nagios web界面提示
It appears as though you do not have permission to view information for any of the services you requested...
打开cgi.cfg配置文件，里面有个参数:
use_authentication=1
为了保障系统的安全性，nagios设置了这个参数，默认为1,改为0即可

装了几次，换了几个版本的系统，脑袋都大了，终于解决了
nrpe在 ./configure时提示
checking for SSL... configure: error: Cannot find ssl libraries
把openssl-devel装上就可以了

Service Commands 中Enable notifications for this service时报错
Sorry Dave, I can't let you do that...
It seems that you have chosen to not use the authentication functionality of the CGIs.
I don't want to be personally responsible for what may happen as a result of allowing unauthorized users to issue commands to Nagios,so you'll have to
disable this safeguard if you are really stubborn and want to invite trouble.
Read the section on CGI authentication in the HTML documentation to learn how you can enable authentication and why you should want to.
修改cgi.cfg文件
修改use_authentication=1 (默认) ，如果没有添加，重启nagios服务。

is not allowed to connect to this mysql server
1.server(nagios服务端192.168.0.132)
#/usr/local/nagios/libexec/check_mysql -H 192.168.0.207 -u root -p xukixu
此时可能会出现错误：Host '192.168.0.132' is not allowed to connect to this MySQL server
因此只要在客户端做个mysql授权用户访问即可
2、client(客户端192.168.0.207)
#mysql -uroot -pabcd
mysql>grant all privileges on *.* to root@192.168.0.132 identified by 'abcd;
mysql>flush privileges;
mysql>quit;

The requested URL /nagios/cgi-bin/statusmap.cgi was not found on this server
解决方案，确定安装下面的包。
libgd
libgd-devel
libpng
libpng-devel
libjpeg
libjpeg-devel
zlib
zlib-devel
回到nagios安装时解压开的目录
Bash代码
make devclean
./configure --with-gd-lib=/usr/lib --with-gd-inc=/usr/include
make all
make install
make install-init
make install-config
make install-commandmode
make install-webconf
重新回到nagios的sbin目录查看几个cgi脚本有没有生成。
