监控软件 nagios web修改服务

　　通过web界面修改某个服务时报错
例如对某个服务进行临时安排其执行时间,或者不让它发警告,web页面上都有这样的设置.但是常常会有错误信息如下:

Could not open command file '/usr/local/nagios/var/rw/nagios.cmd' for update! The permissions on the external command file and/or directory may be incorrect. Read the FAQs on how to setup proper permissions. An error occurred while attempting to commit your command for processing.

关于这部分在nagios.cfg中有下面的内容

# EXTERNAL COMMAND FILE # This is the file that Nagios checks for external command requests. # It is also where the command CGI will write commands that are submitted # by users, so it must be writeable by the user that the web server # is running as (usually 'nobody').  Permissions should be set at the # directory level instead of on the file, as the file is deleted every # time its contents are processed. 这段话的核心意思是apache的运行用户要有对文件写的权限.权限应该设置在目录上,因为每次文件的内容被处理后文件就会被删掉 command_file=/usr/local/nagios/var/rw/nagios.cmd

将apache2运行的用户apache加到nagios组就应该可以了的
