Linux---Nagios無法登錄Internal Server Error

今天配置安裝完成Nagios后，始終無法登錄，報錯信息如下

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

于是查看先關日志文件，相關報錯日志可以在Apache中查看

ｖｉ　／var/log/httpd/error_log

或者

ｖｉ　／usr/localapache/logs/error_log

日志提示是驗證報錯，

nagios could not open password file :/usr/local/nagios/etc/htpasswd

無法打開htpasswd文件，于是進入該目錄查看 

cd /usr/local/nagios/etc/htpasswd

原來實際文件為htpasswd.users，漏了users

最后再進入apache中修改httpd.cof文件，在AuthenUserFile 處應填寫地址如下

/usr/local/nagios/etc/htpasswd.users

最后重啟Apache,Nagios，驗證登錄，OK,一點感想，還是老話說的好，小心使得萬年船！

此外提供其他幾個無法登錄的排錯方法:

1.

htpasswd  -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

默認在root用戶下生成的密碼文件權限是root的，記得修改成用戶nagios的

chown -R nagios.nagios /usr/local/nagios/etc/htpasswd.users

2.修改/etc/selinux/config文件中設置SELINUX=disabled

3.在 httpd.conf 后面 加了驗證的

#setting for nagios
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
     AuthType Basic
     Options ExecCGI
     AllowOverride None
     Order allow,deny
     Allow from all
     AuthName "Nagios Access"
     AuthUserFile /usr/local/nagios/etc/htpasswd             //用于此目錄訪問身份驗證的文件
     Require valid-user
</Directory>
Alias /nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
     AuthType Basic
     Options None
     AllowOverride None
        AuthName "Nagios Access"

         AuthUserFile /usr/local/nagios/etc/htpasswd             //用于此目錄訪問身份驗證的文件

         Require valid-user
    
</Directory>

Alias /nagios "/usr/local/nagios/share"

<Directory "/usr/local/nagios/share">

     AuthType Basic

     Options None

     AllowOverride None

     Order allow,deny

     Allow from all

     AuthName "nagios Access"

     AuthUserFile /usr/local/nagios/etc/htpasswd

     Require valid-user

</Directory>

4.有用 htpasswd 有用htpasswd.users的,Apache默認用的驗證文件是htpasswd.users，用別的文件名需要定義

5./usr/local/nagios/etc/cgi.cfg中user 是否為設置密碼帳號的那個帳號
