一、监控服务器安装
1.关闭SELINUX
# vi /etc/selinux/config
SELINUX=disabled
2. 使用yum 安装依赖包
# yum install -y gcc glibc glibc-common gd gd-devel xinetd openssl-devel
# yum install -y libxml2-devel
3.创建nagios用户和用户组
# useradd -s /sbin/nologin nagios
# mkdir /usr/local/nagios
# chown -R nagios.nagios /usr/local/nagios
4. 编译安装Nagios
# wget http://sourceforge.net/projects/nagios/files/nagios-3.x/nagios-3.5.1/nagios-3.5.1.tar.gz
# tar zxvf nagios-3.5.1.tar.gz
# cd nagios
# ./configure --prefix=/usr/local/nagios
# make all
# make install
# make install-init
# make install-commandmode
# make install-config
# chkconfig --add nagios
# chkconfig --level 35 nagios on
# chkconfig --list nagios
5. 安装Nagios 插件
# wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.16.tar.gz
# tar zxvf nagios-plugins-1.4.16.tar.gz
# cd nagios-plugins-1.4.16
# ./configure --prefix=/usr/local/nagios
# make && make install
6. 安装与配置Apache和Php
Apache 和Php 不是安装nagios 所必须的，但是nagios提供了web监控界面，通过web监控界面可以清晰的看到被监控主机、资源的运行状态，因此，安装一个web服务是很必要的。
需要注意的是，nagios在nagios3.1.x版本以后，配置web监控界面时需要php的支持。这里我们下载的nagios版本为nagios-3.5.1，因此在编译安装完成apache后，还需要编译php模块，这里选取的php版本为php5.5.3。
a. 安装Apache
# wget http://archive.apache.org/dist/httpd/httpd-2.2.25.tar.gz
# tar zxvf httpd-2.2.25.tar.gz
# cd httpd-2.2.25
# ./configure --prefix=/usr/local/apache2
# make && make install
b. 安装Php
# wget http://cn2.php.net/distributions/php-5.5.3.tar.gz
# tar zxvf php-5.5.3.tar.gz
# cd php-5.5.3
# ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs
# make && make install
c. 配置apache
找到apache 的配置文件/usr/local/apache2/conf/httpd.conf
# vim /usr/local/apache2/conf/httpd.conf
找到：
User daemon
Group daemon
修改为
User nagios
Group nagios
然后找到
DirectoryIndex index.html
修改为
DirectoryIndex index.html index.php
接着增加如下内容：
AddType application/x-httpd-php .php
为了安全起见，一般情况下要让nagios 的web 监控页面必须经过授权才能访问，这需要增加验证配置，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"
AuthType Basic
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd
Require valid-user
Alias /nagios "/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
d. 创建apache目录验证文件
在上面的配置中，指定了目录验证文件htpasswd，下面要创建这个文件：
# /usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd admin
设置admin的密码
这样就在/usr/local/nagios/etc 目录下创建了一个htpasswd 验证文件，当通过http://192.168.1.108/nagios/ 访问时就需要输入用户名和密码了。
e. 查看认证文件的内容
# cat /usr/local/nagios/etc/htpasswd
启动服务
/usr/local/apache2/bin/apachectl start
检查
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
h.
如果出现
It appears as though you do not have permission to view information for any of the hosts you requested...
编辑cgi.cfg文件
此文件用来控制相关cgi脚本，如果想在nagios的web监控界面执行cgi脚本，例如重启nagios进程、关闭nagios通知、停止nagios主机检测等，这时就需要配置cgi.cfg文件了。
由于nagios的web监控界面验证用户为admin所以只需在cgi.cfg文件中添加此用户的执行权限就可以了，需要修改的配置信息如下：
default_user_name=admin
authorized_for_system_information=nagiosadmin,admin
authorized_for_configuration_information=nagiosadmin,admin
authorized_for_system_commands=admin
authorized_for_all_services=nagiosadmin,admin
authorized_for_all_hosts=nagiosadmin,admin
authorized_for_all_service_commands=nagiosadmin,admin
authorized_for_all_host_commands=nagiosadmin,admin
7.安装HP的check_hpasm
#wget http://labs.consol.de/download/shinken-nagios-plugins/check_hpasm-4.6.3.2.tar.gz
#tar zxvf check_hpasm-4.6.3.tar.gz
#cd check_hpasm-4.6.3
#./configure --prefix=/usr/local/nagios
#make&&make install
8.安装dell的check_openmanage
# wget http://folk.uio.no/trondham/software/check_openmanage.html#download
# tar zxvf check_openmanage-3.7.11.tar.gz
# cd check_openmanage-3.7.11
# cp check_openmanage /usr/local/nagios/libexec/
9.安装snmp
yum --nogpgcheck install http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
yum install perl-Net-SNMP
二、HP服务器的客户端安装
1.下载软件包http://downloads.linux.hp.com/SDR/downloads/
hp-health-8.7.0.22-17.rhel6.x86_64.rpm
hpacucli-8.70-8.0.noarch.rpm
hp-snmp-agents-8.7.0.23-17.rhel6.x86_64.rpm
2.安装hp检测hp服务器硬件健康状态包和检测hp服务器磁盘阵列状态包
# rpm -ivh hp-health-8.7.0.22-17.rhel6.x86_64.rpm
# rpm -ivh hpacucli-8.70-8.0.noarch.rpm
提示安装依赖包
# yum installlibc.so.6 libgcc_s.so.1libstdc++.so.6
安装成功，启动服务
/etc/init.d/hp-health start
/etc/init.d/hp-asrd start
3.安装pciutils
# yum installpciutils*
4.安装SNMP
# yum install net-snmp
# vim /etc/snmp/snmpd.conf
增加一行
dlmod cmaX /usr/lib64/libcmaX64.so
修改
view all included .1
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
access notConfigGroup ""any noauth exact all all none
# service snmpd start
# chkconfig snmpd on
# rpm -ivh hp-snmp-agents-8.7.0.23-17.rhel6.x86_64.rpm
/etc/init.d/hp-snmp-agents start
然后在监控服务器测试
/usr/local/nagios/libexec/check_hpasm -H 172.16.8.15 -C public
三.安装dell服务器
1.下载dell osma
# wget -q-O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash
# yum install srvadmin-all –y
启动服务
/opt/dell/srvadmin/sbin/srvadmin-services.sh start
2. 安装snmp
# yum -y install net-snmp
# vim /etc/snmp/snmpd.conf
修改
view all included .1
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
access notConfigGroup ""any noauth exact all all none
启动服务器
/etc/init.d/snmpd restart
然后在监控服务器测试
/usr/local/nagios/libexec/check_openmanage -H 172.16.8.18 -C public
windows的就不介绍了
