nagios監(jiān)控網(wǎng)絡(luò)服務(wù)器和網(wǎng)絡(luò)服務(wù)安裝篇
nagios的安裝比較簡單，復(fù)雜的是設(shè)置和配置參數(shù)的設(shè)定。不過你要放松一點(diǎn)，畢竟我們要搞定它，不是嗎？那就開始吧：
1：獲得***的安裝包
下載地址：http://www.nagios.org/download
2：以root身份登錄服務(wù)器
目前***的版本是2.5：
1）nagios，版本2.5：
fetch http://superb-west.dl.sourceforge.net/sourceforge/nagios/nagios-2.5.tar.gz
or
wget http://superb-west.dl.sourceforge.net/sourceforge/nagios/nagios-2.5.tar.gz
2）獲得nagios插件，版本1.4.3：
http://surfnet.dl.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.3.tar.gz
3）獲得圖庫文件：
http://dl.sf.net/nagios/imagepak-base.tar.gz
4）NRPE，版本2.5.2
http://ufpr.dl.sourceforge.net/sourceforge/nagios/nrpe-2.5.2.tar.gz
5）NSCA，版本2.6
http://kent.dl.sourceforge.net/sourceforge/nagios/nsca-2.6.tar.gz
3：切換到root用戶
sudo su
4：解壓縮
tar zxvf nagios-2.5.tar.gz
5：建立運(yùn)行nagios的用戶
adduser nagios
6：建立安裝nagios的文件夾
使這個(gè)文件夾的所有者為nagios:nagios
mkdir /usr/local/nagios
chown nagios.nagios /usr/local/nagios
7：確認(rèn)web服務(wù)器的用戶
可能會(huì)通過web接口執(zhí)行一些命令，必須確定web服務(wù)器以哪個(gè)用戶運(yùn)行的，通常為：apache：
grep "^User" /usr/local/apache2/conf/httpd.conf
8：建立命令文件組
這個(gè)新的組會(huì)包括apache的用戶和nagios的用戶
- pw groupadd nagcmd
- pw usermod apache -G nagcmd
- pw usermod nagios -G nagcmd
- ----------------------------------
- cat /etc/group
- nagcmd:*:9007:apache,nagios
- ----------------------------------
9：運(yùn)行配置腳本并安裝nagios
- cd nagios-2.5
- ./configure --prefix=/usr/local/nagios --with-gd-lib=/usr/local/lib --with-gd-inc=/usr/local/include
- ---------------------------------
- *** Configuration summary for nagios 2.5 07-13-2006 ***:

10：安裝nagios-plugins
- tar zxvf nagios-plugins-1.4.3.tar.gz
- cd nagios-plugins-1.4.3
- ./configure --prefix=/usr/local/nagios-plugins
- make all
- 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/
11：imagepak-base.tar.gz的安裝
tar –xvzf imagepak-base.tar.gz
解壓以后是base目錄
mv base/ /usr/local/nagios/share/images/logos/
nagios的安裝過程到這就結(jié)束了，您的操作一定要認(rèn)真和準(zhǔn)確，若果您對nagios還不是很熟悉，推薦您先看一下nagios監(jiān)控網(wǎng)絡(luò)服務(wù)器和網(wǎng)絡(luò)服務(wù)概念篇做一個(gè)初步，這樣會(huì)使得服務(wù)配置更順利地進(jìn)行。若果您的主機(jī)已經(jīng)準(zhǔn)備好以上工作，我們就開始配置nagios，參見：故障解決篇和配置篇
