No package mssql-tools available

i want to install mssql-server in the centos 7 server ... i did the procedure before on other server before how ever for this one i could not able to install mssql-tools .. the mssql server is installed and works fine. what i am doing is i config the repo sudo curl -o /etc/yum.repos.d/msprod.repo https://packages.microsoft.com/config/rhel/7/prod.repo and then install sudo yum install -y mssql-tools unixODBC-devel the unixODBC-devel is fine. how ever i get this output Loaded plugins: fastestmirror Repository packages-microsoft-com-prod is listed more than once in the configuration Loading mirror speeds from cached hostfile * base: mirror.docker.ru * epel: mirror.telepoint.bg * extras: mirror.docker.ru * updates: mirror.corbina.net No package mssql-tools available. Error: Nothing to do i searched on the part of message that says > Repository packages-microsoft-com-prod is listed more than once in the > configuration however i am not sure but i think i got the same in previous server and every thing installed fine. any way i did some procedure suggested for that and still i get the same message. this is my yum.repos.d directory CentOS-Base.repo CentOS-Media.repo epel.repo mssql-server.repo CentOS-CR.repo CentOS-Sources.repo epel-testing.repo CentOS-Debuginfo.repo CentOS-Vault.repo microsoft-prod.repo CentOS-fasttrack.repo CentOS-x86_64-kernel.repo msprod.repo msprod.repo is the one.
