一、Nagios服务端安装

1、yum install –y httpd php mysql mysql-devel

2、服务器端安装nagios程序

wget [http://sourceforge.net/projects/nagios/files/nagios-3.x/nagios-3.2.1/nagios-3.2.1.tar.gz/download][http_sourceforge.net_projects_nagios_files_nagios-3.x_nagios-3.2.1_nagios-3.2.1.tar.gz_download]

[http://down1.chinaunix.net/distfiles/nagios-plugins-1.4.14.tar.gz][http_down1.chinaunix.net_distfiles_nagios-plugins-1.4.14.tar.gz]

/usr/sbin/useraddnagios

tar zxvfnagios-3.2.1.tar.gz

cdnagios-3.2.1

./configure--prefix=/usr/local/nagios --with-command-group=nagios

make all

make install;makeinstall-init;make install-config;make install-commandmode ;make install-webconf

makeinstall //来安装主程序,CGI和HTML文件

makeinstall-init //在/etc/rc.d/init.d安装启动脚本

makeinstall-config //来安装示例配置文件,安装的路径是/usr/local/nagios/etc

makeinstall-commandmode //来配置目录权限

makeinstall-webconf // 配置nagios跟apache整合

3、安装Nagios-plugins插件，监控用

tar zxvfnagios-plugins-1.4.14.tar.gz

cdnagios-plugins-1.4.14

./configure--prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios

make&& make install

4、服务器端安装nrpe,与客户端通信

tar -xzf nrpe-2.14.tar.gz

cd nrpe-2.14

./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

5、nagios访问控制设置

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

输入两次密码即可,登录页面的时候会用到这个密码.

6、重启nagios、httpd服务

重启前

/usr/local/nagios/bin/nagios-v /usr/local/nagios/etc/nagios.cfg 检测是否正确

重启nagios,/etc/init.d/nagios restart ;/etc/init.d/httpd restart ;

7、Nagios测试访问 用户名：nagiosadmin

http://localhost/nagios/ 如下图：

点击左侧的Hosts可以看到右侧默认localhost主机的监控，UP表示主机目前运行正常：

点击左侧的Services可以看到右侧默认localhost监控的各个服务的状态，绿色OK表示正常：

取消[![wKiom1YTgeCgccE9AAAViyqjWVI343.jpg][]][wKiom1YTgeCgccE9AAAViyqjWVI343.jpg]大喇叭，

点击大喇叭图标-- Enable notifications forthis service

点commit

[![wKiom1YTgfbx7wIHAABqHCzYMAo446.jpg][]][wKiom1YTgfbx7wIHAABqHCzYMAo446.jpg]

Error:Could not opencommand file '/usr/local/nagios/var/rw/nagiosNaNd' for update! 错误提示没有权限，

授权这个文件 chmod 777 /usr/local/nagios/var/rw/nagiosNaNd

出现错误：

HTTP WARNING:HTTP/1.1 403 Forbidden - 5159 bytes in 0.002 second response time(警告：HTTP HTTP / 1.1没有权限访问此网站-0.002秒的响应时间5159个字节)

新建网页index.html并授权

chmod o+w/var/www/html/index.html

二、Nagios监控客户端安装

1、安装nagios-plugins

useradd -s /sbin/nologin nagios

tar -xzf nagios-plugins-1.4.14.tar.gz

cd nagios-plugins-1.4.14

./configure --prefix=/usr/local/nagios

&&make &&make install

2、客户端安装nrpe

tar -xzfnrpe-2.14.tar.gz && cd nrpe-2.14 &&

./configure--enable-ssl --with-ssl-lib &&

make all

makeinstall-plugin && make install-daemon && makeinstall-daemon-config

chown-R nagios:nagios /usr/local/nagios/

启动nrpe客户端命令：

/usr/local/nagios/bin/nrpe-c /usr/local/nagios/etc/nrpe.cfg -d

3、客户端nrpe设置

vi /usr/local/nagios/etc/nrpe.cfg

在allowed\_hosts=127.0.0.1 字段后面加上nagios服务器端的IP地址

allowed\_hosts=127.0.0.1,192.168.1.151或者allowed\_hosts=127.0.0.1,192.168.1.0/24
