Misconfiguration of hostname causes the application to fail to start problem handling

OS:Red Hat Enterprise Linux Server release 6.3 (Santiago)

Middleware: weblogic 10.3.6

After the application administrator reports, there is a server in the test environment, and all services cannot be started. The error message is as follows:

After logging in to the server, you see the prompt that indicates that the user name is abnormal

Check that the / etc/hosts and / etc/sysctl/network files are configured properly.

Execute uname-n to view user name exception

[root@=I] # uname-nasty I [root@=I ~] #

At this point, further check that the kernel configuration file has been modified, and the check file finds that the configuration is abnormal:

[root@=I ~] # more / proc/sys/kernel/hostname=I [root@=I ~] #

After modifying the file / proc/sys/kernel/hostname, reconnect the session and prompt that the hostname is normal

[root@=I ~] # echo mvxl1088 > / proc/sys/kernel/hostname [root@=I ~] # [root@=I ~] # [root@=I ~] # more / proc/sys/kernel/hostnamemvxl1088 [root@=I ~] # exit

Try to start the service, the service can start normally.
