时间:2023-01-01 08:11:34 点击:139

OS:FreeBSD 7.0

到http://www.nagios.org/download/下载所需的软件包

1.nagios-3.1.2.tar.gz

2.nagios-plugins-1.4.13.tar.gz

系统需求:

1. Apache

2. GCC编译器

3. GD库与开发库

以上软件安装好后,开始安装nagios。

1.解压缩

#tar zxvf nagios-2.5.tar.gz

2.建立运行nagios的用户:

#pw adduser nagios

#passwd nagios

3.创建一个用户组名为nagcmd用于从Web接口执行外部命令。将nagios用户和apache用户都加到这个组中。必须确定web服务器以哪个用户运行的,通常为:apache。我的服务器配置是www。

#grep “^User“ /usr/local/apache2/conf/httpd.conf

#pw groupadd nagcmd

#pw usermod www -G nagcmd

#pw usermod nagios -G nagcmd

运行Nagios配置脚本并使用先前开设的用户及用户组

# ./configure –prefix=/usr/local/nagios –with-gd-lib=/usr/local/lib –with-gd-inc=/usr/local/include –with-command-group=nagcmd

*** Configuration summary for nagios 3.1.2 06-23-2009 ***:

General Options:

————————-

Nagios executable: nagios

Nagios user/group: nagios,nagios

Command user/group: nagios,nagios

Embedded Perl: no

Event Broker: yes

Install ${prefix}: /usr/local/nagios

Lock file: ${prefix}/var/nagios.lock

Check result directory: ${prefix}/var/spool/checkresults

Init directory: /usr/local/etc/rc.d

Apache conf.d directory: /etc/httpd/conf.d

Mail program: /usr/bin/mail

Host OS: freebsd7.0

Web Interface Options:

————————

HTML URL: http://localhost/nagios/

CGI URL: http://localhost/nagios/cgi-bin/

Traceroute (used by WAP): /usr/sbin/traceroute

Review the options above for accuracy. If they look okay,

type ‘make all’ to compile the main program and CGIs.

编译Nagios程序包源码

#make all

安装二进制运行程序、初始化脚本、配置文件样本并设置运行目录权限

#make install

运行make install-init前请检查/usr/loca/etc/rc.d的目录权限。我的服务器是root:wheel.而Makefile中试root:root.

修改Makefile

INIT_DIR=/usr/local/etc/rc.d

INIT_OPTS=-o root -g root

改为:

INIT_DIR=/usr/local/etc/rc.d

INIT_OPTS=-o root -g wheel

然后运行make install-init。

#make install-init

#make install-commandmode

#make install-config

配置WEB接口

安装Nagios的WEB配置文件到Apache的conf目录下。Makefile文件中http的路径是/etc/httpd/conf.d。修改为自己apache的conf路径。

#make install-webconf

到此nagios核心程序安装完成!

客户化配置

样例配置文件默认安装在这个目录下/usr/local/nagios/etc,这些样例文件可以配置Nagios使之正常运行,只需要做一个简单的修改…

用你擅长的编辑器软件来编辑这个/usr/local/nagios/etc/objects/contacts.cfg配置文件,更改email地址nagiosadmin的联系人定义信息中的EMail信息为你的EMail信息以接收报警内容。

#vi /usr/local/nagios/etc/objects/contacts.cfg

配置WEB接口

配置apache的BASIC认证,创建一个nagiosadmin的用户用于Nagios的WEB接口登录。记下你所设置的登录口令,一会儿你会用到它。

#htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

然后修改apache的配置文件

#vi /usr/local/apache/conf/httpd.conf

添加如下内容:

ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin

Options ExecCGI

AllowOverride None

Order allow,deny

Allow from all

AuthName “Nagios access“

AuthType Basic

AuthUserFile /usr/local/nagios/etc/htpasswd.users

Require valid-user

Alias /nagios /usr/local/nagios/share

Options None

AllowOverride None

Order allow,deny

Allow from all

AuthName “Nagios Access“

AuthType Basic

AuthUserFile /usr/local/nagios/etc/htpasswd.users

Require valid-user

修改完毕,保存文件,并重启apache:

#/usr/local/apahce/bin/apachectl restart

重启Apache服务以使设置生效。

编译并安装Nagios插件

展开Nagios插件的源程序包

#tar xzf nagios-plugins-1.4.13.tar.gz

#cd nagios-plugins-1.4.11

#./configure –with-nagios-user=nagios –with-nagios-group=nagios –prefix=/usr/local/nagios-plugins

#make

#make install

安装完成以后在/usr/local/nagios-plugins-plugins会产生一个libexec的目录,将该目录全部移动到/usr/local/nagios目录下即可。

#mv /usr/local/nagios-plugins-plugins/libexec/ /usr/local/nagios/

启动Nagios

验证Nagios的样例配置文件

#/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

出现:

Total Warnings: 0

Total Errors: 0

Things look okay – No serious problems were detected during the pre-flight check

配置文件没有问题。

启动nagios

#/usr/lcoal/etc/rc.d/nagios start

登录WEB接口

你现在可以从WEB方式来接入Nagios的WEB接口了,你需要在提示下输入你的用户名(nagiosadmin)和口令,你刚刚设置的,这里用系统默认安装的浏览器,用下面这个超链接

http://localhost/nagios/如图:
