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 -R nagios.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
####Nagios Plugins####
# 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：
#ServerNamewww.example.com:80
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。
