一、先安裝apahce+php這里不做介紹了。

二、安裝nagios
1、建立用戶

#?useradd?-s?/sbin/nologins?nagios?

#?mkdir?/usr/local/nagios?

#?chown?-R??nagios.nagios?/usr/local/nagios/?

?

#?tar?xf?nagios-3.4.1.tar.gz?

#?cd?nagios?

#?./configure?--prefix=/usr/local/nagios/?

#?make?all?

#?make?install?

#?make?install-init?

#?make?install-commandmode?

#?make?install-config?

?

#?chkconfig?--add?nagios?

#?chkconfig?nagios?on?

#?chkconfig?--list?nagios?

2、安裝插件

#?tar?xf?nagios-plugins-1.4.16.tar.gz?

#?cd?nagios-plugins-1.4.16?

#?./configure?--prefix=/usr/local/nagios/?

#?make?&&?make?install?

三、修改配置
1、修改apache的配置文件

#?vim?/usr/local/apache2/conf/httpd.conf?

User?nagios?

Group?nagios?

?

最后添加如下內容，設置成需要輸入密碼才能登陸?

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?"Nagions?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"?

????????AuthUserFile?/usr/local/nagios/etc/htpasswd?

????????Require?valid-user?

</Directory>?

?

建立登陸的用戶名密碼?

#?/usr/local/apache2/bin/htpasswd?-c?/usr/local/nagios/etc/htpasswd?admin?

啟動httpd以后訪問輸入用戶名密碼就可以看到Nagios了?

2、配置nagios

在/usr/local/nagios/etc下建立2個文件：?

（1）hosts.cfg定義主機的文件?

define?host{?

????use????linux-server????????//引用linux-server的屬性信息，linux-server在templates.cfg中定義?

????host_name????localhost????//主機名?

????alias????host1????????????//別名?

????address????192.168.163.143????????//ip地址?

}?

define?host{?

????use????linux-server?

????host_name????host-142?

????alias????host2?

????address????192.168.163.142?

}?

?

（2）services.cfg?定義主機服務的文件?

define?service{?

????use????local-service????????//引用local-service的屬性信息，在template.cfg中定義?

????host_name????host-142????//監控那個主機，host-142在hosts.cfg中定義?

????service_description????ssh????//對監控內容的描述?

????check_command????check_ping????//指定監控的命令，check_ping在commands.cfg中定義?

}?

define?service{?

????use????local-service?

????host_name????localhost?

????service_description????Ping?

????check_command????check_ping?

}?

3、添加admin用戶信息，這里的admin用戶是之前htpasswd生成的用戶：

default_user_name=admin?

authorized_for_system_information=nagiosadmin,admin?

authorized_for_configuration_information=nagiosadmin,admin?

authorized_for_system_commands=nagiosadmin,admin?

authorized_for_all_services=nagiosadmin,admin?

authorized_for_all_hosts=nagiosadmin,admin?

authorized_for_all_service_commands=nagiosadmin,admin?

authorized_for_all_host_commands=nagiosadmin,admin?

4、修改nagios.cfg文件，添加文件路徑信息：

cfg_file=/usr/local/nagios/etc/hosts.cfg?

cfg_file=/usr/local/nagios/etc/services.cfg?

cfg_file=/usr/local/nagios/etc/objects/commands.cfg?

cfg_file=/usr/local/nagios/etc/objects/contacts.cfg?

cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg?

cfg_file=/usr/local/nagios/etc/objects/templates.cfg

5、檢查是否有問題
# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
如下正常，如果有問題的話nagios會提示那有錯誤非常明確的

#service nagios restart
啟動nagios后訪問下:

1、查看主機的信息：

2、查看服務的信息
