Nagios

前期任务

1 添加用户并修改密码

#useradd nagios

#useradd apache

#passwd nagios

2、创建一个用户名为nagcmd用于web接口执行外部的命令，将nagios用户和apache用户都加入到这个组中！

#groupaddnagcmd

#usermod –Gnagcmd nagios

#usermod –Gnagcmd apache

 

首先做之前弄好gcc  为了不出意外的错。

yum –yinstall gcc*

Apache的安装与配置

yum –yinstall httpd

记得去http.conf里面修改如下：

User  nagios

Groupnagios

 

PHP安装！

[root@localhostlib]# yum -y install php

Loadedplugins: rhnplugin, security

然后进行部署nagios

#tar zxvfnagios-3.0.4.tar.gz

#cdnagios-3.0.4

#./configure--with-command-group=nagcmd

#make all

安装二进制运行程序、初始化脚本、配置文件样本并设置运行目录权限

#makeinstall

#makeinstall-init

 

#makeinstall-config

#makeinstall-commandmode

#makeinstall-webconf

 

编译与安装nagios-plugins

 

#tar zxvfnagios-plugins-1.4.13.tar.gz

#cdnagios-plugins-1.4.13

#./configure --enable-ssl  --enable-command-args     发现checkingfor redhat spopen problem…  停住

 

./configure--with-nagios-user=nagios --with-nagios-group=nagcmd --enable-ssl  --enable-command-args  --enable-redhat-pthread-workaround

 

#make all

#makeinstall

chkconfig--add nagios

chkconfignagios on

基本客户化配置

更改email地址nagiosadmin的联系人定义信息中的Email信息为你的Email信息以接收报警内容！

#vi/usr/local/nagios/etc/objects/contacts.cfg

time_change_threshold=600

验证Nagios的样例配置文件

#/usr/local/nagios/bin/nagios–v /usr/local/nagios/etc/nagios.cfg

如果没有报错的话，可以启动Nagios服务！

#/usr/local/nagios/bin/nagios–d /usr/local/nagios/etc/nagios.cfg

配置Web接口：

修改apache的httpd.conf文件

添加如下内容。

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.users

Require valid-user

</Directory>

Alias /nagios /usr/local/nagios/share

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.users

Require valid-user

</Directory>

配置apache的BASIC认证  创建一个nagiosadmin的用户位于Nagios的WEB就扣登陆

具体路径按照你的apache的安装自行修改：

#/usr/local/apache/bin/htpasswd–c /usr/local/nagios/etc/htpasswd.users nagiosadmin

启动apache

Servicehttpd restart

登陆Web接口

http://localhost/nagios/

如图所示：

OK

大家有一点一定要注意：

>在Centos系统下安装nagios最后可能出现这种报错：“You don't have permissionto access /nagios/ on this server”。

其实这种错误就是提示你没有权限访问nagios这项服务。造成这种报错的原因有多种，可能是文件权限你没有改成777，也可能是你httpd.conf这个配置文件有问题等，但还有一个问题是你想不到的。就是系统环境，注意访问nagios页面，这个nagios页面需要php支持。如果你没有安装php也会提示：You don't have permission to access /nagios/ on this server这个错误的。yum -y install php 。OK这样就能访问nagios页面了。
