--快速安装nagios

查看 nagios3的版本号

apt-cache showpkg nagios3

安装nagios

apt-get install  nagios3

会提示安装sendmail,然后提示你输入nagios的密码

安装好后

http://ip/nagios3/

账户nagiosadmin

密码安装时候输入的

#配置文件位置

/etc/nagios3

################常用命令#################

php网页位置
/usr/share/nagios3/htdocs
图标位置
/usr/share/nagios/htdocs/images/logos/logos
配置文件位置
/etc/nagios3/

创建一个nagiosadmin的用户用于Nagios的WEB接口登录。记下你所设置的登录口令，一会儿你会用到它。

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

重启Apache服务以使设置生效。

/etc/init.d/apache2 reload

验证Nagios的样例配置文件

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

如果没有报错，可以启动Nagios服务

/etc/init.d/nagios3 restart

##                                  Nagios配置                                    ##

#######################################

#目录在/etc/nagios3/

#/etc/nagios3/conf.d

首先要修改的就是模版文件否则就会有问题

/etc/nagios3/conf.d 目录中

generic-host_nagios2.cfg        是主机模版

generic-service_nagios2.cfg    服务模版

hostgroups_nagios2.cfg         主机分组文件

timeperiods_nagios2.cfg         执行计划的时间

contacts_nagios2.cfg             联络方法

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

#参考手册: http://nagios-cn.sourceforge.net/nagios-cn/beginning.html#quickstart-ubuntu

#然后我们加入自己的配置文件到里面 例如  switch.cfg 交换机的

#1.首先修改主机模版文件generic-host_nagios2.cfg  

#2.修改 服务模版generic-service_nagios2.cfg  
#3.修改switch.cfg文件

加入

#1. Define a template for switches that we can reuse(交换机的模版文件)
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 交换机的配置加入交换机

define host{
   use        generic-switch        ; Inherit default values from a template(使用模版并且使用默认值)
   host_name    4F-cisco-3560G        ; The name we're giving to this switch  (交换机名称)
 # parents        4f-FortiGate200B  ;定义上级节点        
   alias        cisco 3560G Switch    ; A longer name associated with the switch  (全名,别名)
   address        192.168.1.254        ; IP address of the switch   (IP 地址)
   icon_image       switch40.jpg  ;图标
   statusmap_image  cat2900.gd2   ;地图显示图标    
   hostgroups    switches        ; Host groups this switch is associated with  (主机加入的编组)
   }

#高级的大家自己玩,就是带大家入门,下一期入门一下cacti安装

#------------------------------windows主机监控

#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  ;定义上级节点 影响显示地图
   address        192.168.1.8; IP address of the host
   icon_image       windows_server.jpg
   statusmap_image  win40.gd2    
   }

#2.加入检测服务

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