關于Ambari的安全、訪問控制在這里有非常詳細的介紹。

Ambari用來管理大數據集群非常的方便，但是默認只支持HTTP協議，需要手動安裝、配置才能支持HTTPS協議。
步驟如下：
1、登陸到Ambari Server所在主機，依次執行如下命令

1） openssl genrsa -out $wserver.key 2048 2） openssl req -new -key $wserver.key -out $wserver.csr 3） openssl x509 -req -days 365 -in $wserver.csr -signkey $wserver.key -out $wserver.crt注：$wserver 就是Ambari Server 的host nameThe certificate you use must be PEM-encoded, not DER-encoded. If you attempt to use a DER-encoded certificate, you see the following error:unable to load certificate 140109766494024:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c :698:Expecting: TRUSTED CERTIFICATEYou can convert a DER-encoded certificate to a PEM-encoded certificate using the following command:openssl x509 -in cert.crt -inform der -outform pem -out cert.pemwhere cert.crt is the DER-encoded certificate and cert.pem is the resulting PEM-encoded certificate.2、執行 ambari-server setup-security命令Select 1 for Enable HTTPS for Ambari server.Respond y to Do you want to configure HTTPS ?Select the port you want to use for SSL. The default port number is 8443.Provide the complete path to your certificate file ($wserver.crt from above) and private key file ($wserver.key from above).Provide the password for the private key.Start or restart the Serverambari-server restart
