最近nagios出现以上问题，
解决方法：
将nagios和apache放到一个组nagcmd，问题解决
此问题可能与我修改了一次nagios数组有关系

[root@localhost etc]# id nagios
uid=607(nagios) gid=605(nagios) groups=605(nagios),607(nagcmd)
[root@localhost etc]# id apache
uid=48(apache) gid=48(apache) groups=48(apache),607(nagcmd)


另外修改完后，还需要重启一下apache
刚开始修改完毕后。我没有重启apache，还是出现问题。重启后问题解决



还有一个方法是：
手动修改它的权限改成777
/opt/nagios/var/rw/nagios.cmd
重启nagios还要修改权限

还有一个思路是

vim nagios.cfg
# NAGIOS GROUP
# This determines the effective group that Nagios should run as. 
# You can either supply a group name or a GID.

nagios_group=nagcmd


将这里的nagios的数组改成nagcmd
无论怎么重启，都没问题
