nagios监控公司内部主机配置

2024-12-21 技术教程

一.实验描述

系统：SUSE Linux Enterprise 10 64-bitnagios服务器IP：192.168.1.122所需软件：nagios-3.2.0.tar.gz nagios-cn-3.2.0.tar.bz2 nagios-plugins-1.4.15.tar.gz apache2-2.2.3-16.21 apache2-mod_php5-5.2.5-9.20二.安装nagios主程序1.创建用户及目录并设定权限#groupadd nagios#useradd -g nagios nagios#mkdir /usr/local/nagios#chown -R nagios.nagios /usr/local/nagios2.编译安装# tar zxvf nagios-3.2.0.tar.gz# cd nagios-3.2.0/# ./configure --prefix=/usr/local/nagios/ --with-gd-lib=/usr/local/lib --with-gd-inc=/usr/local/include/报错

解决方法：安装GCC，如下显示表示正常

# make all 出现以下提示，然后按照提示逐步安装就OK

# 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-commandmode //配置目录权限

# make install-config //安装示例配置文件，安装的路径是/usr/local/nagios/etc

# make install-webconf

3.验证时否安装成功切换目录到/usr/local/nagios/查看是否有以下几个文件存在，如果存在则表示程序被正确的安装到系统上啦

bin nagios执行程序所在目录，nagios文件既为主程序etc nagios配置文件位置，初始安装完后，只有几个*.cfg文件sbin nagios cgi文件所在目录。也就是执行外部命令所需文件所在的目录share nagios网页文件所在的目录var nagios日志文件，spid等文件所在目录三.安装插件1.编译安装# tar zxvf nagios-plugins-1.4.15.tar.gz# cd nagios-plugins-1.4.15/# ./configure --prefix /usr/local/nagios/

# make && make install

# ls /usr/local/nagios/libexec/ \\显示一下内容表示插件安装成功

四.安装apache2

# vim /etc/apache2/uid.conf\\修改成一下内容

# vim /etc/apache2/httpd.conf \\在最后面添加一下内容

ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin <Directory "/usr/local/nagios/sbin"> Options ExecCGI AllowOverride None Order allow,deny Allow from all AuthName "nagios access" AuthType Basic AuthUserFile /usr/local/nagios/etc/htpasswd Require valid-user </Directory> Alias /nagios /usr/local/nagios/share <Directory "/usr/local/nagios/share"> Options None AllowOverride None Order allow,deny Allow from all AuthName "nagios access" AuthType Basic AuthUserFile /usr/local/nagios/etc/htpasswd Require valid-user </Directory> # /usr/sbin/htpasswd2 -c /usr/local/nagios/etc/htpasswd shilong

重启apache和nagios，输入访问地址http://192.168.1.100/nagios五.监控局域网主机（windows和linux都行）1.修改nagios主配置文件# cd /usr/local/nagios/etc# vim nagios.cfg

2.添加配置文件# vim /usr/local/nagios/etc/objects/hosts.cfg

define host { host_name 192.168.1.1 alias Hillstone Firewall\\别名 address 192.168.1.1 \\填写被监控主机IP contact_groups admins \\这个值是来自contacts.cfg文件里面,contactgroup_name后面的值 check_command check-host-alive max_check_attempts 5 notification_interval 10 notification_period 24x7 notification_options d,u,r }

# vim /usr/local/nagios/etc/objects/servers.cfg

define service { host_name 192.168.1.1 service_description check-host-alive check_period 24x7 max_check_attempts 4 normal_check_interval 3 retry_check_interval 2 contact_groups admins\\此处的值同上 notification_interval 10 notification_period24x7 notification_options w,u,c,r check_command check-host-alive \\检查主机是否存活 }

如果监控多个主机只需要在hosts.cfg添加多个host,并在servers.cfg里面也添加相关配置3.配置报警发送邮件# vim /usr/local/nagios/etc/objects/contacts.cfg

六.配置所遇到的报错1.如果这里打开页面出现403错误，证明你的php没有安装（我这里就安装啦一个apache2-mod_php5-5.2.5-9.20然后把相关的依赖包都安装上去啦）。重启apache，nagios页面就出来啦。2.nagiosweb页面提示It appears as though you do not have permission to view information for any of the services you requested...打开cgi.cfg配置文件，里面有个参数:
use_authentication=1
为了保障系统的安全性，nagios设置了这个参数，默认为1,改为0即可3页面显示

查看nagios进程是否启动。如果没有则进行以下操作/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg4.nagios页面有部分是乱码,如图:

发现是apache配置文件的编码问题修改/etc/apache2/httpd.conf最后添加AddDefaultCharsetutf-8
