Nagios常见问题

发布时间: 2012/7/31 19:35:19

　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 agios.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
