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
