Try a solution:

two。 Check python version 2.6.6

3. Check the / etc/hosts file and restart the network service network restart

4. Check the / etc/sysconfig/network file and restart the network service network restart

5. Check the / etc/resolv.conf file and restart the network service network restart

6. Check the / etc/sysconfig/network-scripts/ifcfg-eth0 file and restart the network service network restart

Check whether port 7182 exists on the 7.scm server machine: netstat-nlp | grep 7182

It's actually DNS reverse parsing.
