利用两台服务器搭建SRS伪集群-手摸手记录

前提

为什么是只有两台呢?因为一直在调研，客户不可能会给6-8台服务器你去搭建SRS集群，所以只能利用最小的资源去验证可行性~手摸手教学，如果有用的话记得给我发个小红包吧(在线乞讨)

设备ip 功能 备注
10.80.210.103 源站+边缘+(nginx+keepalive-主) 端口：
源站集群：
rtmp:11935
http_api:11985
边缘集群
rtmp:21935
http_api:21985
http_server:28080
vip:10.80.210.105
nginx使用端口：
tcp:
1935–> 源站 rtmp
1985–> 源站 http_api
1936–> 边缘站 rtmp
1986–> 边缘站 http_api

http：
80–> 边缘站 http_server
10.80.210.104 源站+边缘+(nginx+keepalive-从) 端口：
源站集群：
rtmp:11935
http_api:11985
边缘集群
rtmp:21935
http_api:21985
http_server:28080
vip:10.80.210.105
tcp:
1935–> 源站 rtmp
1985–> 源站 http_api
1936–> 边缘站 rtmp
1986–> 边缘站 http_api

http：
80–> 边缘站 http_server

目标就是服务器既做源站也做边缘，从而实现高可用…

过程

安装基于SRS4.0服务省略..

源站集群配置

源站集群使用端口说明：

  1. rtmp:11935
  2. http api:11985

10.80.210.103

进入cd /usr/local/srs/conf目录创建origin.cluster.conf 配置文件

# main config for srs.
# @see full.conf for detail config.

#监听的流端口
listen              11935;
#最大连接数
max_connections     1000;
pid                 ./objs/origin_cluster.pid;
srs_log_tank        file;
#srs_log_level       trace;
srs_log_level       warn;
srs_log_file        ./objs/origin.cluster.log;
daemon              on;
http_api {
    enabled         on;
    listen          11985;
}
vhost __defaultVhost__ {
    hls {
        enabled         on;
        hls_fragment    10;
        hls_window      60;
        hls_path        ./objs/nginx/html;
        hls_m3u8_file   [app]/[stream].m3u8;
        hls_ts_file     [app]/[stream]-[seq].ts;
    }
    http_remux {
        enabled     on;
        mount       [vhost]/[app]/[stream].flv;
    }
    cluster {
        #集群的模式，对于源站集群，值应该是local。
        mode            local;
        #是否开启源站集群
        origin_cluster  on;
        # 源站集群中的其他源站的HTTP API地址
        coworkers       10.80.210.104:11985;
    }
}

10.80.210.104

同103配置内容，但差异就是 coworkers 那边需要指向103

# main config for srs.
# @see full.conf for detail config.

srs_log_level       warn;
srs_log_file        ./objs/origin.cluster.log;
daemon              on;
http_api {
    enabled         on;
    listen          11985;
}
vhost __defaultVhost__ {
    hls {
        enabled         on;
        hls_fragment    10;
        hls_window      60;
        hls_path        ./objs/nginx/html;
        hls_m3u8_file   [app]/[stream].m3u8;
        hls_ts_file     [app]/[stream]-[seq].ts;
    }
    http_remux {
        enabled     on;
        mount       [vhost]/[app]/[stream].flv;
    }
    cluster {
        #集群的模式，对于源站集群，值应该是local。
        mode            local;
        #是否开启源站集群
        origin_cluster  on;
        # 源站集群中的其他源站的HTTP API地址
        coworkers       10.80.210.103:11985;
    }
}

keepalived安装和配置

安装keepalived

yum install -y keepalived

修改配置文件

cp /etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf.bak

vi /etc/keepalived/keepalived.conf

103服务的配置文件信息：
global_defs {
   # 路由id：当前安装keepalived的节点主机标识符，保证全局唯一

    }
        # 调用监控脚本
    track_script {
        check_web
    }
}

编写nginx监控脚本

如果nginx服务停止，keepalived服务也停止，并切换到备主机

脚本如下：vi /etc/keepalived/check_web.sh

#!/bin/bash

num=`ps -C nginx --no-header |wc -l`
if [ $num -eq 0 ]
then
    systemctl restart nginx

    sleep 10

    num=`ps -C nginx --no-header |wc -l`
    if [ $num -eq 0 ]
    then
        systemctl stop keepalived
    fi
fi

授权：chmod +x /etc/keepalived/check_web.sh

启动、开机自启keepalived服务

systemctl start keepalived
systemctl enable keepalived

    常说手把手教。手摸手教是不是太涩涩了。
