                                              **概要设计**

战神咖按照业务功能分成以下几个分区:普通上网区、游戏区、包厢区、视频区、商务区，各个分区部署在不同VLAN。IP网段分别为172.16.1.0/24——172.16.5.0/24。网吧的客户机采用千兆接入局域网，交换机带有万兆上行接口。出于安全考虑，网吧部署了监控系统，并由PoE交换机集中供电，采集的视频存储于网络硬盘录像机供调取。根据需要网吧在CentOS6.5上架设了流媒体服务器用于存放电影，音乐和视频游戏，部署DHCP服务为各功能分区统一提供IP地址等管理。网管系统和计费系统采用单独的软件部署在Windows7上，采用硬件防火墙设置访问策略和过滤规则来优化网吧内外网环境，网吧采用100M电信和50M联通的双WAN出口规划，以实现冗余和流量均衡。
根据以上要求给出设计方案，设备选型，拓扑设计，IP规划，产品配置，应用服务器配置，设计结果验证。

                                                **网络设计拓扑图**

应用服务的功能配置
一、CentOS 6.5下的dhcp服务：
1、安装CentOS6.5：
修改网卡地址为静态
#vi /etc/sysconfig/network-scripts/ifcfg-eth0
ONBOOT=yes
IPADDR=192.168.177.177
PREFIX=16
GATEWAY=192.168.198.2
BOOTPROTO=static
DNS1=202.101.224.68
#service network restart
#service iptables stop
#sed -I ‘SELINUX=enforcing/SELINUX=disabled/g’ /etc/selinux/config
1、查询并安装DHCP服务

rpm -qa | grep dhcp

#yum -y install dhcp*
2、修改DHCP的配置文件
#cp -p /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf
cp:overwrit’/etc/dhcp/dhcp.conf’? y
#vi /etc/dhcp/dhcpd.conf //在命令模式下，按下G 到最后一行，添加：

3、启动DHCP服务，查询相关进程和端口
修改完配置文件后，需要重启DHCP服务
#service dhcpd restart //重启DHCP的服务
#chkconfig --level 35 dhcpd on //配置在相关的运行级别上启动DHCP
#ps -aux | grep dhcpd //查询DHCP进程
#netstat -aultp | grep dhcpd //查询DHCP服务端口号服务器端 67
#pgrep dhcpd //客户端 68
4、DHCP客户端验证
设置DHCP主机网络连接模式为VMnet1，再用一台主机设置网络连接模式为VMnet1，编辑网卡配置
#vi /etc/sysconfig/network-scripts/ifcfg-eth0
ONBOOT=yes
BOOTPROTO=dhcp
其他的不用加，然后
#ifconfig -a
就能看到获取到的IP了。
在windows主机的网卡上设置，自动获取IP和自动获取DNS
或者 c:>ipconfig /release
ipconfig /renew
服务器端查询地址租约数据库
#cat /var/lib/dhcpd/dhcpd.leases
#tail -n 10 /var/lib/dhcp/dhcpd.leases
二、流媒体服务安装
yum -y install gcc gcc-c++ glibc glibc-devel make nasm pkgconfig lib-devel openssl-devel expat-devel gettext-devel libtool mhash.x86_64 perl-Digest-SHA1.x86_64 git wget autoconf automake
#cd /usr/local/src
用wget 添加下面的网址
下载nginx http://nginx.org/download/nginx-1.6.2.tar.gz下载pcre （支持nginx伪静态）
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.36.tar.gz
下载openssl（nginx扩展） http://www.openssl.org/source/openssl-1.0.1j.tar.gz
下载zlib（nginx扩展） http://zlib.net/zlib-1.2.8.tar.gz
#git clone https://github.com/arut/nginx-rtmp-module.git 我是直接用下载好的镜像包安装的
1、安装pcre

cd /usr/local/src

mkdir /usr/local/pcre

tar zxvf pcre-8.36.tar.gz

cd pcre-8.36

#./configure --prefix=/usr/local/pcre && make && make install
2、安装openssl
#cd /usr/local/src
#mkdir /usr/local/openssl
#tar zxvf openssl-1.0.1j.tar.gz
#cd openssl-1.0.1j
#./config --prefix=/usr/local/openssl && make && make install
#vi /etc/profile
#export PATH=$PATH:/usr/local/openssl/bin
#source /etc/profile
2、安装zlib
#cd /usr/local/src
#mkdir /usr/local/zlib
#tar zxvf zlib-1.2.8.tar.gz
#cd zlib-1.2.8
#./configure --prefix=/usr/local/zlib && make && make install
4、安装nginx
#cd /usr/local/src
#tar zxvf nginx-1.6.2.tar.gz
#cd nginx-1.6.2
#./configure --prefix=/usr/local/nginx --without-http_memcached_module --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-openssl=/usr/local/src/openssl-1.0.1j --with-zlib=/usr/local/src/zlib-1.2.8 --with-pcre=/usr/local/src/pcre-8.36 --add-module=/usr/local/src/nginx-rtmp-module
注意：–with-openssl=/usr/local/src/openssl-1.0.1j --with-zlib=/usr/local/src/zlib-1.2.8 --with-pcre=/usr/local/src/pcre-8.36指向的是源码包解压的路径，而不是安装的路径，否则报错
#make && make install
#/usr/local/nginx/sbin/nginx //启动Nginx
设置nginx开机启动
#vi /etc/rc.d/init.d/nginx //编辑启动文件添加下面内容
#!/bin/sh

#nginx - this script starts and stops the nginx daemon

在浏览器中打开服务器IP地址：192.168.177.177，可以看到下面的结果。

编辑原有的nginx.conf中加入如下配置：
#vi /usr/local/nginx/conf/nginx.conf
rtmp {
server {
listen 192.168.177.177：1935;
chunk_size 4000;
#HLS
# For HLS to work please create a directory in tmpfs (/tmp/app here)
# for the fragments. The directory contents is served via HTTP (see
# http{} section in config)
#
# Incoming stream must be in H264/AAC. For iPhones use baseline H264
# profile (see ffmpeg example).
# This example creates RTMP stream from movie ready for HLS:
#
# ffmpeg -loglevel verbose -re -i movie.avi -vcodec libx264
# -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
# -f flv rtmp://localhost:1935/hls/movie
#
# If you need to transcode live stream use ‘exec’ feature.
#
application hls {
live on;
hls on;
hls_path /usr/local/nginx/html/hls;
hls_fragment 5s;
}
}
}
http {
server {
listen 8080;
location /hls {
# Serve HLS fragments
types {
application/vnd.apple.mpegurl m3u8;
video/mp2t ts;
}
root html;
expires -1;
}
}
}

其中rtmp部分与原有的http部分在同一个级别，但是下面的http部分要放到已有的http部分中，也就是增加一个server部分。
然后运行如下命令检查nginx.conf是否有语法错误
service nginx configtest
重新加载配置文件
service nginx reload
运行下面的命令查看nginx状态
service nginx status
注意，这里reload并不能开启这几个服务，需要使用
service nginx restart
将rtmp服务和hls服务的端口1935和8080都打开
然后查看端口
netstat -nlp
一定要关闭防火墙，不然obs连不上
5.下载一个obs程序用于推流，或者在安装的时候添加安装FFmpeg用于推流
方法：在设置-串流里填上：rtmp：//192.168.177.177:1935/hls，密钥就填你要推送的文件或电影名，我填的是：movie，然后就在浏览器里输入：http://192.168.177.177:8080/hls/movie.m3u8 ,就能看到推送的东西了。
