ubuntu13 apt-get安裝nagios

參考文章:http://nagios-cn.sourceforge.net/nagios-cn/beginning.html#quickstart-ubuntu

--快速安裝nagios

查看 nagios3的版本號

apt-cache showpkg nagios3

安裝nagios

apt-get install  nagios3

會提示安裝sendmail,然后提示你輸入nagios的密碼

安裝好后

http://ip/nagios3/

賬戶nagiosadmin

密碼安裝時候輸入的

#配置文件位置

/etc/nagios3

################常用命令#################

php網頁位置
/usr/share/nagios3/htdocs
圖標位置
/usr/share/nagios/htdocs/p_w_picpaths/logos/logos
配置文件位置
/etc/nagios3/

創建一個nagiosadmin的用戶用于Nagios的WEB接口登錄。記下你所設置的登錄口令，一會兒你會用到它。

htpasswd -c /etc/nagios3/htpasswd.users nagiosadmin

重啟Apache服務以使設置生效。

/etc/init.d/apache2 reload

驗證Nagios的樣例配置文件

/usr/sbin/nagios3 -v /etc/nagios3/nagios.cfg

如果沒有報錯，可以啟動Nagios服務

/etc/init.d/nagios3 restart

#目錄在/etc/nagios3/

#/etc/nagios3/conf.d

首先要修改的就是模版文件否則就會有問題

/etc/nagios3/conf.d 目錄中

generic-host_nagios2.cfg        是主機模版

generic-service_nagios2.cfg    服務模版

hostgroups_nagios2.cfg         主機分組文件

timeperiods_nagios2.cfg         執行計劃的時間

contacts_nagios2.cfg             聯絡方法

#--------------------------------------------------------------------------

#參考手冊: http://nagios-cn.sourceforge.net/nagios-cn/beginning.html#quickstart-ubuntu

#然后我們加入自己的配置文件到里面 例如  switch.cfg 交換機的

#1.首先修改主機模版文件generic-host_nagios2.cfg  

#2.修改 服務模版generic-service_nagios2.cfg  
#3.修改switch.cfg文件

加入

#1. Define a template for switches that we can reuse(交換機的模版文件)
define host{
   name            generic-switch    ; The name of this host template
   use            generic-host    ; Inherit default values from the generic-host template
   check_period        24x7        ; By default, switches are monitored round the clock
   check_interval        5        ; Switches are checked every 5 minutes
   retry_interval        1        ; Schedule host check retries at 1 minute intervals
   max_check_attempts    10        ; Check each switch 10 times (max)
   check_command        check-host-alive    ; Default command to check if routers are "alive"
   notification_period    24x7        ; Send notifications at any time
   notification_interval    30        ; Resend notifications every 30 minutes
   notification_options    d,r        ; Only send notifications for specific host states
   contact_groups        admins        ; Notifications get sent to the admins by default
   register        0        ; DONT REGISTER THIS - ITS JUST A TEMPLATE
   }
#2.在 Create a service to PING to switch

define service{
   use            generic-service    ; Inherit values from a template
   hostgroup_name    switches ; The name of the hostgroup the service is associated with
   service_description    PING        ; The service description
   check_command        check_ping!200.0,20%!600.0,60%    ; The command used to monitor the service
   normal_check_interval    5        ; Check the service every 5 minutes under normal conditions
   retry_check_interval    1        ; Re-check the service every minute until its final/hard state is determined
   }

#在 3. switch.cfg 交換機的配置加入交換機

define host{
   use        generic-switch        ; Inherit default values from a template(使用模版并且使用默認值)
   host_name    4F-cisco-3560G        ; The name we're giving to this switch  (交換機名稱)
 # parents        4f-FortiGate200B  ;定義上級節點        
   alias        cisco 3560G Switch    ; A longer name associated with the switch  (全名,別名)
   address        192.168.1.254        ; IP address of the switch   (IP 地址)
   icon_p_w_picpath       switch50.jpg  ;圖標
   statusmap_p_w_picpath  cat2900.gd2   ;地圖顯示圖標    
   hostgroups    switches        ; Host groups this switch is associated with  (主機加入的編組)
   }

#高級的大家自己玩,就是帶大家入門,下一期入門一下cacti安裝

#------------------------------windows主機監控

#1.

define host{
   use        windows-server    ; Inherit default values from a template
   host_name    erp; The name we're giving to this host
   alias        HERP; A longer name associated with the host
   parents        4F-cisco-3560G  ;定義上級節點 影響顯示地圖
   address        192.168.1.8; IP address of the host
   icon_p_w_picpath       windows_server.jpg
   statusmap_p_w_picpath  win40.gd2    
   }

#2.加入檢測服務

define service{
   use            generic-service
   hostgroup_name        erp
   service_description    NSClient++ Version
   check_command        check_nt!CLIENTVERSION
   }

define service{
   use            generic-service
   hostgroup_name        erp
   service_description    Uptime
   check_command        check_nt!UPTIME
   }

# Create a service for monitoring CPU load
# Change the host_name to match the name of the host you defined above
#檢查cpu平均5分鐘負載,超過90%報警
define service{
   use            generic-service
   hostgroup_name        erp
   service_description    CPU Load
   check_command        check_nt!CPULOAD!-l 5,80,90
   }
# Create a service for monitoring memory usage
# Change the host_name to match the name of the host you defined above
#檢查內存使用
define service{
   use            generic-service
   hostgroup_name       erp
   service_description    Memory Usage
   check_command        check_nt!MEMUSE!-w 80 -c 90
   }
# Create a service for monitoring C:\ disk usage
# Change the host_name to match the name of the host you defined above
#檢查磁盤空間
define service{
   use            generic-service
   hostgroup_name        erp
   service_description    C:\ Drive Space
   check_command        check_nt!USEDDISKSPACE!-l c -w 80 -c 90
   }
