遇到的問題一:
此問題是在安裝第二步,註冊主機時遇到的

解決方法:
一下是官方論壇中給出的方法,很好
Platforms:
- RHEL / CentOS 6.5
- Ambari 1.4 or later
Root Cause: The OpenSSL library available and installed by default on RHEL/CentOS 6.5 has a bug. Refer to https://bugzilla.redhat.com/show_bug.cgi?id=1025598 for detailed information on the bug.
Remedy:
- Check the OpenSSL library version installed on your host(s):
rpm -qa | grep openssl openssl-1.0.1e-15.el6.x86_64
- If the output says openssl-1.0.1e-15.x86_64 (1.0.1 build 15) you will need to upgrade the OpenSSL library by running the following command:
yum upgrade openssl
- Verify you have the newer version of OpenSSL (1.0.1 build 16):
rpm -qa | grep openssl
openssl-1.0.1e-16.el6.x86_64
- Restart Ambari Agent(s) and Click Retry Failed on the Wizard
問題二:
在安裝到倒數第二步“Install, Start and Test”時,一直安裝不成功,提示
[Errno 256] No more mirrors to try
解決方法:
輸入下面的命令即可解決問題:
- yum clean all
- yum makecache
