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 7 scan complete in 1ms 8 17/12/12 04:42:53 [main]: ERROR beeline.ClassNameCompleter: Fail to parse the class name from the Jar file due to the exception:java.io.FileNotFoundException: minlog-1.2.jar (No such file or directory) 9 17/12/12 04:42:53 [main]: ERROR beeline.ClassNameCompleter: Fail to parse the class name from the Jar file due to the exception:java.io.FileNotFoundException: objenesis-1.2.jar (No such file or directory) 10 17/12/12 04:42:53 [main]: ERROR beeline.ClassNameCompleter: Fail to parse the class name from the Jar file due to the exception:java.io.FileNotFoundException: reflectasm-1.07-shaded.jar (No such file or directory) 11 scan complete in 5708ms 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。

登陆以后即可以进行操作，演示如下所示：
停更......
