ERROR 2018-08-10 11:03:19,618 NetUtil.py:97 - SSLError: Failed to connect. Please check openssl library versions.
solution:
1. Check if OS openssl is the latest version, if not, please update.
[root@node-1 ~]# rpm -qa | grep openssl
openssl-1.0.1e-57.el6.x86_64
openssl-devel-1.0.1e-57.el6.x86_64
更新openssl
[root@node-1 ~]# yum update openssl
重启ambari-server
[root@node-1 ~]# ambari-server restart
2. If not possible, modify /etc/pyth/cert-verification. CFG configuration file
verify=disable
modify /etc/ambari-agent/conf/ambari-agent.ini and add the following
in [security]
force_https_protocol=PROTOCOL_TLSv1_2
restart ambari-agent
[root@node-1 ~]# ambari-agent restart
