系統環境：Centos6.3?最小化安裝

環境準備

yum?install?–y?libxml2-devel?make?gcc

1、安裝前準備?

（1）創建nagios用戶和用戶組?

[root@localhost?~]#useradd?-s?/sbin/nologin?nagios?

[root@localhost?~]#mkdir?/usr/local/nagios?

[root@localhost?~]#chown?–R??nagios.nagios?/usr/local/nagios?

（2）開啟系統sendmail服務?

?????????在nagios監控服務器上開啟sendmail服務的主要作用是讓nagios在檢測到故障時可以發送報警郵件，目前幾乎所有的linux發行版本都默認自帶了sendmail服務，所以，在安裝系統時只需開啟sendmail服務即可，并且不需要在sendmail上做任何配置。?

2、?編譯安裝Nagios?

[root@localhost?~]#?tar?-zxvf?nagios-3.2.0.tar.gz?

[root@localhost?~]#?cd?nagios-3.2.0?

[root@localhost?nagios-3.2.0]#./configure?--prefix=/usr/local/nagios??

#指定nagios的安裝目錄，這里指定nagios安裝到/usr/local/nagios目錄?

[root@localhost?nagios-3.2.0]#make?all??

[root@localhost?nagios-3.2.0]#make?install???????

#?make?install用來安裝nagios的主程序,CGI和HTML文件?

[root@localhost?nagios-3.2.0]#?make?install-init???

#通過make?install-init命令可以在/etc/rc.d/init.d目錄下創建nagios啟動腳本?

[root@localhost?nagios-3.2.0]#?make?install-commandmode??

#通過make?install-commandmode命令來配置目錄權限?

[root@localhost?nagios-3.2.0]#?make?install-config???

#make?install-cofig命令用來安裝nagios示例配置文件,這里安裝的路徑是/usr/local/nagios/etc?

3、??安裝Nagios插件?

[root@localhost?nagios]#tar?–zxvf??nagios-plugins-1.4.14.tar.gz?

[root@localhost?nagios]#cd??nagios-plugins-1.4.14?

[root@localhost?nagios-plugins-1.4.14]#./configure?--prefix=/usr/local/nagios?

[root@localhost?nagios-plugins-1.4.14]#?make?

[root@localhost?nagios-plugins-1.4.14]#?make?install?

?????????安裝完成，在/usr/local/nagios下的libexec目錄下，生成很多可執行文件，這些正是nagios所需要的插件。?

4、安裝與配置apache和php?
apache和php不是安裝nagios所必須的，但是nagios提供了web監控界面，通過web監控界面可以清晰的看到被監控主機、資源的運行狀態，因此，安裝一個web服務是很必要的。?
需要注意的是，nagios在nagios3.1.x版本以后，配置web監控界面時需要php的支持。這里我們下載的nagios版本為nagios-3.2.0，因此在編譯安裝完成apache后，還需要編譯php模塊，這里選取的php版本為php5.3.2。?

（1）安裝apache與php?

首先安裝apache，步驟如下：?

[root@nagiosserver?~]#?tar?zxvf?httpd-2.0.63.tar.gz?

[root@nagiosserver?~]#cd?httpd-2.0.63?

[root@nagiosserver?~]#./configure??--prefix=/usr/local/apache2?

[root@nagiosserver?~]#make?

[root@nagiosserver?~]#make?install?

接著安裝php，步驟如下：?

[root@nagiosserver?~]#?tar?zxvf?php-5.3.2.tar.gz?

[root@nagiosserver?~]#cd?php-5.3.2?

[root@nagiosserver?~]#./configure??--prefix=/usr/local/php?\?

>--with-apxs2=/usr/local/apache2/bin/apxs?

[root@nagiosserver?~]#make?

[root@nagiosserver?~]#make?install?

從安裝步驟可知，apache安裝路徑為/usr/local/apache2，而php安裝路徑為/usr/local/php。?

（2）配置apache?

找到apache配置文件/usr/local/apache2/conf/httpd.conf??

找到：?

User?nobody?

Group?#-1?

修改為?

User?nagios?

Group?nagios?

然后找到?

DirectoryIndex?index.html?index.html.var?

修改為?

DirectoryIndex?index.html?index.php?

接著增加如下內容：?

AddType?application/x-httpd-php?.php?

為了安全其間，一般情況下要讓nagios的web監控界面必須經過授權才能訪問，這需要增加驗證配置，即在httpd.conf文件最后添加如下信息：?

#setting?for?nagios?

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/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>?

（3）創建apache目錄驗證文件?

在上面的配置中，指定了目錄驗證文件htpasswd，下面要創建這個文件：?

?????????[root@localhost?nagios]#/usr/local/apache2/bin/htpasswd?\?

>-c?/usr/local/nagios/etc/htpasswd?nagiosadmin??

?????????New?password:?(輸入密碼)?????

?????????Re-type?new?password:?(再輸入一次密碼)?????

?????????Adding?password?for?user?nagiosadmin?

?????????這樣就在/usr/local/nagios/etc目錄下創建了一個htpasswd驗證文件，當通過http://ip/nagios/訪問時就需要輸入用戶名和密碼了。?

?????????最后，啟動服務：

[root@?nagiosserver?~]#/usr/local/apache2/bin/apachectl??start

[root@?nagiosserver?~]#/usr/local/nagios/bin/nagios?–d?/usr/local/nagios/etc/nagios.cfg?start

5、使用check_esx3.pl腳本監控esx、esxi、vcenter

perl環境準備?yum?install?–y?*perl*?openssl-devel

（1）在Nagios服務端上安裝VMware-vSphere-Perl-SDK-4.1.0-254719.x86_64.tar.gz?(到vmware官方網站去下載，如果是32位操作系統，就安裝i386的)

[root@localhost?vmware-vsphere-cli-distrib]#?perl?vmware-install.pl??#安裝VMware-vSphere-Perl-SDK

（2）安裝插件

下載?wget?http://search.cpan.org/CPAN/authors/id/S/SF/SFINK/Math-Calc-Units-1.07.tar.gz

[root@localhost?Math-Calc-Units-1.07]#perl?Makefile.PL

[root@localhost?Math-Calc-Units-1.07]#make?&&?make?install

下載，wget?http://search.cpan.org/CPAN/authors/id/T/TO/TONVOON/Nagios-Plugin-0.34.tar.gz

[root@localhost?Nagios-Plugin-0.34]#?perl?Makefile.PL

[root@localhost?Nagios-Plugin-0.34]#?make?&&?make?install

（3）下載check_esx3.pl并解壓到/usr/local/nagios/libexec/?(wget?http://tangyou.me/wp-content/uploads/2012/06/check_esx3.zip)?

完成~~
