分类:CentOS教程 阅读:67890 次

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

wgethttp://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

/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commit

centos6.5下yum安装 nagios监控

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
