安裝配置nagios

一、安裝nagios前的準備工作

1.解決安裝Nagios的依賴關系：Nagios基本組件的運行依賴于httpd、gcc和gd

2. 所需要安裝組件：

服務端所用的安裝包為 nagios nagios-plugins

linux客戶端 nrpe

windows客戶端 NSClient++

二.下載需求軟件

nagios主程序：wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.13.tar.gz

nagios插件程序：wget http://down1.chinaunix.net/distfiles/nagios-plugins-1.4.13.tar.gz

apache程序：wget http://autosetup1.googlecode.com/files/httpd-2.2.11.tar.gz

php程序：wget http://museum.php.net/php5/php-5.3.0.tar.gz

三.編譯安裝nagios

1.tar zxf nagios-3.1.2.tar.gz

[root@localhost nagios-3.1.2]#   cd nagios-3.1.2

[root@localhost nagios-3.1.2]#./configure --enable-event-broker--prefix=/usr/local/nagios

[root@localhost nagios-3.1.2]#make all

[root@localhost nagios-3.1.2]#make install

[root@localhost nagios-3.1.2]#make install-init

[root@localhost nagios-3.1.2]#make install-config

[root@localhost nagios-3.1.2]#make install-commandmode

在httpd的配置文件目錄(conf.d)中創建Nagios的Web程序配置文件：

  [root@localhost nagios-3.1.2]# make install-webconf

創建一個登錄nagiosweb程序的用戶，這個用戶帳號在以后通過web登錄nagios認證時所用：

# htpasswd -c/var/www/nagios/etc/htpasswd.users nagiosadmin

2.編譯安裝nagios-plugins

nagios的所有監控工作都是通過插件完成的，因此，在啟動nagios之前還需要為其安裝官方提供的插件。

tar zxf nagios-plugins-1.4.13.tar.gz

[root@localhost nagios-plugins-1.4.13]#cd nagios-plugins-1.4.13

[root@localhost nagios-plugins-1.4.13]#./configure --with-nagios-user=nagios --with-[root@localhost nagios-plugins-1.4.13]#nagios-group=nagios -with-mysql

[root@localhost nagios-plugins-1.4.13]#make

[root@localhost nagios-plugins-1.4.13]#make install

4.配置并啟動Nagios

/etc/init.d/nagios start

注：如果啟動時會報錯

Error: Cannot open main configuration file '/root/nagios-plugins-1.4.13/start' for reading!

Nagios 3.1.2 starting... (PID=14327)

Local time is Fri Feb 28 02:52:22 CST 2014

Bailing out due to one or more errors encountered in the configuration files. Run Nagios from the command line with the -v option to verify your config before restarting. (PID=14327)

使用： /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg檢查配置文件沒有發現錯誤

可使用：/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg 嘗試啟動

啟動成功之后 可以使用top命令查看是否有nagios進程（有nagios進程說明啟動成功）
