Thanks for your help!
I downloaded binary package from http://aerospike.com/download/server/latest/artifact/tgz, init runs fine, but ./bin/aerospike start failed with: start failed due to an error. /x/home/aerospike-server/bin/asd: /lib64/libc.so.6: version `GLIBC_2.7’ not found (required by /x/home/aerospike-server/bin/asd)
The libc.so verison i have is: GNU C Library stable release version 2.5
I wonder, should I download the required version of libc.so or what?
Since the 3.x release we have dropped support for Redhat 5; as a result, many of our tools no longer work on Redhat 5 either. It may work if you upgrade libc. Are you able to use another OS such as Redhat 6?
