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 首先看一下你的进程apache的进程是什么用户运行我的机器是daemon #ps -ef | grep http root 50297 1 0 21:42 ? 00:00:00 /usr/local/apache//bin/httpd -k startdaemon 50298 50297 0 21:42 ? 00:00:00 /usr/local/apache//bin/httpd -k startdaemon 50299 50297 0 21:42 ? 00:00:00 /usr/local/apache//bin/httpd -k startdaemon 50300 50297 0 21:42 ? 00:00:00 /usr/local/apache//bin/httpd -k startdaemon 50301 50297 0 21:42 ? 00:00:00 /usr/local/apache//bin/httpd -k startdaemon 50425 50297 0 21:43 ? 00:00:00 /usr/local/apache//bin/httpd -k startroot 50909 3194 0 22:02 pts/1 00:00:00 grep http 注意这里指的是守护进程而不是root运行的那个起始进程。然后怎么做呢如果你运行的nagios进程的用户是nagios,组也是nagios,则:usermod -G nagios daemonchmod gs /path/to/nagiosdir/var/rw转载于:https://www.cnblogs.com/Yongzhouunknown/p/4885749.html
