Thanks, Marcel
I found the issue, the file /usr/local/nagios/var/objects.cache lose write permission. So new added nodes can't write into this file. Now, all nodes are showed on nagios page. I killed all nagios processes, then execute "/etc/init.d/nagios start", still found many nagios processes. Faint~

I exectue "/etc/init.d/nagios reload" every time after edit something.

Run "service nagios status", only one daemon is running. But execute "ps -ef |grep nagios.cfg", the process number and pid are always different. Is this issue ?
Yes, that's it! You have several nagios processes that are sons of the PID == 1.
Do a /etc/init.d/nagios stop and execute that ps -fu nagios again to see that there is remaining nagios processes that are sons of the PID == 1.
Then you kill'em all and start fresh.

There are a few possibilities that come to mind --
- You haven't reloaded or restarted nagios since adding them
- The file you're adding them to isn't parsed by nagios (i.e. a cfg_file or in a cfg_dir in nagios.cfg). (run /path/to/nagios -v /path/to/nagios.cfg and see if the numbers presented are reasonable).
- If you have authentication enabled, the user you log in as is not a contact for the hosts in question.
- You have multiple nagios daemons running at the same time and there is contention over the status file.
