系统是freebsd
安装过程：
一、 所需软件
nagios-2.0rc2.tar
nagios-plugins-1.4.tar
imagepak-base.tar.gz
二、 安装
1、nagios安装
tar –xvzf nagios-2.0rc2.tar
mkdir /usr/local/nagios
pw useradd nagios –d /usr/local/nagios
pw addgroup root
chmod 755 /usr/local/nagios
cd nagios-2.0rc2
./configure --prefix=/usr/local/nagios --with-gd-lib=/usr/local/lib --with-gd-inc=/usr/local/include
make all
make install
make install-init ##This installs the init script in /usr/local/etc/rc.d
make install-commandmode
make install-config ##将初始的配置文件安装到/usr/local/nagios/etc
注:在makeinstall-init这一步的时候可能会进行不下去，这时只要加个root组即可。
pw addgroup root
2、nagios-plugins的安装
tar –xvzf nagios-plugins-1.4.tar
mkdir /usr/local/nagios-plugins
cd nagios-plugins-1.4
./configure --prefix=/usr/local/nagios-plugins
make all
make install
安装完成以后在/usr/local/nagios-plugins会产生一个libexec的目录，将该目录全部移动到/usr/local/nagios目录下
mv /usr/local/nagios-plugins/libexec /usr/local/nagios
3、imagepak-base的安装
tar –xvzf imagepak-base.tar.gz
解压以后是base目录
cp –R base /usr/local/nagios/share/images/logos
4、安装过程全部结束
这个配置没问题
一、配置apache
在apache的配置文件httpd.conf中追加
ScriptAlias /nagios/cgi-bin/ /usr/local/nagios/sbin/
<Directory "/usr/local/nagios/sbin/">
AllowOverride AuthConfig
Options ExecCGI
Order allow,deny
Allow from all
</Directory>
Alias /nagios/ /usr/local/nagios/share/
<Directory "/usr/local/nagios/share">
Options None
AllowOverride AuthConfig
Order allow,deny
Allow from all
</Directory>
二、设置访问权限
1、在/usr/local/nagios/share目录下
vi .htaccess
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/.htpasswd
require valid-user
2、在/usr/local/nagios/sbin目录下
vi .htpasswd
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/.htpasswd
require valid-user
3、/usr/local/apache/bin/htpasswd –c /usr/local/nagios/etc/.htpasswd nagios
这个apache目录根据安装目录的不同而不同,主要所以用.htpasswd这个命令生成用户名和密码
三、配置nagios
1、在/usr/local/nagios/etc下是nagios的配置模板文件.cfg-sample,把.cfg-sample文件全部拷贝成.cfg
例如:cp nagios.cfg-sample nagios.cfg
全部拷贝完成即可.
2、vi dependencies.cfg (在2.0没有生成这个文件，自己创建)
然后保存即可.(在1.2用一个空的文件代替原来的dependencies.cfg文件,否则会出错)
3、修改minimal.cfg，把里面所有定义command的全部注释掉
vi /etc/minimal.cfg
修改cgi.cfg
修改use_authentication=1为use_authentication=0,即不用验证.不然有一些页面不会显示。
4、然后检查配置文件是否出错
/usr/local/nagios/bin/nagios –v /usr/local/nagios/etc/nagios.cfg
出现Total Warnings: 0
Total Errors: 0
为正常
出错的话,就是.cfg文件有问题
5、启动后台进程
/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
/usr/local/etc/rc.d/nagios start
6、http://10.4.8.81/nagios/index.html
(如果有些页面看不到的话.可以在cgi.cfg文件中
把带有authorized的选项前的#号去掉即可)
这些配置完以后，基本的nagios配置完成。
nagios能正常起动
关键问题：有错误，请帮指正
hosts.cfg 配置

contact_groups linux-admins
notification_interval 240
notification_period 24x7
notification_options c,r
check_command check_ping!100.0,20%!500.0,60%
}
nagios.cfg 配置
cfg_file=/usr/local/nagios/etc/hostgroups.cfg
cfg_file=/usr/local/nagios/etc/hosts.cfg
cfg_file=/usr/local/nagios/etc/services.cfg
cfg_file=/usr/local/nagios/etc/contactgroups.cfg
cfg_file=/usr/local/nagios/etc/contacts.cfg
主配置中以前是没有起用的，现在启用了，就改了这些
问题：重点啊，帮帮啊
