OS:FreeBSD 7.0

到http://www.nagios.org/download/下載所需的軟件包

1.nagios-3.1.2.tar.gz

2.nagios-plugins-1.4.13.tar.gz

系統(tǒng)需求：

1. Apache

2. GCC編譯器

3. GD庫(kù)與開(kāi)發(fā)庫(kù)

以上軟件安裝好后，開(kāi)始安裝nagios。

1.解壓縮

#tar zxvf nagios-2.5.tar.gz

2.建立運(yùn)行nagios的用戶：

#pw adduser nagios

#passwd nagios

3.創(chuàng)建一個(gè)用戶組名為nagcmd用于從Web接口執(zhí)行外部命令。將nagios用戶和apache用戶都加到這個(gè)組中。必須確定web服務(wù)器以哪個(gè)用戶運(yùn)行的，通常為：apache。我的服務(wù)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

運(yùn)行Nagios配置腳本并使用先前開(kāi)設(shè)的用戶及用戶組

# ./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.

編譯Nagios程序包源碼

#make all

安裝二進(jìn)制運(yùn)行程序、初始化腳本、配置文件樣本并設(shè)置運(yùn)行目錄權(quán)限

#make install

運(yùn)行make install-init前請(qǐng)檢查/usr/loca/etc/rc.d的目錄權(quán)限。我的服務(wù)器是root:wheel.而Makefile中試root:root.

修改Makefile

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

INIT_OPTS=-o root -g root

改為：

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

INIT_OPTS=-o root -g wheel

然后運(yùn)行make install-init。

#make install-init

#make install-commandmode

#make install-config

配置WEB接口

安裝Nagios的WEB配置文件到Apache的conf目錄下。Makefile文件中http的路徑是/etc/httpd/conf.d。修改為自己apache的conf路徑。

#make install-webconf

到此nagios核心程序安裝完成！

客戶化配置

樣例配置文件默認(rèn)安裝在這個(gè)目錄下/usr/local/nagios/etc，這些樣例文件可以配置Nagios使之正常運(yùn)行，只需要做一個(gè)簡(jiǎn)單的修改…

用你擅長(zhǎng)的編輯器軟件來(lái)編輯這個(gè)/usr/local/nagios/etc/objects/contacts.cfg配置文件，更改email地址nagiosadmin的聯(lián)系人定義信息中的EMail信息為你的EMail信息以接收?qǐng)?bào)警內(nèi)容。

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

配置WEB接口

配置apache的BASIC認(rèn)證，創(chuàng)建一個(gè)nagiosadmin的用戶用于Nagios的WEB接口登錄。記下你所設(shè)置的登錄口令，一會(huì)兒你會(huì)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

添加如下內(nèi)容：

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

<Directory “/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

</Directory>

Alias /nagios /usr/local/nagios/share

<Directory “/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

</Directory>

修改完畢，保存文件，并重啟apache：

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

重啟Apache服務(wù)以使設(shè)置生效。

編譯并安裝Nagios插件

展開(kāi)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

安裝完成以后在/usr/local/nagios-plugins-plugins會(huì)產(chǎn)生一個(gè)libexec的目錄，將該目錄全部移動(dòng)到/usr/local/nagios目錄下即可。

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

啟動(dòng)Nagios

驗(yàn)證Nagios的樣例配置文件

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

出現(xiàn)：

Total Warnings: 0

Total Errors: 0

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

配置文件沒(méi)有問(wèn)題。

啟動(dòng)nagios

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

登錄WEB接口

你現(xiàn)在可以從WEB方式來(lái)接入Nagios的WEB接口了，你需要在提示下輸入你的用戶名(nagiosadmin)和口令，你剛剛設(shè)置的，這里用系統(tǒng)默認(rèn)安裝的瀏覽器，用下面這個(gè)超鏈接

http://localhost/nagios/如圖：
