'it failed when tried to get host name using python
socket.getfqdn()
and the result is ok,return sjs_88_78 and then
socket.gethostbyname('sjs_88_78')
it will socket.gaierror: [Errno -2] Name or service not known is it env issue?how to fix it?
BTW,i run on Red Hat Enterprise Linux Server release 6.6 (Santiago)
Solution 1:[1]
Is it possible that there are some wrong characters in the name in the second command?
gaierror stands for "getadressinfo error". I saw this error in a case when I had some wrong character in my hostname. In my case that was an additional space that I wrongly copied and paste... Not sure that it's your case as well... but just for information.
Also, it's interesting if a invisible return character could provoke this. Like difference between Unix and Windows return character...

It could be that you don't have a proper address-to-host mapping set up on your server. From the Python socket docs:
"If you want to know the current machine’s IP address, you may want to use gethostbyname(gethostname()). This operation assumes that there is a valid address-to-host mapping for the host, and the assumption does not always hold."
