所启动的那台主机名，端口默认是10000）
方式二：
或者启动就连接：
bin/beeline -u jdbc:hive2://master:10000 -n hadoop
接下来就可以做正常sql查询了
1：将Hive作为一个服务器，其他机器可以作为客户端进行访问：
![]()
2：然后寻找符合thrift的这种协议的客户端来连这个服务，然而hive自带这种客户端（我这里复制本台机器，弄了两个窗口）：
![]()
然后呢，就是开启了命令行客户端了，然后了连接你的hive即可。我这里遇到一个错误，顺手贴一下吧。
造成这个错误的原因是!connect jdbc:hive2//master:10000写成!connect jdbc:hive2//localhost:10000即可。
1 [root@master apache-hive-1.2.1-bin]# cd bin/
2 [root@master bin]# ls
3 beeline ext hive hive-config.sh hiveserver2 metatool schematool
4 [root@master bin]# ./beeline
5 Beeline version 1.2.1 by Apache Hive
6 beeline> !connect jdbc:hive2//master:10000

12 No known driver to handle "jdbc:hive2//master:10000"
然后呢我写成beeline> !connect jdbc:hive2://localhost:10000回车。会让你输入账号和密码，这里直接输入你的登陆linux的账号和密码即可，我习惯使用root和其密码操作，虽然不好，但是这里直接输入root账号，123456密码即可登陆。
