注：
本文档基于nagios+apache的模式，安装nagios时须预先编译安装apache，在此不进行apache编译安装的赘述。
一：配置apache
# vi /usr/local/apache/conf/extra/httpd-vhosts.conf
NameVirtualHost *:80
<VirtualHost *:80>
ServerName 192.168.189.132
DocumentRoot "/www"
<Directory "/www">
Order deny,allow
Deny from all
</Directory>
#以下是apache上，nagios所需的配置信息：
Scriptalias/nagios/cgi-bin /usr/local/nagios/sbin
<directory"/usr/local/nagios/sbin">
Authtype basic
Options execcgi
Allowoverride none
Order allow,deny
Allow from all
Authname "nagios access"
Authuserfile /usr/local/nagios/etc/htpasswd
Require valid-user
</directory>
Alias /nagios /usr/local/nagios/share
<directory"/usr/local/nagios/share">
Authtype basic
Options none
Allowoverride none
Order allow,deny
Allow from all
Authname "nagios access"
//配置nagios用户验证
Authuserfile /usr/local/nagios/etc/htpasswd
Require valid-user
</directory>
</VirtualHost>
二：创建nagios用户与组
# useradd nagios
# groupadd nagios
# usermod –a –Gnagios nobody
# usermod –a –Gnagios nagios
二：下载nagios相关软件包，并编译安装及环境配置
# cd /usr/local/src
# wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.4.1.tar.gz
# wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.16.tar.gz
# wget http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.13.tar.gz
# tar -zxvf nagios-3.4.1.tar.gz
# tar -zxvf nagios-plugins-1.4.16.tar.gz
# tar -zxvf nagios/nrpe-2.13.tar.gz
编译安装nagios
# cd nagios-3.4.1/
# ./configure --prefix=/usr/local/nagios --with-command-group=nagios
# make all
# make install
# make install-init
# make install-commandmode
# make install-config
编译安装nagios插件
# cd ../nagios-plugins-1.4.16
# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios
# make && make install
编译安装nrpe
# cd ../nrpe-2.13
# ./configure --prefix=/usr/local/nagios
# make all
# make install-plugin
设置nagios目录权限
# chown –R nagios:nagios /usr/local/nagios/
配置用户密码访问
# /usr/local/apache/bin/htpasswd -cm /usr/local/nagios/etc/htpasswd nagiosadmin
New password:
Re-type new password:
Adding password for usernagiosadmin
三：启用nagios，并访问测试
开启apache服务
# /usr/local/apache/bin/apachectl -k start
检测nagios配置文件语法是否正确
# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
若语法正确，则可以正常启动nagios
# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg -d
(也可使用系统服务方式启动：service nagios start)
页面访问测试
出现以上页面，说明nagios安装部署成功。后续需在服务中添加主机与服务，方能开始进行监控。
