[root@nagios nagios]#  tar zxvf nagios-4.0.8.tar.gz

[root@nagios nagios-4.0.8]# make all

[root@nagios nagios-4.0.8]#   make install

[root@nagios nagios-4.0.8]#  make install-init

[root@nagios nagios-4.0.8]#   make install-commandmode

[root@nagios nagios-4.0.8]#   make install-config         

[root@nagios nagios-4.0.8]# make install-webconf    

[root@nagios nagios-4.0.8]#  make install-exfoliation

[root@nagios nagios-4.0.8]#   make install-classicui

2：安裝插件  nagios-plugins-2.0.3.tar.gz   http://www.nagios.org/download/plugins

./configure&&make&&make install

ln -s /usr/local/nagios /etc/nagios

個(gè)性化的插件都拷貝到/etc/nagios/libexec 下

3：安裝iostat_plugins 需要如下rpm包包

[root@nagios iostat_plugins]#  ls -h
perl-Class-Accessor-0.31-1.el5.rf.noarch.rpm   perl-Params-Validate-0.89-1.el5.rf.i386.rpm
perl-Config-Tiny-2.12-1.el5.rf.noarch.rpm      perl-Regexp-Common-2.120-1.2.el5.rf.noarch.rpm
perl-Math-Calc-Units-1.06-1.el5.rf.noarch.rpm

如下插件都可以網(wǎng)上找 主要是check_traffic.sh

cp check_memory.pl check_iostat check_file_des check_inode check_netstat check_traffic.sh /usr/local/nagios/libexec
chmod 755 /usr/local/nagios/libexec/check_memory.pl
chmod 755 /usr/local/nagios/libexec/check_iostat
dos2unix /usr/local/nagios/libexec/check_memory.pl
dos2unix /usr/local/nagios/libexec/check_iostat

使用check_traffic.sh之前需要安裝snmp包snmpwalk

 rpm -ivh net-snmp-utils-5.3.2.2-9.el5_5.1.i386.rpm

 mkdir -p /var/tmp/nagios && chown -R nagios.nagios /var/tmp/nagios

 例子：如何獲取交換機(jī)的端口信息

/usr/local/nagios/libexec/check_traffic.sh -V 2c -C 3550b -H 172.16.40.9 -L  

4:優(yōu)化部分

[root@nagios etc]#  cd /etc/nagios/etc

[root@nagios etc]# htpasswd -c /usr/local/nagios/etc/htpasswd.users admin
New password:
Re-type new password:
Adding password for user admin

編輯cgi.cfg文件，替換nagiosadmin 為admin

/etc/init.d/nagios start

/etc/init.d/httpd start

5:繪圖PNP

http://docs.pnp4nagios.org/pnp-0.6/dwnld 

下載：pnp4nagios-0.6.24.tar.gz             文檔部分     http://docs.pnp4nagios.org/pnp-0.6/start 

 PNP是一個(gè)Nagios插件 ***能數(shù)據(jù)進(jìn)行分析,并將它們存儲(chǔ)自動(dòng)RRD-databases

RRDtool是開(kāi)源行業(yè)標(biāo)準(zhǔn),可以提供高性能數(shù)據(jù)記錄時(shí)間序列數(shù)據(jù)和圖形繪制系統(tǒng)

下載鏈接：http://oss.oetiker.ch/rrdtool/pub/?M=D

此處使用rrdtool-1.2.12.tar.gz

[root@nagios rrdtool-1.2.12]#  ./configure

[root@nagios rrdtool-1.2.12]# make all &&make install

[root@nagios pnp4nagios-0.6.24]# ls /usr/local/rrdtool-1.2.12/  安裝好的目錄

[root@nagios ~]#    cd pnp4nagios-0.6.24

[root@nagios pnp4nagios-0.6.24]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool=/usr/local/rrdtool-1.2.12/bin/rrdtool

[root@nagios pnp4nagios-0.6.24]# make all

[root@nagios pnp4nagios-0.6.24]#   make install

[root@nagios pnp4nagios-0.6.24]# make install-webconf

[root@nagios pnp4nagios-0.6.24]# make install-config

*** PNP4Nagios sample config files installed ***

Please run 'make install-init' if you want to use
BULK Mode with NPCD

默認(rèn)是運(yùn)行Synchronous Mode 模式，比較浪費(fèi)資源它是每一個(gè)事件將觸發(fā)process-service-perfdata的執(zhí)行

 所以此處使用Bulk mode 批量模式比同步模式更為復(fù)雜但能顯著降低nagios服務(wù)器上的負(fù)載,因?yàn)閿?shù)據(jù)收集器process_perfdata.pl不調(diào)用每個(gè)服務(wù)/主機(jī)檢查。

在批量模式Nagios將數(shù)據(jù)寫(xiě)入一個(gè)臨時(shí)文件中。這個(gè)文件是由process_perfdata進(jìn)行處理。在特定的間隔。Nagios將定期照顧啟動(dòng)和運(yùn)行它

•   首先在nagios.cfg中 啟用收據(jù)收集開(kāi)關(guān)

process_performance_data=1

#
# service performance data
#
service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=15
service_perfdata_file_processing_command=process-service-perfdata-file

#
# host performance data starting with Nagios 3.0
#
host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata
host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$
host_perfdata_file_mode=a
host_perfdata_file_processing_interval=15
host_perfdata_file_processing_command=process-host-perfdata-file

• 編輯command.cfg

  define command{
         command_name    process-service-perfdata-file
         command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/service-perfdata
  }
  
  define command{
         command_name    process-host-perfdata-file
         command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/host-perfdata
  }

6: 調(diào)試

http://192.168.10.100/pnp4nagios/    提示404錯(cuò)誤

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

 在安裝光盤(pán)上查詢(xún)依次安裝即可，缺啥補(bǔ)啥

[root@nagios CentOS]#  ls *php* | grep gd
php53-gd-5.3.3-1.el5.i386.rpm
php-gd-5.1.6-27.el5_5.3.i386.rpm

 然后重啟WEB 刷新通過(guò)。

Your environment passed all requirements. Remove or rename the /usr/local/pnp4nagios/share/install.php file now.

                                         cd /usr/local/pnp4nagios/share/

[root@nagios share]#   mv install.php install.php.bak

• 編輯模板新增vim templates.cfg

define host {
   name       host-pnp
   action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_' class='tips' rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_
   register   0
}

define service {
   name       srv-pnp
   action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$' class='tips' rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=$SERVICEDESC$
   register   0
}

在LINUX 被監(jiān)控端安裝nagios-plugins-2.0.3   nrpe-2.15.tar.gz

運(yùn)行方式：

 /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
