what do selinux can't apply partial context to unlabeled file /usr/local/nagios/sbin/
 

Instead of disabling SELinux or setting it to permissive mode, you can use the following command to run the CGIs under SELinux enforcing/targeted mode:

[root@localhost ~]# chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/

chcon: can't apply partial context to unlabeled file /usr/local/nagios/sbin/

how to solve this problem?

when i provide
i tried in many ways

Try editing /etc/sysconfig/selinux and changing it to 'permissive', then
Once rebooted you probably want to add the file context using
then

A partial context can't be set if a file is unlabeled. So without setting SELinux to permissive, without autorelabeling and without first setting a fcontext, I would first run 'restorecon -FRvvn /usr/local/nagios/sbin/' to make it show what it would set the context to. (It'll probably default to system_u:object_r:usr_t.) If that's the case then you should be able to 'chcon -u system_u -r object_r -t usr_t -R /usr/local/nagios' and 'chcon -u system_u -r object_r -t httpd_sys_script_exec_t /usr/local/nagios/sbin/*.cgi' before storing changes with 'semanage'. Also note that you shouldn't 'semanage fcontext' "httpd_sys_content_t" on /usr/local/nagios/sbin if the directory contains more than only CGI files and to apply to a context to CGI files alone IIRC the right invocation would be
'semanage fcontext -a -f -- -t httpd_sys_content_t /usr/local/nagios/sbin/.*\.cgi'. Running 'semanage fcontext -l |grep 'local/nagios/sbin';' afterwards should show if it stuck.

You are getting the error probably because you have disabled SElinux. So all labels are removed. This is shown by your ls command as well since there is not a period after the permissions. (e.g. rwxrwxrwx.) Since the files do not have labels, how can you add a label. You will have to enable selinux and then relable all files (auto way is to reboot) note this may take a while. After it is re enabled, you should be able to set the labels again.
