ambari2.6.50 openssl 版本问题：SSLError: Failed to connect. Please check openssl library versions. Openssl error upon host registration

I'm trying to register hostnames in Ambari but getting the error below. We tried to run yum update openssl but its got the latest version. 
We tried to run yum - update it didn’t help. I also tried removing the other openssl packages openssl-devel-1.0.1e-42.el6.x86_64, 
openssl098e-0.9.8e-17.el6.centos.2.x86_64 and restarting the ambari server/agents and same error. Tried running yum -y install opens* as well but didn’t help. Any ideas?

Yes. That is a known issue. Modify Ambari Server's java.home to the standard oracle jdk.

that fixed it. Thanks.

Hi,

We are also facing same issue. Even after setting java.home=/usr/jdk64/jdk1.8.0_40 in ambari.properties , it is not resolved.

Is standard oracle jdk path different from this ?

Below are logs snippet from ambari-agent.log ::

ERROR 2015-12-24 18:43:31,604 NetUtil.py:77 - [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590) ERROR 2015-12-24 18:43:31,604 NetUtil.py:78 - SSLError: Failed to connect.

@gaurav sharma I am actually facing the same issue, I have the same SSL error message during the registration. Did you find a solution ?

gaurav sharma· 2015年12月26日 05:51 1

@Ali Gouta No, we are still trying to figure out the solution.

OpenSSl version in my case is ::

[root@dehdteste7778b54apse01 ~]# rpm -qa | grep openssl

openssl-devel-1.0.1k-13.88.amzn1.x86_64

openssl-1.0.1k-13.88.amzn1.x86_64

Can this be a problem ?

Ali Gouta· 2015年12月26日 23:11 0

@gaurav sharma

In the documentation, it is said that we should user OpenSSL (v1.01, build 16 or later). So I think you should upgrade your OpenSSL version. Actually, I am running openssl-1.0.1e-42.el6_7.1.x86_64, and still not being able to register my agent :(

[ RESOLVED ]

Gone through same issue only when we are using oVirt Virtualization For our cluster deployment.

Only following solution resolved the problem (Thanks to @bing lv and @Deven Fan:

By adding below config in [security] section of

1. vi /etc/ambari-agent/conf/ambari-agent.ini
2. force_https_protocol=PROTOCOL_TLSv1_2

1. vi /etc/python/cert-verification.cfg
2. [https]
3. verify=disable

Perfect solution, it works

I've been stuck with this problem for a day and I've tried everything on this post, but nothing works.

However, the link from this post solved my problem so I thought I should link it to here.

https://community.hortonworks.com/questions/121978/openssl-compatibility.html?childToView=138080#answer-138080

Basically, disable certificate verification on all nodes

1. vi /etc/python/cert-verification.cfg
2. [https]
3. verify=disable

good luck.

Hello

I've just add these two line below under security section and it works 
[security]
ssl_verify_cert=0
force_https_protocol=PROTOCOL_TLSv1_2

In our case the problem was that the other nodes have OpenJDK instead of oracle's, installing Oracle JDK on those nodes solves the problem

i have faced the same issue, for this Java up-grade is not required.

Just intall the openssl package and run installation host registration went fine.

1) from vm connect to the internet

2) Install the opnssl package

#yum install openssl

if it installed fine, you can proceed with host Registration .

it worked for me.

I use openjdk 1.8,then the problem is resolved.

So, I think is just the java version problem...

I am still not very clearly what's the resolve?

rpm -qa | grep java

tzdata-java-2014g-1.el6.noarch

java-1.6.0-openjdk-1.6.0.0-11.1.13.4.el6.x86_64

java-1.7.0-openjdk-1.7.0.95-2.6.4.0.el6_7.x86_64

alternatives --display java

java - status is auto. Current `best' version is /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java.

and the python problem @Ali Gouta said ,it still the same ....
