Nagios监控服务器安装和部署

鸦鸦

　　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

    ServerName  192.168.189.132
    DocumentRoot "/www"
   
    Order deny,allow
    Deny from all
   
    #以下是apache上，nagios所需的配置信息：
    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"
   //配置nagios用户验证
   Authuserfile /usr/local/nagios/etc/htpasswd
   Require valid-user
   
　　

　　
　　二：创建nagios用户与组
# 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
# cd /usr/local/src
# wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.4.1.tar.gz
# wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.16.tar.gz
# wget http://prdownloads.sourceforge.net/sourceforge/nagios/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
# 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
# cd ../nrpe-2.13
# ./configure --prefix=/usr/local/nagios
# make all
# make install-plugin　　设置nagios目录权限
# chown –R nagios:nagios /usr/local/nagios/　　配置用户密码访问
# /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
# /usr/local/apache/bin/apachectl -k start　　检测nagios配置文件语法是否正确
# /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
# /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。
