六大Nagios常见问题解决办法

Nagios常见问题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。

Nagios常见问题2:

ReadthesectiononCGIauthenticationintheHTMLdocumentationtolearnhowyoucanenableauthenticationandwhyyoushouldwantto.

原因 : 未开启认证

解决：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

Nagios常见问题3:

Ifyoubelievethisisanerror,checktheHTTPserverauthenticationrequirementsforaccessingthisCGI 

andchecktheauthorizationoptionsinyourCGIconfigurationfile.

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

Nagios常见问题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 

makeall 

makeinstall 

makeinstall-init 

makeinstall-config 

makeinstall-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

Nagios常见问题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
