nagios常见错误及页面错误

nagios服务器问题1我当时遇到奇怪现象，可以看到首页，链接打不开，检查apache配置，文件权限，后来确认当有部分程序出现奇怪状态，比如权限问题得时候，请关闭SELINUX解决方法:vi /etc/sysconfig/selinux SELINUX=enforcing --> SELINUX=disabled 存盘退出

nagios服务器问题2监控页面出现It appears as though you do not have permission to view information for any of the hosts you requested... If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI and check the authorization options in your CGI configuration file. 1、修改/etc/cgi.cfgvi /usr/local/nagios/cgi.cfg use_authentication=1 #把1修改为0,保存 root@nagios#/etc/init.d/nagios restart

nagios服务器问题3Warning: Return code of 127 for check of service 'Uptime' on host 'winserver' was out of bounds. Make sure the plugin you're trying to run actually exists通常都的plugin没有安装，或者安装位置有问题，我遇到是查看目录：/usr/local/nagios/libexec/libexec、后来将libexec文件往前挪一下就可以了：/usr/local/nagios/libexec.===================================
===================================
常见错误：
问题1:

It appears as though you do not have
permission to view information for any of the hosts you requested

临时解决:

sed -i 's/use_authentication=1/use_authentication=0/g'
/usr/local/nagios/etc/cgi.cfg

(取消了认证 可以浏览主机状态 但是无法在 nagios web端 执行外部命令 )

解决:

登陆 nagios web接口的用户

需要和 /usr/local/nagios/etc/cgi.cfg 里面配置的用户匹配

没有可以手动添加 用逗号隔开

问题2:

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.

原因 : 未开启认证 开启认证可解决问题

编辑文件 /usr/local/nagios/etc/cgi.cfg

将 use_authentication 值设成1 (0/1 关闭/开启)

use_authentication=1

并重启 nagios

service nagios restart

问题3:

It appears as though you do not have
permission to view information for any of the hosts you requested...
If you believe this is an error, check the
HTTP server authentication requirements for accessing this CGI

and check the authorization options in your CGI configuration file.

原因 : 认证用户不正确

开启认证 认证的用户必须是 cgi.cfg 配置文件里有的 默认是 nagiosadmin

如果你新建的其他用户 需要添加进去 多用户用逗号分开

authorized_for_system_information=nagiosadmin

authorized_for_configuration_information=nagiosadmin

authorized_for_system_commands=nagiosadmin

authorized_for_all_services=nagiosadmin

authorized_for_all_hosts=nagiosadmin

authorized_for_all_service_commands=nagiosadmin

authorized_for_all_host_commands=nagiosadmin

如果不是 nagiosadmin 需要到后面添加

例子
authorized_for_system_information=nagiosadmin,admin

问题4:

调用外部命令错误 可能权限不够

解决:

临时解决:

chown -R nagios.nagcmd
/usr/local/nagios/var/rw

chmod -R 777 /usr/local/nagios/var/rw

为什么说临时解决 ? 因为重启nagios后 权限会还原 还是没权限执行

解决:

在安装 nagios 时 就要把用户选对 然后再安装

./configure --with-group=nagios
--with-user=nagios --with-command-group=nagcmd --with-gd-lib=/usr/lib
--with-gd-inc=/usr/include

make all

make install

make install-init

make install-config

make install-commandmode

===

rw\nagios.cmd 权限是 nagios.nagios

还需要把 web用户 加入到 nagios组里 这样才有权限执行 nagios.cmd
问题5: 3D浏览错误 提示下载 statuswrl.cgi
解决: 需安装3D浏览插件
原因是未安装支持vrml 3D浏览的插件
vrml 面向对象的三维造型语言 需要安装 vrml 支持插件才能浏览
Cortona VRML Client 是一个优秀的VRML浏览插件

问题6: 查看帮助文档时 无法看到图片

原因 url错误

图片源地址 http://nagios_ip/pub/images/reachability1.png
实际地址 /usr/local/nagios/share/docs/images/reachability1.png

解决

配置apache加入别名

Alias /pub "/usr/local/nagios/share/docs"

apachectl restart

重启apache 问题解决
