4.导入Mysql表[size=9.0000pt]
[size=10.5000pt]执行以下语句导入数据库
[size=10.5000pt]# mysql -h localhost -uambari -p -Dambari < /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql
[size=10.5000pt]
[size=10.5000pt]
[size=10.5000pt]
[size=10.5000pt]# ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
5.启动Ambari-server
[size=10.5000pt][root@hdp1 ~]# ambari-server start
[size=10.5000pt]
[size=10.5000pt]
6.错误处理
[size=10.5000pt]　　如果出现错误，请注意查看日志，根据具体的错误内容进行处理，默认ambari-server的日志在/var/log/ambari-server/ambari-server.log里面。如果在处理日志的过程中或者后面安装的过程中出现一些莫名的错误，可以重置的安装。如果上面进行的默认数据库的配置，可以使用下面的代码重置ambari-server
[size=10.5000pt][root@hdp1 ~]# ambari-server stop [root@hdp1 ~]# ambari-server reset [root@hdp1 ~]# ambari-server setup
[size=10.5000pt]　　如果选择的是第二种方式，就需要先执行上面的语句，然后手动将mysql里面创建的数据库进行删除。然后再重新执行第二步的操作
file:///C:\Users\hg\AppData\Local\Temp\ksohtml\wps7453.tmp.png[size=12.0000pt]
[size=10.5000pt][root@hdp1 ~]# mysql -uroot -p[size=9.0000pt] [size=9.0000pt]mysql> drop database ambari; mysql> drop database hive; mysql> drop database oozie;
[size=10.5000pt]
[size=10.5000pt]　　如果在安装的过程中出现了错误，又想重新安装，可以在ambari-server开启的情况下，在所有节点执行下面的语句来移除已安装的包，然后再通过不同的情况选择上面两种方式的一种对ambari-server进行重置
[size=10.5000pt]# python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py --silent
[size=10.5000pt] 删除数据库
[size=10.5000pt]mysql -h localhost -uambari -p -Dambari <[size=10.5000pt] [size=10.5000pt]/var/lib/ambari-server/resources/Ambari-DDL-MySQL-DROP.sql
[size=10.5000pt]
五、安装配置部署HDP集群
1、登录
[size=10.5000pt]登录地址：主机ip+端口8080
[size=10.5000pt]登录界面，默认管理员账户登录，账户：admin 密码：admin

2、安装向导

（1）配置集群的名字为hadoop

（2）选择版本并修改为本地源地址
[size=12.0000pt]Repository填写：http://192.168.10.131/hdp

（3）安装配置
[size=10.5000pt]选择要安装的服务器和上传上面教程所拷贝出来的秘钥文件id_rsa

（4）安装ambari的agent，同时检查系统问题

[size=12.0000pt]可以点击“Click here to see the check results.[size=12.0000pt]” 查看存在的问题，并解决

如果报错：
[size=10.5000pt]ERROR 2018-05-30 00:12:25,280 NetUtil.py:96 - EOF occurred in violation of protocol (_ssl.c:579)
[size=10.5000pt]ERROR 2018-05-30 00:12:25,280 NetUtil.py:97 - SSLError: Failed to connect. Please check openssl library versions.
[size=10.5000pt]解决方式：
[size=10.5000pt]1.
[size=10.5000pt]修改/etc/python/cert-verification.cfg配置文件：
[size=10.5000pt]# vi /etc/python/cert-verification.cfg
[size=10.5000pt][https]
[size=10.5000pt]verify=disable
[size=10.5000pt]# vi /etc/ambari-agent/conf/ambari-agent.ini
[size=10.5000pt][security]
[size=10.5000pt]ssl_verify_cert=0
[size=10.5000pt]force_https_protocol=PROTOCOL_TLSv1_2
[size=10.5000pt]若还是不能注册ambari-agent,使用下面介绍的方式。
[size=10.5000pt]2.如果上面方式还不能注册，说明jdk版本不通过，使用默认oracle啊jdk，博主是（centos7.3，所以选择jdk1.8）
[size=10.5000pt]（1）先停掉：ambari-server stop；然后停止所有节点agent:ambari-agent stop
[size=10.5000pt]（2）卸载掉所有节点agent:rpm -qa | grep ambari-agent 得到对应版本，使用rpm -e ambari-agent-XXX卸载；
[size=10.5000pt]（3）启动setup：ambari-server setup，配置你的东西，直到选择jdk如下图：

[size=10.5000pt]
[size=10.5000pt]选择1，等下载安装完成，继续后续步骤。直到结束
[size=12.0000pt]（4）启动ambari：ambari-server start
[size=10.5000pt]
[size=10.5000pt]
[size=10.5000pt]如果这里出了问题，请检查上面所有的步骤有没有遗漏和未设置的参数。同时在重新修改了配置以后，最好是重置ambari-server来重新进行安装
[size=9.0000pt][root@master ~][size=9.0000pt]# # ambari-server stop [size=9.0000pt][root@master ~][size=9.0000pt]# # ambari-server reset #重置命令[size=9.0000pt] [root@master ~][size=9.0000pt]# # ambari-server setup #重新设置[size=9.0000pt] [root@master ~][size=9.0000pt]# # ambari-server start
[size=10.5000pt]
（5）选择要安装的服务

（6）选择分配服务

（7）选择
[size=10.5000pt]建议regionserver、client全都勾选上，第一个datanode根据主机的磁盘容量选择，nodemanager建议和datanode相同。

（8）定制化配置
[size=12.0000pt]Metrics设置密码
[size=12.0000pt]

[size=10.5000pt]

[size=12.0000pt]SmartSense设置密码

[size=10.5000pt]
[size=10.5000pt]
[size=10.5000pt]
（9） 显示配置信息

[size=10.0000pt]
（10）开始安装
[size=10.0000pt]安装各个服务，并且完成安装后会启动相关服务，安装过程比较长，如果中途出现错误，请根据具体提示或者[size=10.0000pt]log[size=10.0000pt]进行操作。[size=10.0000pt]

[size=10.5000pt]
[size=10.0000pt]
[size=10.0000pt]安装过程可以随时查看每个节点的安装进度及日志[size=10.0000pt]

[size=10.0000pt]
[size=12.0000pt]如果安装过程中出现报错缺少某个包或命令，可以配置一个yum源，如阿里、网易的
[size=10.5000pt]
[size=10.0000pt]全部安装成功界面如下[size=10.0000pt]

[size=10.0000pt]
[size=10.0000pt]
（11）安装完成

[size=10.0000pt]

[size=10.0000pt]
六、Hadooop开启高可用
