CentosNagios监控平台快速安装

一、首先安装apache：

安装apache，采用yum方式安装，安装的命令是yum install ?y httpd   
安装完apache后，启动apache命令/etc/init.d/httpd restart 即可！ 

二、安装php：

Nagios是基于php语音编写的程序，所以需要安装php，也采用yum方式安装   
Yum install php php-devel -y即可  

三、下载nagios：

现在nagios版本和客户端插件地址如下：   
wget http://sourceforge.net/projects/nagios/files/nagios-3.x/nagios-3.2.1/nagios-3.2.1.tar.gz/download   
wget http://sourceforge.net/projects/nagiosplug/files/nagiosplug/1.4.15/nagios-plugins-1.4.15.tar.gz/download    
wget  http://jaist.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.13/nrpe-2.13.tar.gz    
    
创建用户维护Nagios的用户和组   
useradd nagios   
passwd nagios  

四、在服务器端，安装Nagios和nrpe、nagios插件：

安装Nagios   
tar zxvf nagios-3.2.1.tar.gz   
cd nagios-3.2.1   
./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios   
make all   
make install                   //来安装主程序,CGI和HTML文件   
make install-init              //在/etc/rc.d/init.d安装启动脚本   
make install-config            //来安装示例配置文件,安装的路径是/usr/local/nagios/etc   
make install-commandmode//来配置目录权限    
make install-webconf     写入配置文件   
    
安装Nagios-plugins   
tar zxvf nagios-plugins-1.4.15.tar.gz   
cd nagios-plugins-1.4.15   
./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios   
make && make install   
安装nrpe    
tar -xzf nrpe-2.13.tar.gz && cd nrpe-2.13 &&./configure --enable-ssl --with-ssl-lib &&make all && make install-plugin && make install-daemon && make install-daemon-config   
chown  -R nagios:nagios /usr/local/nagios/    
  
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d  启动nrpe服务  

五、创建web 访问用户：

增加访问控制验证用户：（第一次创建时要加参数c）   
htpasswd -c /usr/local/nagios/etc/htpasswd.users  nagiosadmin   
  
nagios安装完毕，然后重启apache，重启nagios，/etc/init.d/nagios restart   
访问：http://localhost/nagios/ 即可！ 即可访问到nagios最初安装界面  

六、在客户端安装nrpe、nagios-plugin：

首先下载nagios-plugins-1.4.15.tar.gz和nrpe-2.13.tar.gz，   
    
执行如下脚本即可：   
#!/bin/sh   
###auto make install nagios_plugin and nrpe   
useradd nagios   
tar -xzf nagios-plugins-1.4.15.tar.gz &&cd nagios-plugins-1.4.15 &&./configure --prefix=/usr/local/nagios &&make &&make install   
    
sleep 2   
    
echo "This is make install nrpe ,please waiting .................."   
cd ../ ; tar -xzf nrpe-2.13.tar.gz && cd nrpe-2.13 &&./configure --enable-ssl --with-ssl-lib &&make all && make install-plugin && make install-daemon && make install-daemon-config   
    
chown  -R nagios:nagios /usr/local/nagios/   
cd .. ;cp nrpe.cfg /usr/local/nagios/etc/nrpe.cfg   
    
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d   
    
###Add auto start   
grep "nrpe" /etc/rc.local   
    
if [ $? -ne 0 ];then   
echo "/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d" >>/etc/rc.local   
else   
echo "nrpe is exist"   
fi   
保存即可！
