配置pnp4nagios

下載地址：

Rrtool地址：httposs.oetiker.chrrdtool

Pnp地址：http://docs.pnp4nagios.org/

需要 rrtool 支援

yum install rrdtool gd gd-devel php-gd

安裝pnp4nagios

tar zxvf pnp4nagios-0.6.21.tar.gz
cd pnp4nagios-0.6.21
./configure

報錯

configure:error: Perl Module Time::HiRes not available

解決方法

yum installperl-Time-HiRes

make 
make install
make install-config 
make install-init
make install-webconf  //apache伺服器需要

安裝目錄： /usr/local/pnp4nagios

建立配置檔案

cd  /usr/local/pnp4nagios/etc
mv misccommands.cfg-sample  misccommands.cfg
mv nagios.cfg-sample nagios.cfg
mv rra.cfg-sample rra.cfg
cd /usr/local/pnp4nagios/etc/pages/
mv web_traffic.cfg-sample web_traffic.cfg
cd ../check_commands
mv check_all_local_disks.cfg-sample  check_all_local_disks.cfg
mv check_nrpe.cfg-sample  check_nrpe.cfg
mv check_nwstat.cfg-sample  check_nwstat.cfg
 

service npcd restart

修改nagios.cfg

 
process_performance_data=1                             //由0改為1 
host_perfdata_command=process-host-perfdata            //前面的註釋拿掉 
service_perfdata_command=process-service-perfdata      //註釋拿掉

修改commands.cfg

# 'process-host-perfdata' command definition
define command{
	command_name	process-host-perfdata
	command_line	/usr/local/pnp4nagios/libexec/process_perfdata.pl  -d HOSTPERFDATA
	}


# 'process-service-perfdata' command definition
define command{
	command_name	process-service-perfdata
	command_line	/usr/local/pnp4nagios/libexec/process_perfdata.pl
	}
 

修改配置檔案templates.cfg,新增以下內容

 
define host { 
       name       hosts-pnp 
       register   0 
       action_url /pnp4nagios/graph?host=$HOSTNAME$
       process_perf_data              1 
} 
define service { 
       name       srv-pnp 
       register   0 
       action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$ 
       process_perf_data              1 
}

修改伺服器配置檔案localhost.cfg

 
define host{ 
       use                    linux-server,hosts-pnp 
       host_name              localhost 
       alias                  localhost 
       address                127.0.0.1 
       } 
 
define service{ 
       use                            local-service,srv-pnp 
       host_name                      localhost 
       service_description            PING 
       check_command                   check_ping!100.0,20%!500.0,60% 
       }

配置apache

pnp4nagios4.10版本apache至此不需要做任何配置，直接就可以訪問了，升級到0.6後發現必須rewrite了

安裝pnp4nagios 時使用make install-webconf

這個會在/etc/httpd/ conf.d/中生成pnp4nagios.conf檔案將其複製到http.conf檔案中

# SAMPLE CONFIG SNIPPETS FOR APACHE WEBSERVER
 
Alias /pnp4nagios"/usr/local/pnp4nagios/share"
 
<Directory"/usr/local/pnp4nagios/share">
     AllowOverride None
     Order allow,deny
     Allow from all
     #
     # Use the same value as defined in nagios.conf
     #
     AuthName "Nagios Access"
     AuthType Basic
     AuthUserFile/usr/local/nagios/etc/htpasswd.users //根據自身配置路徑設定
     Require valid-user
         <IfModulemod_rewrite.c>
                   #Turn on URL rewriting
                   RewriteEngineOn
                   OptionssymLinksIfOwnerMatch
                   #Installation directory
                   RewriteBase/pnp4nagios/
                   #Protect application and system files from being viewed
                   RewriteRule"^(?:application|modules|system)/" - [F]
                   #Allow any files or directories that exist to be displayed directly
                   RewriteCond"%{REQUEST_FILENAME}" !-f
                   RewriteCond"%{REQUEST_FILENAME}" !-d
                   #Rewrite all other URLs to index.php/URL
                   RewriteRule"^.*$" "index.php/$0" [PT]
         </IfModule>
</Directory>

修改/etc/nagios/cgi.cfg裡的使用者名稱是無效的

#default_user_name=guest

設定項，取消註釋，修改為

default_user_name=nagiosadmin

service nagios restart
service httpd restart

進入後點擊小太陽出現PNP4Nagios Environment Tests

將/usr/local/pnp4nagios/share 中的install.php 刪除即可

點選小太陽出現

解決方案：

預設的php是apache的組，而我的httpd.conf中將httpd的服務改成了nagios使用者和組

所以將php許可權改為nagios 即可

cd /var/lib
chown -R nagios.nagios php/
