In Centos7, AMS5.0 after the service is started, can not find Server

Adobe media server is officially supported only on CentOS...The latest release of AMS 5.0.6 has centos 6.3 x64 as recommended platform for linux. However i have seen quite a few people installing it on other unix variants too...Please use at your own risk...BTW, CentOS is a variant of redhat...

Please see if the following link helps you...

Is CentOS exactly the same as RHEL? - Unix & Linux Stack Exchange

if you still insist on trying out AMS on CentOS 7 then do it at your own risk and the procedure to install AMS on cewntos 7 would be to modify the install shell script i.e installAMS and add your centos release to it in following function

# check distribution

check_distro () { ...}

e.g add the following line

cd_check "CentOS Linux release 7" /etc/redhat-release centos-7-i686

to the function inside that shell script file.
