【Nagios】Linux監(jiān)控軟件安裝與配置（二）-創(chuàng)新互聯(lián)

一、安裝擴展源

成都創(chuàng)新互聯(lián)成立于2013年，先為合水等服務建站，合水等地企業(yè)，進行企業(yè)商務咨詢服務。為合水企業(yè)網(wǎng)站制作PC+手機+微官網(wǎng)三網(wǎng)同步一站式服務解決您的所有建站問題。

[root@www ~]# rpm -ivh http://mirrors.yun-idc.com/epel/6/i386/epel-release-6-8.noarch.rpm

二、安裝Nagios相關軟件包

[root@www ~]# yum -y install httpd nagios nagios-plugins nagios-plugins-all nrpe nagios-plugins-nrpe

三、設置nagios后臺登錄用戶名和密碼

[root@www ~]# htpasswd -c /etc/nagios/passwd nagiosadmin  #這里指定用戶名為nagiosadmin，而不是其他
New password: 
Re-type new password: 
Adding password for user nagiosadmin

四、檢查Nagios配置

[root@www ~]# nagios -v /etc/nagios/nagios.cfg

五、啟動Nagios和http服務

[root@www ~]# /etc/init.d/httpd start
Starting httpd:                                            [  OK  ]
[root@www ~]# /etc/init.d/nagios start
Starting nagios: done.

六、瀏覽器訪問

【Nagios】Linux監(jiān)控軟件安裝與配置（二）

七、Nagios添加被監(jiān)控客戶端主機

1、安裝Nagios服務

[root@sh ~]# rpm -ivh epel-release-6-8.noarch.rpm
[root@sh ~]# yum -y install nagios-plugins nagios-plugins-all nrpe nagios-plugins-nrpe

2、修改/etc/nagios/nrpe.cfg文件

[root@sh ~]# vim /etc/nagios/nrpe.cfg

 81 allowed_hosts=127.0.0.1,192.168.1.21 #添加nagios服務端IP
 97 dont_blame_nrpe=1   #0改為1

3、啟動nrpe

[root@sh ~]# /etc/init.d/nrpe start
Starting nrpe:                                             [  OK  ]

4、Nagios服務端添加被監(jiān)控客戶端主機

[root@www ~]# cd /etc/nagios/conf.d/
[root@www conf.d]# ls
[root@www conf.d]# vim 192.168.1.251.cfg
define host{
        use                     linux-server
        host_name           192.168.1.251
        alias                       1.251
        address                 192.168.1.251
        }

define service{
        use                     generic-service
        host_name               192.168.1.251
        service_description     check_ping
        check_command           check_ping!100.0,20%!200.0,50%
        max_check_attempts 5
        normal_check_interval 1
}

define service{
        use                     generic-service
        host_name               192.168.1.251
        service_description     check_ssh
        check_command           check_ssh
        max_check_attempts      5  #當nagios檢測到問題時，一共嘗試檢測5次都有問題才會告警，如果該數(shù)值為1，那么檢測到問題立即告警
        normal_check_interval   1  #重新檢測的時間間隔，單位是分鐘，默認是3分鐘
        notification_interval   60 #在服務出現(xiàn)異常后，故障一直沒有解決，nagios再次對使用者發(fā)出通知的時間。如果你認為，所有的事件只需要一次通知就夠了，可以把這里的選項設為0
}

define service{
        use                     generic-service
        host_name               192.168.1.251
        service_description     check_http
        check_command           check_http
        max_check_attempts      5
        normal_check_interval 1
}

5、檢查配置

[root@www conf.d]# nagios -v /etc/nagios/nagios.cfg

6、重啟nagios

[root@www conf.d]# /etc/init.d/nagios restart
Running configuration check...done.
Stopping nagios: done.
Starting nagios: done.

7、查看效果

【Nagios】Linux監(jiān)控軟件安裝與配置（二）

八、添加nrpe支持的監(jiān)控服務

1、添加nrpe服務

[root@www ~]# vim /etc/nagios/objects/commands.cfg 
################################################################################


# 'notify-host-by-email' command definition
define command{
        command_name    notify-host-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HO
STNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail
-s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
        }

# 'notify-service-by-email' command definition
define command{
        command_name    notify-service-by-email

        }

define command{
        command_name    check_nrpe  #自定義check
        command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
        }


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

2、添加nrpe服務腳本

[root@www ~]# vim /etc/nagios/conf.d/192.168.1.251.cfg
......
#check_nrpe
define service{
        use     generic-service
        host_name       192.168.1.251
        service_description     check_load  #監(jiān)控負載
        check_command           check_nrpe!check_load
        max_check_attempts 5
        normal_check_interval 1
}
define service{
        use     generic-service
        host_name       192.168.1.251
        service_description     check_disk_sda1
        check_command           check_nrpe!check_hda1  #check_nrpe為前面自定義的模塊名稱，check_hda1為被監(jiān)控主機/etc/nagios/nrpe.cfg文件里定義的腳本名稱
        max_check_attempts 5
        normal_check_interval 1
}
#define service{    #可以添加多塊磁盤監(jiān)控
#        use     generic-service
#        host_name       192.168.1.251
#        service_description     check_disk_hda2
#        check_command           check_nrpe!check_hda2
#        max_check_attempts 5
#        normal_check_interval 1
#}

[root@www ~]# nagios -v /etc/nagios/nagios.cfg 
.......
Total Warnings: 0
Total Errors:   0
Things look okay - No serious problems were detected during the pre-flight check

3、被監(jiān)控主機通過nrpe.cfg文件定義的腳本命令

[root@sh ~]# vim /etc/nagios/nrpe.cfg
# The following examples use hardcoded command arguments...

command[check_users]=/usr/lib64/nagios/plugins/check_users -w 5 -c 10
command[check_load]=/usr/lib64/nagios/plugins/check_load -w 15,10,5 -c 30,25,20
command[check_hda1]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sda1
#command[check_hda2]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/hda2
command[check_zombie_procs]=/usr/lib64/nagios/plugins/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=/usr/lib64/nagios/plugins/check_procs -w 150 -c 200

4、重啟服務

[root@www ~]# /etc/init.d/nagios restart
Running configuration check...done.
Stopping nagios: done.
Starting nagios: done.

[root@sh ~]# /etc/init.d/nrpe restart
Shutting down nrpe:                                        [  OK  ]
Starting nrpe:                                             [  OK  ]

5、web頁面查看結(jié)果

【Nagios】Linux監(jiān)控軟件安裝與配置（二）

6、查看nagios日志文件

[root@www ~]# ls /var/log/nagios/
archives  nagios.log  objects.cache  retention.dat  spool  status.dat

[root@www ~]# cat /var/log/nagios/nagios.log

九、Nagios配置郵件警告

1、增加define contact和define contactgroup配置

[root@www ~]# vim /etc/nagios/objects/contacts.cfg 

# We only have one contact in this simple configuration file, so there is
# no need to create more than one contact group.

define contactgroup{
        contactgroup_name       admins
        alias                   Nagios Administrators
        members                 nagiosadmin
        }

# add mail addressee
define contact{
        contact_name               admin
        use                             generic-contact
        alias                           administrator
        email              741616710@qq.com
        }

define contact{
        contact_name               ming
        use                             generic-contact
        alias                            HM
        email              root@huangmingming.cn
        }

define contactgroup{
        contactgroup_name          common
        alias                            common
        members                          admin,ming
        }

2、修改define service，增加相應配置

[root@www ~]# vim /etc/nagios/conf.d/192.168.1.251.cfg

define service{

use generic-service

host_name 192.168.1.251

service_description check_http

check_command check_http

max_check_attempts 5

normal_check_interval 1

contact_groups common

notifications_enabled 1

notification_period 24x7

notification_options w,u,c,r

}

[root@www ~]# nagios -v /etc/nagios/nagios.cfg
