在nconf向导的时候报如下错误：
copy config file (.file_accounts.php) failed
copy config file (authentication.php) failed
copy config file (main.php) failed
copy config file (mysql.php) failed
copy config file (nconf.php) failed
解决方案：chown -R nagios.nagios config/ temp/ static_cfg/ output/ 这个权限之前按照网上给的apache用户，导致此处failed.
==================================
执行NConf的 Generate Nagios config 时候, 需要拷贝nagios/bin/nagios文件到nconf/bin 目录下，而且需要设置权限：
Chown apache:apache bin/nagios
Chmod +x bin/nagios
