软件下载地址：http://yunpan.cn/QbFvRDxugZZsT
这里有配置nagios所需的所有的各种版本的软件资源，包括fetion资源

1.实验环境：nagios主机：desk32.example.com 192.168.122.32\mysql主机：desk3.example.com 192.168.122.32.nagios的安装：nagios是用一些命令在被监控主机上运行后将采集的信息返回。编译需要的依赖包：

yum install httpd gcc make gd-devel perl-ExtUtils-Embed.x86_64 -y
yum  -y   localinstall  gd-devel-2.0.35-10.el6.x86_64
useradd nagios          #运行 nagios 服务的用户
usermod -G nagios apache        #使 apache 用户对 nagios 目录具有写权限,不然 web 页面操作失败
tar jxf nagios-cn-3.2.3.tar.bz2
cd nagios-cn-3.2.3
useradd  nagios
usermod -G nagios apache
./configure --prefix=/usr/local/nagios --enable-embedded-perl
make all
make install
make install-init
make install-commandmode
make install-config
make install-webconf

bin Nagios 执行程序所在目录,这个目录只有一个文件 nagiosetc Nagios 配置文件位置,初始安装完后,只有几个*.cfg-sample 文件sbin Nagios Cgi 文件所在目录,也就是执行外部命令所需文件所在的目录share Nagios 网页文件所在的目录var Nagios 日志文件、spid 等文件所在的目录

3.安装nagios-plugin插件：安装依赖包：

yum -y install mysql-devel openssl-devel
[root@desk32 nagios-plugins-1.4.16]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios --enable-extra-opts  --enable-perl-modules
[root@desk32 nagios-plugins-1.4.16]#make && make install

再没有安装插件前在/usr/local/nagios/libexec下没有东西，安装后次目录下安装的是nagios用于检查的命令。

[root@desk32 nagios-plugins-1.4.16]# cd /usr/local/nagios/
[root@desk32 nagios]# ls
bin  etc  include  libexec  perl  sbin  share  var
[root@desk32 nagios]# ls libexec/
…........check_apt check_file_age check_jabber check_nt        check_rpc       check_time   check_breeze    check_flexlm        check_load         check_ntp  …...........

主配置文件 nagios.cfg 定义和控制 nagios 行为需要修改Cgi 配置文件 cgi.cfg 浏览器执行诸如重启 nagios 服务等要修改宏定义文件 Resource.cfg 定义插件路径不需修改命令定义文件 Commands.cfg 定义怎么发送短信、邮件等需要修改其他文件 contactgroups.cfg,contacts.cfg 监控对象配置文件,如主机主配置文件，包含,手动联系人配置文件

[root@desk32 etc]# vim nagios.cfg
#注释或删掉这行
#cfg_file=/usr/local/nagios/etc/localhost.cfg
#主机配置文件路径
cfg_file=/usr/local/nagios/etc/objects/hosts.cfg
cfg_file=/usr/local/nagios/etc/objects/service.cfg
//将服务与主机分开
#//主机组配置文件路径
cfg_file=/usr/local/nagios/etc/hostgroups.cfg
#联系人配置文件路径
cfg_file=/usr/local/nagios/etc/contacts.cfg
#联系组配置文件路径
cfg_file=/usr/local/nagios/etc/contactgroups.cfg
#服务配置文件路径
cfg_file=/usr/local/nagios/etc/services.cfg
#监视时段配置文件路径
cfg_file=/usr/local/nagios/etc/timeperiods.cfg
#在 web 界面下重启 nagios、停止主机/服务检查等操作,.默认值是 0.
check_external_commands=1
#根据自己的情况定这个命令检查时间间隔.默认值是 1 秒.
command_check_interval=10s

注意：以上的有些文件的位置是不正确的。因为存在软件的升级等原因，文件位置有一些的调整

[root@desk32 objects]# cp localhost.cfg hosts.cfg #创建主机定义文件
[root@desk32 objects]# cp localhost.cfg service.cfg   #创建服务定义文件
[root@desk32 objects]#vim hosts.cfg  #只剩下对于主机及主机组的定义将服务的定义删掉

以下就是主机组的区别：

以下关于服务的定义：

[root@desk32 objects]# vim /usr/local/nagios/etc/objects/service.cfg
#########################################

ot@desk32 objects]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
Total Warnings: 0
Total Errors:   0
#保证配置文件的语法没有问题
[root@desk32 etc]# /etc/init.d/nagios start

4.apache的安装配置：

yum -y install httpd
配置apache的虚拟主机：
[root@desk32 conf]# vim /etc/httpd/conf/httpd.conf
NameVirtualHost *:80
<VirtualHost *:80>
DocumentRoot /usr/local/nagios/share
ServerName nagios.example.com
</VirtualHost>
[root@desk32 conf]# /etc/init.d/httpd restart
[root@desk32 conf]# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
#nagios 监控页面访问用户和密码

以上的管理员的用户信息实在：/usr/local/nagios/etc/cgi.cfg中定义的，当然是可以修改的；『#如有多个用户,中间用逗号隔开authorized_for_system_information=seryauthorized_for_configuration_information=seryauthorized_for_system_commands=seryauthorized_for_all_services=seryauthorized_for_all_hosts=nagiosadmin,seryauthorized_for_all_service_commands=seryauthorized_for_all_host_commands=sery在这里指定的用户”sery”可以通过浏览器操纵 nagios 服务的关闭、重启等各种操作』完成以上的所有操作后我们在装有浏览器的主机上添加虚拟主机中的域名解析：192.168.122.32nagios.example.com网页访问：http://nagios.example.com

2）ngios监控其他的主机（1）监控mysql主机的mysql服务：mysql 主机上运行有 mysql 服务,在其上创建监控检测帐户

mysql> create database nagdb;
mysql> grant select on nagdb.* to nagdb@'192.168.122.32';
mysql> flush privileges;
[root@desk32 libexec]# cd /usr/local/nagios/libexec/
[root@desk32 libexec]# ./check_mysql -H 192.168.122.3 -u nagdb -d nagdb
Uptime: 363  Threads: 1  Questions: 6  Slow queries: 0  Opens: 15  Flush tables: 1  Open tables: 8  Queries per second avg: 0.16
## -H 指定检测的主机，-u 制定select mysql的用户，-d  指定登录select的数据库

添加监控主机信息：

vim /usr/local/nagios/etc/objects/hosts.cfg   添加：
define host{
use                     linux-server
host_name              desk3.example.com
alias                   mysql服务器
address                 192.168.122.3 ;desk3.example.com
icon_image              server.gif
statusmap_image         server.gd2
2d_coords               500,200
3d_coords               500,200,100
}
[root@desk32 objects]# vim /usr/local/nagios/etc/objects/service.cfg
添加：
###################check_mysql#############################
define service{
use                     local-service
host_name               desk3.example.com
service_groups          mysql服务组
service_description     mysql服务
check_command           check_mysql
}
##########################check_mysql_groups#########################
define servicegroup{
servicegroup_name       mysql服务组
alias                   mysql服务器
members desk3.example.com,mysql服务
}
对于位置在libexec下的命令还必须在commands.cfg中定义才可以使用；
#####################check_mysql###########################
define command{
command_name    check_mysql
command_line    $USER1$/check_mysql -H $HOSTADDRESS$ -u nagdb -d nagdb
}
#$USER1$ 这的就是libexec目录
[root@desk32objects]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
[root@desk32 objects]# /etc/init.d/nagios reload

刷新网页后发现主机数多了一个：在该主机下的服务：

以上的mysql服务之所以可以直接就可以监控远程的主机，是因为chek_mysql的命令本身就带有-H指定主机访问主机的能力；其他的监控命令并没有这样的功能，所以监控远程的其他的服务必须借助nrpe插件：

The NRPE addon consists of two pieces:–The check_nrpe plugin, which resides on the local monitoring machine–The NRPE daemon, which runs on the remote Linux/Unix machineWhen Nagios needs to monitor a resource of service from a remote Linux/Unix machine:–Nagios will execute the check_nrpe plugin and tell it what service needs to be checked–The check_nrpe plugin contacts the NRPE daemon on the remote host over an (optionally) SSL-protected connection–The NRPE daemon runs the appropriate Nagios plugin to check the service or resource–The results from the service check are passed from the NRPE daemon back to the check_nrpe plugin, which then returns the check results to the Nagios process.Note: The NRPE daemon requires that Nagios plugins be installed on the remote Linux/Unix host. Without these,the daemon wouldn't be able to monitor anything.

在nagios主机上使用check_nrpe通过ssl链接远程的主机的nrpe使用远程主机上的命令检查主机信息然后又将检查的信息返回；所以在远程主机上要按装nrpe及nagios-plugins
在远程主机desk3上:

tar zxf nagios-plugins-1.4.16.tar.gz
cd nagios-plugins-1.4.16
./configure --with-nagios-user=nagios --with-nagios-group=nagios --enable-extra-opts --enable-perl-modules  --enable-libtap –with-openssl
make && make install
[root@desk3 nrpe-2.14]# cd /usr/local/nagios/
[root@desk3 nagios]# chown  nagios.nagios . -R
[root@desk3 nrpe-2.14]# yum -y install xinetd #用于管理nrpe的启动端口信息
tar zxf nrpe-2.14.tar.gz
cd nrpe-2.14
[root@desk3 nrpe-2.14]./configure
[root@desk3 nrpe-2.14]# make all
[root@desk3 nrpe-2.14]# make install
[root@desk3 nrpe-2.14]# make install-daemon-config
[root@desk3 nrpe-2.14]# make install-xinetd
[root@desk3 nagios]# vim /etc/xinetd.d/nrpe
only_from       = 192.168.122.32
[root@desk3 nagios]# vim /etc/services
nrpe            5666/tcp #TCP port service nrpe
[root@desk3 etc]# vim /usr/local/nagios/etc/nrpe.cfg
command[check_disk]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /
因为系统上的分区可能会是lvm所以这样修改
[root@desk3 etc]# /etc/init.d/xinetd restart
[root@desk3 etc]# netstat -anplt
tcp        0      0 :::5666                     :::*                LISTEN      3984/xinetd
因为在nagios主机上是通命令check_nrpe实现的所以在ngios主机上同样安装nrpe
[root@desk32 libexec]# ./check_nrpe -H 192.168.122.3
NRPE v2.14
#看见如此信息则表明nrpe征程链接

Configuring Things On The Nagios Host
command definition for the check_nrpe plugin would look like this:

[root@desk32 libexec]# vim /usr/local/nagios/etc/objects/commands.cfg
###################chek_nrpe##############################

}
##########################check_nrpe+mysql_groups#####################

}
为了方便查看将host.cfg中的主机的定义中的desk3.example.com的alias改为了“远程主机”
[root@desk32 libexec]# /usr/local/nagios/bin/nagios -v               \
/usr/local/nagios/etc/nagios.cfg
[root@desk32 libexec]# /etc/init.d/nagios reload

可以看见远程的主机desk3的nrpe的那几个服务已经添加进来了；
测试：mysql测试：远程mysql主机上：

[root@desk3 etc]# /etc/init.d/mysqld stop

[root@desk3 etc]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vol0-root

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vol0-root
.9G  3.6G   66M  99% /

naios采集到的所有的图形信息，均存储与rrdtool的环形数据库中，其数据在/usr/local/nagios/var/rrd下存储的；
5.图形日志显示：

后“图书”标志为图形日志，当前无法显示：

[root@desk32 ~]# yum localinstall rrdtool-perl-1.3.8-6.el6.x86_64.rpm
[root@desk32 logs]# yum -y install perl-CGI

刷新后即可出现图形化的日志信息

7）nagios与fetion的整合
