--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/p_w_picpaths/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_p_w_picpath switch50.jpg ;图标
statusmap_p_w_picpath 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_p_w_picpath windows_server.jpg
statusmap_p_w_picpath 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
}
# Create a service for monitoring the uptime of the server
# Change the host_name to match the name of the host you defined above
#检查开机时间
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
#检查cpu平均5分钟负载,超过90%报警
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
#检查内存使用
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
#检查磁盘空间
define service{
use generic-service
hostgroup_name erp
service_description C:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l c -w 80 -c 90
}
define service{
use generic-service
host_name mail
service_description D:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l d -w 80 -c 90
}
