添加cfg_file=/usr/local/nagios/etc/objects/hosts.cfg和cfg_file=/usr/local/nagios/etc/objects/services.cfg
注释该行cfg_file=/usr/local/nagios/etc/objects/localhost.cfg

[root@centos6 Nagios-Server]#/etc/init.d/nagios reload
具体操作是这样先添加主机、再添加服务、然后添加命令；检查配置最后重载Nagios服务。
备注：可能会出现的故障（有些是关于NRPE错误）
1，登录web界面的时候提示错误：
解决：vim /usr/local/nagios/etc/cgi.cfg 把所有关于nagiosadmin改成你自己添加的用户名，重启服务即可。
2，command ‘check_Passwd‘ not define
解决：到 /usr/local/nagios/etc/objects/ commands.cfg 把它定义好就可以了。
3，Connction refurse host
解决：先cd /usr/local/nagios/libexec 下，使用 ./check_nrpe -H 192.168.0.150 -c check_ping 或者./check_nrpe -H 127.0.0.1 -c check_ping
如果还是提示Connction refurse host；接下来查看NRPE有没有启动：netstat -lntup |grep nrpe 如果没有启动执行
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d 然后再执行./check_nrpe -H 192.168.0.150 -c check_ping
4，NRPE command ‘check_disk‘ not define
解决：先ps -ef |grep nrpe
pkill nrpe
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
ps -ef |grep nrpe
然后再获取./check_nrpe -H 192.168.0.150 -c check_disk
5，CHECK_NRPE: Error - Could not complete SSL handshake.
解决：vi /usr/local/nagios/etc/nrpe.cfg +79
allowed_hosts=127.0.0.1,192.168.0.22
ps -ef |grep nrpe
pkill nrpe
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
ps -ef |grep nrpe
6，NRPE: Unable to read output
解决：./check_nrpe -H 192.168.0.150 -c check_emm 如果还提示NRPE: Unable to read output然后
直接到里面/usr/local/nagios/libexec/check_memory.pl -w 6% -c 3% 如果提示Permission denied
说明 /usr/local/nagios/libexec/check_memory.pl -w 6% -c 3% 没有执行的权限
chmod +x /usr/local/nagios/libexec/check_memory.pl -w 6% -c 3%
