环境：VMware Workstation虚拟机，Server：192.168.118.128 

Server环境：CentOS-6.6 nagios-4.1.1  httpd-2.4.20  php-5.6.22

Server安装：

useradd nagios  创建用户

mkdir /usr/local/nagios
chown -R nagios:nagios /usr/local/nagios?

tar -xzvf nagios-4.1.1.tar.gz.gz
cd nagios-4.1.1

make
make test
make install<br>  cp php.ini-development /usr/local/lib/php.ini  #php配置

配置apache，文件位置：usr/local/apache2/conf/http.conf

将进程启动用户改为nagios，即：

User  nagios

Group nagios

LoadModule php5_module        modules/libphp5.so  # 去掉此行前面注释

找到DirectoryIndex 增加 index.php

并新增SetHandler application/x-httpd-php 使其支持解析php

在最后新增nagios配置：

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>

因为指定了访问验证文件，所以需要创建一个：

/usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd 【登录用户名自己设置】回车后输入设置的密码即可

设置完成可以启动nagios和apache了

出现的问题：

本地可访问，局域网内其他主机不可访问，报no router，此时是防火墙挡住了，可以关掉server防火墙：service iptables stop 或者新增一条放开监听端口80（http.conf）的规则：iptables -I INPUT -p tcp --dport 80 -j ACCEPT

到此server安装完成，当然为了监控其他主机还需要配置相应的nagios文件。
