監(jiān)控軟件----CentOS6下安裝配置nagios

CentOS下主要監(jiān)控軟件的區(qū)別可參考http://os.51cto.com/art/201104/252820.htm

在這里總結(jié)下nagios的安裝配置.

1.安裝必要組件:

yum -y install httpd php php-gd freetype php-mysql php-snmp php-devel mysql mysql-server perl-DBD-MySQL php-pdo net-snmp net-snmp-libs net-snmp-utils net-snmp-devel ruby ruby-devel gcc glibc glibc-common gd gd-devel ntp openssl openssl-devel

2.關(guān)閉selinux和iptables.

3.安裝nagios:

----創(chuàng)建nagios用戶和組:

[root@web1 ~]# useradd nagios
[root@web1 ~]# groupadd nagcmd
[root@web1 ~]# usermod –a -G nagcmd  nagios

----下載nagios程序和nagios插件

[root@web1 ~]# wget http://jaist.dl.sourceforge.net/project/nagios/nagios-3.x/nagios-3.5.0/nagios-3.5.0.tar.gz

[root@web1 ~]# wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.16.tar.gz

----解壓nagios程序和插件

[root@web1 ~]# tar zxvf nagios-3.5.0.tar.gz

[root@web1 ~]# tar zxvf nagios-plugins-1.4.16.tar.gz

----安裝nagios程序

[root@web1 ~]#cd nagios

[root@web1 nagios]#./configure --with-command-group=nagcmd

[root@web1 nagios]#make all

[root@web1 nagios]#make install

[root@web1 nagios]#make install-init

[root@web1 nagios]#make install-config

[root@web1nagios]#make install-commandmode

[root@web1 nagios]#make install-webconf

注意:

make install 用于安裝主要的程序、CGI及HTML文件
make install-init 用于生成init啟動腳本
make install-config 用于安裝示例配置文件
make install-commandmode 用于設(shè)置相應(yīng)的目錄權(quán)限
make install-webconf 用于安裝Apache配置文件

復(fù)制eventhandlers:

[root@web1 nagios]# cp -R contrib/eventhandlers/ /usr/local/nagios/libexec/

[root@web1 libexec]# chown -R nagios:nagios /usr/local/nagios/libexec/eventhandlers

校驗nagios配置文件是否配置有誤:

[root@web1 libexec]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

添加修改http訪問頁面用戶nagiosadmin及密碼123456

htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

啟動nagios:

/etc/init.d/nagios start

/etc/init.d/httpd start

----安裝nagios插件

[root@web1 ~]# cd nagios-plugins-1.4.16

[root@web1 nagios-plugins-1.4.16]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios

[root@web1 nagios-plugins-1.4.16]# make

[root@web1 nagios-plugins-1.4.16]# make install

----通過web訪問nagios:
