四、配置Nagios的WEB用户界面

　1.配置/etc/httpd/conf.d/nagios.conf文件 #前提已经安装上述步骤执行了 make install-webconf

# SAMPLE CONFIG SNIPPETS FOR APACHE WEB SERVER
#
# This file contains examples of entries that need
# to be incorporated into your Apache web server
# configuration file. Customize the paths, etc. as
# needed to fit your system.
#可以参考此配置文件来配置

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"

<Directory "/usr/local/nagios/sbin">
# SSLRequireSSL
Options ExecCGI
AllowOverride None
<IfVersion >= 2.3>
<RequireAll>

# Require host 127.0.0.1

Require valid-user
</IfVersion>
</Directory>

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

<Directory "/usr/local/nagios/share">
# SSLRequireSSL

<IfVersion >= 2.3>
<RequireAll>

# Require host 127.0.0.1

</RequireAll>
</IfVersion>
<IfVersion < 2.3>
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1

AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</IfVersion>
</Directory>

 

登录http://IP/nagios输入用户名密码查看是否正常。

3.配置守护进程启动：/etc/xinetd.d/nrpe

# default: on

# description: NRPE (Nagios Remote Plugin Executor)

service nrpe

{

         flags           = REUSE

         socket_type     = stream   

     port        = 5666   

         wait            = no

         user            = nagios

     group       = nagios

         server          =  /usr/local/nagios/bin/nrpe

         server_args     = -c  /usr/local/nagios/etc/nrpe .cfg --inetd

     log_type        =  file  /tmp/nrpe .log

         log_on_failure  += USERID

         disable         = no

     only_from       = 10.124.151.248

}

 

 
   第二部分：Ndoutils的安装 
     
     
     
     
     
   3.检查和配置mysql配置文件/etc/my.cnf

   4.设置ndo2db启动方式：

            #源码中有多种方式可以启动nd02db，这里设置成init方式管理 
            
            
            cp

            #修改/etc/init.d/ndo2db 
            
            
            修改 
            
            
            NDO2DB_BIN= 
            /usr/local/nagios/bin/ndo2db-4x 
            　 
            
            
            #设置成开机自启
