發(fā)布時(shí)間: 2012/7/31 19:35:19

　問(wèn)題1:
　　It appears as though you do not have permission to view information for any of the hosts you requested
　　臨時(shí)解決:
　　sed -i 's/use_authentication=1/use_authentication=0/g' /usr/local/nagios/etc/cgi.cfg
　　(取消了認(rèn)證可以瀏覽主機(jī)狀態(tài) 但是無(wú)法在 nagios web端執(zhí)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(méi)有可以手動(dòng)添加用逗號(hào)隔開
　　問(wèn)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(rèn)證開啟認(rèn)證可解決問(wèn)題
　　編輯文件 /usr/local/nagios/etc/cgi.cfg
　　將 use_authentication 值設(shè)成1 (0/1 關(guān)閉/開啟)
　　use_authentication=1
　　并重啟 nagios
　　service nagios restart
　　問(wèn)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(rèn)證用戶不正確
　　開啟認(rèn)證認(rèn)證的用戶必須是 cgi.cfg 配置文件里有的默認(rèn)是 nagiosadmin
　　如果你新建的其他用戶需要添加進(jìn)去多用戶用逗號(hào)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(wèn)題4:
　　調(diào)用外部命令錯(cuò)誤可能權(quán)限不夠
　　解決:
　　臨時(shí)解決:
　　chown -R nagios.nagcmd /usr/local/nagios/var/rw
　　chmod -R 777 /usr/local/nagios/var/rw
　　為什么說(shuō)臨時(shí)解決 ? 因?yàn)橹貑agios后權(quán)限會(huì)還原還是沒(méi)權(quán)限執(zhí)行
　　解決:
　　在安裝 nagios 時(shí) 就要把用戶選對(duì) 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(quán)限是 nagios.nagios
　　還需要把 web用戶加入到 nagios組里這樣才有權(quán)限執(zhí)行 nagios.cmd
　　問(wèn)題5: 3D瀏覽錯(cuò)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?qū)ο蟮娜S造型語(yǔ)言需要安裝 vrml 支持插件才能瀏覽
　　Cortona VRML Client 是一個(gè)優(yōu)秀的VRML瀏覽插件

　　問(wèn)題6: 查看幫助文檔時(shí) 無(wú)法看到圖片
　　原因 url錯(cuò)誤
　　圖片源地址 http://nagios_ip/pub/images/reachability1.png
　　實(shí)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(wèn)題解決
