Nagios监控服务器安装和部署

4543

注：

本文档基于nagios+apache的模式，安装nagios时须预先编译安装apache，在此不进行apache编译安装的赘述。

一：配置apache

# vi /usr/local/apache/conf/extra/httpd-vhosts.conf NameVirtualHost *:80 <VirtualHost *:80>     ServerName  192.168.189.132     DocumentRoot "/www"     <Directory "/www">     Order deny,allow     Deny from all     </Directory>     #以下是apache上，nagios所需的配置信息：     Scriptalias/nagios/cgi-bin  /usr/local/nagios/sbin     <directory"/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     </directory>    Alias /nagios /usr/local/nagios/share    <directory"/usr/local/nagios/share">    Authtype basic    Options none    Allowoverride none    Order allow,deny    Allow from all    Authname "nagios access"    //配置nagios用户验证    Authuserfile /usr/local/nagios/etc/htpasswd    Require valid-user    </directory> </VirtualHost>

二：创建nagios用户与组

1 2 3 4

# useradd nagios # groupadd nagios # usermod –a –Gnagios nobody # usermod –a –Gnagios nagios

二：下载nagios相关软件包，并编译安装及环境配置

1 2 3 4 5 6 7

# cd /usr/local/src # wget http://prdownloads.sourceforge.n ... nagios-3.4.1.tar.gz # wget http://prdownloads.sourceforge.n ... ugins-1.4.16.tar.gz # wget http://prdownloads.sourceforge.n ... os/nrpe-2.13.tar.gz # tar -zxvf nagios-3.4.1.tar.gz # tar -zxvf nagios-plugins-1.4.16.tar.gz # tar -zxvf nagios/nrpe-2.13.tar.gz

编译安装nagios

1 2 3 4 5 6 7

# cd nagios-3.4.1/ # ./configure --prefix=/usr/local/nagios --with-command-group=nagios # make all # make install # make install-init # make install-commandmode # make install-config

编译安装nagios插件
# cd ../nagios-plugins-1.4.16
# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios
# make && make install
编译安装nrpe

1 2 3 4

# cd ../nrpe-2.13 # ./configure --prefix=/usr/local/nagios # make all # make install-plugin

设置nagios目录权限

1	# chown –R nagios:nagios /usr/local/nagios/

配置用户密码访问

1 2 3 4

# /usr/local/apache/bin/htpasswd -cm /usr/local/nagios/etc/htpasswd nagiosadmin New password: Re-type new password: Adding password for usernagiosadmin

三：启用nagios，并访问测试
开启apache服务

1	# /usr/local/apache/bin/apachectl -k start

检测nagios配置文件语法是否正确

1	# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

若语法正确，则可以正常启动nagios

1	# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg -d

(也可使用系统服务方式启动：service nagios start)

页面访问测试

出现以上页面，说明nagios安装部署成功。后续需在服务中添加主机与服务，方能开始进行监控。
