Ambari部署HDP出现的问题总结

此问题是在安装第二步，注册主机时遇到的

error:100AE081:elliptic curve routines:EC_GROUP_new_by_curve_name:unknown group

ERROR 2015-02-06 20:10:20,023 NetUtil.py:58 - SSLError: Failed to connect. Please check openssl library versions.

Connection to Slave5.domain.dev closed.

SSH command execution finished

host=Slave5.domain.dev, exitcode=0

Command end time 2015-02-06 12:07:47

 

解决办法：

rpm -qa | grep openssl

yum upgrade openssl

rpm -qa | grep openssl

 

在安装到倒数第二步“Install, Start and Test”时，一直安装不成功，提示[Errno 256] No more mirrors to try

解决办法：

yum clean all

yum makecache

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe6 in position 2: ordinal not in range(128)  

Python中使用中文字符串报错，解决方案： 

在出现问题的页加上如下三行即可：
import sys
reload(sys)
sys.setdefaultencoding('utf-8')

 

问题： [root@cddserver2 ~]# yum -y install gcc-* Loaded plugins: fastestmirror, presto Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was 14: PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org'" Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again

 原因：  dns服务器没有配置正确  

 解决办法：
 1、打开文件/etc/resolv.conf在其中添加：  nameserver 8.8.8.8    
 2、然后重启网卡：使用命令: service network restart
