CentOS MINI环境下Nagios基本安装

t434111

环境：

1、CentOS 6.6 x64 mini安装

2、系统软件有Apache、Php、Nagios、nagios-plugins

PS：

1、mini安装以后的环境缺少很多组件，需逐一完善后才能安装

2、CentOS环境下需关闭防火墙 #service iptables stop

3、CentOS环境下关闭Selinux

/etc/selinux/config文件中设置SELINUX=disabled

4、CentOS配置环境时需能访问公网，便于后续做yum安装

初始化环境：

#yum install -y wget

#yum install -y gcc glibc glibc-common gd gd-devel xinetd openssl-devel

#yum install -y libxml2

#yum install  -y libxml2-devel

# yum install perl

#yum install -ynet-snmp*

需要下载的组件

# wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.4.3.tar.gz

# wget http://nagios-plugins.org/download/nagios-plugins-1.4.16.tar.gz

#wget http://archive.apache.org/dist/httpd/httpd-2.2.23.tar.gz

#wget http://cn2.php.net/distributions/php-5.4.10.tar.gz

创建Nagios组与用户

# useradd -s/sbin/nologin nagios

# mkdir/usr/local/nagios

# chown -Rnagios.nagios /usr/local/nagios

各组件的编译安装

####Nagios####

#tar zxvf nagios-3.4.3.tar.gz

#cd nagios-3.4.3

#./configure --prefix=/usr/local/nagios

#make all

# make install

#make install-init

# make install-commandmode

#make install-config

#chkconfig --add nagios

#chkconfig --level 35 nagios on

#chkconfig --list nagios

####NagiosPlugins####

#tar zxvf nagios-plugins-1.4.16.tar.gz

#cd nagios-plugins-1.4.16

#./configure --prefix=/usr/local/nagios

#make && make install

####Apache####

#tar zxvf httpd-2.2.23.tar.gz

#cd httpd-2.2.23

#./configure --prefix=/usr/local/apache2

#make && make install

####PHP####

#tar zxvf php-5.4.10.tar.gz

#cd php-5.4.10

#./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs

#make && make install

修改apache配置

vi/usr/local/apache2/conf/httpd.conf

找到：

Userdaemon
Group daemon

修改为

Usernagios
Group nagios

然后找到

<IfModuledir_module>
DirectoryIndex index.html
</IfModule>

修改为

<IfModuledir_module>
DirectoryIndex index.html index.php
</IfModule>

接着增加如下内容：

AddTypeapplication/x-httpd-php .php

找到：

#ServerName[url=]www.example.com:80[/url]

在下面增加如下内容（CentOS是服务器的hostname）

ServerNameCentOS:80

在文件最后面增加下面内容：

#settingfor nagios

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"

     AuthUserFile/usr/local/nagios/etc/htpasswd

     Require valid-user

</Directory>

创建apache目录访问权限

#/usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd NagiosLoginName

其中NagiosLoginName是访问用户，最后重复输入2次密码

启动apache

/usr/local/apache2/bin/apachectlstart

此时，基本可以通过http://ip/nagios/来访问Nagios，并进行下一阶段的设置。
