微信多群直播服务器,基于srs直播群集架构之一路rtmp推流，多rtmp拉流

基于srs直播群集架构之一路rtmp推流，多rtmp拉流

一、架构设计

1、基础网络设施架构

2、一台目标推流的服务器，负责直播的源存储转发(origin)

3、一台loadbalance服务器，负责边界拉流服务器的负载调度(loadbalance)

4、两台realserver服务器，参与负载调度的边界拉流服务器(edge)

5、参与负载调度的服务器可以横向扩展

6、架构设计图，见下图

二、环境说明

所有服务器系统：centos-6.7-x86_64 Linux内核2.6.32

推流系统：网络摄像头作为视频源(rtsp)，obs采集视频并推流(rtmp)

直播服务器软件: srs(simple-rtmp-server) SRS-CentOS6-x86_64-2.0.205.zip

loadbalance软件： ipvsadm-1.26-4.el6.x86_64 && keepalived-1.2.13-5.el6_6.x86_64

三、系统实现

1、推流服务器配置，即srs-origin

网卡配置：eth2:172.16.1.207/24

srs服务器配置：

a.安装srs服务器，默认安装后路径 /usr/local/srs

cd  /usr/local/src

unzip SRS-CentOS6-x86_64-2.0.205.zip

./ INSTALL

b.修改配置文件ln -s /usr/local/srs /etc/srs

vim origin.conf

listen              1935;

max_connections     1000;

pid                 objs/origin.pid;

srs_log_file        ./objs/origin.log;

vhost __defaultVhost__ {

gop_cache       off;

queue_length    10;

min_latency     on;

mr {

enabled     off;

}

mw_latency      100;

tcp_nodelay     on;

}

将/etc/init.d/srs 启动脚本中srs.conf  修改为origin.conf

c.启动srs服务

service srs start

2、loadbalance服务器配置，即loadbalance

网卡配置eth2:172.16.1.208/24  eth2:0:172.16.1.200/24

网络参数配置：vim /etc/sysctrl.conf  修改 net.ipv4.ip_forward = 1

安装调度器软件ipvsadm&&keepalived ：yum install ipvsadm keepalived -y

配置keepalived：vim /etc/keepalived/keepalived.conf

! Configuration File for keepalived

global_defs {

notification_email {

}

notification_email_from keepalived@localhost

#smtp_server 192.168.200.1

#smtp_connect_timeout 30

}

vrrp_instance VI_1 {

state MASTER

interface eth2

advert_int 1

authentication {

auth_type PASS

auth_pass 1111

}

}

}

virtual_server 172.16.1.200 1935 {

delay_loop 6

lb_algo rr

lb_kind DR

nat_mask 255.255.255.0

persistence_timeout 50

protocol TCP

real_server 172.16.1.211 1935 {

weight 1

TCP_CHECK {

connect_timeout 3

nb_get_retry 3

delay_before_retry 3

}

}

}

启动服务和保存配置：service network restart  service ipvsadm start   service keepalived start

3、realserver1服务器配置，即srs-edge1

网卡配置：eth2:172.16.1.211/24  lo:0:172.16.1.200/32

网络参数配置：vim /etc/sysctrl.conf  修改 net.ipv4.ip_forward = 1  添加                                                                                                                   net.ipv4.conf.all.arp_ignore=1

net.ipv4.conf.all.arp_announce=2

添加本地路由：route add -host 172.16.1.200 dev lo:0

srs服务器配置：

a.安装srs服务器，默认安装后路径 /usr/local/srs

cd  /usr/local/src

unzip SRS-CentOS6-x86_64-2.0.205.zip

./ INSTALL

b.修改配置文件ln -s /usr/local/srs /etc/srs

vim edge.conf

listen              1935;

vhost __defaultVhost__ {

mode            remote;

origin          172.16.1.228:1935;

}

将/etc/init.d/srs 启动脚本中srs.conf  修改为edge.conf

c.启动srs服务,并重启网卡服务

service srs start  service network restart

4、realserver2服务器配置，即srs-edge2
