0.安装之前先安装#yum install gcc
1.checking for a BSD-compatible install... /usr/bin/install -c

checking whether build environment is sane... configure: error: newly created file is older than distributed files!
Check your system clock
解决办法：#/usr/sbin/ntpdate asia.pool.ntp.org>>/var/log/ntpdate.log

2.安装nrpe，编译的时候提示以下信息
checking for SSL headers... configure: error: Cannot find ssl headers

原因是缺少openssl-devel包，
[root@localhost nrpe-2.12]# yum -y install openssl-devel
3.[root@localhost nrpe-2.12]# service xinetd restart
xinetd: 未被识别的服务
解决办法：
[root@localhost nrpe-2.12]# yum -y install xinetd*
