nagios監控服務器 10.1.7.110
linux客戶端服 10.1.7.120
windows客戶端 10.1.7.119
1創建nagios組和賬號
root@nagios ~]# useradd -m nagios
[root@nagios ~]# groupadd nagcmd
[root@nagios ~]# groupadd nagcmd
[root@nagios ~]# usermod -a -G nagcmd nagios
[root@nagios ~]# usermod -a -G nagcmd apache
2編譯安裝
[root@nagios ~]# tar xvf nagios-3.2.0.tar.gz
[root@nagios ~]# cd nagios-3.2.0
[root@nagios nagios-3.2.0]# less Makefile
[root@nagios nagios-3.2.0]# ./configure --with-command-group=nagcmd\ --with-nagios-user=nagios\ --with-nagios-group=nagios
[root@nagios nagios-3.2.0]# make all
[root@nagios nagios-3.2.0]# make install

[root@nagios nagios-3.2.0]# make install-config
[root@nagios nagios-3.2.0]# make install-commandmode
[root@nagios nagios-3.2.0]# make install-webconf
3爲nagios設置web驗證密碼
root@nagios nagios-3.2.0]# htpasswd -c usr/local/nagios/etc/htpasswd.users nagiosadmin
5設置nagios的開機啓動
root@nagios ~]# chkconfig --add nagios
[root@nagios ~]# chkconfig nagios on
6修改selinux
[root@nagios nagios-3.2.0]# cat /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= disable:
二 安裝nagios的插件 nagios-plugin
[root@nagios ~]# tar xvf nagios-plugins-1.4.14.tar.gz
[root@nagios ~]# cd nagios-plugins-1.4.14
[root@nagios nagios-plugins-1.4.14]# ./configure --prefix=/usr/local/nagios/ --with-nagios-user=nagios --with-nagios-group=nagios
[root@nagios nagios-plugins-1.4.14]# make && make install
檢查主機是佛存在
[root@nagios ~]# cd /usr/local/nagios/etc/
[root@nagios etc]# ls -l

# Definitions for monitoring the local (Linux) host
#cfg_file=/usr/local/nagios/etc/objects/localhost.cfg //註釋掉此行
3主機定義文件配置

}
~
4服務定義文件配置
[root@nagios etc]# vim objects/services.cfg

service_description check-host-alive
check_period 24x7
max_check_attempts 4
normal_check_interval 3
retry_check_interval 2
contact_groups sagroup
notification_interval 10
notification_period 24x7

check_command check-host-alive
}
5聯繫人定義文件配置
[root@nagios etc]# vim objects/contacts.cfg
define contact{
contact_name nagiosadmin ; Short name of user
use generic-contact ; Inherit default values from generic-contact template (defined above)
alias Nagios Admin ; Full name of user

define contactgroup {
contactgroup_name sagroup
alias system administrator group
members nagiosadmin
}
7修改目錄所有者
~
[root@nagios etc]# chown -R nagios.nagios objects/
8檢查配置文件是否正卻
[root@nagios etc]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
Total Warnings: 0
Total Errors: 0
9啓動nagios服務
[root@nagios etc]# etc/init.d/httpd restart
[root@nagios etc]# /etc/init.d/nagios start
10 測試功能
http://10.1.7.110/nagios/ 輸入 nagiosadmin 密碼 accp
三 使用nagios監控linux客戶端
1 nagios監控服務器的配置
[root@nagios ~]# tar zxvf nrpe-2.12.tar.gz
[root@nagios ~]# cd nrpe-2.12
[root@nagios nrpe-2.12]# ./configure && make all
[root@nagios nrpe-2.12]# make install-plugin
[root@nagios nrpe-2.12]# make install-daemon
[root@nagios nrpe-2.12]# make install-daemon-config
[root@nagios nrpe-2.12]# make install-xinetd
2 配置
[root@nagios nrpe-2.12]# vim /etc/xinetd.d/nrpe
server = /usr/local/nagios/bin/nrpe
server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
log_on_failure += USERID
disable = no
only_from = 127.0.0.1,10.1.7.120,10.1.7.119
3 添加端口
[root@nagios nrpe-2.12]# vim /etc/services
nrpe 5666/tcp #nrpe
4 重新啓動 xinetd服務
[root@nagios nrpe-2.12]# /etc/init.d/xinetd restart
[root@nagios nrpe-2.12]# netstat -na | grep 5666
以上步驟要到客戶機上做 1--4
5修改配置文件commands.cfg加入對nrpe的支持
[root@nagios ~]# vim /usr/local/nagios/etc/objects/commands.cfg
#nrpe set
define command {
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H $ HOSTADDRESS$ -c $ ARG1$
}
檢查nrpe命令那些可用
[root@nagios ~]# cat /usr/local/nagios/etc/nrpe.cfg
command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda1
command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200
7 使用命令監控客戶端
[root@nagios ~]# vim /usr/local/nagios/etc/objects/services.cfg
define service{
host_name Nagios-server
service_description check-users
check_period 24x7
max_check_attempts 4
normal_check_interval 3
retry_check_interval 2
contact_groups sagroup
notification_interval 10
notification_period 24x7
notification_options w,c,u,r
check_command check-nrpe!check_users
}
define service{
host_name Nagios-server
service_description check-load
check_period 24x7
max_check_attempts 4
normal_check_interval 3
retry_check_interval 2
contact_groups sagroup
notification_interval 10
notification_period 24x7
notification_options w,c,u,r
check_command check-nrpe!check_load
}
define service{
host_name Nagios-server
service_description check-total-procs
check_period 24x7
max_check_attempts 4
normal_check_interval 3
retry_check_interval 2
contact_groups sagroup
notification_interval 10
notification_period 24x7
notification_options w,c,u,r
check_command check-total_procs
}
