近段時間一直在研究nagios監控系統，借鑑了很多高手的文章，費了很多功夫總算把它搞定了，如下就是具體的安裝過程，更深層的監控項目還有待進一步研究，但願你們給點建設！！
#===========================安裝 Nagios    ========================================
cd /opt
groupadd nagios
groupadd nagcmd
useradd nagios -g nagcmd -d /usr/local/nagios
chown nagios.nagios /usr/local/nagios/
chmod 755 /usr/local/nagios
wget [url]http://osdn.dl.sourceforge.net/sourceforge/nagios/nagios-3.0.2.tar.gz[/url]
tar -zxvf nagios-3.0.2.tar.gz
cd nagios-3.0.2
./configure --with-command-group=nagcmd
make all
make install
make install-init
make install-config
make install-commandmode
/usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

#============================安裝nagios plugins=========================
cd /opt
wget [url]http://osdn.dl.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.11.tar.gz[/url]
tar -zxvf nagios-plugins-1.4.11.tar.gz

./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-gourp=nagios --with-mysql=/usr/local/mysql5/ --enable-perl-modules
make
make install
#配置和啓動nagios
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
#若是提示「Whoops!   Error: Could not read object configuration data! 」，這是由於沒有啓動nagios後臺進程，執行如下命令
/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
#=============================安裝nrpe 插件==============================
#對遠程一臺linux主機進行監控
#監控服務器上安裝設置
cd /opt
wget [url]http://www.mirrors.wiretapped.net/security/network-monitoring/nagios/nrpe-2.8.1.tar.gz[/url]
#監控主機上安裝方法
tar -zxvf nrpe-2.8.1.tar.gz
cd nrpe-2.8.1
./configure
make all
make install
make install-plugin    ---監控機須要安裝check_nrpe這個插件,被監控機並不須要
##########################################################################
#被監控主機上安裝方法
cd /opt
useradd nagios -d /usr/local/nagios

vi /usr/local/nagios/etc/nrpe.conf
allowed_hosts=192.168.8.150
#爲了監控swap在nrpe.cfg中添加
command[check_swap]=/usr/local/nagios/libexec/check_swap -w 20% -c 10%
command[check_sda1]=/usr/local/nagios/libexec/check_disk -w 20 -c 10 -p /dev/sda1
#sdb1可根椐實際狀況更改，我這裏的硬盤類型是scsi
vi /etc/services
#增長nrpe
nrpe            5666/tcp                        # nrpe
#啓動nrpe
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
netstat -at|grep nrpe
netstat -an|grep 5666
#############################################################################
#再對監控服務器進行設置
#添加nrpe的定義
vi /usr/local/nagios/etc/objects/commands.cfg
# 'check_nrpe ' command definition
define command{
        command_name check_nrpe
        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
        }
vi /usr/local/nagios/etc/cgi.cfg
把use_authentication=1修改成use_authentication=0若是出現頁面沒法顯示之類的
authorized_for_system_commands=nagiosadmin,kerry    --kerry爲http訪問受權用戶
authorized_for_all_services=nagiosadmin,kerry
authorized_for_all_hosts=nagiosadmin,kerry
authorized_for_all_service_commands=nagiosadmin,kerry
authorized_for_all_host_commands=nagiosadmin,kerry
#測試NRPE是不然正常工做
/usr/local/nagios/libexec/check_nrpe -H localhost
killall nagios
/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
echo "/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg –d"  >> /etc/rc.local
ehco "/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg" >>/etc/rc.local
#問題：notifications for this service have been disabled

#問題：Status Map頁面沒法顯示
#解決方法：ln -s /usr/local/lib/libgd.so.2 /usr/lib/libgd.so.2
vi /usr/local/nagios/etc/nagios.cfg
#添加

#emos-mailserver.cfg這個文件名能夠自定義
#對剛定義的emos-mailserver.cfg文件進行配置

#配置完後，重啓nagios

#=============================安裝  pnp===============================================
cd /opt
tar zxvf pnp-0.4.12.tar.gz
cd pnp-0.4.12
./configure --with-nagios-user=nagios \

#錯誤提示：RRDs Perl Modules:                *** NOT FOUND ***

#要產生圖形數據還需在commands.cfg中重定義命令：

#==========================監控遠程windows主機==================================
#監控windows服務器
wget [url]http://nchc.dl.sourceforge.net/sourceforge/nscplus/NSClient++-Win32-0.3.5.zip[/url]
解壓nsclient++0.3.3.zip到c盤根目錄
解壓爲C:\NSClient++
 
#在nagios監控服務器上
vi /usr/local/nagios/etc/nagios.cfg
cfg_file=/usr/local/nagios/etc/objects/windows.cfg 去掉這句話的註釋
 
#到win服務器上，打開命令窗口，cd到剛纔解壓的目錄
#在命令行界面執行 nsclient++ /install
#而後 nsclient++  SysTray 若是出錯不用管！
#此時在「服務」裏面已經有了nsclient的服務
雙擊打開,點"登陸"標籤,在"容許服務與桌面交互"前打勾
#編輯NES.ini，在 [modules] 選項裏，去掉全部的註釋符號； 除了
CheckWMI.dll和RemoteConfiguration.dll
#the [Settings] 選項裏
修改allowd_host=192.168.8.150(nagios服務器的ip)
#[NSClient] 裏面，去掉port=12489的註釋！他靠端口12489偵聽，因此防火牆要打開這個端口！
在[Settings]部分設置'password'選項來設置密碼,做用是在nagios鏈接過來時要求提供密碼.這一步是可選的,我這裏方便起見跳過它,不要密碼.
#而後啓動nsclient
nsclient++ /start
#接下來咱們開始配置nagios服務器裏面的內容
vi /usr/local/nagios/etc/objects/windows.cfg
define host{
    use windows-server
    host_name winserver alias
    My Windows Server
    address 192.168.8.151   --windows服務器的IP地址
    }
#修改hostname和address，很重要！！
#從新啓動監控服務器上的nagios
killall nagios
service nagios start
#==============================安裝  sengEmail ==================================
#使用sendEmail發送報警郵件
cd /opt
wget [url]http://caspian.dotconf.net/menu/Software/SendEmail/sendEmail-v1.55.tar.gz[/url]
tar -zxvf sendEmail-v1.55.tar.gz
cd sendEmail-v1.55
cp sendEmail /usr/local/bin
chmod +x /usr/local/bin/sendEmail
#sendEmail使用方法
/usr/local/bin/sendEmail –f [email]kerry.hu@3aaa.com[/email] –t [email]kerry.hu@3aaa.com[/email] –s mail.3aaa.com –u 「from nagios」 –xu [email]kerry.hu@3aaa.com[/email] –xp 11111 –m happy
#解釋:-f 表示發送者的郵箱
     -t 表示接收者的郵箱
     -s 表示SMTP服務器的域名或者ip
     -u 表示郵件的主題
     -xu 表示SMTP驗證的用戶名
     -xp 表示SMTP驗證的密碼(注意,這個密碼貌似有限制,例如我用d!5neyland就不能被正確識別)
     -m 表示郵件的內容若是你不帶-m參數的話,就會提示你自行輸入
#編輯配置文件，nagios使用sendEmail來發警告郵件
vi /usr/local/nagios/etc/objects/commands.cfg
# 'notify-host-by-email' command definition
define command{
 command_name notify-host-by-email
 command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/local/bin/sendEmail –f [email]kerry.hu@3aaa.com[/email] –t $CONTACTEMAIL$ –s mail.3aaa.com –u "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" –xu [email]kerry.hu@3aaa.com[/email] –xp 11111
 }
# 'notify-service-by-email' command definition
define command{
 command_name notify-service-by-email
 command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /usr/local/bin/sendEmail –f [email]kerry.hu@3aaa.com[/email] –t $CONTACTEMAIL$ –s mail.3aaa.com –u "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" –xu [email]kerry.hu@3aaa.com[/email] –xp 111111
 }
#注：在使用sendEmail的過程當中沒法發送報警郵件，不知是什麼緣由，只好改用系統自帶的sendmail發郵件！！
