[#2]

You are using RHEL 7, what is your Python version? We do not support 2.7.9

[#3]

yes ,i'm using centos7,and the python version is 2.6.

[#4]

V can you confirm you setup passwordless ssh to each box? Alternatively, register agents manually http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.1.1/bk_ambari_reference_guide/content/ch_amb_ref...

Also review all pre-checks in our Ambari user guide

[#5]

I realy confirm all pre-checks.I don't know the problem like this

Do you know what's the reason maybe?

[#6]

I just saw a message it say cannot decide ascii character, can you make sure your FQDN is typed correctly and there are no extra characters present, both in Ambari agent properties, hosts file and web UI

[#7]

Can you check that hostname fqdn and ip address matching is correct?

[#8]

Yes,that's correct.

[#9 · Accepted solution]

Hey,thank both of you.i got it.The character in China is UTF8,and Ambari is ascii.And Python 2.6 for UTF8 has a bug.

[#10]

excellent, please accept the best answer.
