Nagios常見問題

發布時間: 2012/7/31 19:35:19

　問題1:
　　It appears as though you do not have permission to view information for any of the hosts you requested
　　臨時解決:
　　sed -i 's/use_authentication=1/use_authentication=0/g' /usr/local/nagios/etc/cgi.cfg
　　(取消了認證可以瀏覽主機狀態但是無法在 nagios web端執行外部命令 )
　　解決:
　　登陸 nagios web接口的用戶
　　需要和 /usr/local/nagios/etc/cgi.cfg 里面配置的用戶匹配
　　沒有可以手動添加用逗號隔開
　　問題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 : 未開啟認證開啟認證可解決問題
　　編輯文件 /usr/local/nagios/etc/cgi.cfg
　　將 use_authentication 值設成1 (0/1 關閉/開啟)
　　use_authentication=1
　　并重啟 nagios
　　service nagios restart
　　問題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 : 認證用戶不正確
　　開啟認證認證的用戶必須是 cgi.cfg 配置文件里有的默認是 nagiosadmin
　　如果你新建的其他用戶需要添加進去多用戶用逗號分開
　　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
　　問題4:
　　調用外部命令錯誤可能權限不夠
　　解決:
　　臨時解決:
　　chown -R nagios.nagcmd /usr/local/nagios/var/rw
　　chmod -R 777 /usr/local/nagios/var/rw
　　為什么說臨時解決 ? 因為重啟nagios后權限會還原還是沒權限執行
　　解決:
　　在安裝 nagios 時就要把用戶選對然后再安裝
　　./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 權限是 nagios.nagios
　　還需要把 web用戶加入到 nagios組里這樣才有權限執行 nagios.cmd
　　問題5: 3D瀏覽錯誤提示下載 statuswrl.cgi
　　解決: 需安裝3D瀏覽插件
　　原因是未安裝支持vrml 3D瀏覽的插件
　　vrml 面向對象的三維造型語言需要安裝 vrml 支持插件才能瀏覽
　　Cortona VRML Client 是一個優秀的VRML瀏覽插件

　　問題6: 查看幫助文檔時無法看到圖片
　　原因 url錯誤
　　圖片源地址 http://nagios_ip/pub/images/reachability1.png
　　實際地址 /usr/local/nagios/share/docs/images/reachability1.png
　　解決
　　配置apache加入別名
　　Alias /pub "/usr/local/nagios/share/docs"
　　apachectl restart
　　重啟apache 問題解決
