一、库文件安装
如果系统中没有这些软件可以使用yum方式安装
#yum –y install gcc glibc glibc-common gd gd-devel
另外，新版的Nagios需要PHP程序的支持，所以在安装Nagios之前最好先安装Apache+PHP


二、创建用户维护Nagios的用户和组
#/usr/sbin/useradd nagios
#passwd nagios
#/usr/sbin/groupadd nagcmd
#/usr/sbin/usermod -a -G nagcmd nagios


三、安装Nagios和插件
安装Nagios
#tar zxvf nagios-3.2.1.tar.gz
#cd nagios-3.2.1
#./configure --prefix=/usr/local/nagios --with-command-group=nagcmd
#make all
#make install
#make install-init
#make install-config
#make install-commandmode

安装Nagios-plugins
#tar zxvf nagios-plugins-1.4.14.tar.gz
#cd nagios-plugins-1.4.14
#./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios
#make && make install

检查配置文件是否正确
#/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
clip_image001

启动Nagios
#service nagios start


四、配置web接口（对Nagios做授权访问）
创建认证用户
#/usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/nagiospwd nagiosadmin

修改apache配置文件，将如下内容加入配置文件底部
#vi /usr/local/apache/conf/httpd.conf
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/nagiospwd
    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"
    Authuserfile /usr/local/nagios/etc/nagiospwd
    Require valid-user
</directory>


五、测试
     配置完毕后重新启动Apache，然后在浏览器中访问http://localhost/nagios 正常的话应该会弹出一个登录窗口，填写完用户名和密码后就可以看到Nagios的WEB界面了
