I succesfully installed Cloudera CDP Data Center on my CentOS7 virtual machine and after installing PostgreSQL i was unable to start the Cloudera Manager Server.   I ran the follwing command: "sudo service cloudera-scm-server start" When i tried to access the Cloudra Manager on localhost:7180 and received: "Firefox can’t establish a connection to the server at localhost:7180".   I checked the server status with the command: "service cloudera-scm-server status -l".
